19181 ChamberlinÌÔMyriapod from Nashville, Tennessee 23 of one large one and several smaller ones, IV imbricated and I11 as a rule in part faintly, the whole with a few spinelike hairs; corni- cles very short, tuberculiform; rostrum reaching from somewhat be- yond metacoxa nearly to end of body (relative length, like that of antennae, varying as in the other two species) ; legs stoutish and armed with spinelike hairs, anterior tibise .1540-.I925 mm,, inter- mediate tibiae .1694-.2079 mm., metatibise 2156-2387 mm.; length of body ,4620-,8470 mm., width across widest part 2618- .4004 mm.
A. prunifolioe is the first of the three to begin hatching, and in Virginia it may begin as early as the middle of March. The other
two follow in about ten days to two weeks. MYRIAPODS FROM NASHVILLE, TENNESSEE.
BY RALPH V. CHAMBERLIN,
Museum of Comparative Zoology, Cambridge, Mass. The myriapods listed below are represented in a collection made by Mr. Harold Cummins of Vanderbilt University in and near Nashville and by him kindly sent to me for study. The collection is interesting particularly because it includes numerous well pre- served specimens of a new diplopod genus of the family Nanno- lenidae. Three other forms represent new species, two of Fontaria and one of Parajulus. There is a total of twenty-five species. CHILOPODA.

19181 Chamberlin-Myriapods from Nashville, Tennessee Choctella gen. nov.
A Nannolenid genus which has the usual form and proportions of Spirobolus.
Mandibular combs 7.
Gnathochilarium as in Nannolene and Epinannolene. Ocelli in several series, arranged in a triangular patch. Repugnatorial pores beginning on the sixth somite, each pore in front of the transverse suture of the somite. Antennae short, composed of 7 articles of which the fifth and sixth are clavately enlarged.
Second and third articles longest, subequal; fourth, fifth and sixth but little shorter, subequal. Head below eyes deeply sub- vertically grooved, for the reception of the proximal portion of an- tennse.
Dorsal plate of first somite large, extending forwards on a portion of head and largely concealing the antennae. First and second legs in male reduced in size but armed and otherwise similar to the succeeding pairs. A11 somites excepting the first and last strongly longitudinally striate beneathand almost half way up to the repugnatorial pore, elsewhere smooth.
Posterior border of last segment above rounded, exceeded by the anal valves. Mesa1 edges of anal valves meeting in a distinct groove.
Gonopods well exposed. Gonopods two pairs, coleopods and phallopods respectively, the seminal duct traversing the latter. Each coleopod simple, thin, plate-like, and undivided. Phallopods also undivided.
Genotype : Choctella curnminsi sp. nov.
I
16. Choctella cumminsi sp. nov.
The general color below is black excepting the caudal, over- lapping border of each somite.
Dorsally the somites remain dark
in a more or less narrow band adjacent to this pale posterior border elsewhere bearing greyish yellow or more typically in part reddish, the color rather irregular in arrangement. Ordinarily the light markings of the dorsum are less extensive anteriorly than else- where, the caudal segments also in some being similarly darker than the middle ones. Head in general greyish black. Labrum

and adjacent region of head and narrow borders of first somite also reddish. Antennae blackish. Legs dusky reddish brown. Anal valves reddish brown along their contiguous mesal margins. Body Spirobolus-like in general form and appearance. Of uniform diameter throughout excepting the first few and last few somites. Surface in general appearing smooth and shiny but each somite excepting the first and last marked below on each side with a series of strong longitudinal striae which do not extend up on the sides, the striation extending farther dorsad caudad of the suture than in front of it.
First repugnatorial pore on the sixth somite. Pores large, each
in front of and well removed from the transverse suture. Head with a pronounced vertigial sulcus connected from its anterior end to each eye by means of a finer transverse sulcus. Below this the surface is roughened by singular sulci which are more prominent laterally, but the smooth antennae short, clavate, with the first two articles normally lying in a deep groove in front of and below the eye; first four articles sparsely hairy, the re- maining ones densely clothed; sensory cones pale, distinct. Eyes black, triangular, transversally-elongate; ocelli in 5 or 6 series; 30 to 40 in number. Setigerous foveolse 3 + 3. Plate of first somite large, extending over head to the transverse suture betweens eye and normally covering greater part of an- tennse. Anterior margin curving broadly moderately forward on the sides, the lower anterior corner evenly rounded, the caudal corner projecting somewhat caudad and more narrowly rounded. The lower anterior and the ventral border elevated and set off by a suture, which does not extend across mid-dorsal region. No other distinct sulci.
Last somite a complete annulus much larger above than below with the caudal dorsal margin evenly rounded and surpassed by the anal valves.
Anal valves ventrally smooth.
Seventh somite in male moderately produced below. Genopods well exposed.
Coleopods simple, thin plates, each of which is moderately narrowed distad and narrowly rounded at the apex; below apical portion the mesal border of each is bent subcaudad. Phallopods exceeded by the caleopods. Each with distal division narrowly subconical, distally curving mesad, the tip somewhat obliquely truncate.

19181 Chamberlin-Myriapods from Nashville, Tennessee 27 Number of somites 44 to 48.
Average length near 50 mm. with diameter 4.8 mm. Localities. Glendale Hills, south of Nashville. Nine specimens April 21,1917 and three specimens March 25,1917. 17. Parajulus xenns ylvanicus (Wcoc') .
Beyond Glendale, Oct. 14, 1916. One female apparently this species.
18. Parajulus nigrans sp. nov.
The color is very dark, blackish throughout without definite paler spots or annuli. Feet also dark.
Body rather slender, obviously narrowing caudad. In general
smooth, not pilose, but a few stiff, somewhat curved set= on last segment and anal valves. Somites strongly longitudinally striate beneath and across lower part of sides.
First segment long, with the lower margin straight; margined below and over lower part anteriorly but not at all striate. The anal plate above is acute but is not at all produced; it is clearly exceeded by the anal valves and bears a series of set= along its caudal margin.
Anal valves mesally margined.
Head with a median vertigial sulcus ending at a deeply impressed arcuate transverse sulcus extending between the eyes. Nearly
smooth.
Eyes triangular, each composed of about 36 ocelli ar- ranged in 8 transverse series.
Repugnatorial pore moderate, contiguous or nearly so with the suture which is straight or rarely very slightly curved opposite the pore.
In the male the mandibular stipes strongly produced at the an- tero-inferior angle, the apex of the process being on nearly the same level as the inferior margin of the labrum. Each first gonopod of the male is placed antero-lateral of the corresponding second one. Its anterior division is a flat plate about half as high as the posterior division against which it lies; its distal end is rounded. The second or posterior gonopods rise clearly above the anterior plates. Each above its base is a thin, flat blade with edge subapical, which near its middle curves caudad and then somewhat dorsad. Not at all narrowing dorsad, its free distal end truncate; from the basal portion a slender acutely pointed blade curves mesad and crosses the one from the other side.

19181 Chambedin-Myriapods from Nashville, Tennessee 29 Basal lobe of each gonopod strongly setose on mesa1 side. Ex-
tenor division with setse on posterior edge over basal and middle region; the branchis constricted above here into a slender blade of uniform width until the next to the distal fifth of length over which it is expanded to nearly double the width and then again narrows to a tongue which at its distal end is attenuated into a slender, distally bristle-like tip. About the distal three-fifths, or less, of the exterior blade is strongly bent upon itself roughly into a U-shape, with the slender tip at right angles to the arm bearing it. The

NOTES ON D1PTERA.l
(a) In studying the habits of the "salt-fly" of Great Salt Lake (Ephydra gracilis Pack.) in 1911, I noted that trains crossing the lake on the famous Southern Pacific cutoff west of Ogden raise a constant swarm of these flies for an hour, and many of the insects get into passenger trains in spite of efforts to keep them out by closing the windows. My report says (Jour. N. Y. Ent. Soc., xx, 84, 1912), "They become a nuisance . . . in the dining cars. I had no difficulty in finding some of the flies in the latter situa- tion as far west as Reno, Nev., and I doubt not that they may be found after the cars reach Oakland."
I can now add that the species has established itself in sari Fran- cisco Bay. On July 10, 1917, in sweeping about several little saline pools close to the shore of the Bay next to Palo Alto, I cap- tured 18 specimens, indicating that it is a common species 30 miles south of the Oakland mole. I had no opportunity to examine other portions of the Bay shore.
Prior to the running of trains across Great Salt Lake, which 1Published by permission of the Chief of the U. S. Bureau of Entomology,
