NOTE ON LARVAE OF GYNAEPHORA
GROENLANDICA AND G. ROSSII.
BY IIARRISON G. DYAR, WASHIKGTON, D. C.
IN PSYCIIE vii, 328 I referred to Curtis' description of thelarva of .å£aj+Ì rosshnd to the fact that it did not correspond with the larva of rossiz'which I found on the summit of Mt. Washington. The U. S. National
museum hah just received two larvae from West Greenland, north of Wilcox Head, col- lected by R. Stein, which agree with Curtis' brief description. One had pupated and I obtained from it a moth of G.groenlandica, Therefore Curtis must have mixed the
species, describing the moth of rossit and larva of poetiZafzdit.a. Apparently both species occur in Greenland. The mu&um has specimens of rossti from the Florence Arctic expedition and groenlandica from Polaris Hay. The species are probably not coexten- sive, however, as only rossii has been taken on Mt. Wabhington. We have it also from
. Labrador and Point Barrow, Alaska (Mur- dock). As to the larva described by Dr.
Packard, his " hnlf grown larva " is probably groetilvndica ; the '; full fed " one is unlike either.
Larva of G. ~roet~iundica : Head 3.4 mm. wide (male), rounded, dull black, densely covered with long secondary black hairs. Body entirely black, the warts large and griin~ilar, arriingeinent apparently normal with i and iv small, but I cannot !ice
them
distinctly in the shrunken specimens. Re- tractile tubercles on joints 10 and I I whitish. Hair abundant, dull reddish brown, mixed with black. Dorsal tufts present on joints i; to g and 12 as in D. seZewitica, but those - -
on j, 6 and 12 black, on 7, 8 and g deep orange The black tufts are a little longest, projecting beyond the orange hairs and a little beyond the average of the general dorsal coating. Hairs all finely spinulated none plumed.
The smaller specimen has the head 2.5
min. wide.
The pupa resembles that of rossz'i, but the long dorsal hair is more erect and black, not whitish; the shell is thicker, black, and possesses three pair of'long but functionless appendages in. the place of the abdominal legs of joints 8 to 10 which I do not find in the pupa of rossti.
DATES OF ISSUE OF SOME OF B,OIS-
DUVAL'S WORKS.
BY SAMUEL II. SCL'DDER.
THE following data regarding the time of issue of some of the works of the French entomologist, Jean Baptiste Alplionsc Bois- duvfti d'Echauffour (h. 1801, d. 1879) may prove of interebt to special students. They were partly gleaned from different sources in Paris many years ago, partly obtained by reference to the Bibliographic de la France. .,
The Icones historiques dee Lfipidopt&-es d'Europe appeared in 42 livraisons between 1832 and 1843, according to Hagen, The
Prospectus was issued March 17, 1832. The separate llvraisons contained each, as far as I have discovered, from 8-20 pp. of text and 2 plates. Livr. I, 2 appeared Mar. 24, 1832; 3, 4. Mar. 31, 1832; 5, 6, July 7, *a;
7. 8,
Oct. 13, 1832; 9, 10, Jan. 5, 1833; (11-18 not discovered, but doubtless in 1833' ; 19, 20: Jan. 4, 1834; 21, 22, July 26, 1834; 23, 24, May 17, 1834; 25, 26, 27, 28, July 26, 1834 ; 29, 3u, Sept. 27, 1834; 31, 32, Jiin. 17; 18.3.'; ; of the remainder I have no memoranda,
except that livr. 38 was published in the last quarter of 1835. After 1835 there is no men- tion of it in the Bibliographie de la France. The Europaeorum Lepidopter~~um index
methodicus appeared Nov. 22, 1828; it is given as 1829 in Hagen. The 2d ed., entitled Genera et index methodicus europaeorum
Lepidoplerorum, appeared May 9, 1840.
The Faune cntomologique de Madagascar
appeared Sept. 28, 1833; given by Hagen as 1834.

A CURIOUS CASE OF PROTECTIVE
COLORATION.
AT Mesilla, IS?. M.,
on Aug. 15, 1897,
sat down to rest while on a collecting excur- sion; and my eye fell on a clump of the
whitish-green Bailsya witlfiradiafa, with its splendid orange composite flowers. In the middle of the clump was a vanessid pupa, while resting on one of the stems, about to cast its skin, was a sphingid larva. These objects caused me some surprise, as being (so far as J had yet known) foreign to the Bailep, :ind yet harmonizing perfectly with its peculiar color. The pupa wis silver-colot" with a faint greenish tinge and a golden lustre, with the dorsal prominences and part of the antenniil coverings ruddy golden. A
beautiful and conspicuous object in the hand, it was hardly noticeable on the plant. So also with the larva, which was 35 mm. long, pale whitish-green, nearly the color of the foliage; caudal horn very pale blue, with dorsal black specks; seven oblique lateral stripes, spiracular openings orange. Taking' the larva home, I found that it would by no meanseat Baileya, but it fed greedily on the fuliag'e of Solanurn elaeasy~zz~di~~~n. It was, in fact, an immature " tomato worm." The pupa, on Aug. 21, gave forth an ordinary example of Pyramei's carduc the larva must doubtless have wandered from an adjacent Sphaeralcea.
Now are we to suppose that the vanessid
larva came to the Baileysi to pupate, and the sphingid to exuviate, because they reidized that they would be protected (t'. e. inconspic- uous) there?

NOTE ON CYDOSIINAE.
IN VIEW of Mr. Cockerell's note on the
larva of Cydosia (Psyche VIII., 130) we have now at least a partial idea of the young stages of both genera of the Cydosiinae of Smith. Messrs. Hulst and Smith have both remarked on stage I. of Cerathosia (Ent. Amer. V. +8-9), but between the two accounts the essential features seem to have become befogged. The specimens are now before
