Valley, Aug. 1-4 ( Scudder ) , Spring Of the spread specimens I have seen, Lake Villa, Utah Co., Utah, Aug. 1-4 all from east of the continental divide, ( Palmer ), and Gazelle, Cal., Sept. 4 have the base of the wings as pellucid ( Morse ) . Besides these states, it has as the distal half ; while in all from been reported from the Yellowstone re- west of this line, the base of the wings is gion ( Bruner ), Dakota (Thomas, washed with pale citron, Brnner ) , and Montana ( Thomas ).

loiw glaitcaria Gue 11.
The larva has
h,
been described (as ~w6ivora Riley) by Riley, Saunderii and French but not in much de- tail.
Egg.
Elliplicaf, strongly flattened on two
sides, the flat faces concave, sunken, the edges well marked but a little rounded; side view slightly wedge shaped, the broader end tmn- cate roundly, elevated in its center so as to be almost quite round like the narrower end, and is so except for a slight annular flatten- ing, noticeable from side view. Surface all finely hexagonally reticulate, the reticulations not strongly raised. Pale, slightly greenish yellow, shining. Size .6 X -5 X .3 mm.
Later turns pale red.
Stage I. Head round, slightly bilobed,
pale brown, mottled with paler, with shorl, white, glandular setac; width about .3 mm. Body cylindrical, smooth, tubercles rather large, especially iv, which is cylindrical and produced with 21 coniwl tip. Setac white ; on abdamen short with flattened enlarged tips, except iii (of jo.int 5) and iv (joints 6 to 9) which is very long and has a bulbous tip. This seta is sticky and bears, on its base principally, the fragments which adhere to the larva. Subdorsal setae of thorax and joint 12 also prolonged, but much shorter than the long lateral ones. Dark brown-black mot- tled with ocherous, especially on joints 12 and 13, which look lighter; traces of a. dark dorsal line.
Stage fl.
Head rounded, slightly bilobed,
of the color of the body ; width .4 mm.
Body
as before, the setae glandular but much
shorter, iv still the longest and arising from a somewhat produced base. Color dull
brown, a whitish ground speckled with brown. Skin grannlarly roughened. Larva rather
short and thick. Jt becomes entirely covered with fragments of the flowers it feeds on, which adhere to the sticky setae.
Stags III. Head rounded bilobed, clypeiis rather high ; shagreened, setae obscure ; lu- teous whitish, speckled with brown, heaviest near the suture and on the sides of the lobes; width .8 mm. Body thick and robust, dor- sum slightly flattened ; tubercles angularly elevated; sctae small except iv, which is large and arises from an elongated tubercle. No marked lateral projections, the slight angular projcctions nearly alike for all the tubercles. Gray brown, densely frosted with white gt-mules, an obscure, double, white dorsal line, divided by brown; traces of a white lateral band on the angular elevations poste- riorly, on anal plate and anal feet. Tuber- cles pale, setae white. All the dorsnm except thorax and joints 12-13 covered with frag- merits of flowers which adhere to the spiny base of the short stiff seta iii.
Feet pale.

94 PSYCHE. [August, ip>.
Siag'e IV, Head rounded, scarcely bi-
lobed. lower thm prothorax, whitish, dotted with black over the sides and in a double streak on the vertex; width about I mm.
Body short and thick, angular from the ele- vations, but without processes. Tubercle i and ii are high white cones with short, stiffs sctae but with no elevation of the hod? ; iv is a largercone with siniilarseta (i.e. iiiof joint 5, iv of 6 to 9), the tubercle radiately spinuse on its shaft and arising from a slight lateral elevation or swelling of the body; before find a little below it is a smaller smooth white cone bearing &eta iii; v aiid vi remote, simi- lar to iii; upper vii smaller, below iii sub- ventrally; lower vii and viii are prominent on the edge of the venter. Spiracle on the dorsal aspect of the slight bulge that bears tubercle iv on joints 5 to 9. Tubercles of NOTES ON THE NESTING OF
ANTIHIDIUM PAR05ELAE CKLL
I do not know how long this bee had been working before 1 discovered it, but to my knowledge it canied honey and pollen into its neht for two days. The nest was a small round liolc burcd in the hard sand. The bee broiight very sinfill loads of pollen, and uould remain in its nest about45 seconds ench time; it took froiii three to five minutes for it to collect each load, and when it returned it would snil about its nest a short time before entering. Once during the absence of the Anthidiuni a specimen of fifhecodcs forffor Ckll. entered the nest and stayed about half a minute, and then flew out very swiftly, as if it were afraid the Anthidinm would return md doit some harm. I hwi noticed from the beginning that another bee (Ho/ioj+tsites å´ftrodt~c/t~ var. subizther Ckll.) lingered around tlie nest. and would frequently go to theentrance and look in. After a while dur- thorax and joints 12-13 siniiller; on 12, i is absent, ii is large and sticky like iv of 9, iii {s rudimentsiry. Blackish gray; ground color bliickish brown, densely frosted ~ith ronnd flattened, white granules, the prominent tuberelcs whiteand an angular white marking in a double dorsal line, along the angular lateral outline ami subvenlrally, most distinct on joints 12 and i3. Thoracic feet pale; plates large, hut colored and sculptured like the body. All covered with fragments of
petals, adhering to the sticky tubercles. The spiciite's on tlie sticky tubercles are short cylindrical rods with blunt tips. The lan,a hibernated in this stage. full grown appr- ently. Bred at Washington, D.C., from eggs obtained Sept. 21. Earlier broods will give the moth the same season.
Larvae fed on flowers of Aster.
ing the absencc of the Anthidiuin, it took the liberty of going into the nest. but it did not stay long. After the Anthidi~in'i had finished provisioniiig her nebt: she bronchi some wool from Llic steins of plants and filled up the en- trance. When the bee had gone I dug up
the nest and found that it bad stored its pro- visions in wool, the same as that with which it hiid closed up the nest.

[The above obscrviitions, made by Miss
Newberry, a sindent of the i^. M. Agricul- tural College, Eire of interest, becausenothing whatever has been reported heretofore re- giirding the nestingoof any of the insects mentioned. It is peihaps unsafe Lo assert that the Sphecodes and Hoplopasites are par- asitic in the nest of the Anthidiiim, but the facts point to such a conclusion. Theohser- vations were made at me sill:^ Park at the end of May, and I am responsible for the identi- fiwtiou of the insects.-T. D. A. Coderell.]
