ENTOMOLOGY.’ 
Lycznid larva on Atriplex.—On July 6, 1892, I beat several 
small lycenid larvæ from Atriplex canescens, 12 miles north of Cedar 
Ranch, Arizona, on the stage road from Flagstaff to the Grand Cafion. 
The larvz were of almost the same shade of color as the bush and 
leaves, of a very light whitish-green, thus easily escaping detection. If 
I am not mistaken they fed on the underside of the leaves. 
Description of larva.—Length (in strongly curved position), 5 mm.; 
width, 23 mm. Thirteen jointed, strongly curved (after immersion in 
alcohol), arehed, broad, somewhat flattened, tapering to head, more 
rounded posteriorly. In color pale whitish-green, head shining jet 
black ; a median dorsal, and two lateral rows (one on each side) of red- 
dish spots, one spot to each segment, on segments 3 to 10; those on ante- 
rior segments much fainter usually, especially the lateral ones. Often 
a faint row of smaller spots ventrad ofthelateral row. Head very small 
compared with other segments, hardly more than one-third the width of 
the prothoracie segment, within which it is usually retracted; sub- 
hemispherieal in shape, convex dorsally, glabrous, well polished and 
shining. All the other segments thickly covered with minute short — 
white spine-like tubercles, with a less number of similar black ones 
interspersed. These extend on the ventral portion, which is besides 
clothed with some short whitish hairs along sides and on prolegs. The 
anterior portion of dorsum of prothoracic segment is furnished with 
more numerous and larger short and stout black spines. — Prothoracie 
segment subtriangular in outline from above, a little rounded in front, 
widening behind; segments 3 to 6 widening posteriorly, each wider than 
its predecessor; segments 7 to 10 about equal in width, a little wider 
than 6; 11 and 12 gradually narrowing from 10; 13 considerably nar- 
rower than 12 (in some specimens regularly narrowing from 12), 
rounded posteriorly, with a terminal somewhat narrower and partially 
free joint which bears the terminal or anal pair of prolegs. Segments 
3 to 8 each gathered into a transverse, slightly curved, more or less 
hump-like ridge on dorsum, the prothoracic segment with a strongly 
anteriorly bent one, segments 9 to 11 hardly humped, segments 5 to 8 
usually most Fag! 80. Eyes represented by five small glassy simple 
eyes, four of them arranged in a semicircle with the outside antero- 
dorsad, the fifth postero-ventrad of the four. Mandibles minute,
