PSYCHE. 



407 



slightly tinged with yellow above, short on 

 disc of mesothorax and sparse on disc of 

 nietathorax. Wings hyaline, veins brown. 

 Legs black, more or less brownish on tibiae 

 and tarsi, the four anterior tibiae white at 

 base and on the anterior pairextending down 

 a short distance in front is a brownish-yellow 

 line; pubescence whitish tinged with yel- 

 low on tarsi beneath. Abdomen black, shin- 

 ing, almost nude except at base where there 

 are some white hairs and at apex where the 

 pubescence is rather dense; yellow bands on 

 segments 1-4, those on 1-2 broadly inter- 

 rupted on the disc and on 3-4 very slightly 

 so ; all are somewhat margined on the lateral 

 apical portions. Venter black, apical margin 

 of the segments brownish. 



Habitat. Visalia, Cal. (H. O. Wood- 

 worth), May 9. One specimen. 



6. Calliopsis anthidius n. sp. — f. 10 

 mm. Black, abdomen with narrow yellow 

 bands broadly interrupted on the sides. 

 Head black, very finely and densely punc- 

 tured on vertex; clothed with whitish pube- 

 scence, tinged with yellow above; all of the 

 face beneath the antennae except three small 



spots on clypeus near the base and one on 

 the labrum, and mandibles except tips, yel- 

 low; the yellow on the sides of the face ex- 

 tends up a little higher than the antennae. 

 Antennae black, flagellum pale yellowish 

 beneath. Thorax entirely black, clothed 

 with a dense whitish pubescence which has a 

 brownish-yellow tinge above. Wings smoky 

 becoming darker toward apical margins; 

 veins black. Legs clothed with short white 

 pubescence; black except a line on the an- 

 terior femora and on all the tibiae in front

 and the tarsi entirely except a narrow black 

 line on posterior pair behind, and the claws 

 which are more or less brownish, yellow. 

 Abdomen black, clothed with a very short 

 pale pubescence; segments 1-5 with narrow 

 yellow bands each slightly interrupted on the 

 middle and broadly so latterly forming thus

 on the sides being the broadest. Venter

LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE. — IV. 



BV HARRISON G. DYAR, WASHINGTON, D. C. 



Therina eudrcpiayia Grl. and Rob. — The 

 mature larva has been described by Goodell 

 (Pan.ent. xi, 194). His description, though 

 short, is correct, if the structures that he calls 

 " tubercles" be understood to be low rounded 

 prominences of the skin and the words 6, 

 8 and 7th segments be changed to 6, S and 

 gth. Further as Goodell does not count the 

 head as joint i, his numbering of the seg- 

 ments should be increased by one in each 

 case to correspond with mine. 



Egg- ■ — Several together, usually in a 

 straight row of 5 tog, sometimes more; ir- 

 regularly elliptical, scarcely flattened, one 

 end distinctly truncate, a little convex with a 



rounded rim. Neatly, distinctly reticulate, 

 the cell areas resembling round pits, the pit- 

 ting extending ajso over the truncate end. 

 Slightly bluish green, shining, soon turning 

 dull reddish with a dark spot on the truncate 

 end. Size .6 x .4 x .3 mm. 



Stage I. Head round, pale brown ; width 

 about .3 mm. Body whitish translucent, a 

 rather broad pale cinerous subdorsal band, 

 leaving the dorsal and lateral areas pale. 

 Setae fine, pointed, white, obscure. Appear- 

 ance pale grayish, obscurely marked. After 

 eating they became translucent green, the 

 head brown, no marks. 



Stage II. Head round, slightly bilobed,
