LEXIS BICOLOR Grote. 



One specimen, Auj^ust 13, normal. 



HYPOPREPIA MINIATA Kirby. 



Twenty-three specimens, July 4, 13, l-t, liS, 31; Aug'ust 1, 3, 5, at 

 light or on leaves in the da3'time. Onl}' the species mbiiata occurred. 

 The absence of fucosa confirms the distinctness of these forms, Avhich 

 were formerly reg'arded as varieties of one species, Th(> lar\a lives 

 on lichens on bark of trees or stones. Eggs were readily deposited by 

 captive females. The larva hibernates when about half grown. 



Egg. — Shape of two-thirds of a sphere, with flat ])ase, scarcely 

 conoidal. Reticular areas flattened, their joinings not raised, yet very 

 distinct, regularly hexagonal, making the surface polyhedral. Shin- 

 ing dark lead color; diameter, 0.8 mm. Laid perfectly loose, rolling 

 about in the dish. 



Stage I. — Head round, bilobed, full, ])rown black; the mouth pale. 

 Body normal, Arctiiform. Tubercles conic, high; all light orange 

 brown. The alimentary canal darker anteriorly; tuljercles concol- 

 orous; setae coarse, stiff, spinulose. Tubercle i small, pale; ii very 

 large, thick, black; the others pale, but rather stout, single; on the 

 thorax ia and ib contiguous, iia also approximate to them, iil) separate. 

 Shield concolorous. 



Stage II. — Head bilobed, ])lack; mouth brown; width, ().;") nun. 

 Body robust, light brown, with tine dark granules, innnaculate. Warts 

 small, colorless; the setge remarkably large and coarse. Feet pale; no 

 shields. Tubercles i and ii single haired, iii with two hairs, iv to vi 

 single and weak; hairs of i to iii are coarse, black, and barbuled. On 

 thorax ia + ib -f iia, iib small, iii and iv approximate, v not very remote. 

 Later the larva l)ecomes dull brown, with a pale, waved subdorsal \'\m\ 



Stage III— Head black; width, 0.65 nun. Body brown, with a light 

 yellowish subdorsal band, incising the dorsal area intersegmentally on 

 its upper side. Hairs black; structure as before. 



The life history was not completed. 



CLEMENSIA ALBATA Packard. 



p:ight specimens, July 4, 15, 29, 31; August 1, 5, (5. 'J'he lar\ le were 

 obtained from eggs laid by a captive female, but the life history was 

 not completed, as the larvie hibernated. They fed on lichens. 



^'^^^.—Spherical, the base scarcely flattened, smooth, neatly reticu- 

 late, the reticulations a little elongate vertically; i)ale yelhnv, sur- 

 rounded by long fine hairs from the moth, whi<'h stand nearly erect; 

 diameter, 0.8 mm. The agg is very large for the sizi^ of the moth. 



Stage I— Hand round, bilobed, shining luteous. dotted with t)l:ick 

 over the vertex, but leaving an elliptical pale i):itch on the suniniil of
