related, and we have still another form from the Galapagos Islands 

 (reported by Coquillett as Culex tcsniorhynchus, Proc. Wash. Acad. 

 Sci., Ill, 372, 1901). which, however, is in too poor condition to be 

 described. All these forms might, perhaps, be considered geographic 

 races of a single species. 



THE PERICOPID LARVAE IN THE NATIONAL 

 MUSEUM 



{Lepidoptera, Hypsida) 

 By HARRISON G. DYAR 



Gnophaela latipennis Boisduval. 



Larva : Dyar, Proc. Ent. Soc. Wash., iv. 408. 1900. 

 The larvae are uniformly marked, all the segments cross-banded, but 

 the bands fused subdorsally, laterally, and subventrally, until a longitudi- 

 nal type of marking has been evolved. 



Composia fidelissima Herrich-Schaffer. 



Larva : Dyar, Joum. N. Y. Ent. Soc, iv, 70, pi. iii, 1896. 

 Dyar. Proc. Ent. Soc. Wash., iv, 408. 1900. 



The transverse banding is here developed unequally, joints 5, 6, 9, 

 1 0, and 1 1 being banded, the rest without bands, but the marking is 

 not very prominent, tending to disappear in the last stage. 



Composia sybaris Cramer. 



This larva is uniformly banded, pale yellow, the bands on joints 5 to 

 1 I black and blue, on joints 2 to 4 and 12 to 1 3 "red, as are the head 

 and anal shield ; there are subdorsal and subventral rows of quadrate 

 black-purple spots on the segments anteriorly in the incisures of joints 6 

 to 1 1 ; feet broadly red. Hairs sparse, short, black, with single long 

 subdorsal white ones from joints 3 and 1 2 as in Composia fidelissima. 

 Warts also as in that species.
