cate at base, internal vein from between 11 and 10 to between 8 and 

 7. Hind wing over I triangular, 8 veins, 3 and 4 short-stalked, 5, 

 6 and 7 parallel. 



I take pleasure in naming this beautiful species after its discoverer, 

 Dr. Harrison G. Dyar. 



Only one other species of this genus, H. {Siino't/ns^ vicarialis Zel- 

 ler is recorded from North America. This species is unknown to me 

 except from description, but it is evidently entirely different from H. 

 ihari. 



The breeding of this species from Ficiis agrees with the known 

 food-habits of other tropical species of the genus as recorded by 

 Meyrick. 



The genus Jra/s///x'kamia Riley is very near to Hemerophila, differ- 

 ing principally in the thickened antennre. It agrees perfectly in wing 

 form and venation. The difference in labial palpi is so slight that it is 

 unfortunate that Professor Fernald has used it as a differential character 

 in the synoptic table of his valuable paper on. these and allied genera 

 (Can. Ent., 1900, p. 238). He calls the third segment of the labial 

 palpi in ]]\ilsiii}:;hai)iia long and pointed, while I should decidedly 

 call it short and blunt, very little longer indeed than in Hemcropliila. 

 Long and short are relative terms, susceptible of varying interpretation 

 and therefore I think Professor Fernald' s table would have been im- 

 proved by placing Walsinghamia under the same number as Hemero- 

 pJiila and then using the antennal character to separate. 



The common food-plant and peculiar larval habits further confirm 

 the close relationship of these two genera. 



The following are Dr. Dyar's notes on the larva : 



"The larva lives on the leaves of the rubber banyan tree (^Ficus 

 aurea and F. pediincii/ata). When small, on the back of a leaf under 

 a delicate silken tent ; when large on the upper surface under a similar 

 broad web spun flat on the leaf across the slightly concave upper side. 

 The larva eats holes through to the lower epidermis in a patch about 

 half an inch in diameter under the web. These patches remain even 

 on old leaves, showing the characteristic traces of the larva, though 

 the delicate web is evanescent and disappears almost as soon as the 

 larva quits it. The larvDS are very active, falling to the ground with 

 contortions when disturbed. Each remains in its web only long 

 enough to eat one or two patches, when it proceeds to a new leaf to 

 form a fresh web. They are always solitary at maturity, though sev-
