REMARKS ON APATELODES SUGGESTED BY AN ARTICLE 



BY MR. SCHAUS. 



BY HARRISON G. DYAR, A. M., NEW YORK. 



Mr. Schaus, in describing some new species of South American 

 moths (Proc. Zool. Soc, Lond., 1894, p. 233), casually refers the genus 

 Apatelodes to the Eupterotid^e. As this genus has been placed among 

 the Notodontidae by American authors, it may be worth while to examine 

 the arguments for this position. 



The Eupterotidje of Hampson are a series of mostly large moths 

 from India, with geometriform markings, of a peculiar and rather charac- 

 teristic appearance. The body is proportionately rather small and 

 slender, and the fringes of the wings are long. Their hairy vestiture, 

 broad wings and short cell suggest the Lasiocampidae, where they are 

 placed by Kirby. They are, however, frenate, and with the venation 

 essentially of Notodontidie, but without the accessory cell. Two genera, 

 at least, are included (Gangarides and Cnethocampa), which differ con- 

 siderably in habitus. In these, the body is stouter proportionately, the 

 wings are narrower and the cell longer, while the general appearance 

 suggests the Notodontidae rather than the other Eupterotidae. Mr. 

 Hampson separates these families by the absence of the tongue in the 

 Eupterotidae ; but, as this member seems to be equally lacking in the 

 notodontian Melelopha (Ichthyura), the separation seems hardly very 

 sharp. 



Of the larvse, I only know those of Cnethocampa (Thaumetopoea, 

 Hubn.). Unfortunately, these belong to the atypical section just referred 

 to, and it is hardly fair to judge the Eupterotidt^i by these. Very little' 

 can be positively made out from figures, usually ; though that of the larva 

 oi Eupterota fabia seems to exhibit the same type of structure as Cnetho- 

 campa. Judged on these data, the larval Eupterotidfe belong to the 

 Lymantriid section of the Noctuina, characterized by the presence of warts, 

 three warts above stigmatal wart on the last two thoracic segments. They 

 differ from the Lymantriidae by the reduction of wart v. instead of iv. and 

 the presence of secondary hairs. 



To turn now to Apatelodes. In atigelica there is a little accessory 

 cell on a long stalk; but in torrefacta there is none, and veins 7-8 and 

 9-10 arise as two pairs from a short furcation of the long stalk from apex 

 of cell. The hind wings are frenate and the tongue is wanting. The 

 habitus is not that of the typical section of the Eupterotidae, but there is
