168 ZYG^NID^ AND BOMBYCIDjE 



BOMBYCIDffi. 

 LITHOSIINS. 

 Genus EUSTIXIS. HUbner. 



" Body slender, rather short. Palpi straight, slender, a little shorter 

 than the head ; third joint linear, conical at the tip, a little shorter 

 than the second. Antennae slender, setaceous very minutely pubes- 

 cent. Abdomen extending as far as or a little beyond the hind wings. 

 Legs slender ; hind tibiae with four long spurs. Wings long, narrow. 

 Fore wings very slightly convex in front, conical at the tip, with a 

 somewhat rounded angle behind ; the three inferior veins approximate 

 at the base. Hind wings with four inferior veins ; third approximate 

 at the base, fourth remote." 



Morris, Syn. Lep. N. Am., p. 253. 



This genus bears a strong resemblance to the Ttneina, and might 

 readily be mistaken at first sight for a member of that group. Two 

 species are noted by Walker as found in the United States, though 

 Grote and Robinson in their catalogue of the Bombycida^ suggest that 

 they are probably identical. Having only one species before me, I 

 am not prepared to say which theory is correct. Both insects have 

 reddish secondaries and white primaries, the latter with numerous 

 small dots of black or brown. They may be distinguished thus : 



Spots on primaries black, - - - - E. ptipula. 



Spots on primaries reddish brown, - - - E. sub/erveiis-
