MEGALOPYGIDAE 



Megalopyge lapena Schaus. 



In Can. Ent. 1913, p. 185, we recorded the above species from 

 Arizona ; recently, together with Dr. Dyar, we compared one of our 

 y\rizona specimens with Schaus' type in the National Museum and 

 noted that they were not identical ; in the type S there is a distinct 

 small brown patch on primaries at end of cell at the origin of vein 

 5 which in our Arizona specimens (PI. XX, Fig. 12) is reduced quite 

 constantly to a small dark dot which, together with the subapical spot, 

 is rather darker brown than the basal patch ; Druce's figure of lapena 

 in Biol. Cent. Am. Het. PI. 86, Fig. 13, does not bring out very clearly 

 the nature of the discocellular patch which is really much better defined 

 than in the copy before us. For our Arizona form, which we treat 

 as a race rather than a species, we propose the name heteropuncta, 

 our types being 3 S from Chiricahua Mts., Ariz. (Aug.) and 2 $ 

 from Palmerlee, Ariz., and Paradise, Cochise Co., Ariz.
