No.1742. w/ii LEPIDOPTERA FROM MEXICO DYAR. 267 



MEGALOPYGE BISSESA, new species. 



Head and thorax orange yellow, more or less intermixed with brown. 

 Fore wing yellow, the basal two-thirds overspread with brown, 

 mottled with purplish, especially costally, with a brown semidetached 

 spot at the fork of veins 7 and 8. Hind wing with light-brown 

 shading on the basal half. Expanse, male, 30 mm.; female, 45 mm. 



Ten males, two females, Cuernavaca, Mexico, August, 1906 (\Y. 

 Schaus); Santa Rosa, Mexico, July, 1906 (W.Schaus); also one male, 

 southern Arizona (E. J. Oslar), and one female, Oracle, Arizona, July 

 22 (II. G. Hubbard). 



Type.- Cat. No. 13031, I'.S.N.M. 



Allied to Megalopyge ornata Druce and .1/. opercularis Smith and 

 Abbot, l>ut distinguished from both by the clear yellow margin of 

 fore wing, which is not encroached upon by brown shadings. 



MEGALOPYGE LANATA Stoll. 



This species is subject to lather marked local variations. The 

 Mexican form is small and dark, the black marginal shadings not 

 separated, but joined to the submarginal intervenular black streaks. 

 The hind wings are dark, in the female sometimes solidly blackish. 

 Stoll's original figure of the female may be recognized, although I have 1 

 never seen a specimen in which the median markings were so reduced as 

 there represented. The figure of the male is wholly unrecognizable. 

 PltahuiKi citri Sepp is clearly the same species with the median 

 markings well developed but not strongly joined to the basal ones. 

 I am unable, however, to accept the reference of Phalaena Bombyx 

 tharops Stoll to this species, as I can not reconcile any nude specimen 

 before me with Stoll's figure. It probably represents some species 

 at present unrecognized. 



MEGALOPYGE SUPERBA Edwards. 



This species is recorded in the Biologia ( Vnt rali-Americana as 

 (tdsina albicollis Walker. It is, no doubt, only a race of Megalopyge 

 albicollis Walker, hut the wings have very considerably less of while, 

 and I think the name superba may he retained for the Mexican form. 

 I have this same form from British Honduras and Costa Rica.
