Felder figures a single female from French Guiana. The 

 dark median shade is well developed, but is well separated 

 from both base and margin. I have several males from this 

 region, close to ornata, briscis, and gornna, but think they 

 are not to be associated with^W//A/. 



Megalopyge govana Schans. 



Megalopyge govana Schaus, Trans. Am. Ent. Soc., xxx, 139, 1904. 



Only the single male type from Omai, British Guiana, is 

 certainly referred here. The wing is heavily overspread with 

 brown, the white markings forming a line bent inward at 

 vein 2. The French Guiana specimens referred to above un- 

 der pellita may belong here, but they are lighter and yellower 

 on the margin. The wing-shape of all is as in briseis, but 

 the specimens are smaller. A good series of both sexes is 

 needed for a positive opinion. 



Megalopyge defoliata Walker.

 Alpis defoliata Kirby, Cat. Lep. Het., 541, 1S92. 



The identification is based upon a female compared by Mr. 

 Schaus with specimens in the British Museum. The species 

 is from Mexico, and I have a number of specimens from that 

 region. It differs from the forms heretofore considered by a 

 whitish patch at the base of the fore wing in both sexes. M. 

 defoliata in a strongly-marked, dark-shaded species, with yel- 

 low margin. 



Megalopyge codiopteris Dyar. 



Also from Mexico. The form is closely allied to defoliata, 

 but throughout lighter, the margin more overspread with 

 brown and less contrasted. 



Megalopyge trujillina Dyar. 



Like the preceding, but still browner, with less ocherous 

 tint, more uniformly colored. 



Megalopyge trujillo Schaus. 



Megalopyge trujillo Schaus, Journ. N. Y. Ent. Soc., iv, :>s. isiiti. 

 Still darker than the preceding, the ocher tint almost wholly 

 lost.
