OF WASHINGTON, VOLUME XII, 1910. 175 



Podalia darca, new species. 



Dark brown, the wings rather thinly scaled. Abdomen with dark 

 yellow hair above, but the segments banded with blackish; abdomen 

 below, legs, pectus, and front of head yellow. Expanse, male 35 mm., 

 female 55 mm. 



Three males, one female, Maroni River, French Guiana 

 (W. Schaus). 



Type: No. 13115, U. S. National Museum. 



Allied to Podalia brngea Schaus, but of a darker brown, 

 the abdomen less clear yellow. 



Podalia megalodia, new species. 



Thorax dark brown intermixed with pinkish, the vertex of the head 

 pinkish. Abdomen pale brown with dark segmental rings. Fore wing 

 dark brown streaked with whitish on costa and in cell, denning two 

 dark -brown rays and a spot at the end of the cell; the whitish streak- 

 ing predominates beyond the cell and defines an outer row of elliptical 

 spots between the veins, the two lower of which are sagittate, being 

 incised in the basal side by whitish loops, veins terminally and mar- 

 ginal spottings faintly pale. Hind wings dark brown, a little paler 

 between the veins outwardly. Expanse 85 mm. 



Four males, Rio Janeiro and Petropolis, Brazil (Schaus 

 collection). 



Type: No. 13116, U. S. National Museum. 



I have not found any description of this large and conspicu- 

 ous insect. The freiiultim is partly degenerated, though 

 there is still a small costal loop, while the thorax is not as 

 prominent before the wings as in typical Podalia. The 

 species is therefore transitional toward Megalopyge. The 

 pattern of coloration, while similar to that of orsiloc/ms, has 

 considerably departed from it and suggests that of the 

 alb i colli s group of Megalopyge.

This genus contains a large number of species, some of 

 which I have discussed in separate articles.
