larva was not discovered, but it should prove to be a species of 

 Fulgoridae (the normal host of the Epipyropidae), The known 

 species of Epipyropidae are few and easily separated by structural 

 characters. This new species can be recognized at once by its small 

 size and the enlarged cucullate tegumen of its genitalia. Only two 

 other American species could possibly be confused with it, E. bar- 

 he/iana Dyar from Texas, which differs strikingly in every detail of 

 the genitalia (pi. 2, fig. C), and Oedon/'a exhjua Hy Edwards from 

 Arizona formerly placed in the Psychidae but recently identified 

 as an Epipyropid by Frank Morton Jones,- wlio has sent me a sketch 

 of the venation and antenna of exlgua. They agree substantially 

 with those of cucullata and harheriana. The type of exigua (a 

 female) is in the National Museum collection, and is somewhat larger 

 than the males of either harhenana or cucullata. Mr. Jones has a 

 couple of other specimens, also females. Unfortunately we know 

 only males of harberiana and cucullata and only females of 

 Edwards's species. 



I am inclined to believe that when a male of exigiia is discovered it 

 will prove to be a true Einjyyrops and possibly the same as harheri- 

 ana. The distribution of the two (Texas and Arizona) v/oulcl 

 suggest this. 



Dyar ^ has given a good description of the Epip-grops larva in his 

 paper on E. harberiana, and Jordan * has described and figured the 

 venation and genitalia of several exotic adults ; but so far as I know 

 no one has treated the pupa. I, therefore, include drawings (pi. 2, 

 figs. 8, 9) of the pupa of cucullata. It shows striking similarity 

 (except in its small size and more dilated antennal case) to that of 

 Lagoa in the Megalopygidae. The male genitalia of Epipyropidae 

 resemble most those of the Dalceridae. The two families are closely 

 related, differing in genitalia chiefly in the development of vinculum 

 and anellus. Other obvious genitalic differences in the two families 

 are chiefly of specific or generic significance.
