present. The Clasp (PI. V, Fig. 8) is remarkably simple; there is no 

 division into Blade and Lobe nor any armature; the ventral margin 

 is well rounded distally, and the dorsal margin curves down to meet 

 it, forming at the junction a rather sharp angle. The Penis (PI. VI, 

 Fig. 12) is straight, with a prominent tooth on the ventral surface near 

 the apex. 



It is possible that Druce's Fig. 3 on PI. 69 of the Biologia repre- 

 sents the 9 of this species; it is certainly not ncumocgciii, a fact which 

 Skinner has already noted, proposing the name drucci (Tr. Am. Ent. 

 Soc. XXXVII, 207) for the species. A careful examination of the 

 specimen in question to determine the sex will be necessary to decide 

 the point; if a 9 there is no reason, as far as can be judged by the 

 figure, why it should not be referred to smithi; the increased size of 

 the spots on primaries and the presence of a distinct band of spots on 

 the secondaries are features common to the 9 's of most of the family ; 

 if a S then Skinner's name will hold. 



Habitat. Texas (Corpus Christi) (Barnes); Mexico (Amula in 

 Guerrero).

W'e know nothing of this species ; it is the southernmost member 

 of the family. Druce's figures show a very distinct species, appar- 

 ently most closely related to smithi Druce. The present position is 

 merely tentative. 



Habitat. Costa Rica (Carthago) ; Panama (Chiriqui).
