392 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93 



Type locality. — El Quemado, Jujuy, Argentina (G. L. Harring- 

 ton). 



Allotype, female (U.S.N.M.), same data as type. Identical with 

 type except for color and antennal structure. The antennae have 

 the first and second joints as in the male, joint 3 three times as 

 long as 2, as broad at its base as apex of joint 2, thence expanded to 

 about twice its basal diameter. Joint 4 is about as long as 3, broaden- 

 ing toward its apex, which ends in a small nipplelike elevation. In 

 figure 12, c, the third antennal is considerably foreshortened. The 

 color of the allotype is darker and more uniform than that of the 

 type, and the sutural stripe is scarcely evident. I am inclined to 

 think that all the specimens are teneral and that the allotype more 

 nearly represents the mature condition. Besides the type and allo- 

 type the U. S. National Museum collection contains an imperfect 

 male paratype, and there is a male paratype in the author's col- 

 lection; data same as for type. 



Figure 12, d, e, was made from a specimen of Epopterus from Peru. 

 Although it lacks the pronotal spots I consider it an individual of 

 E. decoratvs Kirsch.
