Figures 60, 61 



Omphrale fraterna Krober, 1923, p. 81. 



Krober remarks on the similarity of the male of this species with 

 that of S. nitidulus. Certainly in the details of the head, wing and 

 external genitalia they agree in most respects. The principal difference 

 lies in the internal genital structures where a marked difference in 

 the size of the ejaculatory pump is evident. 



Figure 60. — Scenopinus fraternus (Krober), male: a, wing; h, c, lateral and frontal aspects 

 of head; d, enlarged detail of antenna; e-g, ventral, lateral and posterior aspects of 

 terminalia. 



There is some doubt, however, as to whether the female is of the 

 same species as the male. The wings do not agree at all well in the 

 two specimens ; see figures.
