being considerably tectiform. The male genitalia are very dif- 
ferent from those of other families, but the nature of the aedea- 
gus places it in the Cixiine group, although otherwise it might 
be placed near the Achilidae in the Meenopline group. 
The male pygofer is normal, with a transverse bar across the 
middle to which the base of the aedeagus is attached (fig. 5, 
t. b.) ; the aedeagus shows no sign of division into periandrium 
and penis, but is cultrate, the ventral margin being double and 
curved, the dorsal margin straight and single. The ovipositor is 
incomplete. 5 
The family is erected for a single genus containing four spe- 
cies. I hesitated before erecting the family, but as the genus 
cannot be placed in any recognized family without doing vio- 
lence to the family characters it is best placed by itself.* 
VII. DiIcTYOPHARIDAE. 
Dictiophoroides Spinola (1839), Ann. Soc. Ent. Fra., VIII, pp. 202, 
283; type Dictyophara Germar, Silb. Revue Ent., I, p. 175 (1833). 
This family was monographed by Melichar in 1912, at which 
time he recognized seventy-six genera. He divided it into five 
groups, which I shall consider as two subfamilies with five tribes.

Melichar called his Group IV Bursini, although he placed the 
genus Bursinia Costa in his Group V, Orgerini. The above 
classification is likely to be modified with further study. 
The tegmen has no costal area, or a very narrow one without 
transverse veins; the claval vein does not reach the apex of 
clavus. Besides the lateral margins the frons generally has two

Eeuador, representing two species of an undescribed genus which goes into 
this family. There is only one rounded process bearing three depressions.
