172 NEUROPTERA. 
1. Epigomphus camelus, sp. n. (Tab. VIII. figg. 1-3.) 
Description, page 170. 
Hab. Costa Rica, Carrillo (Underwood: 1 ¢). 
The specific name is an allusion to the “two-humped ” tubercle on the dorsum of 
the tenth abdominal segment. 
2, Epigomphus quadracies. (Tab. VII. fig. 36; Tab. VIL. figs. 4, 5.) 
Epigomphus quadracies, Calvert, Ent. News, xiv. pp. 188-191 (1903) 
~ Hab. Guaremata, San Isidro (Champion: 1 31); Panama, Chiriqui! (coll. McLachlan : 
1 3 with label “ Ep. subodtusus, S.,” in Selys’s hand, 1 @ abd. segs. 5-10 lost). 
It is rather surprising that de Selys should have so identified the Chiriqui male, as 
the differences in the appendages are very considerable.

Epigomphus tumefactus, Calvert, Ent. News, xiv. pp. 188, 190, 191, t. 8. fig. 4 (venation, outline 
of body) (1908) ’.
