EPOMIDIOPTERON. 



Epomidiopteron, de Romand, Ann. Soc. Ent. Fr. 1835, p. 653 ; Sanssure & Sichel, Cat. Sp. Gen.

This is a genus of small extent, and purely a neotropical one.

Head coarsely punctured, densely covered with long fulvous hair ; the clypeus finely 

 punctured and covered with fulvous hair ; the mandibles reddish in the middle. The 

 scape of the antenna? strongly punctured, bearing long fulvous hair, and rufous at the 

 apex ; the flagellum thick, covered with a fulvous pubescence. The pro- and mesothorax 

 densely covered with fulvous hair. The pronotum apparently punctured, but the punc- 

 tuation cannot be well seen from the thick hair covering it ; the propleurse striolate 

 throughout; the mesonotum with large, widely separated punctures; the lateral 

 depression wide and deep ; the scutellum and postscutellum punctured ; the median 

 segment in the centre coarsely shagreened, the sides irregularly reticulate, the central 

 keel straight, the lateral keels oblique, becoming united at the apex to the central one. 

 The mesopleurse are coarsely punctured ; the metapleurae striolate. The abdomen is 

 closely punctured throughout ; the segments at the apex thickly fringed with golden hair ; 

 the pygidium closely punctured, reddish, the base covered thickly with long fulvous hair. 

 The legs thickly covered with silvery hair, the hair on the outer side of the hind tibiae 

 golden ; the apices of the tarsi rufous, the calcaria white. The third cubital cellule is 

 longer than the first and second cellules united ; the first recurrent nervure is received 

 about the same distance from the base that the second is from the apex of the cellule. 

 Tegulse large, dull rufous. 



This species is evidently very near the preceding, but differs from it in having the 

 tegulee large, and the third cubital cellule longer than the first and second cellules 

 united (in E. sumichrasti it is apparently only the length of the second). The relative 

 lengths of the cellules are not mentioned by Sichel ; but from his remarks (Cat. Spec. 

 Gen. Scolia, p. 264) I conclude that his figure (t. 1. fig. 8) of the wing is applicable to 

 E.julii and E. sumichrasti, in which case the neuration is different from that of our 

 species. Sichel {op. cit. p. 269) suggests that E. sumichrasti should form the type of a 

 new genus or subgenus, for which he proposes the name Paratiphia. Not having an
