ADELORHAGUS.— AKKHIPIS. 255 



Arrhipis, it differs in its longer and more slender antennae and by the triangularly 

 prolonged last ventral segment. The hind angles of the thorax are well carinate, as in 

 Entomophthalmus meocicanus. 



1. Adelorhagus lateralis. (Tab. x. fig. 24.) 



Oblong, subcylindrical, gradually narrowed behind from the base of the thorax, pale ferruginous, the sides of 

 the elytra and sometimes the suture fuscous, subopaque, sparsely pubescent ; antennae piceous, the last 

 joint yellowish : head closely, rather coarsely punctured, a triangular depression anteriorly with the base 

 towards the clypeus ; thorax as broad as long, sides straight and parallel at the middle, arcuately narrowed 

 in front, slightly divergent at the hind angles, which are strongly carinate, disc convex, median line 

 vaguely depressed nearly three-fourths to the apex, surface closely subgranulate ; elytra striate, striae 

 rather coarsely punctate, intervals narrow, punctate, at the sides more coarsely than on the disc ; beneath 

 much paler than above, sparsely pubescent, coarsely punctate, abdomen coarsely punctate at the sides, 

 very finely at the middle ; legs pale yellow. 



Length 4 millim. 



Hah. Panama, Bugaba, Volcan de Chiriqui (Champion). 



The fuscous border of the elytra begins at the humerus, but does not reach the tip ; 

 the suture is not so distinctly darkened. Three specimens representing the two sexes 

 are before me ; that supposed to be the female has slightly shorter antennae, and the 

 disc of the last ventral segment more convex. 



ARKHIPIS. 



Arrhipis, de Bonvouloir, Mon. des Eucndmides, p. 627 (1870). 



This genus is closely related to Microrhagus, but has no well-defined depression for 

 the antennae along the inner side of the propleurae. The two species heretofore 

 known from Mexico and the Antilles have the prosternal sutures entirely obliterated ; 

 a third, from the island of Kaioa, north of Batchian, has well-marked sutures.

Castelnau 3 gave Senegal as the locality for his E. senegalensis, but this was, no 

 doubt, in error.
