A REMARKABLE NEW ACOCEPHALID FROM S. AMERICA. 



By Carl F. Baker. 



In the Herbert H. Smith collection of South American Jassidae 

 there are several specimens of a remarkable Acocephalid. which 

 I refer to the genus Carchariacephahis Montrouzier, Ann. Soc. 

 Ent. Fr., 1861. p. 71. The occurrence of this genus in South 

 America is of extreme interest, the only other species being C. 

 forestieri Montrouzier, described from Lifra. The insect I de- 

 scribe as C. smithii differs from Carchariacephalus as originally 

 characterized only in a few minor points, agreeing with it in most 

 of the important particulars; it is the nearest relative of C. fores- 

 tieri among the known Acocephalini. This genus may be readily 

 separated from all other Acocephalid genera by the following 

 characters: Vertex much longer than width between eyes: face 

 very short below, clypeus reaching considerably above level of 

 eyes; head and pronotum inclined forward. 



Garchariacephalns smitMi n. sp. Length: $, 5.5 mm.; J, 5 mm. — 

 Black; antennae pale straw color, as are also legs, meso- and metasterna, 

 usually a common commissural spot at apex of clavi, and an elongate 

 triangular costal spot interrupted at apical third, averaging half the width
