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 Carchariacephalus 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. 



Carchariacephalus smithii n. sp. Length: 9, 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
