elytra parallel, obtusely rounded behind, the humeri widely exposed at 

 base, the sides nearly straight, the humeral angles well rounded, distinctly 

 more than twice as long as wide. Length, 5.8-6.5 mm.: width, 1.6-1.8 

 mm.

 * The sexual characters of the male are not observable m any of the 

 specimens before me. In well preserved individuals there is a feeble 

 maculation of small spots, in which the vestiture is still denser, but of the 

 same character ; on the elytra'these small rounded spots are remotely 

 spaced in rather regular series. 



LiOB.\ULius, n. gen. — Anlhicidte. 



Body small in size, convex, with narrow head and prothorax and 

 inflated hind body, the elytra largely smooth, punctureless and polished, 

 with a strong transverse opaque impression near the base ; head with the 

 eyes well developed and noticeably before the middle, semicircularly 

 rounded at base, the neck very narrow ; last joint of the maxillary 

 paljji moderate in size, very obliquely securiform ; antenncC slender, more 

 or less strongly and gradually incrassate distally ; prothorax very convex, 

 circularly rounded at the sides, constricted between basal third and 

 fourth, the constriction confined to the sides ; basal part feebly expanding 

 to the base and much narrower than the rounded anterior part ; apical 

 collar well developed, much wider than the neck ; elytra strongly convex 

 behind the subbasal pubescent impression ; legs moderately long, slender, 

 the basal joint of the hind tarsi as long as the remainder, the penultimate 

 joint slightly dilated, strongly lobed, deeply grooved above and angularly 

 marginate at tip, the last joint inserted near its base ; mesosternum 

 expanded greatly toward the sides of the body, forming a broad polished 

 and wholly sculptureless plate, rounded and fimbriate at the sides, the 

 seti\i sparse, the plate with a beaded edge throughout ; epiniera, at the 

 sides, and episterna in front of the polished plate, both very narrow and 

 dull in lustre, finely sculptured ; anterior coxal cavities open behind. 



As may be inferred from these characters, this genus is allied to 

 Baulius, but differs wholly in the general facies and sculpture of the body, 

 form of the head and absence of the fringe of setae at the sides of the 

 exi)anded mesosternal plate ; it also differs in having a few series of 

 rather long, very sparse stiff setoe on the elytra, ihese being wholly 

 wanting in Baulius. The species known to me, which will include also 

 the Anthicus dromedarius of Laferte', may be described as follows ;
