apex in the apical half. Antennae with the club very long and finely, aspe- 

 rately punctate throughout. Prosternal process moderate in width, the apex 

 inliexed and unarmed ; metasternal process rather wide, with the sides parallel, 

 rather long, extending fully to the anterior limits of the coxse, broadly, evenly 

 rounded at apex. Mesosternum in front of the metasternal process forming a 

 very thick, strongly prominent, feebly scabrous and minutely setose marginal 

 bead, which becomes fine along the inner side of the coxae, and is dilated 

 behind the middle acetabula as in Acylomus. Legs slender ; posterior tarsi 

 very slender, cylindrical, nearly as in Litochrus, but with the first joint 

 scarcely four-fifths as long as the entire remainder ; posterior tibial spurs 

 moderate, very slender, decidedly unequal. 



In the structure of the ligula, labial palpi, and the extension of 

 the mesosternum behind the middle acetabula, this genus difl'ers 

 very greatly from those species which we consider Litochrus and 

 represented hj pulchellus as a type; the basal joint of the posterior 

 tarsi is also distinctly shorter, and the third joint of the latter is 

 very obliquely truncate at apex, the fourth with its ill-defined basal 

 lobe being inserted at the middle of the truncation. 



Ij. scalptus n. sp. — Rather broadly oval, piceous-black throughout 

 above ; under surface, legs and antennae very pale flavate ; polished. Head 

 finely, sparsely but rather distinctly punctate ; eyes unusually small ; antennae 

 robust, the club almost as long as the entire remainder, third joint fully as 

 long as the next two together, outer joints of funicle robust and transverse, 

 ninth and tenth subequal in length, eleventh as long as the two preceding. 

 Prothorax very feebly, sparsely and obsoletely punctate, polished ; basal lobe 

 as in Litochrus but more feeble ; marginal bead obsolete. Scutellum ogival, 

 nearly twice as wide as long. Elytra entirely polished, without trace of fine 

 sculpture, having series of long fine transverse scratches, the punctures 

 entirely obsolete, although each of the fine lines has a very minute recumbent 

 hair in the middle, the lines feebler toward base and apex, the series so close 

 that the transverse lines are sometimes continuous laterally ; sutural bead 

 subapical, excessively fine ; discal striae obsolete at basal third, distinct, the 

 first continuous to the apex, the second coincident with the first at apical 

 fourth. Abdomen finely, feebly reticulate, sparsely, coarsely pubescent. Legs 

 moderate in length. Length 1.5-1.7 mm.

The posterior tibiae, in the males, are slightly more robust than 

 in the females, but there does not seem to be any decided sexual 

 difference in the terminal spurs or tarsi. 



The remarkable transverse scratches, which are an extreme modi- 

 fication of the ordinary type of transversely crescentic punctures, 

 are peculiar to Litochropus and Ochrolitus, and it is probable that 

 Litochrus globulus Sharp, should be assigned to the present genus.
