being conspicuously wider at apex than elsewhere. This dif- 

 ference appears very slight to found a genus upon ; never- 

 theless the four species are so obviously closely related, and 

 in facies and clothing certainly different, to Tyrtceosus, that 

 it does not appear to be desirable to refer them to that genus. 

 The second abdominal segment slopes down at an angle of 

 45° ; in most species of Tyrtceosus the descent is more gradual;, 

 the species of that genus usually also have decidedly shorter 

 legs.

Tyrt^osellus coxalis, n. sp. 

 (S . Black, antennae and tarsi reddish, elytra partly^ 

 reddish. Moderately clothed with sooty scales, with three 

 vague lines of paler ones on prothorax, and a wide, somewhat 

 irregular, sutural one on elytra; with stout scales inter- 

 spersed, and on the elytra more or less upright. Under- 

 surface of body and of legs mostly with whitish clothing. 



Head with dense, normally concealed punctures. Rostrum 

 almost parallel-sided, almost as long as prothorax; basal half 

 with coarse concealed punctures, elsewhere with smaller but 

 fairly dense and clearly-defined ones. Antennae inserted one- 

 third from apex of rostrum. Prothorax feebly transverse, 

 sides strongly rounded, apex about half the width of middle; 

 with dense, round, partially-concealed punctures; with a 

 short and feeble median carina. Elytra elongate-subcordate, 

 parallel-sided to middle; with rows of large, partially- 

 concealed punctures, becoming smaller posteriorly. Under- 

 surface with rather dense and large punctures. Femora 

 lightly but distinctly dentate, hind pair extending to apex 

 of elytra ; hind coxae each with a whitish fascicle. Length,. 

 2f-3| mm. 



9 • Differs in having the rostrum slightly longer and 

 thinner, with smaller and sparser punctures, concealed only 

 at extreme base, antennae inserted not quite so close to apex 

 of rostrum, and hind coxae not fasciculate.

The elytra are reddish along the middle, except about 

 base, for a space of two or three interstices on each side of 

 suture, the parts there usually being covered with pale scales,.
