1048 COLEOPTERA 



moderately short and stout, pubescent ; second articulation nearly 

 as long as the exposed portion of the basal one ; third rather 

 longer than fourth, both of which are narrowed towards the base ; 

 fifth distinctly broader but not longer than third, not symmetrical, 

 being a little cut away towards one side ; joints 6-8 broader than 

 the preceding ones, transverse, united together by narrow central 

 stalks, so that evident gaps exist between the wider parts ; ninth 

 largest, oblong, with a median cavity near the front ; tenth half the 

 bulk of the penultimate, obtusely produced, the two last-mentioned 

 punctate. Thorax smooth, widest before the middle. Elytra large, 

 widest behind, sutural grooves deeply impressed. Hind-body smooth, 

 very sparingly and indistinctly clothed, nearly vertical. Legs stout ; 

 anterior tibiae medially incrassate ; intermediate gradually dilated, 

 but tapered off near the extremity ; posterior bicurvate, inwardly 

 nearly the base and outwardly beyond. 



The laxly-articulated sixth, seventh, and eighth antennal joints, 

 and the presence of four frontal foveae, will lead to the recognition 

 of this species. The former character is not, I find, confined to this 

 species. Its nearest allies are B. impar and B. munda. The 

 structure of the underside I have been unable to examine.

Antenna rectae, undecimarticulatse. Palpi maxillares breves, 

 sirnplices, articulo ultimo ovale. Caput superne subproductum, 

 supra antennas fortiter tuberculato-elevatum, his sat approximatis. 

 Tarsi unguiculo uiiico. Abdomen e segmentis ventralibus sex, dor- 

 salibus quinque, compositum. 



The insect for which I establish this genus is not at all closely 

 allied to any other European or exotic form known to me. It has 

 the aspect of a Batrisus, but in Eeitter's arrangement of the family 

 would apparently be placed in the Pselaphini. The first ventral seg- 

 ment behind the coxae is quite short, and is strongly carinate-elevafe 

 between the coxae which are approximate ; the following segments are 

 short, the second being, however, as long as the third and fourth 

 together, the fifth short and transverse ; the sixth in the male (from 

 which this description is taken) is large at the side, but in the middle 

 is cut away nearly to the base. The first visible dorsal segment is 

 rather short, but longer than the second ; this, as well as the third 

 and fourth, are subequal, the apex much deflexed, the two or three 

 basal segments obscurely margined at the sides, with greater in- 

 equality in the lengths of the segments. The palpi are similar to 

 those of Batrisus. .The front coxa are exserted, and rather elongate. 

 The tarsi consisting apparently of two elongate joints, but there is 

 also really a minute basal joint ; the single claw is elongate.
