punctate spaces. In the present species, the surface in front 

 of the foveae, although convex, does not appear to be ridged, 

 and the notch (when viewed from behind) appears to be be- 

 hind the punctate spaces. The excavated parts at the apex 

 are also not quite the same, although partly obscured by 

 clothing in both species. 



Batrisodes macrocephalus, n.sp. 



O*. Dark castaneous, appendages somewhat paler. With 

 comparatively short, depressed clothing. 



Head large, strongly convex; with a large, deep, irregular 

 fovea close to base on each side of middle ; densely and coarsely 

 punctate. Antennae, for the genus, not very thin, ninth and 

 tenth joints each about as long as wide. Prothorax moderately 

 transverse, about as wide as head across eyes; apex narrow, 

 then sides strongly rounded to middle, and thence (commenc- 

 ing at a small spine) strongly coarctate to base, two narrow 

 carinae marking off a very narrow median line, which com- 

 mences in a subbasal fovea ; sides irregularly foveate ; between 

 middle and each side with two narrow carinae, commencing 

 near the base (where they are conjoined) in a small but very 

 acute tubercle or spine; witli distinct pvuictures. Elytra con- 

 vex, about as long as wide, shoulders oblique, and each with 

 a feeble tubercle, dorsal striae traceable only at about basal 

 fourth ; with fairly numerous, clearly defined punctures. 

 Abdomen with rather small but distinct punctures, base of 

 upper surface with Ihe lateral impressions wide, and the 

 median very small ; under-surface feebly concave along middle, 

 the apical segment with a wide shallow impression. Legs not 

 very thin ; four front tibiae thickened about middle ; the hind 

 pair longest, somewhat curved, and thickened towards apex; 

 middle trochanters each with a small acute tooth, the hind 

 ones each with a small strongly curved tooth. Length 14-2 

 mm. 



9 . Differs in having the head smaller and less convex, the 

 fovepe much smaller and disconnected, the shoulders less promi-
