pressed along sides; upper surface punctate; anterior angles 

 rounded, not marked; base truncate above peduncle, sinuate on 

 each side. Elytra truncate-oval (5x3-7 mm.), rounded on sides, 

 and on each side of base : external apical angle not marked; 

 apical truncature obliquely sinuate on each side, rounded at apex 

 of three inner striae, triangularly excised at suture; striae strongly 

 impressed, interstices lightly convex, strongly punctate; third 

 with three dorsal punctures, and one at apex; eighth interstice 

 wider than seventh and ninth, closely punctate (the punctures 

 in about four irregular rows); ninth interstice narrow, finely 

 punctate, with a row of widely placed larger punctures; marginal 

 channel punctate; inllexed margin punctate. Prosternum punc- 

 tate ; metepisterna quadrate, punctate. Anterior tarsi in ^ 

 nariow; three basal joints biseriately squamulose in middle of 

 under side. Apical ventral segment unisetose on each side of 

 apex. Length, 9-10; breadth, 3-5-3-7 mm. 



Hab.—W.A.: Cue (H. W. Brown). Type in Coll. Sloane, 

 A very distinct species, differing from the otliers known to 

 me by its large size; long, narrow head and prothorax; wide, 

 oval elytra, with strongly punctate interstices. It is evidently 

 an apterous species, with the elytra soldered together; in com- 

 parison with JV. chaudoiri SI., the lateral palps are much less 

 widely securiform. 



Physoderides* 

 Lachnoderma foveolatum, n.sp. 



Oval; elytra rugose-foveolate. Head, prothorax, and under- 

 surface red; elytra blue-black; legs and antennae, after third 

 joint, black. 



Head convex, setiferous between eyes; clypeus with a setiferous 

 fovea on each side near anterior angle, a few setiferous punctures 

 on each side behind these clypeal foveae; eyes prominent; labrum 

 bifoveate, setose in foveas. Antennae, after third joint, pubescent; 

 three basal joints sparsely setiferous (about three long setae on 



* Lachnoderma has been referred to a group, Physoderides, by Bates, 

 when referring Asiatic species to the genus. I do not know the true 

 position or value of this group.
