14 Mr. F. P. Pascoe on some new or little-hnown 



one at the base, the first stria much deeper than the others; body 

 beneath chestnut, finely and remotely, the mesosternum and last four 

 abdominal segments coarsely pimctured; legs stout; tibiae short, all 

 strongly spurred, the anterior and intermediate pairs trigonate, dilated 

 and toothed externally ; tarsi nearly as long as their corresponding 

 tibiae. Length 3 lines. 



This species is also referred doubtfully to Bothrideres, principally 

 on account of the large terminal joint of the club, and the short and 

 unusually trigonate tibiae ; these characters are, however, chiefly ones 

 of degree, and not of plan. An examination of the trophi (which, 

 as the specimen is unique, I have not attempted) might probably 

 afford stronger grounds for its generic separation. 



Machlotes [Colydiidae]. 



Caput receptum, triangulare, sulcis antennariis. Antenncs breves, articulo 

 prime incrassato, libero, clava biarticulata. ProtJiorax sulcatus, postice 

 trans versim fissus. Elytra ovata, costata. Pedes robusti ; jn'otibns sub- 

 trigonatis, anterioribus spina terminali ; tarsis brevibus. 



A very distinct genus, although, from its widely separated coxae 

 and large basal segment of the abdomen, allied to Bothrideres. The 

 sculpture of the prothorax is, however, peculiar, owing to the pre- 

 sence of a deep transverse cleft posteriorly, dividing, and even dipping 

 below the longitudinal grooves by which the disk is indented. I 

 regret that, having only a single specimen, for which I am indebted 

 to Mr. Bowring, I cannot throw any light on the structure of its 

 mouth, which might perhaps have afl'orded some clue to its affinities ; 

 but if it has no connexion with Dastarcus — and even in that case it 

 cannot be a near one — it must remain for the time an isolated genus 

 among the Bothriderince as they have been defined by Erichson.

Hab. Penang. 



Dark brown, opake, the antennae and legs subrufous ; head inserted 

 to the eyes in the prothorax, small, and coarsely punctured ; antennae 

 not longer than the breadth of the head, imcovered at their insertion, 

 the basal joint very thick, the remainder more or less transverse, the 

 tenth and eleventh forming a short circular club, of which the last joint 

 is much the smallest ; antennary grooves well marked ; eyes round ; 

 prothorax about half as long again as broad, narrowed behind, truncate 

 and a little gibbous in front, slightly rounded at the sides, the anterior 

 angles prominent, — the disk with three very strong costae on each side,
