182 Mr. A. Sidney Olliff's remarks on a small 



Inopeplus, Smith. 



Inopeplus borneensis, n. s. 



Black, shining. Head twice as broad as long, dis- 

 tinctly and closely punctured, with a well-marked longi- 

 tudinal impressed mesial line in front. Antennae with 

 the two basal joints pitchy. Prothorax in front broader 

 than long, strongly and obliquely narrowed behind, dis- 

 tinctly and rather closely punctured, anterior margin 

 slightly produced in the centre, sides gently rounded in 

 front. Scutellum transverse, rounded behind. Elytra 

 piceous, with a brassy tint, as long as the head and 

 prothorax together, at the base not quite as broad as the 

 prothorax, much broader behind, rather coarsely and 

 moderately closely punctured, humeral angles obtuse, 

 sides very finely margined ; apex of each elytron arcuate. 

 Abdominal segments finely and irregularly punctured, 

 sides regularly rounded. Legs pitchy, tarsi paler. 

 Length, 3£ mm. ; width of abdomen, If mm. 



In the form of the head and prothorax this species 

 agrees best with Inopeplus terminates, Waterh. (Ann. 

 Mag. Nat. Hist. (5), iii., p. 214), and in the shape of the 

 elytra and abdomen with I. ephippiatus, Pascoe. It is, 

 however, at once distinguished from either of these 

 species by its unicolorous elytra and less strongly punc- 

 tured head. 



Platycotylus, n. g. 



Head transverse. Eyes large, lateral, the greater 

 portion being visible from above. Antennae 11 -jointed, 

 flattened, gradually thickening towards the apex, basal 

 joint short, 2nd rather shorter and narrower, 3rd a little 

 longer than the 1st and thickening towards the apex, 

 4th to 7th equal in length and somewhat shorter than 

 the 3rd, 8th to 10th shorter and rather broader, apical 

 considerably longer and rounded at the apex. Mandibles 

 short, robust, and simple, with the inner margin slightly 

 sinuate before the apex. Maxillae with the inner lobe 

 small, narrow, and rather finely pointed ; outer lobe 

 nearly twice as long as the inner, much broader at the 

 apex than at the base ; inner margins of both lobes 

 clothed with long bristly hairs. Maxillary palpi 4- 

 jointed, basal joint short and narrow, 2nd much longer 

 and broader at the apex than at the base, 3rd narrower
