416 COLEOPTERA. 



Length (lostruin inclusive), 3i mm. ; breadth, U mm. 

 Mount Algidu.s, Cantorburv ; 25th September, 1913. Another unique 

 from Mr. T. Hall. 



3887. Catoptes flaviventris sp. nov. 



Opaque, without inequalities ; fuscous, rostral apex rufescent, legs and 

 antennae fusco-testaceous ; densely clothed with depressed fuscous squamae, 

 but just below the summit of the posterior declivity there is a broad band 

 of paler brown scales ; the small serial setae on the elytra are white and 

 decumbent but suberect behind. 



Rostrum subparallel, only feebly dilated in front, a third shorter than 

 thorax, not in the least depressed at the base, obsoletely carinate. Thorax 

 oviform, slightly broader than long, its sculpture invisible, with some minute 

 whitish setae on the disc. Scutellum small. Ehi:ra quite twice the length 

 of and a third broader than the thorax, incurved and distinctly bi'oader 

 than it is at the base, narrowed but not vertical behind : apparently striate- 

 punctate, with simple interstices, the suture somewhat convex behind. 



Underside fusco-testaceous, with pale scales and slender elongate setae. 

 Prosternum deeply emarginate, with contiguous coxae. Basal segment as 

 long as the metasternum, both broadly impressed along the middle, 2nd 

 rather shorter, its frontal suture sinuate, 5th as long as 3rd and 4th 

 combined, romided behind. 



This resembles C. pallidipes in structural details with the exception of 

 the ocular lobes, which are obsolete. The eyes, antennae, and legs are 

 similai'. The hind-body is more oblong and narrower, and there is no basal 

 depression of the rostrum. The only example extant has strongly developed 

 supplementary mandibles, the left being curved and acute at the extremity.

Mount Algid us. A single indi\'idual found bv Mr. T. Hall on the 25th 

 September, 1913. 



3888. Catoptes nigricans sp. nov. 



Opaque, nigrescent, antennae fusco-rufous, legs pitchy-red ; covered 

 with ashy scales nearly as dai'k as the derm, and with decumbent greyish 

 setae, these give the rostrum a speckled appearance. 



Nearly allied to C. jlavivenlris. The rostrum feebly carinate along the 

 middle. Thorax as long as broad. Scutellum small, indistinct. Elytra 

 hardly double the length of thorax, slightly broader than it is at the base, 

 distinctly substriate-punctate, interstices simple. Eyes rather smaller and 

 more distant from the thorax. 



Underside black, nitid, with white scales and elongate setae. Proster- 

 nuni moderately incurv(^d. Basal segment rather longer than metasternum, 

 depressed along the middle, 2nd flat, both distinctly punctate. 



o. Length (rostrum inclusive), 3J mm. ; breadth, li mm. 



Scarclift": 19t]i October, 1913. Two from Mr. Hall, one damaged. 



3889. Brachyolus bicostatus sp. nov. Brachi/olu,s White, Man. X.Z. 



Cleopt.. p. 1191. 



Elongate, convex, opaque, piceous, antennae and tarsi fusco-rufous ; 

 covered with depressed, infuscate-tawny scales, and coarse, decumbent, 

 greyish setae, those on the legs erect.
