Elijlni liiit little liruiidor tliaii tliorax, their inarf^in.s soiiKnvhat i'X])luiiutt'. 

 eiich witli a iitw of well-marked punctures ; their whole surface very dis- 

 tinctly l»ut irregularly punctured, the intervals smooth and shiniiiL'. 



Wo possess no other described species like this. The peculiar form of 

 thorax and the conspicuous elytra! sculptun^ suffice for immediate ideiititica- 

 tion.

Mount Arthur. One example amon;.;st a miscellaneous collection 

 made by Mr. T. F. Cheeseman, and the late Mr. .1. Adams, then headmaster 

 of the Thames Ili^h School, whose los.s as a j^enial friend I sincerely de])Iore. 



."iOTu. Asilis brevicornis sp. nov. 



Nitid, nearly nude, black, antennae and le^s fuscous, mandibles and 

 claws fulvescent. ' 



Head rather narrower than front of thorax, opaque, seemingly without 

 sculpture. Antmnne rather short, extending but little beyond the base 

 of elytra, their 2nd and 3rd joints of equal leufith. Thorax transverse, 

 apex sli«fhtly rounded, its sides nearly straight, with simple margins, which, 

 however, are moderately incrassate in front, but not forming definite 

 anterior angles ; basal margin moderately rounded, and uniting with those 

 along tlie sides without forming sharp angles ; disc moderatelv convex, 

 with a longitudinal impression on the middle, it seems to be impunctate 

 but near the sides has minute close sculpture, the basal and frontal series 

 of punctures are moderately distinct. Elytra as wide as thorax at the base, 

 a little dilated behind the middle, their piuutation moderately close and 

 distinct, rather shallow and less evident near the shoulders and apices. 



DilTerentiated by the aljbreviated antennae ; their 2nd and 3rd articu- 

 lations are rather longer than the corresponding ones of .1. /KiiallilHs. but 

 the succeeding ones are shorter.

307G. Asilis opaculus sp. nov. 



Depressed, elongate, yet rather broad, subparidlel ; pubescence close, 

 decumbent, slender, and ash-coloured ; bodv black, thorax shining, elytra 

 opaque ; the antennae, palpi, and legs niuro-fuscous. mandibles and claws 

 castaneous. 



Head half the width of thorax, with 2 shallow interocular foveae, modi-- 

 rately clo.sely and finely punctured, only slightly nitid. Thorax transverse, 

 apex rounded, with elevated margins and obsolete angles ; its sides 

 moderately curved, with thick retlexed margins which are rather broad at 

 the middle ; po.sterior angles rectangular Itul not acute, formed by the 

 union of the basal and lateral margins, the base ol)lique towards the sides ; 

 disc uneven, with a median antebasal impression. 2 obtuse elevations, and 

 ft transverse basal depression between the middle and each side, the surface 

 finely and moderately closely jninctured, and with some larger but not coarse 

 punctures near the basal and frontal margins. Sculrlluni not smooth. 

 Elytra a little broader than thorax, obtusely rounded behind, with dense, 

 slightly rugose, granular s( iilpture. which, however, is rather less distinct 

 near the shoulders. 



When coiupared with .1. i/nifiiprnnis this speiies mav be recognised by 

 the much more granular and denser elvtral .sculpture and oj)aque surface, the 

 thorax is dilTerently sculptured and glos.sy instead of lieing dull, and the
