CEROBATES ADUSTUS. 185 



vity, rounded at the apex; depressed above , tristriate along 

 the suture in the basal third, bistriate in the remainder 

 portion, the striae are curved, the l^t interstice is broad 

 at the base, very narrow but not interrupted towards the 

 middle , at the sides the elytra are striated. 



Legs regular. Body beneath chestnut-brown, head-, basal 

 portion of the rostrum and prosternum covered with brownish 

 yellow scales; the rostrum between the antennae has a 

 short median keel, the metasternum and the 2nd abdomi- 

 nal segment are deeply furrowed, the l^t segment is exca- 

 vated , the apical one scaled. 



Allied to the preceding species, but differing by its 

 greater size, the broader prothorax and the S^d stria (ex- 

 ternal) finishing at the basal third of the elytra. From 

 C. sexsulcatus Motsch. this species may be distinguished 

 by the shape of the Q^l^ and lO^Ji joints of the antennae, by 

 the elytra being striate at the sides , and by its greater 

 size and different colour. 



Taphrocomisteri n. g. 

 (rixCppot; = fossa , y,oiAi7TVjp = lator). 



A genere Higonio Lew. dififert prothorace antice latiore , 

 lateribus postice minus arcuatis; elytrorum declivitate api- 

 cali depressione circulari , excavata , intus granulata , mar- 

 ginibus prolatis , integris instructa. 



This genus is allied to Iligomus Lew., but differs by the 

 prothorax being broader at the apex and less curved at 

 the sides posteriorly, and by the apical declivity which is not 

 obliquely sloping but truncate, showing a circular, concave 

 depression with a projecting margin. This conformation 

 of the apex of the elytra , nearly like that of some Pla- 

 typidae, is an abnormal character in the Brenthidae , and 

 I believe it sufficient to base a new genus upon it.
