inner spurs with a deep incision between, apical part not com- 

 pressed, and outer part ending in a short blunted spur, with two 

 faintly defined denticulations above it. 



Eeicheia Promontorii. 



Eeddish brown, shining ; head with a deep lateral impression and 

 a high ridge surmounted by a long seta reaching from near the neck 

 to the point of insertion of the antennae and overhanging the eye, 

 which is extremely small and quite rudimentary ; ante-ocular lamina 

 small, rounded, not incised at the junction with the epistoma, the 

 epistoma truncate ; labrum very slightly emarginate and w^ith five 

 punctures bearing a long seta; last joints of maxillary and labial 

 palpi fusiform, much swollen at the base ; prothorax very convex, 

 truncate at the apex, rounded laterally from the anterior to the 

 posterior angle, smooth on the disk and with the median line well 

 defined ; elytra ovate, truncate at the base, with the shoulders much 

 rounded, very convex, and with series of moderately deep discoidal 

 punctures disappearing past the median part of the elytra, the 

 intervals are smooth, but what should be the eighth one is more 

 distinct in the anterior part, the outer margin has a series of long 

 setae ; anterior tibiae blunted at the tip and with a short spine on 

 the outer edge with two faint denticulations above it ; intermediate 

 tibiae with a very short, outward spur. Length 2 mm. ; width f mm. 



Although the place where the eye should be is occupied by a 

 broad ridge, the two long setae found on the Clivinidae, close to and 

 also at the hind part of the eye are present also in B. Promontorii. 

 The demeanour of this species in captivity leaves no doubt at it 

 being a blind one.

 and with a bifid median tooth ; ligula horny, elongato-quadi'ate, no 

 paraglossae ; mandibles hooked ; basal joint of antennge long ; head, 

 prothorax, and elytra quite plane ; the posterior part of the body 

 pedunculate ; legs non-fossorial ; eyes with two supra-orbital setas ;
