Two specimens in the British Museum have been sent by 

 Professor R. Thaxter. 



The striking pattern upon the elytra, consisting of five 

 large round black spots placed in a circle upon their basal 

 part, together with the black femora and til)ise and ))ale 

 tarsi, render this species very easy of recognition. The 

 second, and smaller, specimen is without the spots ; but 

 this is apparently owing to immaturity, -the red ground- 

 colour being paler. The eyes are very large and pro- 

 minent, the diameter of each scarcely less than that of 

 the space between them. The club of the antenna is 

 long, narrow, and loosely articulated, the last joint small 

 and globular and the two preceding ones triangular. 



Amblyopus lateralis, sp. n. 



Niger, elytris, abdomine, tarsis, antennarumque apicibus rufo- 

 fulvis, elytris extus nigro-cinctis, margine aiitica pono scutellum 

 triaugulariter dilatata ; elongatus, angustus, oculis magnis, 

 grosse granulatis ; pronoto undique subtiliter punctate, lateribus 

 fere rectis, aiigulis omnibus paulo obtusis, basi medio leviter 

 lobato : scutello transverse pentagonali ; elytris subtiliter punc- 

 tato-striatis, intervallis subtilissime punctulatis ; pedibus sat 

 longis, tibiis ad extremitates modice dilatatis ; autennarum 

 articulis 3-8 plus minusve elongatis, 9-11 transversis, laxe 

 articulatis. 



Long. 7-8"5 mm. ; lat. max. 3'5-4 mm. 



Uganda : Entebbe (C. C. Gowdey^ May). 



The coloration of this species also is quite distinctive and 

 peculiar', the elytra, abdomen, and tarsi being orange-yellow, 

 the elytra completely encircled with black, which embraces 

 the scutellum and extends behind it a short distance down 

 the suture. It is of similar size to A. /nilchellus, but less 

 convex and rather more finely punctured, with the elytra 

 more elongate, more straight-sided and tapering. The 

 legs are a little longer and the antennae rather more slender. 

 The prosternum is triangular, broad and slightly emarginate 

 behind, and the mesosterutim is almost square. 



Amblyopus tristis, sp. n. 



Kigro-piceus, clypeo, scutello, corporeque stibtus rufo-piceis, 

 pedibus at anteunis laete rufis ; modice elongatus, parura 

 nitidus, capite leviter punctate, oculis maguis, grosse granu- 

 latis ; pronoto minute sat crebre punctato, lateribus leviter 

 arcuatis ; scutello lato, punctttlato ; elytris fortiter punctato-
