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 tibiz and pale 
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 jomt small 
and globular and the two preceding ones triangular. 
Amblyopus lateralis, sp. n. 
Niger, elytris, abdominoe, tarsis, antennarumque apicibus rufo- 
fulvis, elytris extus nigro-cinctis, margine antica pone scutellum 
triangulariter dilatata; elongatus, angustus, oculis magnis, 
grosse granulatis ; pronoto undique subtiliter punctato, lateribus 
fere rectis, angulis 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; antennarum 
articulis 3-8 plus minusve elongatis, 9-11 transversis, laxe 
articulatis. : 
Long. 7-8°5 mm.; lat. max. 3°5-4 mm. 
Ucanpa: 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. pulchellus, 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 antenne rather more slender. 
The prosternum is triangular, broad and slightly emarginate 
behind, and the mesosternum is almost square. 
Amblyopus tristis, sp. 0. 
Nigro-piceus, clypeo, scutello, corporeque subtus rufo-piccis, 
pedibus et antennis lete rufis; modice elongatus, parum 
nitidus, capite leviter punctato, oculis magnis, grosse granu- 
latis; pronoto minute sat crebre punctato, lateribus leviter 
arcuatis; scutello lato, punctulato; elytris fortiter punctato-
