344 MR. M. JACOBY ON THE [Mar. 7, 



less testaceous. In a specimen from Abyssinia contained in 

 my collection the elytra have a satural and discoidal black longi- 

 tudinal band, the latter being interrupted anteriorly, leaving the 

 shoulder-spot isolated ; this specimen differs in no other way from 

 the type. The species seems to have a wide distribution in Africa, 

 which no doubt accounts for its many aberrations. 



Lost GIT ABSUS dimidiaticoejstis, sp. n. 



Black, shining, the head piceous, the basal and apical joints 

 of the antenna? fulvous ; thorax very minutely punctured ; elytra 

 more strongly aud closely punctate-striate, knees obscure fulvous. 



Length 4 millim. 



Of oblong, sabcylindrical shape ; the head piceous, impunctate, 

 the frontal elevations feebly raised, the clypeus with a strongly 

 raised central ridge ; eyes very large ; antennas filiform, black, the 

 lower three and the apical two joints fulvous, the third joint oae- 

 half longer than the second, thinner, the seventh and the following 

 joints more elongate ; thorax nearly twice as broad as long, the 

 sides straight, with comparatively broad flattened margins, the 

 anterior angles obliquely thickened, the surface very minutely but 

 not very closely punctured ; elytra slightly wider than the thorax, 

 subcylindrical, the apex broadly rounded, the surface distinctly 

 and closely panctate-striate ; below and the legs black, the knees 

 to a small extent fulvous, posterior femora strongly incrassate,

Hob. Cameroons {Conrad). 



Of this species, distinguished by the colour of the antennse, the 

 broad thorax and its flattened margins, I received a single specimen 

 from Dr. Kraatz. 



Aphthona duebanbnsis, sp. n. 



Subquadrate-ovate, black, the head fulvous ; thorax flavous, 

 extremely minutely punctured ; elytra very finely and closely 

 punctured, flavous, the sutui-al and lateral margins narrowly 

 piceous ; legs flavous, the posterior femora piceous above.

Head impunctate, fulvous, the eyes with a few punctures or 

 short grooves near the inner margins, frontal elevations narrowly 

 oblique, distinct, labrum piceous ; antennse rather long and slender, 

 flavous, the apical three or four joints blackish, second and third 

 joints equal, the following two more elongate, of equal length, 

 the apical joints longer ; thorax subquadrate, one-half broader than 

 long, the sides straight, the anterior angles oblique, posterior 

 angles acute, the surface flavous, shining, with a few microscopical 

 punctures ; scutellum black ; elytra wider at the base than the 

 thorax, subcylindrical, very flnely and closely punctured, the 

 punctures somewhat regularly arranged, the sutural and lateral
