344 MR. M. JA.COBT ON THE [Mar. 7, 



less testaceous. In a specimen from Abyssinia contained in 

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

 tudinal band, the latter being interrupted anteriorlv, 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. 



LONGITABSUS DIMIDIATICOEjN^ IS , sp. n. 



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

 of the antennae fulvous ; thorax very minutely punctured ; elytra 

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



Length 4 millim. 



Of oblong, subcylindrical shape; the head piceous, irapunctate, 

 the frontal elevations feebly raised, the clypeus with a strongly 

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

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

 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 shghtly wider than the thorax, 

 subcylindrical, the apex broadly rounded, the surface distinctly 

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

 to a small extent fulvous, posterior femora strongly incrassate, 

 their tibife greatly widened near the apex, and sulcate, the first 

 joint of the posterior tarsi much longer than the following joints 

 together ; prosternum very narrow. 



Hah. Cameroons {Conrad). 



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

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

 from Dr. Kraatz. 



ApHTHOXA DUEBAIfElfSIS, Sp. n. 



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

 extremely minutely punctured ; elytra very finely and closely 

 punctured, flavous, the suturai and lateral margins narrowly 

 piceous ; legs flavous, the posterior femora piceous above. 



Length 3 millim. 



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

 short grooves near the inner margins, frontal elevations narrowly 

 oblique, distinct, labrum piceous ; antennae 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 finely and closely punctured, the 

 punctures somewhat regularly arranged, the suturai and lateral 

 margins narrowly piceous, this colour not extending in either case
