250 Mr. M. Jacoby on 



antennae fuscous, thorax closely punctured, elytra strongly punctate- 

 striate, the punctures often doubled, the interstices convex, femora 

 unarmed. 



Length 4-5 millim. 



Of rather elongate shape, the head finely and not very closely 

 punctured, the clypeus not or scarcely separated from the face, 

 transverse, similarly punctured as the head, antennae extending to 

 the middle of the elytra, fulvous, the terminal four joints fuscous, 

 second joint as long as the following ones, basal joint short and 

 thick, thorax nearly twice as broad as long, the sides but slightly 

 deflexed, feebly rounded, with a narrow margin, the surface slightly 

 more strongly punctured than the head, the sides more closely 

 so than the disc, the punctures of slightly oblong shape, scutellum 

 oblong, impunctate ; elytra subcylindrical, generally of paler 

 coloration than the thorax, the punctuation scarcely stronger than 

 that of the thorax, arranged in somewhat irregular rows, often 

 geminately, the interstices, especially at the sides longitudinally 

 costate, the punctuation distinct to the apex ; below rather darker, 

 the femora without a tooth, the posterior tibiae deeply emarginate at 

 the apex, claws bifid. 



Hah. Zambi (Belgian Mus. and my collection). 



This species agrees in every respect with PJicmhastus 

 except in the unarmed femora which even under a strong 

 lens show no sign of a tooth, but as this character is not 

 always to be depended on it would not be wise to separate 

 the insect generically; the female is much larger and 

 broader and the upper surface is frequently more aeneous in 

 colour than fulvous, but the apex of the elytra is in all the 

 specimens before me paler than the rest of the surface ; 

 the species is principally distinguished by the irregular 

 punctures forming the elytral strise and by the unarmed 

 femora, the prosternum is broad but scarcely sulcate at 

 the sides. 



Bhembastus mashonanus, sp. n. 



Dark piceous with aeneous lustre, the basal joints of the antennae 

 fulvous, head and thorax closely and rather strongly punctured, 

 elytra punctured in irregular rows, the punctures often double, 

 nearly indistinct near the apex, femora unarmed. 



Length 4 millim. 



Of elongate, subcylindrical shape, the head very closely and 

 rather strongly punctured, the punctures confluent at the clypeus, 

 the latter not separated from the face, its anterior edge straight,
