 valido, prosferni minore. acuto. Antenna: ( cJ ?) corpore 2}aullo 

 longiores, rohitstce, apice acuminata', nrticadls arete conjunctis. 



Long. 16 millim. 



One example only. 



A closely- allied species from the Gaboon and Cameroons mimics 

 Phyneta nigropilosa (Aurivillius) in a similar way. 



Pachtstola decttssata, Che^Tolat. 



A single example of this Calabar species. It is hardly a true 

 Pachystola, the middle tibiae having & straight outer edge. 



Peteognatha gigas, Fabr. 



A single example, agreeing perfectly with others received from 

 Lagos. 



AcMocERA rNDULATA, Quedenfeldt, Berl. eut. Zeits. 1882, 

 pp. 185, 354. 



Found originally on the Quango river, examples from which 

 locality have been compared with those obtained by Mr. Bonny. 



Olenecamptus hofmanni, Quedenfeldt, Berl. ent. Zeits. 1882, 

 p. 355, t. vi. f. 10. 



Also found on the Quango. 



Frea MActTLicoENis, Thoms. 



A species apparently common in the Gaboon country on the 

 coast. 



DiCHOSTATES (?) BIMACULAXUS, U. Sp. 



Breviter et late ovatus, nigro-nitidus, maculatim albo-griseo-tomen- 

 tosus ; elytris grosse suhconjluenter punctatis, in f undo punctorimi 

 solunn tomentosis, utrinqueprope apicem macula penicillata nigra ; 

 ihorace brevi et lato, antice valde rotundatim angustato, laterihus 

 inermi, hasi transversim stdoato, margine hasali utrinque valde 

 sinuafo ; elytris hasi latis, humeris oblique subtruncatis. 

 Long. 11 millim. 



One example. The species belongs to a small group in which the 

 usual lateral tubercles of the thorax are absent. The short ovate 

 and broad form and the short triangular scutellum separate it from 

 Eumimetes. The antennae are as in Dichostates, the scape planed 

 beneath and much shorter than the third joint. In the example 

 described, doubtless a 2 , the antennae are shorter than the body and 

 the joints 5-11 short, the last pointed. The presternum is vertical 

 before and behind, and the mesosternum broad and vertical in 

 front. 



Dichostates collaeis, Chevrolat. 



Many examples, agreeing with others received from Old Calabar, 

 whence the species was originally described. It is found also at 

 Lagos and Cape Coast Castle, and extends, slightly modified in
