486 MR. H. \*. BATES ON [June 17, 



' Callichroma afrum, Linn. 

 Recorded from several distant points alonp; the West-African 

 coast — Loango, Old Calabar^ and Sierra Leone. 



Callichroma barbiventris, n. sp. 



C. afro (Linn.) affirms ; differt thorace haucl passim transversim 

 striato, disco utrinque granulosa nigro-velutino, ventreque medio 

 dense fulvo-hirsuto. 



Long. 18 millim. 



Similar in form and colours to the Tropical- American C. rugicollis 

 (Guer.). Bright metallic green ; elytra darker and velvety opaque, 

 ■with a sutural vitta narrowing and ending before the apex of the 

 scutellum, transversely pubescent and yellow ; labrum, antennae, 

 and legs red. The head is densely confluent punctulated ; the scape 

 short, subovate-clavate, and transversely rugose. The thorax is 

 moderately long, the anterior constriction slight, the posterior 

 stronger and with two transverse wrinkles in the groove ; the 

 surface is transversely wrinkled only on the two anterior slight 

 elevations and partially on the sides, the middle part being closely 

 confluent punctulate, with a dark velvety patch on each side. The 

 scutellum is densely punctulate and opaque. The underside is 

 lighter metallic green with a silky-tawny pubescence, which (at 

 least in the male, the only sex known) on the metasternum and the 

 middle of the ventral segments is long and erect. The fifth and 

 sixth ventral segments are both very deeply emarginated in the 

 same sex. 



C. piliventris (Bates), from the Gaboon, which is similarly 

 pubescent on the underside, much denser in the male than in the 

 female, and has also deeply emarginated fifth and sixth segments in 

 the male, is a more robust insect, with broader thorax, and differs, 

 moreover, in the black colour of the antennfe and tibiae and the pale 

 hind tarsi. 



Callichroma ? 



An apparently new species, but the single example is in tdo 

 inutilated a condition to be satisfactorily described. 



Mecaspis setulicollis, Quedenfeldt, Berl. ent. Zeits. 1882, p. 327. 



A single very imperfect specimen agrees well with the above-cited 

 description drawn up from Angola examples. The species is very 

 closely allied to M. subvestita (Bates) from the G-aboon, differing 

 only in its greenish-blue colour (M. subvestita being violaceous) and 

 the much finer and more scattered punctuation of the more elevated 

 |)art of the elytra. 



Philematitjm virens, Linn. Mus. Lud. Ulr. p. 73. 



A widely distributed insect on the West Coast of Africa. Linnaeus 

 gave the erroneous locality "America" to the species, for which, in 

 the 12th ed. of the ' Systema Naturae,' he substituted "India." 

 Olivier confounded it with a West-Indian species, and consequently
