and offers similar colour-varieties to those described from the B.. 

 Quango by Quedenfeldt. It is distinguished from its allies inter 

 alia by the usual green fasciae on the thorax and base of the elytra 

 being reduced to distinct spots. None of the numerous examples 

 collected by Mr. Bonny show a continuous basal fascia on the 

 elytra. 



Tragocephala nobilis, Fabr. 



One example of a variety in which the yellow basal fascia of tht 

 elytra is wanting. 



Tragocephala ? 



Three examples of a species apparently new, but so discoloured 

 that they cannot be profitably described. 



Tragocephala optjlenta, Harold, Col. Hefte, xvi. p. 228 ; Que- 

 denfeldt, Berl. eut. Zeits. 1883, t. i. f. 5. 



This fine species has previously been recorded only from the 

 Loango coast country. 



Alphitopola JANUS, n. sp. 



A. pallidse (Thoms.) quoad forniam simillima (thorace latiore, 

 transversa excepto) ; supra fulva immaculata, fronte, antennix, 

 pedibus corporeque subtics nigris ; subtilissime griseo-pubescens. 



Long. 18 millim. ^ . 



Subcylindrical, slightly narrowed behind, clothed above with a 

 reddish ochreous tomentum, the antennae, legs, and under surface 

 being shining black, with an extremely fine and short grey pile. 

 The forehead is also black, but this may be due to abrasion in the 

 specimen ; the tawny pile of the thorax clothes the flanks up to the 

 anterior coxae, and the side pieces of the mesosternum are similarly but 

 more thinly clothed. The thorax is short and broad, and its sides have 

 a minute and acute tubercle, but the two strong basal furrows and 

 ilexuous subapical shallow sulcus are precisely as in A. pallida. 

 The prosternum is narrow and simple between the coxae, and the 

 mesosternum produced into a conical tubercle as in the typical species 

 of the genus. The cicatrice of the scape is limited by a sharp, in- 

 complete ridge. 



Chareesthes aruwimia, n. sp. 



C. bellae (Z>aZm. = carissima, Westw.) similis et affinis ; differtpree- 

 cipue signaturis elytrorum, viz. fascia rufa subbasali oblique ad 

 sutaram descendente et antice ramulos duos ad basin emittente ; 

 fascia rufa postmediana cum maculis duabus marginalibus con- 

 juncta ibique guttam viridem includente ; area viridi apicali 

 maculis nigris liberis tribus, denique margine laterali sat late 

 fusco, macidis nigris quatuor anterioribus conjuncto. 



Long. 10| millim. 



There is one (imperfect) example only of this pretty little species, 

 which may be perhaps more correctly considered a locul form of the
