1890. J COI.EOPrERA FROM CENTRAL AFRICA. 485 



Par(eme veerucifer, n. sp. 



P. (Coref-.hrogaster) annulipedi, Ohevr., multo rohustior, cinna- 

 momea, hnviter puhescens ; genis ante oculos, maiidibulis femori- 

 busque apice nigris ; thorace latlore, transversa tuberculo dis- 

 coidali valde elevato, laterali mediano obtuse conico, lateribusque 

 posticis valde sinuatis, an'jidis posticis prominentibiis. 



Long. 33 raillim. $ . 



Of similar elongate form to P. annulipes, but broader, rufescent- 

 cinnamon in colour, with the short genae in front of the eyes, 

 antenniferous tubercles, and mandibles blackish, and the apical 

 fourth of the femora and extreme base of the tibiae also black. The 

 whole surface is sericeous-opaque, the elytra very minutely and 

 closel)'^ punctulate-rugose, with two extremely narrow costse on each, 

 the apices conjointly rounded, without trace of sutural tooth. The 

 thorax is nearly twice as broad as long, the surface with many (four 

 or five) flattish tubercles on each side and one in the middle of the 

 disk elevated and subcompressed ; the medio-lateral tubercle is very 

 broad, subconical, and the sides behind it rather deeply sinuated in 

 connection with a strong transverse subbasal groove. The antenna} 

 reach to about four fifths the length of the elytra ; the scape is thick, 

 oblong, abruptly constricted at the base, longer than the third joint, 

 which as well as the fourth is shorter than the fifth and following ; 

 the second, third, and fourth are slightly nodose at the apex, fifth 

 and tenth subserrated. The antenniferous tubers are acutely denti- 

 form. The elytra are unarmed at the sutural apex, very densely 

 subconfluent punctate and pubescent. By the proportions of the 

 third to fifth antennal joints and the slight nodosity of the second 

 to fourth, this large species appears to belong to Parceme rather than 

 to AUogaster. Unfortunately the female only is known, 



XrsTROCERA NiGEiTA, Scrville. 



This species seems to be very widely distributed in Tropical Africa. 

 Serville described it from Senegal examples. The specimens from the 

 R. Aruwimi do not differ from others found in Usambara. E. Africa, 

 with which I have compared them. 



Callichroma feagrans, Dalman, Schdnh. Syn. Ins., App. p. 150. 



A robust species with concolorous elytra, i. e. without lighter 

 sutural stripe, and distinguished from "its nearest allies by the 

 patches of dense silky golden-tawny pubescence on the sides of the 

 ventral segments. The thorax is very finely transversely striated, 

 the strife broken and granulated on each side of the disk. In Dalman's 

 described examples from Sierra Leone the antennaj and legs were 

 wholly rufous ; but the colour of the antennaj is variable, being 

 sometimes dark reddish brown with the scape rufous, or entirely 

 reddish brown and even black. I have seen specimens from Sierra 

 Leone, Cape Coast Castle, and Cameroons. The two examples from 

 the Aruwimi have dark antennae.
