230 ME. M. Jacoby ok the [Mar. 15, 



strongly punctured than the thorax, the punctures closely placed 

 uear the suture, the interstices towards the sides transversely 

 rugose ; legs fulvous, the anterior femora much thickened and 

 dilated into a tooth. 



Hab. Salisbury, Mashoualaud ( G. Marsliall), obtained by beating 

 in September. 



In the female the thorax is slightly narrowed in front, and the 

 antennio are much shorter and have the third and fourth joints of 

 equal length, the apical ones are slightly stained with fuscous. 



PsEUDOCOLASPis cosTATA, sp. nov. (Plate XXII. fig. 12.) 



Metallic green, the femora and tibia? more or less cupreous ; 

 thorax transversely rugose, with a narrow latei-al cupreous band ; 

 elytra with deep basal depression, strongly punctate-striate, the 

 interstices very strongly longitudinally costate. 



Length 5 millim. 



Head very closely rugose-punctate, the interstices minutely 

 granulate, metallic green, a narrow- margin round the eyes and the 

 sides of the clypeus reddish cupreous ; clypeus not separated from 

 the face, deeply punctured, its anterior edge concave, palpi piceous ; 

 antennae dark blue or purplish, the last five joints very robust and 

 strongly thickened ; thorax subcylindrical, constricted anteriorly 

 and posteriorly, the surface closely and deeply punctured, the 

 interstices everywhere transversely rugose, the middle of the disc 

 slightly depressed, bright metallic green, the sides with a narrow 

 cupreous band : scutellum subpentagonal, with a few punctures ; 

 elytra much wider at the base than the thorax, the shoulders 

 acutely raised, the basal portion with a deep transverse depression 

 which is closely punctured, the base itself also with iri'egular rows 

 of strong punctures which become more obsolete below the 

 depression, each elytron with about eight strongly-raised costse, 

 metallic green, the sides narrowly purplish ; imderside and legs 

 metallic green, the apex of the femora and the tibiae more or less 

 cupreous, tarsi purplish. 



Hah. Cameroous ((7o>i>-«(?). 



This is a handsome species, well distinguished by the system 

 of coloration and the strong elytral costaj ; I received a single 

 specimen from Dr. Ivraatz. P. mpreo-marginata Jac. is nearly 

 identical in coloration, but the elytra have no depression and the 

 sculpture is entirely different, yet it is not impossible that the 

 present insect is only the male of the one last named. 



PSECDOCOLAPSIS LATERALIS, Sp. UOV. 



Puscous, the basal joints of the antennae and the tibiae and tarsi 

 fulvous ; thorax finely and closely punctured,with silvery-grey hairs, 

 its anterior mai-gin fulvous ; elytra finely punctured, with rows of 

 stiff hairs, the disc obscure metallic, the sides broadly f ulvo-piceous ; 

 femora mucronate. 



Length 5 millim. 



Head deeply rugose-punctate, the middle with a small tubercle,
