the disc crowded with small punctui'es, which at the sides are some- 

 what confluently rvigose, cupreous, more shining than the head, all 

 the margins narrowly dark blue, the base with two large transverse, 

 irregular blue patches ; scutellum dark blue, finely punctured at 

 the base ; elytra without basal depression, cupreous, moderately 

 shining, the suture and the lateral margins dark blue, the disc 

 finely punctured in rows near the suture, more irregularly so at 

 the sides, where the interstices are finely transversely wrinkled ; 

 underside and legs dark violaceous blue, finely pubescent, the 

 anterior tibiee slightly curved ; femora unarmed. 



Hah. Beira, E. Afiica {^A. 8heppar(C). 



This species is not difficult to recognise on account of its system 

 of coloration and the opaque, non-impiessed head ; the elytial 

 lateral rugosities are very fine, extend to the apex, and ai'e finely 

 pubescent near the lateral j^ortion ; the female has much shorter 

 antennae and straight tibite, but does not difier in any other respect. 



COLASPOSOMA MIRABILE, Sp. n. 



Cupreous below, above metallic green, sides of the head dark 

 purple ; thorax finely and subremotely punctured, with six 

 purplish bands ; elytra strongly and closely punctured, the sides 

 transversely rugose and with a longitudinal costa, each elytron 

 with two purplish, broad, longitudinal bands. 



Length 5 millim. 



Fem. Head rather closely punctured and minutely granulate, 

 without depressions, the sides reddish cupreous, a central narrow 

 line at the vertex and the clypeus metallic green ; labrum black ; 

 antenna? with the terminal joints thickened, black, the lower 

 three joints fulvous, the following two greenish ; thorax rather 

 short, the sides moderately rounded, slightly narrowed anteriorly, 

 the disc finely and rather remotely punctured, metallic green, 

 the sides and four longitudinal bands dark cupreous ; scutellum 

 finely punctured, cupreous ; elytra strongly punctate- striate near 

 the suture, the sides strongly transversely rugose, with aii acutely 

 raised longitudinal costa from below the shoulders, the suture 

 narrowly and a broad lateral band metallic green, rest of the 

 surface dark cupreous; below cupreous, finely pubescent, the 

 anterior femora with a small tooth. 



Hah. Luitpoldkette, E. Africa. 



In its coloration this species much i-esembles C. viridivittat'am 

 Baly, but is of much less convex shape and smaller, the punc- 

 tuation of the thorax is totally difierent and also its coloration ; 

 this difierent sculpturing distinguishes the species likewise from 

 C. variahile Jac, which is also more than twice as large. I unfor- 

 tunately know the female sex only ; the male is probably devoid 

 of the elytral costae.
