said "at the sides," as the space near the suture is scarcely visibly 

 rugose ; some specimens are of an feneous colour above with the 

 interior of the punctures metallic green, 



COLASPOSOMA BALYI, Sp. n. 



Dark blue or violaceous ; thorax with feebly i-ounded sides, 

 extremely closely and sti'ongly punctui-ed ; elytra of nearly similar 

 sculpture, the sides scarcely rugose. 



Length 9-10 millim. 



Mas. Head strongly punctured, the sides rugose, clypeus rather 

 more finely and closely rugose-punctate, labrum black ; antennae 

 entirely bluish black, the terminal joints strongly widened ; 

 thorax not veiy strongly convex, the sides feebly rounded, the 

 anterior angles acutely pointed in shape of a small tooth, the disc 

 extremely closely evenly and strongly punctured, the punctures 

 round and deep, the interstices very slightly wrinkled at the sides ; 

 scutellum broader than long, punctured at the base ; elytra 

 punctured like the thorax, the punctures very closely placed, the 

 interstices slightly rugose, at the sides; penis rather slender, 

 strongly curved, the apex triangularly pointed ; anterior tibiaj 

 dilated and curved at the apex. 



Hah. Dar-es- Salaam, E. Africa. 



Allied to C. kraatzi Jac, but less shining, the upper surface 

 strongly and much more closely punctured, the punctures 

 of the thorax and the elytra equally strong. The female does not. 

 seem to differ from the other sex excepting in the straight and 

 not dilated anterior tibiae. In C. variabile Jac. the male has a 

 strongly convex and rather dilated thorax and the elytra are 

 strongly transversely rugose at the sides. 



CoLASPOSOMA ASPERATUM Faimi. (Ann. Soc. Ent. Belg. 1902, 

 p. 262). 



This name has long ago been used by Lefevi-e for an Indian 

 species (Catal. Eumolp. 1885, p. 104) : I therefore alter it to 

 C. pemeri, nom. n. 



COLASPOSOMA BEIRAENSE, sp. n. (Plate XVII. fig. 10.) 



Dark blue below, above cupreous, the anterior portion of the 

 head and two basal sj)ots on the thorax dark blue ; head and thorax 

 densely punctured ; elytra finely punctured, the sides finely trans- 

 versely rugose, the sutural and lateral margins metallic blue. 



Length 6-7 millim. 



Mas. Head opaque, finely and closely punctured and granulate, 

 flat, without depi'essions, cupreous, the lower portion in shape of 

 a triangular patch, dark blue, this colour dividing in a narrow 

 line the cupreous portion ; labrum j)iceous ; antennae with the 

 lower five joints dark fulvous, the basal joint above and the 

 terminal joints piceous, all the joints with the exception of the 

 first slender ; thorax strongly ti-ansversely convex, the sides 

 strongly rounded, narrowed anterioi'ly, the angles not produced.
