MaJacosoma transvaalensis, sp. n. 



Black, the head impunctate ; thoi-ax fulvous, extremely- 

 minutely punctured ; elytra more strongly and closely punc- 

 tate ; legs black. 



Length 4 millim. 



Head black, impunctate, the frontal tubercles strongly 

 raised, trigonate ; the clypeus narrowly transverse, with a 

 broad and highly raised central ridge; anterior edge of the 

 labrum testaceous ; antennas short and robust, scarcely ex- 

 tending to the middle of the elytra, black, the second joint 

 not much shorter than the third, which is very nearly as long 

 as the fourth, all the joints somewhat triangularly thickened, 

 the apical one more elongate ; thorax subquadrate, the sides 

 slightly constricted near the base, more rounded at the middle, 

 the angles distinct, slightly tuberculiform, the surface with a 

 few very minute punctures, pale fulvous ; scutellum small, 

 black ; elytra much broader at the base than the thorax, much 

 more distinctly although finely and closely punctured, of the

 Hah. Zoutpansberg. 



Very closely allied to M. capitatum, Jac, but the entire 

 underside and legs black, the antennas of the latter colour and 

 with shorter joints, the general size of the insect smaller ; in 

 the female the antenna? are shorter still and only reach to the 

 base of the elytra. 



^nidea imitans, sp. n. 



Black, the femora and the tibise fulvous ; head and thorax 

 greenish, the latter deeply transversely sulcate, nearly im- 

 punctate ; elytra finely punctured, flavous, the sutural and 

 lateral margins metallic dark green. 



Var. — The lower part of the face, the basal joints of the 

 antennae, the thorax, elytra, and legs flavous. 



Mas. — Head deeply excavated below the antennas; the 

 base with a thorn-like projection. 

 Length 5 millim. 



Mas. — Narrowly parallel, the head broad, greenish black, 

 impunctate, the frontal tubercles strongly raised, triangular 

 and pointed, divided by a deep longitudinal groove, the lower 

 portion of the face thickened below the eyes, deeply exca- 

 vated above the clypeus, the cavity furnished with some 

 hairs and a tooth or thorn-like lamina at the upper portion ; 

 palpi thickened ; eyes globular and rather large ; antennge 

 long and slender, black, the first joint very robust, strongly
