1896.] of the Coleoj^tera of South Africa. 113 



neath ; labrum (male) yellowish, apical margin narrowly infuscate ; 

 neck and prothorax closely and finely plicate transversely, the latter 

 slender, cylindrical, hardly grooved longitudinally in the middle ; 

 anterior and posterior transverse impressions not deep ; elytra very 

 narrow at the base and without any humeral angles, a little 

 ampliated from the middle to the apex ; suture not much raised ; 

 apical part ending in a short diverging acute spine on each side, 

 closely, deeply, and regularly pitted from the base to about the median 

 part, and closely punctured from there to the apex ; on each side of 

 the apical part there is a short narrow supra-marginal or almost 

 marginal yellowish band reaching nearly the base of the posterior 

 spine ; legs dark blue, knees and anterior tibiee slightly rufescent. 

 Female unknown. Length 13 mm. ; width 3 mm. 



The description of C. granulata, Dokt., applies to this specief, 

 but the elytra are deeply pitted in the anterior part, and not 

 granulated.

COSMEMA GLOEIOSA. 



Brassy, shining on the upper part, under side bright steel-blue ; 

 legs metallic blue ; head strigose ; labrum yellowish, with the base and 

 apex edged with black, but with the median part very faintly infus- 

 cate longitudinally ; head strigose ; antennae black, with the four basal 

 joints cyaneous ; prothorax very narrow, quite cylindrical ; elytra 

 elongate, much ampliate past the middle (female) broadly punctured 

 with the punctures closely set, and having on each side of the 

 posterior part a small, round, discoidal whitish spot, as well as 

 supra-marginal, humeral, short white band, and another and broader 

 one running from a little above the median part to the outer angle 

 of the apex. 



In shape and colour this species resembles much Myrmecoptera 

 nobilitata, Gerst., from Lake Jipe (Zanzibar miainland), but is dis- 

 tinguished by having filiform instead of foliate antennae ; the lateral 

 white band is also somewhat different. Its nearest South African 

 ally is Gosmema tenella. 



Judging from the shape of the supra-marginal white band, I am 

 inclined to believe that in some specimens the posterior part will 

 be disunited from the median. Length 16 mm. ; width 5 mm. Male 

 unknown.
