{Read April 4th, 1888.]} 
PuatE VII. 
Sagra opaca, n. 8. (Pl. VIL, fig. 7). 
Elongate, black, opaque; head minutely punctured; thorax 
longer than broad, impunctate; elytra finely punctate-striate, the 
apices impunctate, the strie slightly approached in pairs. 
3. The intermediate femora dilated into a strong triangular 
tooth; the posterior ones extending far beyond the elytra, their 
upper edge deeply channelled at the posterior portion, bounded 
above by an acute ridge, their base furnished with an ovate 
tomentose fulvous patch; their lower edge armed with a stout 
tooth near the apex; posterior tibiew slender, obsoletely bidentate 
near their apices. Length, 7—9 lines. 
Head very finely punctured at the vertex; antenne half the 
length of the body, black, the joints gradually increasing in 
length, finely punctured; thorax about one-half longer than broad, 
the anterior angles blunt, but slightly produced, the sides rather 
coneave, the surface impunctate at the disc, the basal portion 
with a few very minute punctures; elytra not raised at the basal 
portion, impressed within the shoulder, the punctures slightly 
approached in pairs, entirely disappearing near the apices, the 
interstices flat and impunctate without rugosities. 
Hab. Manboia, East Africa. 
The present species is evidently closely allied to 
S. bicolor and S. tristis: from the former it differs in 
the triangularly dilated and toothed intermediate femora, 
in the more elongate thorax, and in the shape and 
structure of the posterior femora, which are pro- 
portionately longer and more slender at the base; the 
first abdominal segment, like that of S. bicolor, is 
longitudinally depressed, but devoid of any fulvous 
pubescence as in the last-named species; there is also
