88 Mr. 0. Thomas on the 



Choleva suturalis, sp. n. 



Narrow, subopaque ; pubescence slender, dense, ash- 

 coloured ; nigro-fuscous, the tibiae, palpi, and the basal two or 

 three joints obscure red. 



Thorax nearly twice as broad as it is long, base and apex 

 nearly straight, slightly curvate, and narrowed towards the 

 front. Scutellum minute. Elytra twice as long as broad, 

 gradually narrowed posteriorly, slightly impressed near the 

 middle ; sutural stride distinct, the sutural region from near 

 the apex to bej^ond the middle appears slightly convex; 

 apices individually rounded. Legs stout, intermediate tihice 

 curved, the spines of the posterior shorter than the basal 

 joint of the tarsi ; front torsi with the three first joints dilated, 

 fourth small. Antem^oi stout, longer than the head and 

 thorax, the basal three joints elongate ; fourth and fifth elon- 

 gate, but shorter than the preceding one; sixth quadrate; 

 seventh at least a third longer than the sixth ; eighth evidently 

 smaller than fifth ; ninth and tenth nearly similar to the 

 seventh. 



Sculpture close, consisting principally of transverse linear 

 marks, that of the elytra more distinct than in C. relata. 



This is without doubt most nearly allied to No. 2350 

 (C relata), but the thorax is more transverse and its anterior 

 angles are less contracted and depressed. The scutellum is 

 much smaller, the sutural region and apices of elytra are 

 different, and the body is even narrower.

 Mr. A. Philpott, together with a female of No. 2350, in 

 which the sixth joint of the antennas is transverse.

X. — On the Brush-tailed Porcupine of Central Africa. 

 By Oldfield Thomas. 



In 1887 the British Museum received, in the first and most 

 valuable collection presented by Emin Pasha, three skins of 

 a Brush-tailed Porcupine, which, in the absence of proper 

 West-African specimens for comparison, I referred * to 

 Atherura afiicana, Gray. Since then the skulls have been 

 extracted from the ty])e and other specimens from the West 

 Coast, and the Museum has also received additional material 

 from that region, among which the most noteworthy is a very
