Longicornia of South Africa, &e. 277 
Dark brown, slightly shining, covered with a very short, thin, greyish 
pile; head with a line of greyish hairs on each side of the face; man- 
dibles with the lower half and palpi glossy black; prothorax consider- 
ably broader than long, the lateral tooth short; scutellum rounded 
behind ; elytra coarsely and irregularly punctured, the punctures smaller 
towards the suture, and their edges mostly free from pubescence, so as 
to give the elytra, although obscurely, a somewhat marbled appearance ; 
body beneath and legs glossy brown, with a greyish-ferruginous pile ; 
antennz rather longer than the body, more attenuated than in the first 
species. Length 9 lines. 
Phryneta suturalis. 
P. subangusta, nigra, maculis albis pubescentibus ornata, una precipue 
supra suturam sita; corpore infra albo, nigro maculato. 
Hab. Old Calabar. 
Rather narrow for this genus, but not more so than P. c@ca, Chev.; 
deep black, glabrous, with dense spots or patches of white pile; these 
occur on the vertex, behind the eye, a stripe on each side of the pro- 
thorax and several small spots on the sides of the elytra, but principally 
in a long patch which extends from the scutellum to near the apex ; 
body beneath white, with various spots of black on the breast and 
abdomen, each of the segments of the latter, except the last, has six; 
legs and antenne (the fifth to the seventh joints principally) with 
indistinct patches of white. Length 9 lines. 
ORLETHUS. 
Caput latum, antice subtransversum, tuberibus antenniferis validis, basi 
approximatis. Oculi parvi, late et profunde emarginati. Antenne maris 
longissime, foeminze corpore haud duplo longiores, sublineares, scapo 
- incrassato, vix elongato, apice cicatricoso, articulo tertio longiore, czeteris 
brevioribus, ultimo parum crassiore. Prothorax quadratus, lateraliter 
spinosus. Llytra brevia, subovata, irregularia, spinoso-cristata, postice 
declivia, apice integra, humeris (spinis exceptis) nullis. Pedes mediocres. 
Pro- et meso-sterna simplicia. 
On the whole I think this genus approaches more nearly in 
figure and outline to Phrissoma umbrinum, White, than to any other 
Dorcadion-form known to me. The great length of the antennz in 
both sexes, their linear outline, and the general character of the 
prothorax and elytra will be quite sufficient to distinguish it. 
Oricethus longicornis. (Pl. XIII. fig. 1.) 
O. niger, fuscescente pubescens ; elytris basi et post medium fuscis, parte 
intermedia griseis. 
Hab. Natal. 
Black, covered with a light brownish pile, the middle of the elytra
