290 Additions to the Longicornia of South Africa, Sc. 
The above characters are drawn up from a male; what I have 
very little doubt is, the female is somewhat larger, with a more irre- 
gular prothorax, shorter antenne, and that remarkable peculiarity 
of abdomen which is found in the female Obriwm and some cognate 
genera—that is to say, the second abdominal segment having a large 
semicircular depression filled with hairs, and the remainder of the 
segments, also covered with hairs, more or less withdrawn within 
the second. Megaproctus, an anomalous genus from the same country, 
was placed by M. Chevrolat with the Obriine solely on this account ; 
but as modifications of this structure are found in other groups, it 
does not appear that any great value should be attached to it. In 
the present genus, having regard to the habit, peculiar distribution 
of colours, form of the antenne, imperfect elytra, and legs (except 
the posterior femora), I know nothing so nearly approaching it as 
Akiptera. Indeed, with Bimia and Agapete, I think the four genera 
will form a subfamily allied in some respects to Hesthesis. 
Psebium brevipenne. (Pl. XIII. fig. 2, 3.) 
P, nigrum; capitis fronte et lateribus, elytris basi, femoribus anticis et 
intermediis (basi excepta) fulvis. 
Hab. Natal. 
Black ; front, above the lip, and sides of the head, anterior and inter- 
mediate femora (except at the base), and the basal half of the elytra 
pale yellowish; head greatly exserted, but not constricted behind, con- 
cave between the antennee, face short; prothorax shining, a slightly 
raised tuber on each side of the disk; scutellum rounded behind ; 
elytra narrowed and rounded towards the apex ; posterior legs covered 
with short stiffish hairs; body beneath black, the abdomen greyish 
brown, the throat yellow. The female has the head, prothorax, the 
greater part of the elytra, and the body beneath yellowish. Length 
(3) 5 lines, ( 2 ) 63 lines. 
CRIODULE. 
Caput antice transversum, convexum, tuberibus antenniferis validis, basi 
approximatis. Oculi angusti, late emarginati. Antenne corpore lon- 
giores, graciles, haud pilose; scapo modice elongato, articulo tertio 
longiore, ceteris decrescentibus. Prothorax oblongus, basi angustior, 
lateraliter minute dentatus. E/ytra elongato-ovata, regularia, ad latera 
fere parallela, apice singula rotundata. Pedes graciles; femora modice 
incrassata; tébie anticxe rect, intermedi fortiter emarginatie ; tars? 
intermedii et postici articulo basali duobus sequentibus simul longiore. 
Prosternum angustum depressum. Mesosternum declive. Corpus sub-

This genus should have been placed after Nonyma, from which it
