1904.] Catalogue of the Goleoptcra oj South Africa. 165 



The two species included in the genus are very delicate insects 

 remarkable for the very long slender hairs clothing the hind legs. 

 The genus is not recorded outside the South African limit. 



Key to the Species. 



Flavescent, with the frontal part of the head infuscate and with the 



prothorax and legs reddish, antennas flavous flavipennis. 



Fuscous, with the elytra straw-colour, antennae piceous titania.

Pering., Trans. S. Afric. Philos. Soc, 1888, vol. iv., pt. 2, pi. i., f. 10. 



Head black, clypeus, prothorax, and legs reddish, antennae and 

 under side flavescent, elytra pale straw-coloured ; clypeus transverse, 

 straight in front and with the outer angles not rounded, broadly but 

 not deeply punctate, clypeal carina sharp, frontal part impressed 

 and with a few shallow punctures bearing a long erect flavescent 

 hair ; antennae as long as the pedicel ; prothorax with somewhat 

 scattered punctures bearing each a very long erect hair equal in 

 length to those forming a dense fringe along the outer margins, the 

 punctures are a little more closely set on each side of the median 

 part of the disk, which has, however, an impunctate longitudinal 

 band, the basal part is sinuate and has a somewhat deep impression 

 in the centre of the sinuation ; scutellum very densely hairy, the 

 flavescent hairs appressed; elytra deeply and irregularly punctate, 

 each puncture bearing an erect setulose hair, they are faintly bi- 

 striate on the dorsal part in addition to the plain juxta-sutural stria, 

 and the outer margins have a thick fringe of hairs as long as those 

 on the prothorax, the pubescence on the pygidial part, the abdomen, 

 the pectus, and the femora is also very long and not appressed ; the 

 intermediate tarsi have very long setulose hairs at the apical part of 

 each joint, and the hind tibiae as well as the hind tarsi bristle with 

 erect line hairs, each one as long as the joints, the basal one of 

 which is longer than the second. 



Length 9J- mm. ; width 4 mm. 



Hah. Damaraland (Otjimbingue). 



Trichinopus titania, n. spec. 



Similar in shape to T. flavipennis, but differing not only in the 

 colouring (the body being fuscous with the elytra also straw-coloured), 

 but the clypeus is a little shorter, more broadly rounded laterally in
