Knysna sulcicollis, Blanch., 

 Gymnoloma sulcicollis, Catal. Coll. Entom. Mus. Par., p. 67. 

 Male : Black with the legs reddish, except the hind tibiae and 

 tarsi, which are black ; head densely clothed with elongate, some- 

 what hair-like ashy-grey scales, prothorax with a median and a 

 supra-lateral band of similar scales which cover also the outer 

 margin, scutellum, elytra, pygidial part, and the abdomen clothed 

 with very closely set but not contiguous elongate scales of the same 

 pattern as those on the prothorax ; clypeus distinctly acuminate 

 but with the two apical teeth a little less reflexed than in 

 K. humeralis ; the prothorax has three longitudinal furrows, and 

 the scales, which are much more elongate and very dense, may 

 be said to cover the whole surface except the two median, some- 

 what raised longitudinal smooth areas ; elytra with only one distinct 

 discoidal costule, they are a little less parallel owing to a slight 

 median amplication, and the scales on the pygidium are not as 

 closely set as on the propygidium ; claw of the intermediate tarsi 

 with a conspicuous horizontal claw underneath. 



Female : Like the male, but less densely scaly, and wdth the 

 costule on the elytra more distinct ; the claw of the intermediate 

 legs has no tooth underneath. 



Length 6-7^ mm. ; width 2^3 mm.

I have always met this species di-agging itself clumsily along the 

 ground, and never in or on flowers.

 of the palpi, strongly dilated from there to the apex, where it is 

 straight with the angles distinct ; maxillae glabrous at the tip, and 

 armed there wath three apical sharp teeth bent almost at right angles 

 (the median one of which is slightly more apical than the other two), 

 and another trifid transverse one lower down ; the joints of the labial 

 palpi are short and the apical one is thick, sub-fusiform outwardly, 

 straighter inwardly, and the apical maxillary joint is a little swollen 

 inwardly, and straighter, but slightly sinuate outwardly ; antennae 

 nine-jointed, basal joint very swollen at the tip, second short, beady,
