sides. Thorax finely and longitudinally rugose, constricted between 

 the meso- and epinotum, the latter with two acute spines, directed 

 backwards, upwards and outwards. Petiole shaped as in C. scutellaris. 

 Abdomen shining, exceedingly finely rugulose. 



" $ . 7-8 mm. Dark reddish-brown, partly brownish-black, parti- 

 cularly the mesonotum ; pilosity sparse. Head and petiole as in the ^ . 

 Thorax finely longitudinally rugose ; epinotum with two small teeth, 

 wide at their bases. Sculpture of abdomen as in the £> .

The above description is insufficient, but from Mayr's table of South 

 African species in the Ann. K.K.N.H. Mus. the following additional 

 characters may be extracted : 



The second segment of the petiole has a deep median groove, and 

 all the joints of the flagellum are as long as, or longer than wide, 

 excepting the third, which is a little wider than long.

" ^ • Differs from the type of the species by its spines, which are 

 longer than half the interval between them, and by its entirely brown 

 colour. 3-36 mm. (a little smaller than the typical capensis). 



" Delagoa (Dr. Liengme)." 



A co-type of this variety, in my collection, has the head very super- 

 ficially sculptured or almost smooth, excepting the area between the 

 eyes and the front of the head, which is finely and longitudinally 

 rugulose-striate. In addition, contrary to Forel's statement, the epinotal 

 spines are barely half as long as the interval between their bases.

^ • 3 - 4-3 - 9 mm. Head, thorax, petiole and antennae reddish- 

 brown, abdomen piceous brown, legs brown with the tarsi a little paler. 

 Pilosity short and scanty, absent except ontheclypeus and apical margins 

 of the abdominal segments. Pubescence very sparse, short and decum- 

 bent, almost entirely absent on the head and thorax. Head dull, closely 

 and fairly finely reticulate, here and there somewhat reticulate rugulose, 

 the reticulations near the inner margins of the eyes emphasised longi- 

 tudinally ; a longitudinal area on the vertex with the sculpture some- 

 what effaced and moderately shining. Mandibles dull, strongly striate. 

 Thorax fairly dull, very regularly reticulate, the strands of the reticu- 

 lation sharply defined and narrower than the spaces which they
