recogiiise the other differences indicated by Forel. The petiole is 

 precisely similar to that of the type, and the sculpture is quite as strong.

Var. matabele, n. V. 



£. 4"l-5'2 mm. Head and thorax of a warm reddish-brown, 

 abdomen piceous, legs dark brown, the articulations, tarsi, flagellum 

 and mandibles reddish-ochreous. Very similar to var. amita, but 

 differing from it in colour, size, and also in the following characters. 

 The fundamental reticulate sculpture of the thorax is much sharper 

 and more coarse. The superimposed rugae on the pronotum finer 

 and less regular than in amita. The pro-mesonotal suture is con- 

 siderably wider and deeper, and joins in the middle a longitudinal 

 impression which divides the pronotum into two (visible also in 

 amita, but much less distinct). The anterior plane of the mesonotum, 

 seen from above, is almost pentagonal in outline, the posterior half of 

 the sides sharply marginate, the declivous plane also marginate,

longer and steeper than in amita (in some specimens almost vertical). 

 The median tubercle is also more sharply carinate and longer than in 

 amita. The epinotal spines are as long as in the type-species, less 

 divergent and directed more upwards than in amita. The median 

 longitudinal impression on the dorsum of the epinotum is even 

 sti-onger than in that variety.

Not unlike C. Bequaerti, Forel, from which it appears to differ 

 by the weaker sculpture, the much smaller eyes and the pro-mesonotal 

 suture, which is very Avide and deep at the sides.

 ^ . 3-39 mm. Head and thorax varying from a dull ochreous yellow 

 to dark yellowish or l-eddish-brown, the anterior third of the head 

 usually paler. Abdomen dark brown, becoming paler or more reddish- 

 yellow towards the base. Antennae, legs and mandibles dark ochreous, 

 the tibiae and femora more or less brownish-yellow. Pubescence
