Race Weitzaeckeri, var. acanthobia, Forel. 



Log. cit., ty . 



$. 28-3 3 mm. Head longer than in the race, as long as 

 wide (not longer than wide as stated by Forel), barely narrower 

 in front than behind. In the race the head is clearly narrower in 

 front, and is also one-sixth wider than long. The sculpture of the 

 head is stronger in front, even the clypeus showing a fairly clear 

 longitudinal rugulosity. The thorax is quite dull (slightly shining in 

 WeitzaecJceri), more strongly sculptured than in the race, almost 

 longitudinally rugose. The declivity of the mesonotum is steeper and 

 longer, nearly as long as the anterior plane, more deeply concave 

 transversely. Seen in pi'ofile, the dorsum of the thorax rises from 

 front to back as far as the mesonotal declivity. The dorsum of the 

 epinotum is less widened towards the apex, and the spines are broader 

 at the base and shorter, or barely half as long as the interval between 

 their bases. The first segment of the petiole is as long as wide in 

 front, the anterior angles less abruptly rounded. It bears below in 

 front a short obtuse tooth, directed downwards.

The specimens from Durban which were also assigned to this variety 

 by Dr. Forel are quite different, having the broad head and other 

 characters distinctive of typical WeitzaecJceri, with which they should 

 be placed. They are duller and more strongly sculptured on the 

 thorax than Weitzaeckeri, but this character is too variable within the 

 group to justify the separation of the Durban specimens as a variety. 



The var. pensitata, Forel (loc. cit. p. 341) should be sunk as a 

 synonym of acanthobia. It is merely a little smaller and has the 

 angles of the 1st segment of the petiole more rounded. 



C. Liengmei, race caculata, Forel. 



(As race of C. Peringueyi) loc. cit. p. 341, ^ . 



£ . 3'5-4 mm. Colour as in var. acanthobia. Sculpture of the 

 thorax more reticulate and rugulose and a little stronger than in that 

 variety, [especially the dorsum of the epinotum, which is almost 

 rugose ; sides of the meso- and epithorax and of the segments of the 

 petiole sharply reticulate. Head globose, a little wider than long. 

 Thorax similar to that of acanthobia but more robust, the declivity of 

 the mesonotum as large and as sharply margined laterally as in that 

 variety, but meeting the anterior plane in a less acute angle. Meso- 

 epinotal suture deeper than in acanthobia. Dorsum of epinotum
