$ media, 7-5-8-5 mm. These are the forms erroneously described bv 

 Forel as the £ major or 2J.. They resemble the 2J. in pilosity, pubescence 

 and sculpture, but the large pit-like punctures and the pilosity arising 

 from them on the front of the head are less plentiful. The head 

 is not like that of the 21, but resembles that of the 2j. of reginae, ha vine, 

 however, the posterior margin straight or very feebly convex. The 

 median area of the clypeus is wider, quite as wide as long, and without 

 the median groove. The scapes reach a little beyond the hind margin. 

 The scale is like that of the 2). . Mandibles longer, more feebly punc- 

 tured, less opaque on the basal half. 



$ minor, 5-5-6-2 mm. Like the $ media in sculpture and pilosity, 

 particularly of the head. The posterior margin of the head straight. 

 The scapes extend beyond the hind margin by two-fifths of their 

 length. Otherwise like the $ media.

21., 7-8-2 mm. Black; legs, antennae, mandibles and anterior 

 margin of the head dark red, the tarsi brownish red. Dull, the 

 abdomen moderately shining. Very closely and finely reticulate- 

 punctate, (the reticulations closer and the punctures much smaller 

 and shallower than in C. epinotalis Santschi), the extreme posterior 

 angles of the head rugulose and slightly shining. Abdomen very 

 finely rugulose and partly reticulate - punctate. Legs delicately 

 reticulate and feebly shining. Pilosity greyish yellow, very sparse on 

 the head and thorax, a little more plentiful on the abdomen, the hairs 

 on the epinotum and edge of the scale thicker and longer than 

 elsewhere. A feeble and decumbent pubescence present only on the 

 legs and antennae. Head, excluding the mandibles, subtrapezoidal, 

 wider than long, a good deal wider behind than in front, the posterior 

 margin straight, the posterior angles moderately rounded. Mandibles 

 nitidulous, very finely reticulate or shagreened, abundantly and 

 strongly punctured, 7-dentate. Median area of clypeus not carinate, 

 very slightly convex transversely, a little wider than long, feebly
