closed mandibles) whereas the thorax is hardly 4 mm. long and at 

 the pronotum 2*5 wide. Mandibles with 6 or 7 teeth. Clypeus cari- 

 nate at least in the g minor, prolonged into a lobe in front, the 

 anterior margin of the lobe feebly emarginate in the middle. Head 

 of the $ major strongly concave behind. The whole thorax arched, 

 as in G. herculeanus. Scale entire, rounded at its upper margin like 

 that of C. sylvaticus, but a little thicker. Legs and antennae short. 

 Of an ebony-black colour, shining, the legs, flagellum, base of the 

 scapes and sometimes the thorax and mandibles of a more or less 

 reddish or yellowish brown. Apical margins of the abdominal seg- 

 ments narrowly yellowish. Head very finely reticulate, thorax less 

 finely reticulate-rugulose, less shining than the rest; abdomen very 

 finely rugulose transversely. In addition, there are some very sparse 

 punctures on the whole body, which are deep, large and abundant 

 on the mandibles and front of the head of the r $5 major. The man- 

 dibles are also very finely reticulate-punctate between the larger 

 punctures. A few long hairs on the body. Pubescence almost 

 identical with that of G. sylvaticus. Tibiae and scapes with a feeble 

 decumbent pubescence. 



9, 13-14*5 mm. Like the §, but the clypeus not carinate. A 

 median longitudinal impressed line on the anterior third of the 

 mesonotum, and two lateral longitudinal lines which do not reach 

 either the anterior or posterior margin, (as in natalensis i. sp.). Scale 

 entire. Colour, sculpture and pilosity as in the §. Mesonotum very 

 shining and very feebly reticulate. Wings nearly hyaline, but slightly 

 infuscate on the anterior margin, nervures and stigma brownish yellow. 



cf, 6-6*5 mm. Black, dull, except the abdomen which is slightly 

 shining; legs, antennae, mandibles and apical margins of the abdo- 

 minal segments more or less reddish brown. Wings a little darker 

 than in the Q. Head and thorax finely but very closely reticulate- 

 punctate. Scale thick, nodiform. Lobe of clypeus somewhat rounded. 

 Clypeus without a carina. There are two impressed longitudinal lines 

 parallel with the median line on the anterior third of the mesonotum, 

 and also lateral lines as in the 9- Pilosity and pubescence as in 

 the f ^."

This race is unknown to me in nature, but judging by the size, 

 compact form and shining integument, it appears to me to bear a 

 suspicious resemblance to the race Empedocles Forel. It certainly is 

 more closely allied to that race, if not identical with it, than to 

 natalensis, which is a much larger and differently shaped insect.
