is less reddish than in the type-species. The head is more strongly 

 striate and more sharply and less sparsely punctured. The striae are 

 effaced along the middle of the head, which is distinctly shining, the 

 rest of the head being dull. The posterior margin of the head is very 

 slightly concave or almost straight. The thorax appears a little 

 narrower, owing to the mesonotum being less dilated in front 

 and the sides of the dorsum of the epinotum less divergent. The 

 declivity of the mesonotum is shorter than in the type of the species 

 and subvertical,sothat the meso-epinotal suture appears much narrower. 

 Epinotal spines variable, like those of the type, or sometimes a little 

 longer, but not more than one-third the length of the space between 

 their bases. The anterior half of the sides of the 1st joint of the 

 petiole, seen from above, are sometimes almost straight, but this 

 character is also variable, as half the specimens before me have the 

 petiole formed exactly as in the type of the species. The sculpture 

 of the thorax is perhaps a shade coarser than in the type.

This form, described by Forel as a distinct species, differs very 

 little from Godfreyi, i. sp., and merits at the most only varietal rank. 

 The specimens collected by Mr. Cooper are more strongly punctured 

 on the head than the others and are of a slightly darker colour.

^ • 3 - 8-4 - 6 mm. Black, flagellum and tarsi ferruginous. Man- 

 dibles castaneous brown. Pubescence on the abdomen shorter than 

 in the type. Sculpture similar, but stronger everywhere, the head 

 fairly abundantly punctured with small, sharply defined and pili- 

 gerous punctures. The pro-mesonotal suture is wider and deeper, 

 and the median tubercle of the mesonotum longer and distinctly 

 carinate, shining and more prominent than in the type of the species. 

 The declivity of the mesonotum is vertical, more abruptly delimited 

 from the anterior plane than in the type. The 1st joint of the 

 petiole is more trapezoidal, the sides converging more inwards pos- 

 teriorly ; there is a small and acute tooth on the ventral surface,
