§ minor, 10*2 mm. The yellow markings on the abdomen are 

 very wide, so as to leave a narrow triangle of blackish brown ex- 

 tending over the middle of the first three segments, the remaining 

 segments being entirely dark. The rest of the body, the legs and 

 the antennae dark ochreous, the meso-epinotum somewhat reddish 

 ochreous. The scapes are longer than in the type species, extending 

 as far as the pro-mesonotal suture. Otherwise like the § minor of 

 the type species. This form of the § was taken with the Qj. which 

 are typical, so that the Q described by Forel doubtfully as belonging 

 to this race is evidently something else.

Race atramentarius, Forel.

"Identical with the type of the species, but nearly entirely black, 

 having only the flagellum, the bases of the legs and a narrow row 

 of spots on the abdomen, and sometimes a part of the thorax, of a 

 brownish dull yellow colour. A little more shining than the type of 

 the species. It recalls the var. melanoticus, Em. of race substitutus. 

 Passes into the type by every variety of colour. Tibiae not setose 

 Abyssinia." 



Also at Durban, (Wilms), (teste Forel, in Schultze, Reise Stid- 

 afrika, where the author raises it to the rank of a race). 



Race atramentarius, var. liocnemis, Emery.

"^. Smaller than the type species and more slender, maximum 

 length 10'5 mm. Head of the Qj. less large, x 3'2 x 2 - 8 mm.), with 

 the occipital angles more rounded; the tibiae are not setose, and 

 measure at the most only 3 mm. Sculpture feebler, whereby the 

 whole insect is rendered more glossy. Colour as in the type species, 

 but the contrast between the yellow and the black is even sharper." 

 Makapan and Pretoria; S.W.Africa (Lubbert), teste Forel, Schultze's 

 Reise, p. 20. I have not seen this form or the race atramentarius. 

 Notwithstanding the fact that in his original description Forel treated 

 atramentarius as a variety "passing into the type by every variety 

 of colour", yet in Schultze's Reise he raises it to subspecific rank
