tarsi reddish, femora brownish. The head is a little longer than 

 wide (wider than long in the type of the species), the sides slightly 

 compressed, and with a fairly distinct border on the sides of the 

 occiput, which is hardly visible in the type of the species. Antennae 

 somewhat more slender : the 9th and 10th joints of the nagellum 

 decidedly longer than wide (as wide as long in the type, hardly longer 

 than wide in var. signatum, Emery). Meso-epinotal suture obsolete. 

 Epinotal spines a little larger. The 1st node of the petiole is rounded 

 in front, and not truncate and marginate above as in the type and 

 in var. signata; it is wider and the sides are more convex; 2nd node 

 also wider. Otherwise similar to the type of the species. Mossamedes 

 (Picard)."

" $ . 6 mm. A little larger than the type. Thorax a little wider. 

 The 1st node is entire and obtuse in front, without the emargination 

 and the two partly effaced angles which are seen on the upper margin 

 in front in the ? of the type. 



" S (?) 4 - 8 mm. With the $ I received a $ , which I refer to 

 this species only with great doubt. 



" It has the wings of a Tetramorium, but has 12 joints to the 

 antenna, which become progressively shorter from the 2nd joint 

 onwards. The insect is dull, densely l-eticulate-punctate and rugose, 

 except the abdomen which is smooth. Ei-ect pilosity abundant ; the 

 nodes shaped as in soliclum. The epinotum is only bituberculate. 

 Head wider than long, strongly narrowed in front." 



Dr. Forel adds that it may belong to a distinct species, but the 

 analogies with solidum-grootensis permit of doubt on that point. 

 Or it may be a case of atavism, returning to a condition in which 

 12-jointed antennae were present.

"Differs from the type of the species in having the 1st segment 

 of the petiole longer, less excavated at the base above, and by 

 having the 1st abdominal segment finely striate transversely, and 

 not longitudinally as in the type ; the striatiou is visible only under
