Delagoa, (Dr. Liengme). This form is somewhat transitional 

 between Barbarossa and Meinerti."

"£, 6-5-8-4: mm. Much smaller and less dimorphic than the type of 

 the race. It differs from it also by its deeply impressed pro-mesonotal 

 suture, which in profile forms an emargination hardly less deep than 

 that of the meso-epinotal. The head of the $ major is not so large, 

 and is more narrowed in front than in Arminius s. str., with which 

 it is otherwise identical." 



The above description is not entirely correct, owing to the fact 

 that the largest $$ or 2J. 2J. were not sent to Dr. Forel for examination. 

 A fuller description of all the forms is therefore added herewith. 



2)., 10 mm. Black, the apical margins of the abdominal segments 

 testaceous. Very similar to vividus-reginae, differing from it as 

 follows : — Head more reticulate-rugulose ; head and thorax almost 

 dull, the abdomen only slightly shining. Pubescence, and pilosity 

 fulvous, the pilosity much more abundant, especially on the abdomen 

 and anterior half of the head. The latter is very abundantly pilose, 

 the hairs being erect and inserted in large pit-like punctures. The 

 scapes barely reach the hind margin of the head. The median area 

 of the clypeus is longer than wide, distinctly narrower in front than 

 behind, not lobate in front, shallowly and longitudinally grooved in 

 the middle, feebly depressed behind the straight anterior margin. 

 Mandibles very finely reticulate and dull over the basal half, slightly 

 shining over the anterior half, fairly strongly punctured. They are 

 inserted at an appreciable distance from the corners of the anterior 

 margin of the head, as in some species of Myrmamblys. The eyes are 

 placed behind the middle of the sides. The head is one-sixth longer 

 than wide, not much wider behind than in front, the sides straight 

 over their middle three-fifths, the posterior margin shallowly concave. 

 The sides and declivity of the epinotum not vertical but oblique, 

 (nevertheless fairly steep), and, in consequence, the junction of those 

 surfaces with the dorsal surface is not rectangular as in reginae, but 

 rounded. The dorsum is convex transversely, feebly so longitudinally, 

 longer than wide. The declivity is as long as the dorsum, their 

 junction widely rounded. The scale is a little thicker, less convex 

 at the sides than in reginae, the summit feebly emarginate. Tibiae 

 much more compressed than in reginae.
