200 Mr. Edward Saunders on 



Like Bosx r. trimmerana in colour but narrower and in form more 

 resembling the 5 of biicephala, and evidently belonging to that group 

 by the form of the antennae. I thought at first it was identical with 

 macilenta, Perez, but of that species the author says, "abdomen tres 

 luisant " whereas in this species it is duller than in rosx. The 2nd 

 joint of the flagellum in the male is about equal in length to the 

 following 2 together, in the 5 about as long as the following 3. The 

 rest of the joints slightly longer than broad in the ^ , distinctly so 

 in the 9 ) hairs of tlie face in the ^ brown margined with black, 

 in the $ black throughout, thorax clothed with bright brown hairs 

 those of the sides jjaler, propodeal area very finely sculptured its 

 margins slightly shining, abdomen narrow, not wider than the thorax 

 in the $ , nearly dull, finely rugulose with a remote puncturation 

 which recalls that of the humilis group ; 1st and 2nd segments 

 sparingly clothed with long brown hairs, apices of the segments 

 narrowly, discoloured, the 2ud and 3rd in fresh examples with an 

 apical fringe of brown hairs ; 4th, 5th, and 6th segments clothed with 

 black hairs, hind tibiaj very narrow, scopoe very small. Process of 

 8th segment in the ^ rather short and wide, sharply elbowed near 

 the base, its apex truncate, and its sides fringed with hairs which are 

 shorter towards the apex, armature with its lobes slightly produced 

 in front. 



Long. 10-12 mm.

This specimen is closely allied to scJmiiedeknechti but 

 has the 3rd and following segments clothed with black hairs, 

 in this respect it more closely resembles nigrifrons, Smith, 

 but lacks the pale bands at the apices of the 2nd, 8rd, and 

 4th segments ; as I do not feel sure that it may not be a 

 colour variety of one or other of these closely allied species 

 I refrain from describing it.
