 darker transverse baud (part ol" the — in dried specimens — 

 dark brown band cros-^ing the eyes immediately beljw the 

 large facets), face and occiput grey (former brownish grey 

 next eyes and on greater j)art of median depressed area), 

 basioccipital region, jowls, and sides of face clothed with 

 blackish or dark brown hair; eyes with an area of large 

 facets paler than and sharply couti'asting with remainder, as

 cynndrical-ovate or elongate-ovate, distal extremity usually 

 pointed ; first and second joints of antennce greyish cinnamon-

 triangle (difficult to distinguish in rubbed specimens) on each 

 segment from second to fifth inclusive; when abdomen is 

 viewed from behind at a low angle, ground colour of triangles, 

 as also that of pale hind borders to segments, appears greyish 

 pollinose ; on second and third segments triangles actually 

 clothed with white hair, as described in diagnosis above, are 

 often quite small, and usually do not extend forwards 

 beyond middle of segments, if so far ; on fourth and fifth
