purple reflections, the head darkest; pterothorax with bright orange 



pigment ; first abdominal segment orange, with a line of brown along 



sides and base ; second and third segments 

 clear white in apical two-thirds, brown at 

 base ; last segment lemon yellow ; antennal 

 segments 1-4 clear pale yellow, 5-9 dark 

 blackish brown; fore femora orange, shad-

Head about two-thirds as long as wide, 

 smooth and shining above, sloping evenly to 

 base of antennae, the dorsal outline of 

 cheeks, eyes and front of head almost 

 exactly semicircular ; frontal costa broadly 

 rectangularly emarginate; a pair of rather 

 prominent bristles between anterior and 

 posterior ocelli, two pairs of smaller posto- 

 cellar bristles, and a few still smaller bris- 

 tles on cheeks and eyes ; ventral surface of 

 head flattened, densely hairy, produced an-
