114 Psyche [October 



an enlargement of from 25 to 60 diameters the annuli show dis- 

 tinctly and the roughening is due to rows of minute granules on the 

 annuli; the third joint is yellow with a dark brown spot at the base. 

 In this respect the genus seems to be closely related to Neopachy- 

 gaster, the glossy brown spot on the antennal joint, which Malloch 

 refers to as "possibly of a sensory nature," is here largely devel- 

 oped. The only other character that seems to separate the two 

 genera is the form of the scutellum. The side view given of C. 

 minuta (fig. 19a) shows two small dorsal protuberances at the 

 suture that are not mentioned in the description, nor are they 

 shown in the dorsal view (fig. 19).

The apex of the scutellum is slightly shorter and less attenuated 

 in this and the following species, than in P. minuta Will.

? Front black, orbital margins whitish, face white, antennte 

 yellow, the third joint with five narrow annuli, with a small brown 

 basal spot, arista yellow. Thorax black when viewed from above, 

 the yellowish tomentum forming a dorsal line extending just beyond 

 the suture where it expands into a broad patch in front of the scu- 

 tellum; there is also an obsolete transverse band in front of the 

 • suture; from the humeri large patches of whitish tomentum extend 

 to the base of the wings and across the pleura; base of the scutel- 

 lum with yellowish tomentum. Abdomeli black, looking from be- 

 hind the fourth segment has three lines of white tomentum, with 

 only the dorsal line showing on the fifth segment, third segment 

 with only a lateral patch when viewed from the side. Legs yel- 

 low, femora except at the tips dark brown, front tibiae also brown, 

 halteres white. Wings hyaline, costa and first longitudinal vein 

 dark brown, stigma yellow, length, 3 mm.
