lie, but seen, in some views, to bear a thin covering of pale 

 tomentum; basal segment at the sides apparently with only one 

 or two brisitles, which are not easily seen. Hypopygium im-

19. P homocophancs, sp. nov. 



Male: front of head and face black, the surface not concealed 

 by pale tomentum, but nearly bare; posteriorly the head, is dark, 

 but greyish tomentose at the sides. Antennae with the third 

 joint dark, not acutely pointed at the apex. 



Thorax with fuscous itomentum, more greyish at the sides in 

 front, and on the pleura, denser and grey on the metanotum; 

 scutellum at the most with a few excessively short fine hairs, 

 very indistinct; halteres pale, dark at base. Wings subinfuscate, 

 neuratidn black, sitigma brown, third and fourth costal segments 

 not dififering much in length, upper extremity of posterior cross- 

 vein before the apex of the second longitudinal. Legs pitchy, 

 knee joints and tarsi paler, brownish or brownish yellow. 



Abdomen deep black, with pale lateral spots, which on some 

 segments unite to form apical bands; fifth segment shining in 

 some aspects, as probably are the other parts occupied by pale 

 spots, if the tomentum be removed; basal segment on each side 

 with about three black, longish bristles; hypopyigium bent to the 

 right and the tip with a large impression. Length 2.5 mm.

 antennae black, bare and shining; posteriorly fuscous in the 

 middle, grey laterally. Antennae with the third joint yellow, not 

 sharply pointed at the tip, nor at all produced. 



Thorax somewhat shining, nigroaeneous, beneath a thin cov- 

 ering of fuscous tomentum, metanotum much more densely 

 clothed with greyish white; scutellum with extremely short and 

 fine marginal hairs; halteres pale, dark at base. Wings hardly 

 clouded, third costal segment in the male distinctly longer than 

 the fourth, but in the female the difference in length is less, and
