Two New Trypetidae from China. 



BY D. W. COQUILLETT. 



Trypeta quinaria n. sp. 



Yellowish, the metanotum largely black. Lower front corner of the 

 third antennal joint produced in the form of a sharp tooth, arista short- 

 plumose. Body somewhat polished. Wings hyaline, marked with five 

 brown crossbands, all except the first two crossing the wing ; the first 

 band is at the humeral cross vein ; the second begins at the apex of the 

 auxiliary vein and extends to the sixth vein ; the third begins at the 

 apex of the first vein, passes over the small cross vein, ending just be- 

 yond the tip of the sixth vein ; it is connected with the preceding band 

 by the brown stigma ; the fourth band begins at a point midway be- 

 tween the apices of the first and second veins and passes over the hind 

 cross vein ; the fifth band extends from the tip of the second vein to 

 the middle of the second posterior cell, leaving the broad apex of the* 

 first posterior cell in the hyaline portion ; third vein bristly to the last 

 brown band ; small cross vein near the middle of the discal cell. Length, 

 5 to 7 mm.

 brown, its lower front corner produced in the form of a sharp tooth ; 

 arista long-plumose ; proboscis brown, palpi yellow. Thorax yellow, 

 opaque gray pruinose, the center of the mesonotum and lower part of 

 the pleura brown; scutellum yellow and with a basal triangular brown 

 spot, four scutellar bristles. Abdomen yellow, a median spot on the

 basal segment of the ovipositor, black. Legs yellow, the femora largely 

 brown. Wings brown, rather sparsely covered with hyaline spots and 

 dots; stigma brown, its apex yellowish hyaline; between apices of the 

 first and second veins are two hyaline spots ; between the apices of the 

 second and third veins is only one hyaline spot, situated just beyond 

 the tip of the second vein ; the first posterior cell contains two hyaline 

 dots alternating with two transverse pairs of hyaline dots ; the hyaline 

 dot in the apex of this cell is nearly one-third as wide as the cell ; 

 the discal cell contains three transverse pairs of hyaline dots; the 

 ground color of the wings is of several shades of brown, and is varied 

 by a few rather large yellowish spots : third vein bristly nearly to its
