color; mesonotum evenly covered with testaceous yellow dusting and 

 with short appressed yellow hairs, except the bare and shining narrow 

 translucent posterior margin; on mesonotum only a trace of three 

 hnear vittae: one on median line and two lateral vittae on line of 

 dorsocentrals visible only from behind as a slightly darker color. 

 On hind part of mesonotum one pair of rounded black spots present, 

 each one between upper postalar and prescutellar bristles. The pleura 

 sparsely covered with ochraceous yellow dusting in front of mesopleural 

 bristles and bare and shining in their rear, with only one narrow stripe- 

 like dark spot on inferior margin of ventral pleurotergite, which in the 

 specimen examined is yellowish brown. 



Scutellum shining and translucent, ochraceous yellow, with some 

 sparse brown hairs on hind margin. Postscutellum without black 

 spots, slightly lighter than the brownish yellow, shining mediotergite. 



The yellowish brown thoracic bristles somewhat flattened; two 

 pairs of mesopleural bristles present, the lower one much weaker and 

 about half as long as upper one; dorsocentral pair placed almost 

 in suture; apical pair of scutellar bristles parallel. 



Coxae and legs ochraceous j^ellow, except the blackish brown disti-

Wings with characteristic pattern of the genus; it is characteristic 

 of the species that the remainder of basal band is concentrated, at 

 apical process of anal cell, in a small opaque blackish brown spot 

 which does not extend over anal vein. Stigma about 2.5 times as 

 long as wide basally. First costal section 0.45, second 1.07, third 0.68, 

 and fourth 0.41 mm. long; first section of the fourth longitudinal vein 

 1.04, penultimate 0.20, and very slightly arched ultimate 0.85 mm. 

 long; inner cross- vein (to) 0.24 and outer (tp) 0.39 mm. long; ta 

 slightly longer than distance between cross-veins, and more obliquely 

 situated than tp; penultunate section of fifth longitudinal vein, which 

 limits discoidal cell, slightly but distinctly excurved. Anal cell with 

 0.16-mm.-long apical process 0.52 mm. (whole anal cell 3.2 times as 

 long as the apical process). 



Preabdomen shining testaceous yellow, covered with brownish 

 yellow appressed hairs, 0.9 mm. long and 1.0 mm. wide, wider than 

 long; each one of third to fifth tergites marked with a pair of rounded 

 black spots; fifth tergite 0.33 mm. long, 1.5 times as long as fourth.
