Tins genus is closely related to PInifomi/pIrra Roiulaiii (Xouvi .\iiiiali delie 
Seienze Xaturali di Bologna, ISdo, p. 13, Tav. 1, figs. 1, 2). Kondani’s figure 
shows the co.stal .setae only to the tip of the au.xiliary vein, in this genus they are 
equally prominent to the tij) of the first, and nearly as niarke<l to the tip of the .second 
longitudinal vein, one or two more consjiicuous setae are present before the junction 
of the au.xiliary vein. The first longitudinal rein is armed u'itli a large bristle towards 
the outer end, u'hile the third has two, on the notiecahlg thickened portion at the base. 
In other res|)ect.s it seems to resemble Rhiitumyptera, i. e . — in having the broad 
third antennal joint, and in the absence of the apical and po.sterior transver.se veins. 
The marginal macrochaetae on the second and third abdominal segments are small, 
there are also discal macrochaetae on the third segment. The latter are sometimes 
present in Phgtomi/ptera according to Braner and Bergenstamm, (Zweifliigler der 
Kaiser.ichen museums zu Wien, Pt. Ill, ]>p. 14S, 1.50, 1S03.). Macrochaetae on 
the fourth .segment large and numerous.

9 Head broad, face, front and occiput liluish-gray pollinose, frontal stripe red- 
dish brown, forked above and narrowly extending along the ocellar triangle, upper 
angle of the cheeks also reddish brown, facial depression deep, and ridge prominent; 
vibri.ssae large with numerous smaller biistles above and on the cheeks, frontal 
bristles descend to nearly opposite the second antennal joint, there are two pair of 
orbital bristles, and the ocellar bri.stles are directed forward; first and second joints 
of the antennae, brown, very short, the second setose, the third black, broad and 
obtusely truncate, arista black, jialpi brown. 
Thorax including the pleurae and .scutellum bluish gray |)ollinose, with two 
short, black, anterior, dorsal lines, and four [lostsutural and four sterno|)lcural macro- 
chaetae; scutellum bearing four jiair.s of marginal macrochaetae, two smaller bri.stles
