PARAMADIZA new genus. 



Front below the ocelli quadrate, one third broader than long; 

 ocellar triangle large, reaching nearly to the frontal suture, before 

 its apex a single pair of cruciate bristles; four fronto-orbital bristles, 

 the lower two convergent, the upper two divergent ; postverticals 

 approximate and parallel, strong; frontal suture transversely bisin- 

 uate. Face nearly vertical, with two large deep subantennal depres- 

 sions and strongly carinate medially, the epistome slightly projecting. 

 Cheeks one fourth the eye-height, the vibrissa! angle rounded-rectan- 

 gular; occiput obliquely descending to the vibrissal angle, its ridge 

 with a row of strong bristles ; two strong and one weak vibrissse along 

 the front of the small bucca; eyes rounded, longest vertically. An- 

 tennae small, reaching two thirds the distance to the oral margin, the 

 arista about twice the length of the orbicular third joint, bare. Pro- 

 boscis short, fleshy; the palpi clavate. Two humeral bristles; two 

 notopleural, one presutural, two supra-alars, one intra-alar, three 

 dorsocentrals in back and one in front of the suture, acrostichals 

 sparse, four scutellars; one sternopleural, one lower and one postero- 

 superior mesopleural in addition to the setulse, no prothoracic bristles. 

 Scutellum subtriangular, flat, bare. Abdomen with five segments plus 

 the ovipositor, with sparse setulae. Legs moderately stout, front 

 femora bristly, posterior tibiae with small apical spurs, but not at all 

 compressed; pulvilli small. Calypteres rudimentary, bare. Costa con- 

 tinuing to the fourth vein, broken beyond the humeral crossvein and 

 before the end of the first vein, at the latter place with two stout 

 bristles and at the humeral break with one similar bristle, base of the 

 costa with two long and strong bristles, costa otherwise not bristly; 

 third vein diverging from the second so as to end at the wing tip; 

 discal cell long, posterior crossvein beyond the middle of the wing 

 and anterior crossvein much beyond the second costal break, the 

 penultimate section of the fourth vein nearly one half as long as the 

 ultimate section and longer than the ultimate section of the fifth vein; 

 basal cells small but evident, the anal vein reaching half way to the 

 margin.
