Genus SCHIZELLA novum 



This new genus of the family Rhagionidse (Leptididse) is 

 erected for a small fly that shows the general appearance of 

 a Chrysopilus, differing in the form of the proboscis and chiefly 

 in the extraordinary development of the third antennal joint; 

 the latter character is noticeable because of the usual smallness 

 of the antennae in Chrysopilus. This elongated third joint is 

 besides divided into two branches, forming a fork, a thing not 

 rare in the family TabanidaB, but never observed in the Rhagio- 

 nidse. The terminal style, which is long in Chrysopilus, is rudi- 

 mentary in the new genus. 



The principal characters of the new genus are as follows: 

 Head as in Chrysopilus, but distinctly more transverse, facial 

 bulla greatly developed and produced below, palpi small; pro- 

 boscis with the terminal flaps much dilated, forming a sort of 

 blister as great as the facial one, minutely transversely rugulose. 

 Antennae with the two basal joints small and short; third joint 

 enormously developed, longer than the breadth of head, and di- 

 vided into two branches from the root; the upper branch is 

 a little shorter, but not narrower than the inferior one, which 

 bears at its end a short, almost rudimentary style (Plate I, fig. 1) . 

 Eyes of the female without a trace of division ; male unknown. 

 Thorax, abdomen, and legs as in Chrysopilus ; hind tibiae with 

 a single spur at end, the external one. Wings with the venation 

 exactly as in Chrysopilus; anal cell 'dosed and provided with a 

 short stalk. 



Type, Schizella furcicornis sp. nov. 



128.. Schizella furcicornis sp. nov. Plate I, fig. 1. 



A small dark reddish and brown species with pale legs and 

 grayish wings, which are a little spotted toward the middle. 



Female. — Length of body, 5 millimeters; of wing, 4.7; of an- 

 tennae, 1.2. Head black, gray-dusted on the occiput and on the 

 sides of the frons; facial bulla pale yellowish, white-dusted; 

 palpi blackish; proboscis with whitish flaps; antennae with the 

 two basal joints yellowish, the third brownish. Thorax dark 

 reddish brown, the pleurae paler and clothed with whitish dust; 

 it is entirely bare, even on metapleura, but it seems that on the 

 hind part there is a short pubescence, with metallic reflections.
