LeptaniJla santschii new species 
$ Length — 1.2 mm. 
Head large, about one-sixth the entire length of the 
body, one and four-fifths times as long as wide, somewhat 
narrowed behind. 
Eyes large, protruding, diameter about one-third the 
length of the head, situated far forward, hairy, posterior 
margin slightly emarginate. Median ocellus oval, the others 
rounded and placed near the vertex. 
Antennse thirteen-jointed, little more than one-half the 
length of the body. Insertions twice as far apart as the 
distance from the eye, and situated close to the mouth. 
First segment almost one-third as wide as long; second 
and third each, nearly one-half the length of the first; 
fourth to twelfth, one-third longer than wide; last joint, 
slightly longer than the first and about one-half as wide. 
Mandibles minute. Palpi prominent, single jointed. 
Frontal carinse and clypeus indistinct. 
Thorax compressed laterally, thinner above than below, 
depressed at mesoscutellum ; measuring one-third the entire 
length of the body, one-half again as long as deep, four- 
fifths as wide in dorsal view as the head. Epinotum rounded. 
Anterior legs very thick; mesothoracic legs shorter and 
more slender than the others. Femora thick. Mesothoracic 
tibia with one spur, metathoracic with two. Hind legs 
extending beyond the end of the abdomen. 
Fore wing two and one-half times as long as its greatest 
width, which is at one-third the length from the apex. 
Costal vein and a cross-vein near the base very faintly 
suggested. 
Hind wing ten times as long as its greatest width, which 
is near the middle, and two-thirds as long as the fore wing. 
Abdomen one-third the length of the body and two-thirds 
the width of the head, rather straight to the sixth segment, 
which turns downward abruptly, so that the genitalia are 
at right angles to the rest of the abdomen. Genitalia one- 
sixth the length of the body. Node one and one-half times 
as long as high. Pedicel very short. 
Genitalia conspicuous and probably non-retractile. 
Sagittse rather thick, bent forward at the tip, slightly longer
