Description of New Species and Genera. 
1. Nippocallis n. g. 
Somewhat allied to Myzocallis Pass. 
Antennae much shorter than the body, the first and 2nd joints large and 
globose, the 3rd the longest, the 4th, 5th and 6th gradually decreasing in 
length, anterhinarial as long as and narrower than the postrhinarial, all the 
joints, except the 6th, with long erect bristles, each arising from a small 
tubercle ; frontal margin with long bristles, each arising from a tubercle ; 
pi onotum somewhat longer than the" head ; (brewings somewhat longer than 
the bod}', ample, stigma fusiform, the broadest part rather near the apex, 
media strongly curved, with 2 furcals, the first oblique perpendicular to the 
cubitus and far more separated from the 2nd oblique than the media is, stig- 
matic nervure absent, base of the media obsolete and where the cubitus strong- 
ly excurved, a large part along the veins strongly infuscated; hind wings 
with 2 obliques, the first nearly perpendicular to the cubitus, the 2nd some- 
what oblique, the part of the cubitus where the 2nd oblique opens is strongly 
incurved ; abdomen broad and roundish; cornicles short, rather large, as broad 
as the length ; cauda roundish, at the base constricted ; legs much broader than 
the antennae ; empodial hairs clavate, somewhat longer than the claws. 
Genotype — Nippocallis kuricola Mats. 
This genus may easily be distinguished from Myzocallis Pass, by the ab- 
sence of the sti<rmatic nervure to the fore-win<is. 
1. Nippocallis kuricola n. sp. (PI. XVII, f, s, a, b, c.) 
Winged viviparous female — Body yellowish brown (in alcohol), oval, to- 
wards the cauda broader ; antennae pale yellowish, much shorter than the 
body, the first 2 joint ; somewhat darker in color, the 3rd joint much the 
longest, with a few long hairs on the innerside, on the outerside with about 
6 roundish sensoria, the 4th subequal to the 5th, the 6th being the shortest, 
anterhinarial somewhat shorter than the postrhinarial, apices of the 3rd, 4th, 
5th and the middle of the 6th, infuscated ; front with some conical projec-
