166 A. A. Girault: ’ 
brown but the tarsi of the cephalic legs are yellowish; coxae con- 
colorous with the body. Posterior wings hyaline. Fore wings 
stained with brownish throughout but several distinct, rather 
large, oval elear spaces are defined. Venation and tegulae brown. 
Head, pro- and mesonotum densely punctate, the punctures round 
and sharply defined; metathorax with conspicuous longitudinal 
carinae and smaller and more numerous transverse ones, the former 
five in number counting the middle, median one which is com- 
pound, that is, at first consisting of a large cephalic half-portion 
shaped exactly like a lower case Greek letter Phi, then followed 
by a short median stalk, which supports a fork, the stalk and the 
fork resembling celosely the Greek letter gamma of the lower case. 
The next carinae, the true lateral carinae, are only regular at one 
place cephalad while the next at the lateral margin run only from 
the acute prolongation of the thorax. The outline of the five 
striae at the base of the second abdominal (first body) segment 
form a rectangle, which is longer than wide. The second abdominal 
segment distad, and the others are minutely, densely punctate 
and hairy. The coxae are similarly sculptured, or nearly. 
Ciliation of the disk of wings fine and normal, that of the 
caudal wings, however, not dense; caudal wings with marginal 
cilia along the caudal margin composed of short uniform eilia 
which are subcapitate. Extreme apex of posterior wing obtuse. 
Antennae regularly clavate, the club not differentiated 
distinetly. Scape long, subobclavate, as long as the combined 
jengths of the pedicel and first four funicle joints; pedicel longer 
than any of the funicle or club joints; funicle 1 wider than long; 
2 longest; 3 a fourth shorter than 2, over twice the length of 1; 
others shortening and widening distad; 4 and 5 subequal, slightly 
wider than long; 6 and 7 subequal, much wider than long; 8 or 
proximal club joint still slightly wider and shorter; distal club 
joint conical, twice the length of the preceding joint. Pubescence 
arranged in regular lines of which there are three on the distal 
club joint; no terminal spur on the latter.
