NEUROPTEROID INSECTS FROM SZECHWAJST BANKS 177 



palpi black; pronotum wholly black; mesonotum mostly black, but 

 some pale each side on scutellum; metanotum black in front and 

 middle, elsewhere pale; abdomen pale tawny above and below, also 

 cerci ; sternum pale ; legs largely pale, but hindlegs dark toward tips 

 of femora and above on the tibiae; wings pale gray, veins brown, 

 costal veins yellow. Head moderately broad, eyes large, ocelli form 

 an isosceles triangle, hind ocelli plainly nearer each other than to 

 eyes ; pronotmii much broader than long, somewhat narrowed behind, 

 a rather broad median furrow with the two ridges, lateral rugae 

 fairly large. 



Wings moderately slender; usually two branches to the radial sector 

 beyond anastomosis, about five costal cross veins beyond end of sub- 

 costa, first anal without curve, second only slightly curved, first anal 

 ends before origin of radial sector, latter rather far out, and about 

 as near to anastomosis as to first median cross vein, Male genitalia 

 very prominent ; the fifth segment much produced behind in a forked 

 lobe, each lobe with spinules, the upper branch of the process is very 

 long, horizontal, with a large hook at inner base, the inner edge 

 toward tip has several spinelike teeth, the first two rather large; 

 this process has many long, fine, erect hairs on inner side, the lower 

 branch of the process is slender and smooth and reaches fully to 

 the forked lobe of seventh segment. 



Length of f orewing, 14 mm. ; width, 4 mm. 



One male from Chengtu, May 10-11, 1,700 ft. In general appear- 

 ance it is similar to M. vitripennis. Holotype, U.S.N.M. No. 53140. 

 Paragnetina muUispinosa, lately described by Wu,^ is very similar, but 

 the process is differently armed.

Plate 27, FicrRES 3, 8, 9 



Pale brownish yellow; abdomen rather more yellow; wings pale 

 gray, veins brownish; apical half of cereal spine black; legs pale 

 yellowish, unmarked. The ocelli large and widely separated, the 

 eyes rather large, larger than in fratema; pronotum broader behind 

 than in front, the corners broadly rounded, posterior margin concave ; 

 fore wings long and slender, about 15 costal cross veins, four or five 

 beyond end of subcosta, about five median and five to seven cubital 

 cross veins, radial sector forked once, the pedicel nearly or fully as 

 long as fork, median is also forked once beyond the anastomosis, 

 branches from anal cell wide apart at base. In hindwings five to 

 eight costals and four or five beyond; radial sector and medius
