NEUROPTERA— TEKMITINA. 109 



again as any other part of the body, in length just about equaling the en- 

 tire thorax. Abdominal appendages obscurely seen in a single individual,;- , 

 where they are tolerably stout, tapering slightly, very bluntly terminated, fj;^ *" ' 

 and about as long as the last abdominal segment. Legs very short, the '• 

 tibisB being shorter than the width of the thorax, and armed at tip with a v^ 

 pair of short straight spurs ; tarsi not more than half as long as the tibiffi, 

 but the separate joints are not determinable on any of the specimens. 



Wings four times as long as broad, the middle of the front pair reaching 

 the end of the abdomen, long and very regularly obovate, the only differ- 

 ence in the form of the two extremities being in the gentler tapering of the 

 base and the straighter course of the costal margin next the base. The 

 basal scale is triangular, about as long as the mesonotum, its costal and 

 outer margins each a very little convex. The scapular vein, its superior 

 branches, and the mediastinal are stout, while the other veins are very 

 feeble and only appear under favorable preservation. The submarginal 

 vein ^ is crowded against the margin, but does not run fairly into it before 

 the end of the basal fifth of the wing. The mediastinal vein terminates a 

 short distance before the middle of the wing. The scapular vein runs at 

 only a short distance from and parallel to the margin, and emits from five 

 to eight superior branches running in an extremely longitudinal course to 

 the costa ; usually the first branch is thrown off almost as far out as the 

 middle of the second quarter of the wing, but where the branches are 

 numerous three branches are thrown off before the middle of the wing ; in 

 addition to the superior veins two inferior veins are emitted in the apical 

 third of the wing, and strike the lower margin of the wing just below the 

 apex. The externomedian vein runs subparallel to, but a little divergent 

 from, the scapular, and nearly as far from it as it is from the costal margin, 

 emitting four inferior simple or forked branches which cover the greater 

 part of the hind bord,er with their ner^ules ; from near the middle of the 

 wing a superior branch is also emitted, which is soon lost. The interno- 

 median vein is forked, and strikes the margin near the middle of the basal 

 half. 



Although in the number of branches to the scapular vein the speci- 

 men showing the wings most clearly (No. 7752) differs considerably from 



' What I here call the submarginal vein is the short .simple vein, sonietinies present in, at other 

 times absent from, Termitiua, which precedes the mediastinal vein. Hagen calls it the first branch of 

 bis sabcosta.
