of the sooty spot*. Posterior wings iiyaline. Tegulse neutral. Eyes 

 dark reddish ; ocelli the same color. Outer teeth of mandibles fuscous. 

 Sculpture of body not conspicuous. Eye with sparse hairs, subreui- 

 form or rounded with its caudo-lateral margin concave, their surface 

 coarse, much coarser than the fine longitudinal striation of the thoracic 

 nota and pleura or the the transverse striation of the vertex, that of 

 the occiput and face ; abdomen with fine polygonal sculpture. Ocelli 

 in a nearly equilateral triangle in the center of the vertex near the 

 occipital margin, the lateral ones distant from the eyes, the distance 

 between them being slightly greater than the distance between each 

 and its respective eye margin. Fore wing narrowed, at least four times 

 as long as its greatest width, widest just before its apex, the latter 

 rounded, the whole wing spatulate in shape, not linear but narrower 

 than that of the species aniericana ; discal cilia of the fore wing ap- 

 parently absent but (high power) in the distal half of the blade, beyond 

 the fumated spot, a similar longitudinal line on each side, the caudal 

 line longer, the cephalic line containing about six or seven cilia all 

 widely separated in the line and a few irregularly placed similar cilia 

 distad ; the usual line of cilia arising on the disk of the wing from 

 nearly between the bases of the marginal cilia, disappears, after round- 

 ing the apex of the wing from the cephalic margin, at the distal end of 

 the caudal margin. Marginal cilia of fore wing long, dark, most con- 

 spicuous and longest at the wing apex where they are about equal in 

 length to the greatest width of the wing. Marginal and submarginal 

 veins linear, the latter slightly longer than the former ; postmarginal 

 vein absent ; stigmal vein very short. The marginal vein proper bears 

 four large setae from its surface. Posterior wing naked discally, with 

 the exception of the faintly indicated longitudinal line along the cephalic 

 wing margin ; its venation narrow and continuous ; its blade portion 

 linear with an obtusely pointed apex and the marginal cilia short on 

 the cephalic margin but long conspicuous and dark on the caudal mar- 

 gin, especially distad ; here they are nearly three times as long as the 

 wing is wide but not as long as the longest marginal cilia of the fore 

 wing. 



Thorax and abdomen normal, the parapsidal furrows complete; ovi- 

 positor not exserted. Legs normal ; proximal tarsal joints lengthened 

 somewhat, not quite equal in length to the two distal joints combined ; 

 the intermediate tarsal joint a fourth longer than the distal joint which 

 is about a third shorter than the proximal joint. Abdomen conic- 

 ovate, obliquely truncate caudad, nearly as long as the head and 

 thorax combined. Mandibles apparently 3-dentate, the two outer, 

 lateral teeth strong, dark, acute. 



Antennae (fig. 1) 7-jointed— scape, pedical, single ring-joint, single 



* More pronounced in some specimens than in others, being nearly 

 invisible in many.
