PCECILOPTERA. 311 



Fam. 



Wings with tine^form structure. Hind wings with the 

 costal nervure straight ; with the subcostal si'mple, attenuated 

 interiorly to the discal, but joining the costal near its basal third. 

 Discal vein nearly straight, ivith two disco-central nervules. 

 Median with three equidistant branches. 



Fore wings with the disk extending beyond the apical 

 third of the wing. About the middle of the disk the sub- 

 costal vein sends off a strong marginal branch, beyond which 

 is a secondary cell, from the hinder end of which arise two 

 marginal and an apical branch ; discal vein nearly straight, 

 with three disco-central branches; median S-branched, the 

 posterior very remote from its penultimate; the fold is 

 thickened and the subcostal is forked at its base. 



PCECILOPTERA Clemens. 



The wings are longer than the body. The anterior rather nar- 

 row, enveloping the body when folded ; apex obtusely rounded and 

 hind margin slightly oblique. The subcostal nervule gives rise to 

 a marginal nervule, about its middle, and within the disk forms a 

 large secondary cell, from the hind end of which arise three dis- 

 tinct marginal nervules, the lower one reaching the costa rather 

 above the tip. The disk extends rather beyond the apical third 

 of the wing, and the discal vein gives rise to three nervules. The 

 median is 3-branched, the posterior branch being remote from the 

 others and arising opposite the origin of the subcostal branch, 

 which forms the secondary cell. The fold is thickened, and the 

 submedian furcate at its base. The hind wings are rather broader 

 than the fore wings ; obliquely rounded along the hind margin 

 from the tip to the base; costa nearly straight. The costal nervure 

 distinct and simple ; the subcostal simple and rather attenuated 

 from the discal vein towards the base. The discal vein gives rise 

 to two nervules, and sends a false nervule through the disk towards 

 the base of the wing. The median subdivides into three equi- 

 distant nervules. 



Head rather small, smooth, free ; without ocelli. Face rather
