Fig. 15. — Penthetria fragmentum, Handlirsch. 

 A portion 7™° long from the middle of a wing about 11""" in 

 length, the form of which was apparently rather elliptical; its 

 breadth and length were about in the proportion of 1:2-8. The 

 radius is nearly straight, and appears to extend somewhat beyond 

 seven-tenths the length of the wing. The sector arises immediately 

 posterior to the first third of the length of the wing and is distinctly 

 arcuate. The radiomedial cross-vein is situated about the middle of 

 the length of the wing and also midway between the origin and 

 bifurcation of the sector. Quite a distance distally beyond the centre 

 of the wing, the media divides into two apparently widely divergent 

 branches. The moderately curved posterior branch of the cubitus 

 reaches beyond half the length of the wing, while the anterior branch 

 is remarkably straight. The mediocubital cross-vein is situated 

 twice as far above the radiomedial cross-vein as is the latter anterior 

 to the bifurcation of the media. The first anal vein is nearly paraPel 

 with the cubitus.
