 Chrysopa maculipennis, White, Eyres Travels, Appendix. 



Subcostal and! marginal veinlets much like those of O. cliry- 

 sops ; many transverse veins between the radial vein and the sub- 

 costal vein ; space between the second sector and the radial vein 

 much broader ; areolets of the disk mostly quadrilateral and trans- 

 verse : prothorax subcylindrical, tapering from the mesothorax to the 

 head ; its length about thrice its breadth.

3. OSMYLUS VALIDUS. 



Piceus, crassus ; prothorax linearis ; pedes ferruginei ; alee cinc- 

 rece, anticce fusco signata, marginibus albo maculatis. 



Subcostal veinlets much like those of O. chrysops ; space be- 

 tween the second sector and the radius much narrower ; its veinlets 

 much less numerous : marginal veinlets more numerous, more ob- 

 lique towards the base in all the wings. In the hind-wings the 

 space between the second sector and the radius is broader, and the 

 space between the two sectors has much fewer transverse veinlets ; 

 the gradate veinlets in the disk on all the wings form only one series, 

 whereas they form two and more in O. maculatus. Body pitchy, 

 stout, pubescent : head very little broader than the prothorax, which 

 is hairy, linear, and much broader than long: legs ferruginous: 

 wings gray : fore-wings with very numerous brown marks which are 

 most prevalent about the margin, along which are some whitish 

 spots; the largest brown spot on the gradate veinlets below the 

 middle: hind-wings with some slight whitish and brown marks 

 along the border: veins black, with whitish bands. Length of the 

 body 710 lines ; of the wings 2328 lines.
