6. OSMYLUS LONGIPENNIS. 



Piceus ; prothorax linearis ; pedes testacei^fasciis tarsisque piceis ; 

 alee cinerascentes, longissimce, anticce fusco guttatce. 



Subcostal veinlets much more numerous than in O. chrysops, 

 and more contiguous towards the base ; veinlets of the sector of the 

 second radius also much more numerous ; gradate veinlets forming 

 many more series ; veins more oblique towards the tips ; marginal 

 veinlets much more numerous ; areolets in the disk much more 

 numerous, more alike and regular in form, generally almost square. 

 Pitchy : prothorax linear, longer than that of O. chrysops, and not 

 narrower in front as is the latter : legs testaceous, with pitchy 

 bands: tarsi pitchy: wings grayish, very long; fore-wings very 

 thickly covered with brown dots, many of which are confluent ; 

 veins brown. Length of the body 5 lines ; of the wings 30 lines.

7. OSMYLUS TUBERCULATUS. 



Testaceus, fusco varius ; antennis pedibusque flavis ; alee hyalince, 

 venis albidis fusco variis, venulis nonnullis transversis fusco 

 nebulosis, stiymate flavescente ; tubercula una fusca ftavo vit- 

 tata in alee anticce margine postico. 



Structure of the wings like that of O. chrysops : transverse 

 veins of the fore-wings less numerous. Testaceous, with brown

8. OSMYLUS LONGICOBNIS. 



Testaceus, fusco subnotatus ; antenna straminece^ pubescentes, gra- 

 cillimce, alls multo longiores ; pedes stmminei ; alee hyalince, 

 angustae, antice fusco notatce, venis albidis fusco variis. 



Allied to O. chrysops: distinguished from all the other species 

 of Osmylus by its very long antennae, and by the marginal region 

 which is almost equal in breadth along most of the length, and is 

 narrower towards the tip than that of O. chrysops ; areolets and
