 ARCTIINJ;. 

 Genus KODIOSOMA, N. G. * Stretch. 



Head small, hairy, somewhat sunk in the thorax. Antennae moder- 

 ately long, pectinated. Palpi stout, very hairy, pendent, but very slightly 

 advanced beyond the front. Thorax broad and stout, very hairy as are 

 also the patagia. Abdomen stout, hairy, extending beyond the hind 

 wings, tufted at the tip and sides. Legs stout, smoothly scaled. Wings 

 subdiaphanous, thinly scaled, twice as long as broad, costa straight, 

 outer margin rounded, inner angle rounded; posterior wings two-thirds 

 as long as the anterior wings, not reaching to the tip of the abdomen. 

 Size small, color generally black. , 



This genus comes near to Phragmatobia. Having only unique speci- 

 mens of each of the four species enumerated, I am unable to give the 

 neuralion, as the small size of the insects precludes the possibility of 

 making it out without destroying the specimens. This meagre descrip- 

 tion must therefore stand until more material occurs. It is drawn up 

 from the typical species fulva and nigra; the other two species are re- 

 tained in the genus provisionally. 



l.-KODIOSOMA FULVA, N. S. (PI. 2, fig. 7.) 



Head black, hair}'. Palpi stout, black, tips paler, hairy, pendent, 

 scarcely visible beyond the front. Antennae black. Prothorax hairy, 

 pale buff. Patagia long, narrow, clothed with long fine black hairs, 

 as is also the thorax. Legs long, slender, black inside, white outside. 

 Abdomen stout, broad, depressed, clothed with long silky black hairs 

 above, slightly mingled with buff. Tip prominently buff; beneath paler. 



Anterior wings long, narrow; costa straight, slightly rounded at tip; 

 outer margin rounded, nearly equal in length to the inner margin; 

 inner margin straight, nearly parallel with the costa. Color smoky 

 black, subdiaphanous, thinly scaled, with the base and margins of the 

 wing slightly darker than the disc. Costa margined narrowly with buff.
