cornuti. Transtilla a large rectangular plate, produced anteriorly 

 at middle, with well-developed hairy lobes, the latter fused. Socii 

 large fleshy, hairy flaps. 



Female genitaUa. — Genital plate broad. Ostium a long transverse 

 slit. Posterior two-fifths of ductus bursae sclerotized, straight; a 

 small protuberance from the side of the sclerotized portion of the 

 ductus bursae; inception of ductus seminalis just before ostium. 

 Bursa copulatrix small with well developed signum in the anterior 

 end.

Remarks. — The number of cornuti on the vesica seems to be of no 

 significance in this species. Such differences in the number of cornuti 

 are usually specific but in the present case all intergrades may be 

 found in any one group of specimens. It is also rather strange that 

 cinereocostella should feed on so many species of plants, a habit which 

 is unusual for species of this genus. The specimens reared from the 

 different food plants exhibit no characters by which any one group 

 can be separated from another. 



This species is of some economic importance. Although it has not 

 done great damage to crops of caraway, it is potentially dangerous 

 because of its unusual habit of feeding on a number of food plants.
