New species of Lyonetiidae (Microlepidoptera). 



By Annette F. Braun, Cincinnati, Ohio. 



The types of these new species are in the writer's collection. 

 Paratypes of Bucculatrix errans and of Coptodisca negligens 

 will be placed in the collection of the Academy of Natural 

 Sciences of Philadelphia. 



BucculatriK fusicola n. sp. 



Head white, occasionally a few fuscous scales in the middle of the tuft; 

 antennae white, shading to pale fuscous toward the tips. 



Thorax and fore wings pure white, the wings marked with ocherous 

 streaks, which are sometimes slightly dusted with brown. There is a 

 median streak from base, often faint in the male; an oblique streak from 

 middle of costa, soon bending to become parallel with the median streak 

 (part near costa usually obsolete in female); a second, straight and less 

 oblique brownish costal streak passing across the wing and meeting on the 

 termen the end of a line of black scales which extends along the termen to 

 the apex; beyond the second costal streak a patch of slightly dusted ocher- 

 ous scales whose inner edge is parallel with the second costal streak and 

 nearer to it than the second is to the first costal streak; a faint ocherous 

 streak along the dorsum is deflexed beyond the middle and passes oblique'y 

 upward jommg the second costal streak; a line of black scales in the cilia 

 from apex to tornus diverges slightly from the line bordering termen. 

 Hind wings pale grayish ocherous in male, fuscous in female. 



Legs whitish, tips of tarsal segments spotted with black in female. Ex- 

 panse: 12 mm. 



Type ( 9 ) , reared from a spindle-shaped gall on stem of 

 Helianthus tracheliifolius at Cincinnati, Ohio; in addition to 

 the type, a large series of captured specimens, taken in patches 

 of this species of sunflower. 



The gall is usually situated toward the upper part of the 

 stem and averages about 2 cm. in length, with a greatest 

 diameter of .5 cm. The cavity in the gall within which the 

 larva feeds, is of about the same proportions. The larva 

 finishes eating in the latter part of September, but remains 

 in the gall throughout the winter, escaping in the spring 

 through a minute circular aperture. The cocoon is dark 

 brownish fuscous, smooth and flattened, and closely appressed 

 to the surface on which it is spun, resembling not at all the 

 usual Bticcidatrix cocoon. The imagoes appear from the end
