17. STREPSICRATES Meyrick 

 (Phthinolophus Dyar, Eucosma, in part, Walsingham and Durrant) 



Palpi rather clavate, scaled, with prominent short porrect third joint. Thorax 

 smooth. Fore wing with outer margin rounded, the cell with a heavy scale-tuft 

 in fold at one-third way out. Costal fold of male very large. Hind wing with 

 HI. markedly sepai'ate from M :! and Cu t which are stalked, R and Mj approximate. 

 Male antenna? with basal segments of shaft more or less fused and distorted, 

 about the sixth to tenth joints forming a notch, partly covered by a scale tuft. 



Male genitalia similar to those of Spilonota. Pollex present ; anal angle spinulose ; 

 cucullus with several marginal spines. Socii small and slender. 



1. S. indentanus Dyar. Normally with costal two-thirds of wing brown, quite 

 variable in shade, and the dor al third paler gray, often contrastingly pale, especially 

 in males; the boundary wavy and more or less denned with black. Hind wing 

 mouse gray. 12 mm. 



July. Larva a leaf roller on Myrica. The Florida species on guava appears to 

 be distinct. 



Canada to Florida. "New York" (American Museum of Natural History). 



18. SONIA Heinrich 



(Eucosma, in part) 



Fore wing with costal fold present in male. R 4 and R-, completely united; oiiter 

 margin concave, with M. to Cu t approximated; Cu 2 straight; R., arising near R. from 

 the normal accessory cell; R t from before middle of cell. Hind wing with R and M, 

 often anastomosing and sometimes stalked. 



Male genitalia similar to those of Siileima; clasper rudimentary; socii short 

 and broad. 



Ths single species is almost identical in pattern with E. perplexana Fernald, 

 from the Gulf strip, but the latter has R 4 and R- separate. 



1. S. constrictana Zeller. Ground light brown-gray; when fresh, with distinct 

 violet iridescence; markings dee]) brown. Base deep brown; antemedial line per- 

 pendicular to inner margin, except toward the costa where it often fades out; 

 straight or slightly excurved below cell; an irregularly quadrangular dark brown 

 patch on inner margin toward anal angle, with its upper boundary oblique and 

 parallel to the lower boundary of a similar patch over end of cell; typically with 

 the two patches fused, and the point of fusion marked by a strong notch on tin 

 anterior side of the combined patch, at the fold; postmedial patch on cell sharply 

 defined on basal and lower sides, but above shading into a brown outer costal 

 shade, which surrounds the upper sides of the speculum; costa with pale paired 

 strise outwardly; speculum blue-gray with some brown in center. Fringe powdery. 

 12—15 mm. 



June to August. 



Northern New Jersey to Florida, west to South Dakota and Texas. 



19. SULEIMA Heinrich 

 (Thiodia. Semasia, in part) 



Similar to Sonia. R 3 arising from middle of cell or slightly beyond; costal fold 

 absent; notch on outer margin variable. Hind wing with R and M t always stalked, 

 M 3 lost. Clasper absent. 



1. S. helianthana Riley. Whitish gra\ . Fore wing with two quadrate blackish 

 patches on inner margin, and a black dash and white triangle at the apex. Base
