2. S. intricatus. New sp. 



Form of 8. immistus, ivory white or yellowish, with the 

 interior margin of the head more thickened than in that species, 

 and the submargiu destitute of the slender line ; vertex con- 

 spicuously white, with a diagonal pale brown callous streak 

 over the antennae ; front obsoletely striated above ; antennae 

 piceous, testaceous at base. Pronotum with a few indistinct 

 brown points across the anterior portion, and some cloudy spots 

 near the base. Scutellum pale yellow, with a brown spot, or 

 spots, on the basal part of the disk, but sometimes without 

 spots. Beneath and legs white, the tarsal nails black, posterior 

 tibiae brown at tip and with black dots at the base of the spines, 

 a wide black band covers the middle joint of posterior tarsi. 

 Wing-covers whitish hyaline, with a large fulvous spot on the 

 middle of the clavus, on which is placed a diagonal large brown 

 comma ; on the corium, exterior to these, is a large irregular 

 dark brown, double streak, followed behind by a white spot, 

 next the nodus is a cuneiform dark brown spot, connected with 

 the brown veins of the discal and apical areoles, the two areoles 

 next behind this white, followed by a broad fulvous patch across 

 most of the membrane, the apex with a large dark brown spot 

 next the white apical margin. 



Length to end of abdomen 5 millims ; to tip of wing-covers 

 5J— 6 millims. Width of pronotum l|^-lf millims. 



This has hitherto appeared as a more uncommon species than 

 any one of the others here enumerated. It lives on Crataegus 

 bushes, and may be obtained in the adult stage from the early 

 part of August until the middle of October, in sheltered places. 

 I have taken specimens in the Piedmont region of Maryland 

 and Virginia in September and October, and on the Atlantic 

 Coastal plain in Maryland and New Jersey in August. The 

 ivory white color of the head and pronotum contrasting with 

 the chestnut brown markings of the wing-covers gives it a very 

 conspicuous and attractive appearance during life. It has 

 occurred to me only in single specimens at a time on the bushes 

 which it inhabits. 



3. S.juGundus. New sp. 



A beautiful tawny-yellow species, with semi-transparent wing- 

 covers having a tinge of yellow, especially near the inner and
