tnents narrowly edged with white and with a large black spot at the apex 

 of the last ventral segment. Length 4 mm. 



Valve of the male large, obtuse. Plates large, oval, tapering to a 

 slender point, much surpassed by the narrow pygofers. Last ventral seg- 

 ment of the female long at the middle, the outer angles retreating ; pygofers 

 slender, surpassed by the thick oviduct. 



Described from one female taken at Anglesea, N. J., on 

 July 1 6th by Prof. J. B. Smith, and three males captured near 

 New York City, by Mr. E. B. Southwick, on July 6th, and 

 August 12th, 1 89 1. In this species the female is more brightly 

 colored than the male with a pale transverse band on the pro- 

 notum, and the males when fresh have a large pruinose patch 

 on the middle of the costal margin as in Acinopterus acuminattts, 

 Xestocephalus tessellatus and a few other species of Jassidae. 



11. SCAPHOIDEUS LOBATUS, n. sp. 



Form of immistus nearly but with a shorter and broader vertex and 

 longer pronotum, elytra fulvous becoming deep brown on the clavus where 

 there is a lobate ivory-white commissural mark. Length 6 mm. 



Vertex a little over one half the length of the pronotum. Front pro- 

 portionately broader than in imiiiistus. Color greyish testaceous, whitish 

 above, Vertex faintly washed with brown omitting a white basal area; an- 

 terior edge white bordered behind by a wavy brown line ; anterior submar- 

 gin with a deep brown concentric line. Front pale brown with a few obso. 

 lete whitish arcs ; temples showing a brown dot and a brown cloud covers 

 the antennal depression and invades the cheek outwardly. Pronotum irro- 

 rated with brown, with three nearly obsolete longitudinal pale vittae. 

 Scutellum whitish with four brown marginal points, the basal angles fulvous. 

 Beneath whi'ish, faintly clouded and marked with brown on the incisures 

 of the connexivum. Tergum brown, the lateral margins and narrow edges 

 of the segments pale, Apical one half of the tarsal joints of the hind feet 

 and a row of dots at the base of the tibial spines, dark brown. Elytra 

 fulvous with the nervures and numerous irregular veiulets or pigment-lines, 

 more regular in the costal areole, dark brown ; disc of some of the areoles 

 and a cloud within the apex dark brown; clavus mostly ivory-white with a 

 large irregular fulvous-brown cloud resting on the suture and becoming 

 deep blackish-brown toward the pale commissural nervure where it is bis- 

 sinuate ; this, when the elytra are closed, leaves a white, more or less dis- 

 tinctly trilobate commissural mark which expands over the base of the clavus. 

 Wings smoky, iridescent, with fuscous nervures. Valve of the male small, 

 brown, Plates narrow, their slender recurved tips brown and fringed with 

 long white hairs. Last ventral segment of the female long on the middle, 

 its apical margin feebly sinuated and rapidly retreating either side, median 

 line feebly keeled, extreme tip brown ; pygofers brown, a little exceeded by 

 the oviduct and armed with numerous brown bristles.

 N. Y. and a number of examples of both sexes taken by Mr. E.
