"Allotype, winged female, Staten Island, N. Y., August 19, 1905. 



"Apterous male: Fusiform, pronotum tumid, divided by distinct 

 sutures into three segments; mesonotum with a deep suture behind 

 middle, directed anteriorly at each end; genital segment prominent; 

 abdominal segments subequal. Velvety gray black in color. 



"Long., 1.9 mm.; lat., .7 mm. 



"Morphotype: Apterous male, from Staten Island, same date. 



"Apterous female: Orbiculate, genital segment truncate; gray and 

 black coloring, much more marked and definite than in male. 



"Long., 1.6 mm.; lat., 1.1 mm. at widest part. 



"Morphoparatype : Apterous female, Staten Island, N. Y., June 3, 

 1905. Nine other paratypes of both sexes and forms from Westfield, 

 N. J., Yaphank, L. I., and Staten Island. 



"In all the underside of the head, pro- and mesosternum are yellowish, 

 as well as the coxae, trochanters and greater part of femora." 



Localities: New York, New Jersey, Kansas, Maine and Massa- 

 chusetts.

Champion, Biol, Centr. Am. Heter.. vol. II, p. 129. 



"Winged form. Male moderately elongate, narrow; black, a narrow 

 transverse line in front of the pronotum, and also the lateral margins 

 beneath, the rostrum, trochanters, and coxas, and the connexival margins, 

 flavous; the head with two posteriorly coalescent stripes between the 

 eyes, and the pronotum with an evanescent median line anteriorly, rufo- 

 fulvous; the elytra brown, with two long oblique streaks extending from 

 the base downwards, a long streak beyond these, a rounded spot near 

 the cost beyond the middle, and an oval spot at the apex, silvery-white; 

 the antennse brown, paler at the base; the legs brownish, with the femora 

 indeterminately flavous at the base; the body very finely and sparsely 

 pubescent, the costal margins of the elytra ciliate towards the base, the 

 under surface with a bluish-gray pruinosity; the antennse and legs pubes- 

 cent, the antennae also with some longer hairs. Antennae very slender, 

 not nearly so long as the body, joint 1 rather more than one-half longer 

 than 2, 2 short, 3 about twice as long as 2, very slender, 4 much longer 

 than 3. Pronotum rounded at the apex behind, with indications of a 

 faint mediam ridge. Elytra with rather feeble nervures. Legs very 

 slender, moderately long. 



"Length, 2% mm.; breadth, % mm." 



Bueno, in his Veliinae of Atlantic States, adds: 



"Apterous form: Connexivum strongly reflexed, with brown patch on 

 each segment; dorsum black, except three last abdominal segments, which 

 are broadly greenish, the last entirely so. Genital segment large, promi- 

 nent. Thorax tumid, mesothorax rounded behind; metathorax straight, 

 form narrow, abdomen subparallel. Male, Morphotype, male, Fort Lee 

 District, N. J., October 10, 1903. 



"Apterous female: Differs from the male in having the abdomen pos- 

 teriorly roundedly truncate; form obovate. The specimen in question 

 has the dorsum nearly entirely a deep velvety black; another specimen 

 shows but little black. Morphoparatypes, 2 females. Fort Lee District, 

 N. J., October 10, 1903; Fly Creek, N. Y., August 29, 1906. 



"In this species, as in the other, the most obvious character is in the 

 long, thin antennae. It cannot be mistaken for any other species, being 

 the largest of our eastern forms, except americana, from which its slim 

 body, long thin antennae and white-spangled hemelytra at once distinguish 

 it. The apterous are more glabrous and much less velvety in appearance 

 than the winged." 



Localities: New York, New Jersey, Maryland, Florida and Illinois.
