minute specks ; cheeks partly bordei-ed each side with pale green ; 

 rostrum pale greenish, short, black at base. Legs pale yellowish, 

 the inside and tip of posterior tibiae and bands on the tarsal joints 

 brown. Wing-covers smolce-fuscous, pale on the centre of all but 

 the apical cells ; costal border ivory-yellow, including two short 

 black stripes near its tip, following which the superior apical cell 

 is black, and the next below only a little less deep black, the inferior 

 one still paler, these three bounded on the sides by brown veins, 

 the other veins pale yellow ; areoles of the clavus each with a dark 

 brown stripe on the inner border ; wings faintly smoky, with dark 

 veins. Pronotum short, broadly curved in front, polished, 

 minutely wrinkled, marked anteriorly with a transverse series of 

 yellow dots, sometimes provided with five incomplete pale stripes ; 

 the dorsoluin bordered with a square yellow lineation, followed 

 directly behind by the triangular scutellum margined also with 

 yellow. Abdomen brownish or black, the segments generally 

 with pale edges, and the male usually darker than the female. 

 The superior genital j^ieces of the male nearly triangular, the 

 inferior ones uuitiug to form a longer subacuminate triangle 

 bordered with yellow; the valvular segment at base of these is 

 triangular and a little curved on the sides ; genital pieces all armed 

 with brownish long bristles. 



Length to tip of wing-covers 2i-3 mm. ; width of pronotum 

 1-1 1 mm. 



Five specimens of this odd little species were taken at various 

 places on the island. It is a common North- American 

 form which is distributed all the way from Florida, along the 

 coastal plain, to northern New Jersey. It varies much in depth 

 and extent of colour, and somewhat in the degree of bluutness of 

 the tip of vertex. In Maryland it rests upon the leaves of bushes 

 and occurs from August to October in sunny situations. 



Deltooephalus ouneatits, sp. nov. 



Eobust, brownish or black, marked with pale green above. 

 Form similar to the preceding species. Vertex bluntly rouuded, 

 a little longer than wide between the eyes, yellowish green, marked 

 anteriorly with two large black dots, aud farther back with two 

 minute ones ; eyes large, not prominent, but extending far back to 

 complete the deep sinus of the occiput ; front long, moderately 

 convex, with two broad stripes, which occupy most of the width 

 or are interrupted by oblique bands ; clypeus with a black dot each 

 side ; the rostrum short, fulvous. Pi*onotum very short, lenticular, 

 pale green, with an anterior impressed blackish submargin. 

 Hcutellum bluntly carinated on the middle, marked with black 

 before the middle, and twice indented there. Coxae mostly black ; 

 femora and tibiae dull testaceous, obscurely striped with brown, 

 the tarsal joints more or less marked with brown. Pleural seg- 

 ments blackish, partly marked with green ; wing-covers a little 

 curved on the costal margin ; the clavus pale green with a brown 

 edge on both margins, the costal area also green, this colour some-
