TWO NEW SPECIES OF JASSID.^.. 



BY HERBERT OSBORN, OHIO STATE UNIVERSITY, COLUMBUS. 



Deltocephalus apicatus, n. sp. — Head and pronotum yellow; scutel- 

 lum and elytra reddish fuscous, the latter with hyaline apex. Length to 

 tip of elytra, $ and ,^ , 3 mm. 



Vertex about as long as width between the eyes, margin rounded, 

 apex prominent; front with sides nearly parallel to below the antennse, 

 then curving sharply to the base of the clypeus ; clypeus slightly 

 narrowed to tip. Pronotum, width more than twice the length, lateral 

 margin short, posterior margin straight. Elytra passing the abdomen, 

 with fully formed apical areoles (macropterous), or reaching only to tip of 

 abdomen, with the apical areoles very much abbreviated. 



Colour : Vertex, face and most of the pronotum yellow ; ocelli black ; 

 very faint whitish parallel lines on the posterior part of the vertex, and in 

 some specimens faint arcs on the front ; three whitish lines on the 

 pronotum ; more or less of posterior part of pronotum, all of scutellum, 

 and the elytra as far as the apical transverse veins, reddish brown or 

 fuscous, fading apically to hyaline or with all the apical areoles hyaline. 

 Beneath, sordid yellow, with the venter washed with fuscous. 



Genitalia: Ultimate ventral segment of the ? moderately long, 

 the lateral border sloping, the hind border slightly bisinuate and with a 

 spot each side of middle extending on to disk and giving a trilobate 

 appearance to the border ; pygofers nearly reaching tip of ovipositor, 

 thickly set with bristles on posterior half. $ valve rather long, anterior 

 border strongly curved and posterior border evenly rounded ; plates long, 

 nearly reaching tip of pygofers, contracting sharply from base to middle, 

 then tapering uniformly to narrow tip ; pygofers thick, white, thickly set 

 with short bristles. 



Described from eleven specimens, four 9 s and seven $ s, represent- 

 ing localities as follows in Eastern U. S.: i, Md. (Mally) ; i, Riverton, 

 N. J. (Johnson) ; i, Hyattesville, Md. (Hine) ; 2, Washington, D. C. 

 (Hine): 3, Woodstock, Vt.; and 2, College Park, Md. (Ball). 



This is a very characteristic little species, and shows a distinct 

 dimorphism in a form with shorter elytra with imperfect apical areoles. 



Paramesiis furcatus, n. sp. — Beautiful golden yellow, with milky 

 hyaline spots on elytra. Median lobe of ventral segment furcate. 

 Female length to tip of elytra, 7 mm. 



Vertex smooth, slightly depressed behind sharp anterior margin,
