Dec, 1903.] New Species of Ohio Fulgoridae. 45 



tibiae, dull black ; hind tibiae, fuscous, indistinctly annulated with yellow- 

 ish; tibial spur and first and second joints of tarsus, j-ellowish white. Third 

 joint of tarsus and claws, black. 



BrachypteroKS, male. Color as in the female, but the black of 

 €l3'tra and head more intense and white a purer white. I^ength, 

 2.3 mm. 



Structural characters of the body as in the female, the difference lying in 

 the size and the intensity of the color marking. The tibiae slightly more 

 dilated. 



Genitalia. Pj-gofer excavated ventrally ; styles narrow, nearh' parallel, 

 slightly curved dorsally. 



Macroptcro2ts, inalc. Black with the white bars on the vertex 

 and front and tip of scuteHum faintly white. Length to tip of 

 elytra, 3.2 mm. 



Head as in brachypterous forms, the carinae of the vertex apparenth- a 

 little stronger. The hind border of pronotuni broadly sinuate. Scutellum 

 larger, broader than in the brachypterous form, with the posterior lateral 

 margins concave. Ehtral neuration strong, veins tuberculate, having short 

 setae. Almost entirely black. Differs from the brachypterous form in not 

 having white on pronotuni and scutellum. \'ertex barely shows traces of 

 white margin, front has the transverse bars and lateral spots distinct, with 

 apical border distinct but narrow ; tip of scutellum is faintly whitish ; the 

 antennae are brownish ; the apex of the first joint, black ; femora, yellowish 

 brown ; anterior and middle tibiae, black ; tip of tibiae and first and second 

 tarsal joints, white ; hind legs mostly brownish ; tips of sj^ines and claws, 

 black. 



Macroptcroiis, foil ale. Black with margins of vertex in front 

 and tarsal joints white, as in the brachypterous forms. 



Elytra hyaline with a fuscous spot at vertex of clavus. This form agrees 

 with the macropterous male, except that the hind border of the pronotuni is 

 more broadly whitened. While markings of the vertex more distinct near 

 the apex. The color as a whole somewhat less intensely black. A single 

 specimen of this form, which must evidently be associated with the preced- 

 ing. 



Described from two brachypterous females, two brach3-2Dter- 

 ous males, and one macropterous male, collected in Columbus, O., 

 by Mr. Albert Koebele, September, 1903- One macropterous 

 female collected in "D. C," May. 



This is one of the most elegant Delphacids which has 3'et come 

 to light in Ohio fatuia, and I take special p^eastire in dedicating 

 it to my friend, Mr. Albert Koebele, who collected these and a 

 number of other interesting fulgorids here the past summer. 



It resembles nervatus but differs particularly in the white tar- 

 sal joints and in the extent of the frontal bars, and in the color- 

 ing of the pronotum and i-cutellum.
