VII, p. 78. 



This species is about the size of misclliis but with quite distinct reti- 

 culations on the clavus. Lergth 2.5-3 rmii- 



This was taken at Kittery June 26th, 1914, and the species does not 

 appear to be common or widely distributed in the state. 



Deltocephalus iufumatus n. sp. 



Small dark brownish or smokj' with light veins on the elj^ra. Length 

 ? 2.5 mm., c? 3 mm. 



Vertex rather broad subangulate and slightly conical in front, twice 

 as long at middle as next the eye and slightly broader than middle length. 

 Front broad, narrowing from below the antennae to base of clj'peus. 

 Qypeus distinctly narrowed at tip. lorae rather narrow and long bur 

 not reaching border of base, pronotum very short at sides ; scutellum 

 ver\- small ; elytra in female short, reaching only to base of pygof er, 

 apical cells very much reduced. 



Color: vertex, pronotum, except hind margin, scutellum, cross veins 

 and elytra mostly dull brown. The vertex with an indented transverse 

 double spot, scutellum with dark cross, elytra with whitish cross veins, 

 the costal and apical portion whitish. Legs with tibiae and spines brown- 

 ish, cheeks with brownish spot on the side, exterior border of face 

 brownish. 



Genitalia : Female last ventral segment scarcely longer than preceding, 

 hind border with shallow notches on either side of a narrow middle 

 tooth. Pygofer broad with short bristles at tip. ]\Iale — valve short, 

 broadly rounded or very faintly angulate at the middle. Plates broad, 

 rather short, margins upturned, disc polished, tips reaching scarcely to 

 tip of pygofer. 



Described from a number of specimens taken at Orono, ]\Iaine, July 

 3r<i, 9th, 191J. also taken at Orono, Houlton, Van Buren and Ft. Kent 

 in 1913. This species is about the size of obtectus, but has distinct mark- 

 ings and the soot}' black color is a distinction. 



This species agrees verj- closely ■\\-ith specimens I have from Edin- 

 burg, Scotland, which answer quite well the description of D. pulicaris 

 Fall.

 grass. Adults abundant July 28th. 29th. A few nymphs.
