64 STUDIES IN NORTH AMERICAN MEMBRACID/E 



- Humeral angles not produced for more than the length of 

 the eye; pronotum strongly banded but without the black 

 spot, 15, unicolor Fh. male. 



16. Crest with an obvious sinus at its anterior base; posterior 

 sinus without a pale vitta, 15, unicolor Fh. female. 



-. Crest vertical or a little overhanging before, without a dis- 

 tinct sinus at its anterior base; posterior sinus with a 

 white vitta, 16, cxtrema Ball. 



1. Telamona declivata n. sp. 



Intermediate between Giossonotus, Heliria and Telamona. Prono- 

 tum low, slender; crest placed behind the humeri, narrow, nearly vertical 

 before, anterior angle rounded, superior margin sloping backward rather 

 steeply, the hind angle forming a decided break, sometimes a small step, 

 at about the middle of its posterior declivity; posterior process long and 

 slender, its acute apex a little exceeding the tip of the elytra. Pronotum 

 coarsely punctured with moderately distinct rugse posteriorly. Color dull 

 yellowish brown with a dark nearly vertical vitta from the middle of the 

 lateral margin, widening upward and covering the entire crest and spread- 

 ing faintly down over the middle of the metopidium ; apex broadly brown 

 irrorated with pale; between the brown bands is a broad pale vitta on which 

 is a median black mark on the carina. This pale vitta is extended upward 

 along the carina to the posterior angle of the crest. Elytra nearly hyaline, 

 the apical fuscous vitta narrow, not extending forward of the costal margin 

 of the terminal areole. Median pale carina varied with black on the meto- 

 pidium and there is a black point on the anterior margin of the metopidium 

 above each eye. Face pale. Beneath pale varied with brown. Length 

 9-10 mm. 



Described from four females. Two of these I took at 

 Milan, Ohio, on September 1st, 1905; one was taken in New 

 Jersey by Mr. W. T. Davis, and one from Ithaca, N. Y., is in 

 the Cornell University collection. The specimen from New 

 Jersey has the crest distinctly inclined forward while that from 

 Ithaca has the hind angle of the crest produced in a distinct 

 "step" similar to that found in Heliria, to which genus this 

 species is further allied by its prominent humeral angles. I 

 have tried to identify this with Goding's Heliria Strombcrgi 

 but his description of the crest is quite unintelligible to me. It 

 is just possible that Telamona barbata, described below, may 

 be the male of this but I cannot so place it now. 



2. Telamona pyramidata Uhler. 



This is a slender species recalling Glossonotus. The pro- 

 notum is similarly elevated and is marked with the same white
