Teleorhinus Uhler. 

 T. tephrosicola Knight, new species. 



Male: Length 7.3 mm., width 2.2 mm.; differs from cyaneus 

 Uhler in that the combined length of antennal segments iii and 

 iv is greater than the length of segment ii ; clavate portion 

 of segment ii only twice as thick as segment i, while in cyaneus the 

 apical half of segment ii is three times the thickness of segment i. 



Antennae : Segment i, length .36 mm., black ; ii, 2.05 mm., 

 apical two-fifths clavate, .17 mm. thick, yellowish, the clavate por- 

 tion black; iii, 1.39mm., slender, fuscous, slightly paler at base; 

 iv, .97 mm., fuscous. 



Black, shining, minutely pubescent, very similar to cyaneus but 

 differs in form of anterior angles of pronotum ; legs pale reddish 

 yellow, coxae whitish but blackish at base ; rostrum brownish but 

 darker at base and apex. 



Female: Length 7.6 mm., width 2.5 mm.; not differing 

 materially in form or color from the male. 



Holotype: Male, 11 July, 1916, Yaphank, Long Island, N. Y. (.Wm. T. 

 Davis ) ; author's collection. Allotype : taken with the type. Paratype : 

 Female, 17 June, 1906, Lakehurst, N. J. (Wm. T. Davis). Mr. Davis took 

 the type specimens on flowers of Tephrosia sp. 



Subfamily Dicyphinae. 



Key to Genera. 



1. Pseudarolia prominent (fig. 49 : 18-20) 2 



Pseudarolia absent (fig. 49: 21) ; hemelytra hyaline, glassy, ovate, 



with a sharply defined inverted Y-shaped red or fuscous mark 



(p. 478) Hyaliodes 



2. Calli distinctly impressed at basal margin, and thus the pronotal 



disk rather distinctly transversely sulcate (p. 476) Dicyphus 



Calli not or scarcely impressed at basal margin, pronotal disk not 

 transversely sulcate 3 



3. Eyes small, head elongated behind eyes for a space equal to 



lateral width of an eye (p. 478) Macrolophus 



Eyes large, head space behind eyes not equal to half the lateral 

 width of an eye [Cyrtopeltis] 



Dicyphus Uhler. 



Key to Species. 



1. Ostiolar peritreme strongly protruding, ostiole large and clearly 



exposed 2 



Ostiolar peritreme scarcely raised from the pleural wall, ostiole 

 inconspicuous or quite concealed ; head and pronotum black, collar 

 and ray between calli pale, hemelytra chiefly pale agilis 



2. Eyes removed from pronotal collar for a space equal to dorsal 



width of an eye ; hemelytra conspicuously colored with red 



famelicus 

 Eyes removed from pronotal collar for a space equal to less than 

 dorsal width of an eye; hemelytra darkened with fuscous, 

 rarely tinged with reddish discrepans n. sp.
