No.:i04l. THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 597 



Male genitalia similar to hal:en, with genital styles smaller, less 

 prominent, more slender; processes of anal tube very small, blunt, 

 not prominent. 



Redescribed from three macropteroiis females from Alabama 

 (Baker), one macropterous male from Columbus, Texas, 46 brachyp- 

 terous males and females from Colorado and Alabama (Baker), and 

 one brachypterous female from Mexico (Baker). 



The one male from Columbus, Texas, is one of the two specimens 

 upon which Van Duzee based his original description of Pissonotus 

 hasalis. P. delicatus he first described from a single brachypterous 

 female, so that it is not surprising that he did not recognize the two 

 as identical, as they surely are. 



DICRANOTROPIS FRONTALIS, new species. 

 Plate 46, fig. L. 



Length of body, 2.6 mm.; width of vertex, 0.22; width of frons, 

 0.27; antennae I, 0.18, II, 0.32. General color brown; abdomen 

 brown, with light blotches, lighter at base; elytra light brown, veins 

 light ; scuteUum brown, pronotum dirty white mth brown blotches; 

 vertex dirty white wdth a black spot in each fovea ; frons light brown 

 with several transverse white bands, as in apMdioides; clypeus black ; 

 forecoxse black, femora and tibiae light brown striated with black. 



Somewhat similar to a2)7iidioides. Head short ; vertex weakly cari- 

 nate, rather broad in female, as broad as long, but in male slightly 

 longer than broad; frontal carina forked weU down from apex o*f 

 head, indistinct on apex; antennae as long as frons, I half as long as 

 II. Lateral carinae of pronotum disappearing near hind margin. 

 Hind tibiae longer than femora (one abnormal tibia has three lateral 

 spines) ; calcar more than half as long as basal tarsus, margin finely 

 dentate. Male genitalia in general similar to hakeri, but wdth genital 

 styles sinuate, clavate-spatulate at tip ; pygofers at base of styles with 

 one pair of short, rounded processes ; anal tube produced ventrad into 

 a pair of very long, acute processes, extending almost to base of styles. 



Described from one brachypterous pair, the male from Claremont, 

 California, and the female from Oregon (Baker). 



Type-specimen. — Cat. No. 15980, U.S.N.M. (female) ; (male), in col- 

 lection of Pomona College.

 Pissonotus a phidioides Van Duzee '97:239.— Osborn 'SI7:235; '0^:100. 

 Average length of body, 2.9 mm.; width of vertex, 0.20; width of

 men irregularly black; pronotum and scuteUum pale between lateral 

 carinse, brown outside; frons and apex of vertex mottled, dark brown
