NO. ii04l. THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 571 



The one Hawaiian species, the type, does not agree in all details 

 with the American species which I include in the genus, but there is 

 such a marked relationship between the two that it does not seem 

 necessary to erect a new genus for our species.

 Delphax pictifrons StAl '64: 50.- Van Duzee '.97:261. 

 Hygyo-ps picitfrons StAl '70:747. 



Length of body 4.8 mm.; width of vertex 0.25; width of frons 0.36; 

 antenje, I, 0.19, II, 0.45. General color light fulvous; frons with a 

 broad white band, sun'ounded by red, very conspicuous; a similar 

 spot on each side of pronotum just above base of coxae. 



Head with eyes fully as broad as pro thorax; vertex elongate, nar- 

 row, subrectangular, produced two-sevenths of its length beyond eyes, 

 with lateral carmae strong behhid eyes; median carina almost wanting; 

 frons tricarinate, moderately long, narrow above, conspicuously 

 broadened midway, somewhat bell-shaped, almost twice as broad at 

 apex as at base; sides parallel on lower half; c^ypeus large, convex, 

 weakly cai-inate. Eyes large, not deeply emarginate below. 

 Antennae at least as long as width of head between antennal sockets, 

 1 almost half as long as II. 



Thorax rather slender; pronotum slightly more than one-thu'd as 

 long as scuteUum, broadly emarginate behind; scuteUum rather 

 weakly carinate. Hind tibiae with two short lateral spines; calcar 

 half as long as elongate basal tarsus, coai'sely 8-dentate, acute at tip. 

 Elytra very elongate, narrow, subhyaline, veins somewhat setigerous 

 but not conspicuously so. 



Male genital segment large; viewed laterally, constricted 

 midway and long above and below; with a tubular epiphysis at base 

 of genital styles produced upward mto a short acute style; sides of 

 pygofers produced above into long, posterior projections more or less 

 encircling anal tube; anal tube and style long; genital styles not long, 

 stout, simple, acute, and incurved at apex. 



Redescribed from one female from Belize, B. Honduras (Johnson), 

 and a pair from Managua, Nicaragua (Baker). This was placed by 

 Van Duzee ^ as a species of unknown position.

 Head about as broad as pronotum, sometimes considerably broader 

 or somewhat narrower, rather strongly carinate; vertex broad, sel- 

 dom longer than broad, straight on front margin, slightly produced 

 before eyes; frons longer than broad, sides straight or rounded, tri- 

 carinate; eyes deeply emarginate below; antennae compressed, rather
