lei, rounded at apex, not close to forceps at base. Female. — Genital 

 segment small and short, dorsal valve slightly longer than ventral and 

 less acute; pubescence sparse. 



Described from numerous males and females from Key West, 

 Florida, and Cayamas, Cuba (Schwarz), on Piscidia erythrina; these 

 are apparently paratypes; they are labeled Euplialerus jicus (MS) 

 Riley in the United States National Museum collection — apparently 

 an earlier manuscript name for the species. One female, also, from 

 Belize, British Honduras (J. D. Johnson). 



There is a certain amount of variation in the relative length of the 

 genal cones and in the color of the body. The specimens from Cuba 

 have relatively longer genal cones and are more conspicuously spotted. 

 There is an indistinct white broken stripe on the dorsum from the 

 vertex to the metascutum which scarcely is apparent in the Florida 

 forms, but is quite distinct in the Cuba specimens. The Belize 

 specimen resembles most closely the Florida forms. 



This species has nest-making habits.' 



EUPHALERUS RUGIPENNIS, new species. 



Figs. 134, 406. 



Length of body 2 mm; length of forewing 2.1 ; width of head 0.81. 

 General color yellowish orange to reddish brown, with numerous 

 irregular white spots scattered over surface of body and legs; abdomen 

 lighter ventrad; legs yellowish. Body medium in size to small. 

 Body surface coarsely punctate. 



Head large, as broad as thorax, deflexed strongly, subvertical; 

 vertex slightly impressed discally, not entirely flat, front margin 

 rounded. Genal cones large, one-half to two-thirds as long as vertex, 

 broadly rounded, not contiguous at base, divergent, not depressed 

 below plane of vertex, pubescence white, conspicuous. Eyes large, 

 recessive over propleurites. Antennae slender, less than twice as 

 long as width of head, black distad. Clypeus small. 



Thorax strongly arched, broad; pronotum moderately long; pro- 

 pleurites narrow; mesonotum long. Legs short, stout. Forewings 

 somewhat thickened, semihyaline, very conspicuously and coarsely 

 rugose, about twice as long as broad, broadly rounded at apex; 

 pterostigma rather broad at base; radial sector sinuate. 



Genitalia. — Male. — Genitalia resembling somewhat those of vermir- 

 culosus; forceps slender, somewhat three-faced, with a black, acutely 

 pointed tip; anal valve slender, long. Female. — Genital segment 

 short, thick, acute at apex. 



Described from twelve males and females from Oracle, Arizona 

 (Hubbard and Schwarz), on (?) Acacia gregii, July; twelve speci- 

 mens from Placer County, California (Koebele) , on Ceanothus cuneatus,
