OF WASHINGTON, VOLUME XVII, 1915 133 



about as wide apically as long, much shorter than second, anterior excava- 

 tion polished, carinse obsolescent, sparsely punctate apically and more 

 strongly so laterally; tergites 2-5 similarly punctured, the elevations MM 

 3-5 nearly impunctate. 



Black with mesonotum laterally, scutellum entirely, and pnst-r.it* 'Hum 

 apically, rufous; spot belo\v the tegula, meso.sternum and pleura' below, 

 hind coxae and all femora ferruginous: mandibles pale at base; pedicel 

 beneath and scape narrowly at apex, palpi, front and middle coxa 1 , tro- 

 ehanters, except basal joint of hind pair, tegular and line on proiioium, 

 whitish; hind tibiae with a yellowish longitudinal stripe below which en- 

 tirely embraces the tip, upper side whitish with small infuscated spot near 

 base; remaining portions of legs pale stramineous with the hind tai>al 

 joints darker apically; wings hyaline, veins and stigma fuscous \\hite 

 at base. 



Male. Length 8.5 mm., antennae 5.5 mm. Differs from female as fol- 

 lows: face relatively somewhat longer; ocell-ocular line somewhat shorter 

 than postocellar line; first tergite about one-third longer than wide, pol- 

 ished medially. 



The ferruginous color is paler throughout and embraces the entire 

 mesonotum and metapleurae in addition to the areas enumerated in the 

 description of the female; legs paler, front and middle pairs largely white. 



Host: Anthonomous grandis thurberice Pierce. 



Type locality: Santa Rita Mts., Ariz. 



Type: Cat. No. 19157, U. S. N. M. 



Described from two females and a male reared from larva- 

 of the host in bolls of Thurberia thespesioides, the females from 

 material collected by Mr. E. A. Schwarz, April 12, 1913, in Stone 

 Cabin Canyon and the male from material collected by Mr. 

 Schwarz March 12, 1913 at McCleary's Ranch, both localities 

 in the Santa Rita Mts. The paratype female is almost identical 

 with the type.

 GENUS HOMASPIS Foerster. 



The only character used by Foerster to separate this genus 

 from Notopygus Holmgren is the lack of an arcolet in the front 

 wing. The genotype, H. rufinux (Crav.i. lias the arenlet, while 

 Davis's two species and the one described below lack it. Better 

 characters for separating the two genera are found in the apically 

 impressed clypeus in Homaspis and its slender legs, the hind 

 tibiae being much longer than their femora, while in Notopygus 

 the hind tibia* are very stout and hardly longer than their femora.
