 Figs. 204, 208, 346, 393, 537. 



Paratrioza medicaginis Crawford '10a: 229. 

 Epitrioza medicaginis Crawford '11a: 452. 



Length of body 1.7 mm.; length of forewing 2.6; width of head 

 0.68. General color yellowish-green throughout. Body small, 

 slender. 



Head scarcely deflexed, small, not quite as broad as thorax, some- 

 what punctate. Posterior margin of vertex arcuate ; discal area with 

 a distinct foveal depression on each side of median line; anterior 

 margin somewhat emarginate at median line above front ocellus. 

 Gense swollen into two rather large globose lobes extending vertically 

 downward, shghtly visible from side, shghtly pubescent. Clypeus 

 large, prominent below genal lobes from in front. 



Thorax small, not strongly arched, quite coarsely punctate; pro- 

 no turn short; prsescutum ascending, rather small. Wings small, 

 hyaline, sometimes faintly coriaceous, less than three times as long 

 as broad, subacute at apex; marginal cells subequal. 



Genitalia. — Male. — Genital segment moderately large, rounded; 

 forceps deeply divided, bilobate or bicuspid ate; the posterior process 

 longer than anterior, more acute and glabrous; remainder of forceps 

 surface sparsely pubescent; anal valve rather large, broad at base, 

 more slender distally and terminating in a uniformly tapering 

 epiphysis, sparsely pubescent. Female. — Genital segment moderately 

 large, both valves of ahnost equal length, rather acute at apex, 

 sparsely pubescent. 



Described from several males and females from Colorado (Cock- 

 erell), on alfalfa; El Centro, California (J. C. Bridwell), on the same 

 plant, Medicago saliva. One female specimen from Jalapa, Mexico 

 (Crawford), seems to represent a species close to medicaginis, or 

 possibly identical, but until the male is known it had better remain 

 undescribed.
