Female: 5-7.5 mm. Antennae inserted slightly ventrad of center 

 of frons, apex of scape slightly exceeding level of posterior ocelli; 

 malar space one-half height of compound eye; frontogenal suture 

 extending ventrad from compound eye for one-half its length, then 

 deflected sharply toward mandible; left mandible with one large 

 blunt tooth and one minute acute ventral one, right mandible with 

 three blunt teeth, dorsal one largest. 



Prepectus narrow, bladelike, extending to tegula; mesotibial spur 

 minute ; outer surface of metaf emur densely covered with long pubes- 

 cence on ventral side, femoral teeth partly concealed by pubescence, 

 outer ventral margin with 16 to 20 small teeth, basal one slightly 

 larger than others; inner tooth large; apex of metatibia elongate, 

 sharp; apex of posterior tarsus with three or four long spines; claw 

 short and with several minute teeth on basal enlargement. 



Propodeum provided with coarse reticulations, two laterobasal 

 areas sometimes almost glabrous, spiracular openings vertical; pet- 

 iole twice as long as wide, surface faintly reticulated, dorsal surface 

 reticulated near base, distinct lateral carinae present ; gaster usually 

 shorter than metaf emur; cerci oval, located midway between pos- 

 terior and anterior margins of epipygium; ovipositor sheath flat- 

 tened, ventral margin acute, apex acute and provided with a dense 

 tuft of short setae; hypopygium strongly exserted, apex isolated 

 from eighth tergite (fig. 13, g). 



Male : 5-7 mm. Antennal scape (fig. 8, e) ; foretarsal claw with 

 several long, comblike teeth on basal enlargement (fig. 11, d) ; meta-

Type locality. — Texas. 



Type8.~Ro\oty^Q, female, 1790.1, Academy of Natural Sciences of 

 Philadelphia; paratypes, 1790.2, Academy of Natural Sciences of 

 Philadelphia, 1651, U. S. National Museum, 2 females. The male was 

 described as Smicra rufofemorata Cresson from Texas; types A N S P 

 No. 1779 and U.S.N.M. No. 1657. 



The species Smicra harbara Cresson was originally stated to be 

 described from a male, but the types are females. As red female 

 specimens agreeing with these types are uniformly found associated 

 with black male specimens agreeing with the type of ru,fofemorata 

 Cresson, they are undoubtedly the sexes of the same species. 



Eost.—Odontomyia sp. (Diptera, Stratiomyiidae).
