the tegulae, two small spots on the propodeum medianly, a line on the 

 anterior and intermediate coxae, a spot on the posterior coxae, all the 

 trochanters, the apices of the anterior femora beneath, the four anterior 

 tibiae beneath, the four anterior tarsi except apices, a spot at the base 

 of the hind tibiae and a curved mark near the middle, the dorsal sur- 

 face, the dorsal basal part of the second and third joints of the hind 

 tarsi, and the base of the fourth hind tarsus white or yellowish 

 white; wings subhyaline, venation dark brown, stigma slightly paler. 



Male. Length 7 mm. Except for the usual sexual characters the 

 male agrees in structure with the female. The anterior half of the 

 clypeus is white and the posterior portion of the pronotum shows only 

 a faint indication of the white band. In some of the male paratypes 

 the white band of the pronotum is as distinct as in the female. 



St. Louis, Missouri. Described from three females and 

 seven males collected in April, 1915, by Phil Rau and given 

 his number 1518. 



Type. Cat. No. 20907, U. S. N. M. 



Macrophya simillima new species. 



This species is related to alba MacGillivray, but the short 

 antennae and long postocellar line easily separate it from Mac- 

 Gillivray's species. In habitus it resembles more closely 

 xanthonota Rohwer, but the black hind coxae of that species 

 readily separate the two. 



Female. 'Length 7.5 mm. Anterior margin of the labrum truncate; 

 anterior margin of the clypeus broadly, deeply, arcuately emarginate ; 

 the lobes narrow and rounded apically; middle and frontal foveae 

 represented by glabrous spots ; antennal furrows obsolete ; front 

 closely punctured; postocellar line subequal in length with the ocelloc- 

 cipital line and one-fifth shorter than the ocellocular line ; postocellar 

 area with its anterior width but little greater than its length, much 

 wider posteriorly, the surface with a few large, well defined punctures; 

 the sides of the vertex shining, almost impunctate ; antennae shorter 

 than the head and thorax, the third joint subequal with the fourth and 

 fifth; scutum and prescutum opaque, and with a number of irregular 

 poorly defined punctures ; scutellum shining, the sides with large, well 

 defined punctures, the appendage opaque and with two or three large 

 punctures; mesepisternum reticulate on a finely granular surface; 

 mesepimeron slightly produced posteriorly, shining, impunctate except 

 the dorsal posterior angle where it is finely granular; second cubital 

 longer than the third on the radius, subequal on the cubitus. 



Black ; base of the labrum. clypeus except the anterior margin, line 

 on the mesepisternum, posterior margins of the pronotum broadly,
