reddish-yellow, remainder of tibiae fuscous, tarsi ferruginous. Clypeal 
shield with a central carina; honey-yellow with a central black dot. 
Antennae rufous, 41-jointed, the scape and pedicel yellow below. Wings 
deeply infuscated but hyaline at the tip, i. e., beyond the second recur- 
rent nervure. Stigma fulvous, veins piceous. The facial shield is some- 
what less than twice as hig-h as wide, rounded below, the sides nearly 
straight, converging; clypeus truncate. The antennae are short and 
stout, scarcelj^ more than half the lengi^h of the body, the fiag"ellar 
joints, toward the apex, at least three times as wide as long-. 
Male. Length 8mm. This sex is much lighter in color, with the 
wing's more strongfly infuscated. The legs are entirely yellow except 
for reddish blotcheiS at the base of the hind ooxae and at the middle of 
the hind femora. The pro-, meso-, and metapleurae each have a large 
yellow spot that almost entirely covers them and there is a stripe just 
below the mesosternal suture. The mesonotum has a large j^ellow spot 
connected with a large triangular humeral yellow spot. The tegiilae 
are also yellow. The facial shield is lemon-yellow, and slightly nar- 
rower than in the female. The antennae are 39-jointed, the fiagellum 
ferruginous. The bands on the abdomen are wider, occupying nearly 
the entire second segment, two-thirds of the third, and more than one- 
half of the following ones. 
Described from two specimens, male and female, from Fedor, 
Lee Co., Texas. They were sent to me by Rev. G. Birkman with 
a number of interesting Texan Hymenoptera. 
The sexes are so dissimilar, that unless associated might be 
taken for distinct species. The present form resembles M. ruiipes 
Cresson from Colorado, but the hind legs of the female are more 
or less black and the clypeal shield yellow while there is no rufous 
on the legs or abdomen
