Psyche 
[March 
pleural carina and on most of metasternum; gaster fulvous with 
some faint and diffuse dusky staining; legs fulvous with tibiae and 
tarsi duller and fifth tarsomeres dusky, front coxa extensively white 
above and in front with a large dark brown dorsal blotch enclosed 
by the white, front trochanter white tinged dorso-anteriorly and 
with slight dusky staining above; mid coxa with a large white blotch 
on basal half anterio-dorsally, mid trochanter brownish stained 
above; and with a little dusky on apex of hind trochantellus; wings 
hyaline with stigma pale brown. 
Length of fore wing: 6.3 mm. First flagellomere: 5.0 as long as 
deep at apex. Clvpeus: small, in profile rather strongly and a little 
asymmetrically convex, its apical margin slightly convex. Malar 
space: 0.85 as long as basal width of mandible. Temple: at its 
upper 1/3 about 0.34 as long as eye in lateral view; strongly re- 
ceding and gently convex. Mesoscutum: smooth and shining with 
abundant, moderately small, sharp punctures (coarser and denser 
in thoracicus). Mesopleuron: prepectal carina sharp to about lower 
0.2 of hind margin of pronotum and then becoming obsolete in a 
vertically elliptic, slightly raised white callus. Wing venation: areo- 
let 1.3 as wide as high at apex; nervulus interstitial. Hind trochan- 
tellus: 0.20 as long as hind trochanter in dorsal view. Propodeum: 
elongate and rather strongly sloping rearward with little disconti- 
nuity between basal and apical face, apical face 0.7 as long as basal; 
apical trans-carina absent medially, laterally forming very low, 
broad, weakly oblique subcrescentic cristae; surface strongly and 
densely punctate with some intercalated wrinkling, especially rear- 
ward and a little more finely and sparsely punctate basad of basal 
trans-carina. First gastric segment: postpetiole 0.8 1 as wide apically 
as long from spiracle to apex. Second gastric tergite: mat with very 
fine but well developed micro-reticulation and abundant small, 
shallow punctures separated mostly by a little more or a little less 
than their diameters. Ovipositor: sheathed portion 0.83 as long 
as fore wing; tip 0.7 as long from nodus to apex as deep at nodus. 
MALE: Unknown. 
TYPE: In collection of Henry K. Townes, 5950 Warren Rd., Ann 
Arbor, Michigan, 48105. 
RELATIONSHIPS: This species resembles M. sicarius Townes (1962, 
p. 448-450), especially because of its short prepectal carina which 
ends dorsally in a white callus, but may be distinguished by the 
characters summarized in the following key:
