coarsely so below; propodeum with numerous fine indistinct 
punctures, tessellate, the basal triangle tessellate or granular; 
tegulse bronze-piceous, minutely punctured; wings subhyaline, 
faintly clouded apically, nervures brownish-testaceous, basal ner- 
vure beyond transverse median, second recurrent nervure en- 
tering second submarginal cell nearer apex than the first does to 
base; legs black, pubescence fuscous, tinged with red beneath 
tarsi and on middle metatarsi without, black on the outer faces 
of the tibiae, middle and hind metatarsi fully as broad as their 
tibiae; spurs yellowish-brown; claws reddish-testaceous basally, 
darker apically, with indistinct basal teeth. 
Abdomen cordate-ovoid, shining, finely punctate, closely so 
on basal segments, sparsely so on the apical ones except the sixth, 
pubescence black, entirely fuscous on segment X, and segments 
2-5 with inconspicuous apical fuscous fasciae; segment 6 very 
slightly, if at all, concave at sides in the dorsal view, straight in 
profile, shining, finely and rather closely punctured, with sub- 
appressed fuscous pubescence and numerous erect black hairs; 
scopa fuscous, shorter and deeper black on segment 6. Length 
10.5 mm. 
Type: Female (Type No. 15718, Mus. Comp. Zook); Uma- 
tilla, Oregon, June 24, 1882 (Samuel Henshaw, collector). 
This would appear to be near M. vandykei Ckll., but in that 
species the pubescence is entirely black, and the clypeus is des- 
cribed as being “densely rugoso-punctate, with a polished shining 
spot at middle of upper edge, and a median band in which the 
surface is shining between the punctures, lower margin thick- 
ened, slightly emarginate in middle.” The clypeus in this species 
does not answer to that description at all, and the pubescence is 
fuscous rather than black, with definite though inconspicuous 
fuscous fascise. It may be possible that this is a melanistic form 
of some light haired species.

$ . Head with eyes slightly converging below; supra- 
clypeal plate shining, sparsely punctate medially; clypeus close- 
ly and rather coarsely punctured in general, but with the punc- 
tures well separated in the center, apical margin entire, the edge
