an elongate oblique band nearly meeting its fellow of the opposite 
side of each of the third and fourth segments, and apex, yellow. On 
the venter the hind margins of the third and fourth segments are 
yellow for their entire width, nearly the whole of the middle part of 
the second segment and a narrow band on the posterior margin of 
the first segment are also yellow. The lateral margins of the seg- 
ments of the abdomen are black between the yellow markings, and 
there is no connection between the yellow markings on the abdo- 
men. 
A female specimen taken by E. J. Oslar at Boulder, Colorado, 
August 19, 1899. 
In many respects this species agrees with Osten Sacken's de- 
cem-maculatus, but it cannot be that species as the markings are 
very different. Aside from the hairy eyes it appears to belong to 
Euparyphus. The third joint of the antennae is composed of six 
rings with the last ring the longest. The fifth posterior cell meets 
the discal and its general form agrees very closely with bellies and 
tetraspilus 
Akroxia n. gen. (Fig. 1.) 
Head conically produced. 
Front in the female noticea- 
bly wider than the eye, in 
the male about half as wide 
as in the female. Antennae 
three-jointed, first and sec- 
ond joints about equal in 
length, third much longer 
than the other two together 
and composed of six rings. 
Posterior orbits wide in both 
sexes, but widest in the fe- 
male, scutellum without 
spines, four posterior veins 
arising from the discal cell, 
abdomen short and broad, 
fig i nearly circular in outline. 
Named for Akron, Ohio, in which vicinity 1 have procured many 
rare species. 
Akronia frontosa n. sp. 
Length 4-4^ram. Dull black, sparsely clothed with very short, 
•light-colored hair; eyes widely separated in both sexes, naked; an- 
tennae entirely in front of the eyes; front produced more in the fe- 
male than in the male, posterior orbits present in both sexes, widest 
in the female; thorax nearly equally four-sided, scutellum without 
spines, wings hyaline, veins bounding costal, basal, marginal, and
