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- 

 €em-7naculatu8, 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 bellus and 

 tetraspilus 



Akronia 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. 1. nearly circular in outline. 



Named for Akron, Ohio, in which vicinity 1 have procured many 

 rare species. 



Akronia frontosa n. sp. 



Length 4-4)^mm. 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
