NEW AMERICAN PARASITIC CYNIPID^ (ALLOTRIIN^). 



BY CARL F. BAKER, FORT COLLINS, COLO. 



All of the species described below were taken in Colorado. For 

 most of the specimens I am indebted to the industry of my wife, who has 

 done a large amount of work with the sweep net in Northern Colorado. 

 No American species have yet been described as belonging to any of the 

 genera mentioned, though some of the species described under Al/otria 

 may possibly be referable to some one of them. A number of species of 

 Allotria in my collection are left until such time as the already described 

 forms are more fully elucidated. 



Phaenoglyphis, Forster. 



This genus is separated from Allotria by the parapsidal furrows and 

 scutellar fovea. 



Phae?ioglyphis aniericana, n. sp. 



Male. — Shining black, legs and antennae honey-yellow. Length, i mm. 

 Antenna? 14-jointed, approximate at base, sockets twice as far from eyes 

 as from each other, reaching beyond the middle of the abdomen ; joint 2 

 as long as i, 3 twice as long and distinctly bent inwardly, 4 and 5 some- 

 what shorter than 2 ; apical joint long, conical, and blackish at tip. Oral 

 region castaneous. Face, prothorax above, mesonotum at sides, scutellum, 

 metathorax and base of abdomen with fine white hair, longest on the 

 scutellum. Parapsidal furrows distinct, not approximate behind, gently 

 diverging anteriorly and extending the entire length of mesonotum. 

 Scutellum with a large semicircular fovea at base. Metanotum opaque 

 and with two longitudinal caringe, which are equidistant from each other 

 and the lateral margins. Tegular piceous. Wings as long as whole body; 

 median vein obsolete ; radial cell closed, two and a-half times long as 

 wide; appendix below long, slender, straight, and slightly knobbed at end; 

 radius extending somewhat beyond juncture with marginal vein. Cubital 

 and discoidal veins faintly outlined. Fort Collins ; May. 



Dyliia, Forster. 



Under this genus I describe several species in which the radial cell 

 is open for a greater or less distance on the anterior border, and in which 

 the radius is narrowly rounded at tip and does not reach the margin of 

 the wing. Some of the species resemble quite closely various species of 

 Alloxysta, but in that genus the radius spreads out irregularly at tip, and 

 there is no appreciable space between it and the margin of the wing.
