THE CANADIAN ENTOxMOLOGlST. 261 



Gall - wasp. — $ . Length 2 mm. Polished black, very sparsely 

 pubescent. Antenn.-e r4-jointed, about two-thirds the length of the^ 

 body, the first joint or scape obcoiiical, slightly curved, swollen at tip, the 

 second joint about i ]A times as Ions: as thick, both much stouter than the 

 flagellum. Mesopleura smooth, shining, with a deep vertical femoral 

 fovea. Legs, except knees or the extreme apices of the femora, which 

 are dull honey-yellow, entirely black. 



Hab. — Manhattan, Riley County, Kansas. 



Described from a single specimen received nearly ten years ago from 

 Mr. C. L. Marlatt. The wasp, according to Mr. Marlatt, issues from the 

 gall early in January. 



ZopHEROTERAS, gen. nov. 



This genus also comes very close to P/ii/onix, Fitch, but is readily 

 separated from it by the shape of the scutellum, by antennal characters, 

 by bareness of abdomen, and by the claws of the hind tarsi being simple, 

 not toothed. 



The frons and mesonotum are alutaceous or feebly shagreened, the 

 latter having distinct traces of the parapsidal furrows, or at least these are 

 more or less distinct posteriorly. The scutellum is rounded or semi- 

 circular, rounded off posteriorly and separated from the mesonotum by a 

 delicate grooved line and carina. The antennae are long, 14-jointed, the 

 third joint as long or nearly as long as joints 4 and 5 united ; joints 6-13 

 are a little more thpn twice as long as thick. Claws of hmd tarsi simple. 

 The abdomen is longer than the head and thorax united, bare, or at the 

 most with only some sparse pubescence at sides towards the base ; the 

 second segment dorsally occupies fully half the whole surface; segments 3-5 

 short, subequal ; segments 6 and 7 very short ; while the hypopygium is 

 armed with a hairy spine. 



To this genus belongs Acraspis vaccinii, Ashm. 



Xanthoteras, gen. nov. 



Head shagreened, the frons without a distinct ridge or carina be- 

 tween the antennae. Mesonotum polished, with deep, distinct parapsidal 

 furrows. Scutellum with more or less distinct lateral margins or with a 

 frenum, two indistinct shallow foveae at base and the same separated from 

 the base of the mesonotum by a delicate but distinct transverse grooved 

 line and a carina. Antenna? r4-jointed, the third joint a little longer than 

 the fourth, or the latter about two-thirds the length of the third ; joints
