BKUES: PARASITIC HYMENOPTERA. 75 



Hiatensor funditus, sp. nov. (Fig. 56.) 



Female. Length 8 mm. Head and thorax black above, the mouthparts 

 and the lower part of the thorax, except the hind coxae, yellowish. Abdomen 

 black, the apical four segments more or less reddish brown on their basal por- 

 tions. Hind legs black; anterior and middle pairs yellowish, their tarsi darker 

 apically ; wings hyaline. Antennae long slender, and of even thickness through- 

 out; most of the joints about three times as long as wide. Mesonotum shin- 

 ing; metathorax coarsely and regularly rugose reticulate. First abdominal 

 segment as long as the metathorax, very gradually swollen toward the tip; 

 second as long as the first; body of ab- 

 domen gradually enlarged behind, com- 

 pressed; third segment much enlarged 

 behind, three- fourths as long as the 

 second and nearly as high behind as it 

 is long; fourth and fifth widening; 

 sixth and seventh narrowing slightly, Fig. 56. — Hiatensor funditus, sp. nov. 

 the latter rounded behind; ovipositor Type, 



short, one-half as long as the abdominal 



petiole and flattened blade-like. Posterior legs very long, but shorter than in 

 the preceding species, the apex of the femora, reaching just about to the tip 

 of the abdomen, the femora clavate, the thickening beginning just beyond the 

 middle, the thickest part four times as thick as the slender basal portion. 

 Wings with narrow stigma, the marginal cell narrow; first section of the radius 

 hardly longer than the basal vein; first recurrent nervure received just beyond 

 the basal one-fourth of the discocubital cell ; second recurrent nervure received 

 just beyond the first transverse cubitus.

 7167 (reverse), S. H. Sendder Coll.). 



This resembles II. semirutus in the extremely elongate and clavate 

 form of the hind femora, but differs by the narrower marginal cell 

 and shorter second abdominal segment; otherwise they are very simi- 

 lar and I think undoubtedly congeneric. 



Limnerium Holmgren. 



Key to the Florissant species of Limnerium. 



1. Areolet either petiolate or touching the radius in a point with its 



upper angle just attaining the radius 2. 



Areolet distinctly sessile above, i. e. with a distinct radial side. 



L. vetustum, sp. nov.
