BRUES: PARASITIC HYMENOPTERA. 81 



gradually shorter, seventh and eighth more rapidly so. Legs, as far as 

 preserved, pale brown. Wings hyaline, stigma and veins light brown, the 

 former rather broadly ovate. Radial cell short and broad, the first section 

 of the radius fully two-thirds as long as the second; discocubital vein com- 

 posed of two straight segments, which meet sharply at almost a right angle; 

 submedian cell considerably longer than the median; discoidal nervure broken 

 much below the middle; areolet rather small, quite indistinctly closed; very 

 obliquely rhomboidal, receiving the recurrent nervure near the tip. 



Type.— No. 2268, M. C. Z., Florissant, Col. (No. 6876, S. H. 

 Scudder Coll.). 



One specimen, not very well preserved, but extremely characteristic 

 on account of the angular course of the discocubital vein. This 

 peculiarity and its general appearance make me place it here. 



Parabates memorialis, sp. nov. (Fig. 62.) 



Probably a female. Length 17 mm. Dark colored, the abdomen conspicu- 

 ously banded. Wings distinctly infuscated. Head apparently strongly 

 transverse, the antennae stout, but very much tapered apically ; joints near the 

 base of the flagellum approximately as long as thick, those toward the apex 

 becoming very little shorter in proportion to their width. Thorax rather 

 shining, its surface punctulate although faintly so. Metathorax apparently 

 with a few carinae, but not completely areolated. Abdomen large and stout, 

 much compressed, club-shaped apically and subpetiolate at the base; first to 

 fifth segments pale colored, 

 with dark apical cross bands; 

 apex of abdomen dark. 

 Ovipositor not preserved 

 although the specimen is 

 probably a female. Legs, 

 especially the posterior pair, 

 long and stout ; dark colored, 

 the tarsi pale. Wings ample, Fig. 62.— Parabates memorialis, sp. nov. Type, 

 quite distinctly infuscated ; 



stigma and veins fuscous, the former lanceolate in form. Marginal cell long 

 and narrow ; second section of the radius arcuate inwardly and then recurved 

 at its tip, twice the length of the first; submedian cell very slightly longer 

 than the median; cubitodiscoidal vein very indistinctly broken near the 

 middle, with a slight trace of a stump of a vein at this point; areolet small, 

 four-sided, the upper two sides the longest, petiolate above, the petiole as long 

 as the height of the areolet. 



One specimen, collected by Professor Cockerell, no station indicated
