NEW SPECIES OF HYMENOPTERA. 39 



The two females from which the foregoing description was 

 made were taken in Illinois, one in 1897 at Chicago, and the 

 other on August 16, 1899, at Meredosia, in central Illinois, 

 where the fauna and flora are decidedly southern. This is a very 



distinct species. 



PARNOPES WESTCOTTII, sp. nov. 



Male. Length, 7 mm. Bright metallic green varied with coppery re- 

 flections. Rugosely punctured. Covered with silvery pubescence as fol- 

 lows : face as far as anterior ocellus densely ; metapleuras densely ; sides of 

 scutellum and of postscutellum densely ; tegulae sparsely ; suture between 

 prothorax and metathorax sparsely ; posterior portions of abdominal seg- 

 ments sparsely, but more densely at the sides ; and distal portions of the 

 legs moderately. A few scattered hairs are present on the occiput, 

 thoracic dorsum, coxae, and femora. Punctures rather irregularly placed, 

 stronger on thorax than on abdomen, confluent behind the ocelli, where 

 they are radially arranged, the rows diverging anteriorly. Antennae with 

 the scape piceous and flagellum yellowish. Clypeus emarginate, although 

 not so strongly as \nfestitus, yellowish at apex. Mandibles rufous, metal- 

 lic green at base and black at tip. Proboscis reaching back to the middle 

 of the first abdominal segment. Thorax green, with bronze tint, especially 

 when viewed from in front. Prothorax with a rather well-marked median 

 impression. Tegulae broad, yellow, disc darker, sparsely punctured. Be- 

 tween the parapsidal grooves the mesonotum is less brilliant. Scutellum 

 and postscutellum piceous, more strongly punctured than the rest of the 

 thorax. Postscutellum excised to nearly its middle, the sinus rounded at 

 the bottom and with a width of about 70 degrees. Sides of postscutellum 

 slightly rounded outwardly. Abdominal segments blue at anterior margin, 

 varying through green and cupreous to piceous on posterior depressed 

 third. This depressed portion is provided with much smaller and confluen, 

 punctures, and with the white pubescence parted on the median line. Fourth 

 segment with two wide subapical oblique grooves separated posteriorly, 

 beyond which it is fulvous : its apical margin denticulate, with seventeen 

 teeth in upper rows, below which is a series of lighter colored and more 

 pronounced teeth, the apical two of which are almost spiniform. Venter 

 shining, uniformly fulvous. Legs fulvous, excepting the metallic green 

 coxae and femora. The trochanters, knees, and upper surface of anterior 

 femora are lighter. Wings hyaline, the nervures testaceous. 



Female. Length, 6.5 mm. Differs from male as follows: Color, a 

 stronger green, with less of the cupreous reflections. Face broader. Scape 

 of antennae with greenish tinge. Clypeus not so evidently emarginate, 

 black. Mandibles black except rufous spot in middle. Proboscis reaching 

 as far as last abdominal segment. Occipital punctures not radially ar- 

 ranged. Sides of postscutellum, straight. Apical depressed bands of 

 abdominal segments much narrower. The third segment (apical) has
