TEXAN HYMENOPTERA. 253 



ample, yellowish-hyaline, nervures and stigma pale honey-yellow ; legs brown- 

 black, with pale hairs; abdomen ovate, smooth and polished, impunctured, 

 base, sides and apex with pale pubescence, apical margins of the segments 

 broadly testaceous, anal rima pale fulvous. Length .30 inch. 



Two specimen. (Belfrage.) Easily distinguished by the broad 

 testaceous apical margin of abdominal segments. 



If alictus connexus, n. sp. 



9- — Robust, head and thorax dark green, thinly clothed with short pale 

 pubescence; head broad, closely and minutely punctured, more sparsely so on 

 face and elypeus, apex of latter purplish-black and fringed with long yel- 

 lowish hairs; mandibles sometimes rufo-piceous; flagellum pale brown to- 

 wards apex; thorax very finely not closely punctured, the mesothorax with 

 the central longitudinal line generally deeply impressed anteriorly; scutellum 

 sparsely punctured, faintly impressed centrally ; base of metathorax with more 

 or less irregular radiating elevated lines generally not reaching posterior mar- 

 gin of the enclosure; pubescence on postscutellum, sides of metathorax and 

 pleura long; tegulae pale honey-yellow ; wings clear hyaline, iridescent, nerv- 

 ures and stigma very pale; legs brown, black at base, clothed with pale pubes- 

 cence ; abdomen ovate, convex, black, smoothed and polished, imperceptably 

 punctured, sides of first and second and the remaining segments clothed with 

 a short pale pubescence, becoming more dense at apex, apical margin of the 

 segments narrowly testaceous. Length .23 — .27 inch. 



Seventeen specimens. (Belfrage.) The thorax is very finely and 

 sparsely punctured, differing in that respect from the other species. 



Halictus disparilis, n. sp. 



9- — Head and thorax brassy-green, thinly clothed with a pale pubes- 

 cence; head not broad, densely punctured; elypeus sparsely punctured, apex 

 purplish-black and fringed with long pale ochraceous pubescence ; mandibles 

 more or less tinged with ferruginous ; flagellum more or less pale beneath 

 towards apex; pubescence of thorax above erect and slightly tinged with 

 ochraceous; mesothorax sparsely punctured, with a central and lateral im- 

 pressed longitudinal lines; scutellum finely and densely punctured on the 

 disk; base of metathorax more or less distinctly rugulose, with irregular radi- 

 ating elevated lines, sometimes quite obsolete; tegulae testaceous ; wings hya- 

 line, iridescent, nervures pale fuscous or pale testaceous; legs brown-black, 

 with pale pubescence, tarsi more or less pale; abdomen short ovate, convex, 

 smooth and shining, impunctured, black, with an aeneous tinge or reflection, 

 base, sides and apex clothed with a short whitish pubescence, thinly scattered 

 over disk of the segments except first and second which are nude and polished, 

 apical margin of the segments subtestaceous. Length .20— .25 inch- 

 Eight specimens. (Belfrage.) This is allied to connexus, but dif- 

 fers by the brassy-green color of head and thorax, by the more dense 

 pubescence, which is tinged with ochraceous or yellow on vertex and 

 thorax above, and by the narrower head.
