180 Cocker ell New American Bees. 



on the thorax does not extend so far forward, and the hind margin of the 

 first abdominal segment is black (broadly yellowish-white in gph&ralceie}. 

 It looks like a diminutive M. pallidicincta, but has not the broad head of 

 that species. It belongs to the group of M. inter medulla, humilior and 

 sphierulcex. Compared with M. humilior Ckll., and M. intermediella Ckll., 

 the abdomen is much narrower, with much broader hair-bands ; the an 

 tennae also are much darker. 



Habitat. Pecos, New Mexico. W. P. Cockerell. 



Melissodes pecosella ve*besinarum subsp. nov. 



Female. Rather more robust; hair on inner side of basal joint of hind 

 tarsi more decidedly fuscous ; flagellum, after the first two Joints, bright fer 

 ruginous beneath ; basal band of second abdominal segment broad and very 

 white ; hair of thorax in front paler; eyes pile sea-green. Could very 

 easily be taken for an undersized pallidicincta, but the much narrower face 

 at once distinguishes it. 



Habitat. Las Cruces, New Mexico, at flowers of Verbesina encelioides. 

 September 22. T. D. A. Cockerell. 



Melissodes nigrosignata pallidisignata subsp. nov. 



Female. Segments 2 to 4 of abdomen almost wholly covered with pale 

 ochraceous hair; hair on outer sideof middle tarsi all yellowish-white ; spurs 

 pallid. Easily known from M. grinddi.se by the entirely light hair of the 

 tegulse. Maxillary palpi as usual in the genus. This has a very distinct 

 appearance, but seems to be only a variety. The characteristic fulvous and 

 black hair of the hind legs is as in the type. There is a general resem 

 blance to M. suffusa. 



Habitat. Oak Creek Canyon, Arizona, 6,000 feet. August. F. H. Snow

Melissodes hortivagans sp. nov. 



J/u/e. Length about 13.5 mm.; black, rather stout; head and thorax with 

 abundant grayish-white pubescence very faintly tinged with ochraceous 

 above, scutellum with some short black hair; eyes pale yellowish-gray; 

 head broad, facial quadrangle not far from square; clypeus (except a small 

 spot on each side), labrum and basal half of mandibles lemon-yellow; 

 apical part of mandibles with a fulvous stripe ; antennae rather long, third 

 joint much longer than second ; fourth longest of all, but notas long as the 

 next two together ; last joint normal; flagellum wholly bright ferruginous 

 beneath ; mesothorax and scutellum shining and well-punctured ; tegulee 

 red, fuscous in front ; wings very strongly stained with yellow, stigma fer 

 ruginous, nervures dark ferruginous; second submarginal cell much shorter 

 than first or third, oblique but with almost equal sides; first recurrent 

 nervure entering it not much beyond the middle ; hair of legs wholly pale, 

 that on inner side of tarsi orange-ferruginous ; tarsi ferruginous, as also are 

 the tibiae at apex and largely on inner side ; abdomen with conspicuous 

 but rather narrow entire median (or submedian) white hair-bands on seg-
