148 AMERICAN HYMEXOPTERA. 



City, New Mex., July 7, 1896, numerous at flowers of a composite 

 resembling a large Crepis or Hieracium. The sulphur-yellow flowers 

 are visited by the bees early in the morning ; as the day grows hot 

 they close. This bee is not a true Panurgus. The stigma is large, 

 and the inner angle of the second recurrent nervure with the cubital 

 is greater than a right angle. It may form the type of a new genus ; 

 it is not a Macropis. [Occurs also in Texas. — AV. J. F.] 



(8.) Panurgus pectidis n. sp. 9 . — Length about or nearly 10 mm. Head 

 and thorax black, abdomen and most of legs rufous. Head of ordinary size, face 

 broad and tlat. vertex low, cheeks not prominent, pubescence of head and thorax 

 pale ochreous, dense on cheeks and occiput, thin on face ; ocelli in a curve, hardly 

 a triangle, the lateral ones looking outward ; vertex shining, sparsely but dis- 

 tinctly punctured, front above antennae very closely punctured, pale parts of face 

 with sparse punctures, very large on clypeus ; mandibles stout, simple, medially 

 rufous; labrum black, process rounded; clypeus, except anterior edge and the 

 usual pair of bla(-k spots, and large lateral face marks primrose yellow. The 

 lateral face marks are almost exactly semicircular, but emit above a yellow line 

 ascending the orbital margin ; no supraclypeal or dogear marks ; flagellum orange 

 rufous beneath from the f(jurth joint, and towards tip more or less above; distal 

 end of funicle pallid ; mesothorax, scutellura and postscutellum densely covered 

 with short tawny pubescence, similar but longer pubescence on pleura and sides 

 of metathorax ; base of metathorax medially smooth and shining; tegulse pale 

 testaceous. Wings hyaline at base, strongly smoky beyond the cells, and more 

 or less in the outer cells; nervures and stigma brown; costal nervure black; 

 outer nervures blackish, inner becoming pale rufescent, as also the stigma, which 

 is small ; marginal cell long, terminating in an obtuse point on costa ; iirst recur- 

 rent nervure broken by one. the second by two, hyaline dots ; inner angle of the 

 second recurrent nervure with the cubital practically a right angle, only very 

 slightly less, or sometimes rather noticeably less. Legs rufous, with tolerably 

 abundant pale ochreous pubescence ; coxae blackish, femora more or less strongly 

 suffused witli black; claws with the inner tooth a minute inconspicuous denticle. 

 Abdomen orange rufous above and below shining, practically naked above except 

 the apex, which is strongly fringed with pale ochreous hairs ; dorsal surface with 

 small sparse punctures; second segment with a round black spot on each side. 

 The hind trochanters bear a curled tuft of hair, as in Andrena.

(9.) Panurgus rli(»«loceratus n. sp. 9 .—Length KS 9.5 mm. Black, 

 face wholly black ; flagellum, except first joint, orange rufous beneath, mandibles 

 rufous iu middle, small joints of tarsi rufous; pubescence dull white, grayish 

 white on dorsum of thorax, face and occiput, not at all mixed with black ; pubes- 

 cence of head and thorax rather thin, not concealing surface. Head rather 

 broad, face about square, vertex shining, clypeus sparsely punctured, cheeks 

 rounded, mandibles notched on inner side near tip ; mesothorax with short pu- 

 bescence, and larger hairs intermixed, its surface minutely punctured, with very 

 sparse, larger, obscure punctures; scutellum shining, with extremely minute
