178 Cocherell — New American Bees. 



a little broader ; fifth segment with the hair brown-black or very dark 

 chocolate in the middle, white at the sides; sixth with it very dark choco- 

 late; ventral segments 4 and 5 with much short dark red hair about their 

 middle and on hind margin ; spurs pale, normal ; tegulfe rufous ; wings short, 

 clear, nervures ferruginous ; hair on inner side of basal joint of hind tarsi 

 ferruginous; facial quadrangle about square; flagellum, except basally, fer- 

 ruginous beneath. This is one of the belfragei group, and is best defined 

 by comparison with other species. It can not be the 9 of .S'. lepida Cr., 

 because the disc of mesothorax is dull and densely punctured (in lepida 

 shining with well-separated punctures, though the anterior part is dull and 

 densely and minutely rugoso-punctate, in complete contrast), and the mar- 

 ginal cell is conspicuously shorter, and more rounded at the end. It has 

 nearly the appearance of lionesta, so far as regards the thoracic pubescence 

 and abdominal bands; but honeKia, according to Robertson, is the cJ* of bel- 

 fragei, with which it certainly agrees (differing from cressoniana) in having 

 the hind margins of the second and third abdominal segments free from 

 pubescence, the bands not being really marginal. From S. belfragei 9, 

 cressonwna differs greatly in its smaller size; in the base of the second 

 abdominal segment having a conspicuous liglit band (in belfragei the base 

 is perfectly black, the second segment having only one band); and in the 

 ferruginous under side of flagellum. From .S'. rir^ff/rt {S. belfragei virgaia 

 Ckll.) it differs by its narrower abdomen, with a conspicuous band at base 

 of second segment; the lack of light ventral hair-bands ; the rounded apex 

 of marginal cell; thecolor of theantennse, etc. From S. fuwleri CkU. it diffi^rs 

 by the bright ochraceous hair of thorax above ; the much redder antennte ; 

 the very distinctly though densely punctured disc of mesothorax (this part 

 infowleri being granular with separated weak punctures); and in havingthe 

 black parts of the abdomen distinctly punctured and bare, not covered 

 over with black tomentum. The punctation of the abdomen resembles 

 greatly that of }felis.'<ndeii spi)<sa Cresson. 



Habitat. — Texas (no other particulars known) ; from the Cresson collec- 

 tion. 



Synhalonia fuscotincta sp. nov. 



Female. — Length about 11 mm.; form and appearance of S. fonderi Ckll., 

 though narrower, and easilj' distinguished by the fact that the hind part 

 of the disc of mesothorax, and the scutellum, are covered with dark 

 fuscous hair. The maxillary palpi are 6-jointed, as is normal in the genus. 

 Abdomen with broad white hair-bands at hind margins of segments 2 to 

 4, and the fifth segment with a white patch on each side. Flagellum black, 

 with only the faintest reddish tinge beneath near apex; vertex without 

 black hair, but one or two hairs over the ocelli have a fuscous stain ; man- 

 dibles black ; pubescence generally white, but of mesothorax, where not 

 fuscous, stained with ochraceous; tegulse shining piceous; wings rather 

 short, slightly dusky, nervures black; first recurrent nervure joining second 

 submarginal cell at its end; hair of legs mostly white, that on inner side 

 of basal joint of hind tarsi ferruginous, tuft on hind knees pale smoky ;
