the sides shining, dark greenish black. Wings and squamae slightly 

 blackish, the halteres darker. Length: about 8 mm.; wing about 6 mm. 



North Carolina, four males (Morrison). 



Type: Cat. No. 20283 U. S. N. M. 



This species is closely related to C. nigripes. The larger size, 

 the greater swelling of the frons in the male, which also has no- 

 ticeably longer pile, the longer pile on the thorax and scutellum 

 and the absence of the stripes on the mesonotum distinguish it 

 from nigripes. The antennae are also larger. 



Chrysogaster texana, new species. 



Male: Bright steely blue. Ocellar triangle prominent, with black 

 pile. Frons well puffed out, highly polished, steel blue, with rather 

 short black pile. Antennae yellowish, the third joint darkened above, 

 ovate, nearly as broad as long, arista blackish. A whitish pollinose band 

 below the antennae extends to the eyes. Face with arcuate rugulose spots 

 directed toward the antennae and with rather poorly defined tubercle. 

 Thorax with short dark pile; mesonotum without stripes. Dorsum of 

 abdomen subopaque, the sides bright steel blue. Legs entirely dark. 

 Wings hyaline; squamae whitish; halteres dark. Length: 6.5 mm.; wing 

 6 mm. 



Female: Shining, metallic blue. Frons transversely rugose, with a 

 longitudinal ridge down the middle, above the antennae smooth and pro- 

 duced forward. Antennae reddish, arista blackish. Below the antennae 

 a rather broad band extends across to the eyes; margin of the eyes notice- 

 ably wider below than at vertex. Thorax shining metallic blue, with very 

 short pile, the mesonotum without vittae. Wings hyaline; squamae 

 tinged very slightly; halteres dark. Length: 7 mm.; wing 5.5 mm. 



Willis, Texas, one male and one female. 



Type: Cat. No. 20284 U. S. N. M. 



This species is separated from C. nigripes by the absence of 

 the vittae on the mesonotum and the pale wings and squamae; 

 the male differs in the greater inflation of the frons, the female 

 by the eyes more widely separated below. 



Genus CALIPROBOLA Rondani. 



Brachypalpus pulcher and sorosis were described by Williston 

 in his Synopsis of the Syrphidae in the genus Brachypalpus, 

 although, in his table of species he separated them off under a 

 subgenus, Caliprobola, a genus which Rondani 1 established in 

 1844 for Milesia speciosa. Verrall 2 in his British Syrphidae re-
