Huachuca Mts., Arizona. (Schaeffer). One male in excellent 

 condition. 



This neat little species differs principally from those so far known 

 by the coloration of the abdomen and legs. 



Eccritosia amphinome Walker. 



Of this handsome species I have taken a female in the Huachuca 

 Mts., Arizona. It is reported in the Aldrich catalogue from Lower 

 California, Mexico, Guatemala and Honduras. 



Erax subcupreus new species. 



Head grayish-white pollinose, except the facial tubercle, which is almost 

 without pollen and shows the brownish-submetallic ground color ; mystax with 

 white and black hairs and bristles; occipito-orbital and ocellar hairs and bris- 

 tles black ; beard white ; palpi black, with black hairs and bristles. Thorax 

 brownish-metallic, with grayish-white and brownish-gray pollen ; median line 

 with a rather dense crest of erect, black hairs, which does not extend to the 

 scutellum, between the crest and the scutellum are moderately long, white 

 hairs, intermixed with some black bristks. Scutellum somewhat densely 

 clothed with moderately long white hairs and along the apical margin with 

 some black bristles. Pleurae feebly pollinose and with sparse darker and white 

 hairs. Abdomen black with very faint brownish-metallic tint, segments one 

 to five with long white hairs, parted at middle and directed outwards, those 

 on the first segment are only on the thickened apical margin and on the second 

 covering about apical third of the segment ; segments six and seven grayish- 

 white pollinose and covered with shorter white hairs. Hypopygium black with 

 sparse gray and blackish hairs. Venter clothed with long white hairs which 

 become shorter on the apical segments. Wings hyaline, slightly smoky towards 

 the tip ; costa distinctly thickened and dilated. Femora black with brownish 

 submetallic tint, tibiae brownish, at tip black, tarsi black ; femora and tibiae 

 clothed with moderately long, white and gray hairs. Length 18 mm. 



A single male from Prescott, Ariz., received from George Franck. 



Apparently related to E. costalis Will, but with abdominal seg- 

 ments one to five, with long, white hairs. Williston, in his synoptic 

 table of the species of Erax^ gave the name costalis but neglected to
