Panurginus pauper var. flavntinctus, Ckll. — Prof. C. H. T. 

 Townsend took two males at Dripping Spring, Organ Mountains, 

 N. M., Aug. 10th. I formerly thought they might belong to 

 P. asteris, Eob. The female of flavotinctus, taken at Santa Fe in 

 August, differs from the male in the broader flattened abdomen, 

 and the wholly dark face. It will be distinguished from the 

 female of albitarsis by its small size (about 5 millim.), and the 

 flagellum being ferruginous beneath after the fourth segment. 



Panurginus albitarsis subsp. fortior, subsp. nov. 



$ . About 6| inillim. long. Differs from Santa Fe albitarsis in 

 being more robust, with a broader abdomen, having indeed the build 

 of a female rather than of a male. Wings quite clear ; stigma and 

 nervures rather pale brown ; face-markings a deep chrome-yellow, 

 whereas in the Santa Fe insect they are pale lemon-yellow. Flagellum 

 entirely black. 



Hab. Mescalero, N. M., July 22nd, 1898. (C. M. Barber.) 

 This is probably a valid species. 



Panurginus barberi, n. sp. 



$. Length about 7 millim., black, with a thin short greyish 

 pubescence, making the insect appear dusty ; abdomen narrow with 

 subparallel sides ; head, mesotborax, and scutellum with large and 

 rather dense punctures, not dense enough, however, to obscure the 

 shining surface ; metathorax with its middle part shining and im- 

 punctate, its base with a narrow transverse channel crossed by little 

 ridges at frequent intervals ; abdomen shining, with only a few small 

 scattered punctures at the sides of the first segment, the other segments 

 with the anterior half rather thickly but minutely punctured ; antennas 

 entirely black ; face scarcely hairy, clypeus (except two black dots, 

 and the pale brown anterior margin) and lateral face-marks bright 

 lemon -yellow ; lateral marks rapidly narrowing above the level of the 

 clypeus, ending in a sharp point (at an angle of about 45°) on the 

 orbital margin just below the level of the antennas ; labrum mostly 

 yellow ; mandibles simply yellow at base, otherwise reddish brown, 

 with a conspicuous tuft of hair on the lower margin about the middle ; 

 tubercles yellow with a hyaline spot ; tegulse testaceous : wings 

 smoky, especially on the apical margin, nervures and stigma piceous ; 

 marginal cell with a long appendicular nervure ; second submarginal 

 cell receiving the recurrent nervures near the end of its first and 

 beginning of its last fifths ; legs black, bases of last four tibiae, all the 

 knees, basal two-thirds of anterior tibiae in front, and basal joints of 

 all the tarsi, pale yellow. 



Hab. Mescalero, New Mexico, July 12th, 1898. (Chas. M. 

 Barber.) In my table of Calliopsis and Panurginus this runs to 

 P. bidentis, Ckll., but it will be easily known from that by its larger 

 size, and the absence of the strong yellowish tint of the wings. 



Calliopsis obscurellus, Cresson, 1879. — Three males and three 

 females from Pasco, Wash., May 25th, 1896. {T. Kincaid.)
