Pangonia basa Loew. PANGONIA. 



Three female specimens from Connecticut. The palpi in this species are very 

 slender, and the legs of my sjiecimens seem to be lighter colored than they are de- 

 scribed. 



Pangonia tbanquilla Osten Sacken. 



A male specimen from New York agrees well with the description; the palpi are 

 noticeably shorter than in the males of any other species known to me. 



Pangonia fera, n. sp. 



Male: Length 12 mm. Black: eyes bare; proboscis longer than the tibije; basal 

 segments of abdomen yellowish red on the sides and hind margin; wings brownish 

 subhyaline, first posterior cell open; face brownish gray, with black pile; first two 

 joints of antennae black, with black hairs; palpi slender, black, with loose black 

 hair; ocelli present. Proboscis black; labellse small; dorsum of thorax brownish 

 black, with some grayish dust, and blackish pile; pleurae with some yellowish pile 

 above; abdomen black, with black pile, the three basal segments broadly on the sides, 

 and wholly on the venter, yellowish red; second, third and fourth segments with the 

 posterior margin yellow, fringed with golden pile; wings brownish subhyaline, more 

 distinctly clouded in front toward the stigma; costal and subcostal cells luteous yel- 

 low; legs wholly black, with black pile. 



One specimen, Mt. Hood. Or. Is nearest allied to P. tranquilla O. S., but the more 

 slender palpi and the black pilosity will readily distinguish it; the proboscis is also 

 distinctly longer. 



Pangonia incisukalis Say (P. ineisa, Wiedemann). 



One specimen, from New Mexico. This species will be readily recognized by the 

 elongate proboscis, small labelh*, fasciate abdomen, and closed first posterior cell. 



Pangonia chkysocoma Osten Sacken. 



A single male specimen, from New York, is evidently of this species, though the 

 sides of the abdomen are largely yellow. The author does not mention the slender 

 yellow jialpi. clothed with long, loose, black pile. The front tarsi, especially the first 

 joints, are more slender than usual. 



Pangonia dives, n.sp. 



Female: Length 13-15 mm. Head yellowish gray, the front more brownish. 

 Antennas reddish yellow, the annulate portion of the third joint largely black. Palpi 

 yellowish red, at the base with light-colored pile, otherwise with short black, more 

 or less intermixed with white hair. Proboscis about as long as the head, not ex- 

 tending much beyond the palpi, the labellae large. Ocelli present. Dorsum of 

 thorax covered with nearly uniform brownish or yellowish gray dust, nearly conceal- 

 ing the black ground-color; pubescence short, appressed, light yellowish. Pleurje 

 rather thickly gray pollinose and pilose. Scutellum like the thoracic dorsum, pile 

 light yellow. Abdomen brownish yellow, the anterior part of the segments brownish 

 or blackish, with more or less short black hair, the posterior part and margin with 

 light yellow hair. Legs reddish yellow, the tibii« somewhat, the tarsi more, brownish. 

 Wings nearly hyaline, the costal and subcostal cells yellowish; all the posterior cells 

 open, second submarginal cell appendiculate. 



Male: Eyes distinctly pubescent. Face and the slender palpi with long, abun- 

 dant, light yellowish hair, near the tip of the latter black. Thorax with rather abun- 

 dant light yellow pile. 



One male and four females, California. The eyes in life ajipear to be uniformly 

 green, or purplish green. The basal abdominal segments of the male are only faintly 

 brownish anteriorly, with a black spot, clad with black hair, near the middle. An-
