The species is described from two males and two females bred 

 from Pholus vitis Linnaeus, Washington, D. C, the flies issuing 

 October 8, 1884; also a specimen collected by R. P. Currie, Plummer 

 Island, Md., June 3, 1902. 



The reared specimens are evidently some of the material Coquillett 

 had before him when working on his Revision of Tachinidae. The 

 species is exceedingly close to aletiae (Riley) from which it is differ- 

 entiated principally by its marginal bristles on the second abdominal 

 segement and color characters; testacea differs from pholi in its 

 more slender form, coloration and density of pollen along the thorax, 

 the latter character being readily recognized when a series of speci- 

 mens are examined. 



Type.—Mdile. Cat. No. 43054, U.S.N.M., from Washington.

The type specimen can not be located in the United States National 

 Museum. Such being the case, the species is redescribed from one 

 male and two females from Centerville, Fla., which are considered 

 as typical. These specimens were reared from Alabama argillacea 

 Hiibner and are labelled, "#468 LOS, issued Nov. 23, 1878." Another 

 female varying but slightly from the above is included as typical. 

 This specimen is labelled as follows: "#2359 — bred from aletiae 

 pupae, disclosed Aug. 21, 1881, Hubbard; collection C. V. Riley — 

 104." It also bears Brauer and Bergenstamm determination label, 

 '•^Prosopaea sp." and is evidently the specimen sent by Riley to them 

 for identification.^" The specimens above compare well with Riley's 

 description excepting in the case of the one labeled Prosofoea, in 

 which case the front and face are cinereous without trace of golden 

 pollen. 



Front of male at vertex 0.26, at widest part 0.34 the head width; 

 in female at vertex 0.27, at widest part 0.34 the head width ; face and 

 front concolorous, ashy gray ground color tinged with golden; 

 frontal vitta one-third the frontal width; frontals nine in number, 

 the last two pairs reclinate. Antennae black, second joint brownish, 

 in male about one-fourth the length of third, in female about one- 

 third. Facial ridges weakly or strongly bristly for one-half to 

 three-fourths their length. Bucca narrow, about one-tenth the eye 

 height. Palpi yellow, eyes sparsely but distinctly pubescent under 

 high magnification.
