evanescent on the latter : the outer half of the posterior femora 

 and tibiae are dark brown or black ; on the dorstim of the 

 thorax the two clearly defined yellow lines and lateral spots 

 are wanting, while the humeri in the 9 is black. Besides the 

 specimens collected by Mr. Daecke, I have a specimen ( 9 ) 

 from Dr. W. A. Nason, Algonquin, 111., June 9, and one ( $ ) 

 collected at Natrona, Pa., July 12. The two species which 

 have been united by L/oew (Zeits. f. Ges. Naturw. xxxvi, 114) 

 seem to be readily separated by the above characters. 



Xylomyia aterrima n. sp. 



d"> ? Black, somewhat shining ; a spot on each side above the base 

 of antennae and the frontal and facial orbits, whitish pubescent ; antennae 

 black. Humeri, a lateral line extending to the base of the wing, post-alar 

 callosities, middle of the scu tell urn, and a spot on each side of the metan- 

 otum (in the male) yellow. Halteres yellow with a brown spot at the 

 base of the knob. In the male there is a slight trace of a posterior mar- 

 gin of dark brown on the segments of the abdomen. Legs variable, in 

 the male the first and middle femora and tibite are yellow tnd in the 

 female dark brown ; hind femora of the fem?le entirely black, basal half 

 yellow in the male ; outer half of the posterior tibiae black ; tarsi brown, 

 basal half of the posterior metatarsi yellow ; coxae black, the posterior 

 half yellow ; in the male a greenish yellow tint seems to predominate. 

 Wings brownish hyaline. Length, 12 mm. 



The two specimens on which this description is based have 

 been in my collection for a number of years. The $ from ' ' N. 

 111." was given me by the late Andrew Bolter, and the 9 from 

 Franconia, N. H., was collected by Mrs. Annie T. Slosson. 

 I feel confident that a number of specimens would eliminate 

 all discrepancies. 



Symphroromyia cinerea n, sp. 



d', ?. Entire body dull gray or ash-color, with short whitish and 

 longer blackish pile, and with the lighter colored pile predominating in 

 the male. Antennae reddish or brown, the first joint moderately enlarged, 

 grayish with long white and black hairs in the male, and short black hairs 

 in the female, the small second joint noticeably darker than the others, 

 third joint comparatively small in the male, no wider than the first joint, 

 and in the female but slightly wider, aristae black, mouth parts yellowish. 

 Thorax with three obscure brownish stripes, the wide dorsal stripe divided 

 anteriorly by a fine hair line, the sub-dorsal stripes divided at the suture 

 forming two oblong spots, a small obsolete spot, also present above the 

 base of the wing. Legs yellowish, all except the metatarsi dark brown,
