1915] Smith— New Species of Tachinidw (Dipfera) 101 



row of facial bristles. Antenna inserted at a point above the middle of the eye, 

 black pollinose; the third joint with a faint rufous tinge at its base, about four times 

 as long as the second antennal joint. Arista thickened on its bassal two-fifths to one- 

 half, the penultimate joint two times as long as broad. Cheeks shining black, polli- 

 nose, about one-third as wide as the eye height, bearing several long bristles near 

 the center and scattering black bristly hairs. Palpi black. 



Thorax shining black, grayish pollinose, with a bronzy tinge, marked with three 

 black vittJB. Three dorso-central and three sterno-pleural macrochseta;. Scutellum 

 black, bearing three pairs of marginal macrochseta?, the apical pair cruciate. Bristles 

 of scutellar disk, erect. 



Abdomen shining black, grayish pollinose on the basal margins of the three pos- 

 terior segments. The second segment bearing a median discal and marginal pair 

 of machrocha-ta;, the third a discal pair and marginal row, and the fourth bristly on 

 its apical two-thirds. Bristly hairs of the abdomen appressed. 



"Wings hyahne, faintly tinged with brownish at the base and along the costa. 

 Posterior cross-vein and the fourth longitudinal vein beyond the bend also faintly 

 bordered with brownish. Third longitudinal vein bristly to the small cross-vein. 

 Fourth longitudinal vein beyond the bend abruptly curved inwardly. Calj^pteres 

 whitish. 



Described from two male specimens taken by Mr. C. W. John- 

 son, in honor of whom this species is named. 



One male (Holotype), N. E. Harbor, Me., July 26, 1909. 



One male (Paratype), Machias, Me., July 19. Both specimens 

 in the collection of the Boston Society of Natural History. 



Neopales noctuiformis sp. nov. 



Black, grayish pollinose. Length 6-8 mm. 



Front about as wide as either eye. Eyes hairy. Frontal vitta opaque reddish 

 black. Ocellar bristles strong, proclinate. Orbital bristles absent in the male. 

 Sides of front black, grayish pollinose with a yellowish tinge. Frontal row of bristles 

 descending to or shghtly below the base of the third antennal joint; outside of these 

 a row of shorter bristles i and irregularly placed, bristly black hairs. Sides of face 

 densely gray poUinose, less than one-third as wide as the median depression. Facial 

 ridges bristly on the lowest three-fifths. Antennae black, the third joint three and 

 one-half to five times as long as the second. Arista thickened on the basal two to 

 three-fifths, the penultimate joint longer than broad. Cheeks one-fifth as wide as 

 the eye height, bearing bristly black hairs and a row of stout bristles on the anterior 

 margins. Vibrissse placed on the oral margin. Palpi yellow or brownish. 



Thorax black, grayish pollinose, marked with five rather indistinct ^^ttse. Four 

 dorso-central and three ^ sterno-pleural macrochsetfe. Legs black, knees rufous. 



1 In the holotype the row of bristles on the front, outside of the frontal row, are very weak, 

 more closely simulating bristly hairs; whereas, in the four paratype specimens thisrow of bristles 

 is quite distinct and prominent. This slight variation is very probably due to the artificial con" 

 ditions of rearing to which the holotype was subjected. 



2 The specimens from North Andover, Mass., and Sugar Island, Me., each have three sterno- 

 pleural bristles on one side and four on the other.
