92 Phoridae. 



I shall here premise the remarks that in the following descriptions 

 the costal divisions of the wing are named 1,2 and 3; 1 is the space 

 from the humeral cross- vein to the inner border of the jimction of 

 the first vein with costa, 2 the space from here to the inner border 

 of the junction of the second vein with costa, and 3 the space from 

 this point to the end; the length of costa is measured from the longer 

 bristles present on its base. 



I. Phorinae.

{Chaetoneura Malloch, Glasgow Naturalist I, 1909, 26). 



Species of relatively large size. Frons broader than long, with 

 strong bristles forming three transverse rows with four bristles in 

 each row; at the anterior corner one pair of smaller supraantennal 

 bristles, directed backwards. Eyes hairy. Antennæ inserted near the 

 middle of the head, sometimes somewhat larger in the male than in 

 the female; arista dorsal. Clypeus distinct, a little protruding, espec- 

 ially in the female. Palpi with the bristles sometimes shorter in the 

 male than in the female. Proboscis a little more robust in the female 

 than in the male. At the side margins of the oral aperture a row of 

 oral bristles and on the cheeks a number of two to five genal bristles; 

 one long and conspicuous lower postocular bristle. Thorax with one 

 pair of dorsocentral bristles. Scutellum with four bristles. Mesopleura 

 bare. Abdomen in the male with the sixth and generally also the 

 second segment elongated. Hypopygium of medium to somewhat 

 large size; it is not quite symmetricai as the two side parts of the 

 tergite are of different size and shape and the left fissured; below, 

 generally on the right side, is a narrow, somewhat claw-shaped piece, 

 and in some species (thoracica, caliginosa) there is on the left side a 

 triangular plate between the side of the hypopygium and the sixth 

 segment; a variously shaped ventral plate is present; the anal tube 

 somewhat or very short, cylindrical or nearly. In the female the 

 sixth abdominal segment is elongated; (about the special construc- 

 tion of abdomen in the female of thoracica see under that species). 

 Abdomen is very sparingly haired with quite short hairs and such 

 hairs are present at the hind margins of the segments; at the hind 

 margin of sixth segment they are longer, and at the lateral margin
