3. Phora fasciata. 



Fallen, Diptera suecica, Phytomyz., 7, 9, 1823. 

 Coquillett, Canadian Entomologist, xxvii., 103, 1893. 



Fourteen specimens. Sea level to 1500 feet. They are 

 but little different from Phora interrupta, but average 

 larger, less dark on abdomen, wings clearer, and first 

 light vein less curved. Both species have the hind 

 femora tipped with brown. 



4. Phora venataj n. sp. 



(^. Head and abdomen black, thorax brownish-black, legs 

 including tarsi yellow, femora a little darker. Palpi brown, 

 antennas blackish. Legs destitute of setae, second heavy vein not 

 forked. Anterior frontal bristles proclinate. Bristles of the front 

 small, except the verticals. Halteres brown. Under surface of 

 fore femora with a row of delicate curved hairs. Pleurae yellowish 

 below. Hypopygium yellow, rather large, with two black pro- 

 jecting claspers below and a brownish lamellar portion, bristly 

 below, projecting backward ; also a slender yellow styliform organ 

 {penis ?) in the centre below. Length 1'3 mm. 



The most noticeable peculiarity of the species is the 

 venation. The heavy veins reach beyond the middle. 

 The so-called light veins are much heavier than in any 

 other known North American species, comparatively 

 straight, and have the appearance of making a complete 

 union with the heavy veins, instead of stopping a little 

 short and then running parallel with them. 



One male. 1000 feet. 



5. Phora furtivaj n. sp. 



^ , Third vein forked, anterior frontal bristles procli- 

 nate, tibiae destitute of large bristles on the outer side ; head, 

 thorax and abdomen black, legs brownish, the tarsi and anterior 

 tibiae yellow. Front black, the bristles rather below medium 

 size, the fine hairs somewhat conspicuous, antennae blackish, more 

 or less yellowish at base, palpi yellow. Thorax sub-shining, 

 pleurae shining black, halteres black. Femora in fully coloured 

 specimens dark brown, in less mature ones yellowish-brown, the 

 tibiae lighter. Hind tarsi almost twice the length of the tibiae.
