The flies included in this genus are some of them more highly- 

 developed than others, having larger alulets and wider bodies ; Ron- 

 dani, therefore, placed them partly in his genus AntJiomgia, and partly 

 in Chortophila ; the greater number of them, however, have their 

 principal characters in common, possessing yellow bodies and legs, and 

 form a natural group : to these I have joined a few others which closely 

 resemble some of those in the genera Chortophila and Fhor-bia, but 

 differ in having the legs always partially yellow. R. Desvoidy formed 

 this genus to include those flies which feed in the larva state upon the 

 parenchyma of leaves ; but though most of the species included in it 

 do thus blotch or mine the leaves of various plants, the habit is not 

 peculiar to them, for some of the species in the genus Phorhia, as I 

 have already mentioned, do the same. 



P. BETJE, Curtis. 



The male of this species was well described by Curtis in tlie Journal of the 

 Royal Agricultural Society of England in 1847 ;* he overlooked, however, one im- 

 portant point, describing the palpi as being black, whereas thcj' are always yellow 

 with black ends or tips. The antennae are wholly black ; the femora and tarsi are 

 all black in the males, the tibiae only being yellow or piceous in dark varieties ; in 

 the females the femora of the four posterior legs are usually pale or yellow, while 

 those of the front pair are black or grey on their upper surfaces. 



This fly, which was formerly considered rare, and was but little known, has 

 come into rather prominent notice of late year.s, owing to the injury which it causes 

 in the larva state to the agriculturist, by feeding upon the leaves of the mangold 

 wurzel. Ifc also mines the leaves of other species of beet and Chenopodium, and Mr. 

 Inchbald sent me specimens bred from spinach leaves. 



P. CONFOEMIS, Fall. 

 This species bears considerable resemblance to the last. The female only has 

 been described, the male being unknown until I received a specimen in May, 1882, 

 from Mr. Inchbald, together with a female, both of which he had bred from the
