292 THE KNTOMOLOGIST. 



PoLYGONACE^. — I have bred in tolerable abundance the 

 miners of the sorrel and dock. From the sorrel, Pegomyia 

 nigritarsis, Zett., and Clwrtophila tnmsversalis, Zett. The 

 former species, says Dr. Meade, has been confounded with 

 P. fidgens, Meigen ; but Kondani says they are distinct, the true 

 P. fulgens having a yellow scutellum. It is somewhat doubtful 

 whether the continental P. fulgens has been seen in Britain. 

 From the dock {Paimex ohtusifolitis), Pegomyia nigritarsis of Zetter- 

 stedt, and P. Jncolor, Wiedmann ; very possibly, as Dr. Meade 

 remarks, feeding within the same leaf. Eobineau Desvoidy and 

 Schiner both suspected the distinctness of the miners of the 

 sorrel-dock. From the sorrel I bred largely ; I had fifty pupae, 

 but all proved to belong to one species. I had ninety- six 

 pupae of the dock, and from these two species presented 

 themselves. 



Aquifoliaceje. — I had abundantly Phytomyza aquifolii, 

 Walker, from blotched holly leaves. This insect — so common 

 with us, as to blotch in some seasons nearly every leaf — is not 

 mentioned by Schiner, Meigen, or Zetterstedt. I had a score at 

 one time in my breeding box. It differs, says Dr. Meade, from 

 P. ohscurella, Fall., in the lower j)art of the face (untergesicht), 

 being pale yellow. In P. ohscurella it is dusky ; moreover the 

 venation of the wings is different. 



Composite. — From the blotches of the burdock leaves I 

 hatched, early in May, both male and female flies of Chortophila 

 conformis, Fallen. Dr. Meade informs me that the male was 

 previously unknown ; and remarks further that it closely 

 resembles the C. rimans of Kondani, according to the description 

 which he gives of the female of that species, of which he did not 

 know the male. Another Composite, the groundsel, yielded me, 

 in fair abundance, the beautiful Sjrilographa Zoe, Meig., which 

 Bremi bred also from groundsel. It is one of the Tvypetiihe,, whose 

 lively, fanning, movements I so much admire. The larva of this 

 fly feeds within the leaves of the groundsel, usually near the 

 midrib. The pupa is pale yellow. I reared plenty, both of the 

 male and female.
