T. vaga, Wlk. : this is probably no Tipula at all, and could I see 

 the original, I could most likely name it at once ; my belief is tbat it 

 is a Oylindrotoma. 



Dictenidia bimaculata, L. : I can give as localities, Worcester 

 (Fletcher) and Guestling (Bloorufield). 



Xiphura atrata, L. : I have a beautiful series of this species, 

 proving the synonymy of ruficornis, Stasg., from Dr. T. A. Chapman 

 (vide Ent. Mo. Mag., vi, p. 31). 



X. nigricornis, Mg. : from some Diptera given me by Mr. G. C. 



Bignell, of Plymouth, is a specimen which I foci sure must represent 



this species.

ON TWO ADDITIONAL BRITISH SPECIES OF SARCOPRAGIDJE, 

 OR FLESH FLIES. 



BY E. H. MEADE. 



In 1876, I published a short Monograph in the 12th vol. of this 

 Magazino upon the British species of the genus Sarcophaga, in which 

 I briefly described twenty species ; since then only two fresh species 

 belonging to the samo family have come under my notice, one of 

 which belongs to the restricted genus Sarcophaga, and seems to be 

 new to science ; while the other has been placed in the genus Theria 

 by K. Desvoidy, and though known upon the continent of Europe, has 

 not before been recorded, I believe, as an inhabitant of England. The 

 genus Theria contains only a single species, which, though included 

 in the family of the Sarcophagidce, because the arista is plumose at 

 its base, bears a much closer general resemblance to the flies in the 

 family of the Tachiniidce ; the body being shorter and wider, and, 

 together with the legs, furnished with stronger and more numerous 

 spines than in the true Sarcophagce. 



E. Desvoidy gave the fly upon which he founded this genus, in 

 183U, the specific name of palparis, but it had been previously de- 

 scribed, in 1826, by Meigen, as Sarcophaga muscaria; it must, therefore, 

 retain the latter specific name, as it has the claim of priority. 



Theeia mtjscabia. 



Measures 12 mm. (about 6 lines) in length ; it is of a black-grey colour, tessel- 

 lated, and marked with white in a somewhat similar manner to Sarcophaga carnaria ; 

 it has large yellow palpi, somewhat thickened at the ends ; the thorax is cinereous, 

 -marked by three wide longitudinal black stripes; the apex of the male abdomen is 

 clubbed, but the segments arc much smaller than in S. carnaria ; the tibia; are 

 armed externally with a regular row of bristles of oven lengths, but the hind ones 

 arc without beards on their innor sides in the male, as in S. carnaria.
