to be reason to tliiiik that Zaddach's (^ was really oue of P. lineolata, 

 and that tlie true puhescens c? is an insect more resemblino- the ? , 

 which was reared along with the latter by Giraud (Ann. Ent. Soc. 

 France, 1871), and which is stated {vide Andre " Species, &c.," Vol. i, 

 p. 304) to have the " first two " abdominal " segments bordered with 

 white or pale yellow, and all the rest tawny in the middle and whitish 

 on the sides." 



P.puhescens does not seem to be a common species anywhere, unless 

 perhaps in some parts of G-ermany. Thomson describes nothing like 

 it in " Hymenoptera Scandinavise," nor is it mentioned by Costa 

 among the Italian species. The colouring of the ? is so distinctive 

 that it is luilikely to be mistaken for anything else. Now that it is 

 known to occur in this country, it may be hoped that other captures 

 will be made, and possibly such doubts as still remain asjto'the true ^ 

 of the species be cleared vip. 



Its larva is said to be very like that of lineolata (for a full 

 description of which vide Cameron Mon., Vol. i, p. 242), but without 

 the yellow dorsal line, and of a somewhat greater size (8 lines long 

 according to Zaddach) . It should be looked for in June, feeding on 

 oak-leaves, and the imagines should appear in April of the year 

 following.

ADDITIONS AND COERECTIONS TO THE BEITISH LIST OF 

 MUSCIBM ACALYPTRATM. 



BY J. E. COLLIN, F.E.S. 



(Continued from Vol. xlvii, page 187). 



ASTIADJE. 



Astia elegantula, Zett., was first recorded as occiu-ring in Britain by Mr. P. 



Jenkinson, on page 4 of this Magazine for 1904. Dr. Wood has since taken it 



in Herefordshire. 



*Liomyza laevigata, Meig,, may be recognised by its black halteres with 

 yellow stems. I have taken it here at Newmarket and at Barton Mills (Suffolk), 

 also in Woodditton Wood (Cambs.) in May and August, while Col. Yerbury has 

 taken it at Tarrington (Hei'eford). The geniis Liomyza is now generally con- 

 sidered to be closely allied to Astia. 



Liomyza scatophagina. Fin. — This is the L. fiavipes. Fin., of the " List," 

 which Zetterstedt sank as a synonym of scatophagina. It may be readily dis- 

 tinguished by its pale halteres from Ixvigata, Meig.
