at the salterns at Greifswald) is a genuine Ephydra, and Bouche's accurate 

 description of the feeler-awn sufficiently shows that it is no Ceenia. 



[Still it is probable that Heydeu is right in his supposition, and also that 

 the fly is Epliydra riparia, Fall., with which the description agrees ; what 

 Heyden says of the feeler-awn (" doubly pectinated") suits this genus better 

 than Csenia. His mistake in this case has been in referring it expressly 

 to the latter genus. The discrepancies in Bouche's figures of the larva and 

 pupa which he has noticed (ibid.) need scarcely raise a difficulty, as no one 

 who has compared the figures which illustrate that interesting work with 

 the life, will be disposed to look for more than some general resemblance.] 



Stager (Kroyer Nat. Tidsskr. N. R. 1, 36) has unravelled the differences 

 between ScatopJiaga lutaria, inquinata, spurca, Meig. He takes the first to 

 be the species so common in Sweden, and the same as Musca suilla, F. Sc. 

 spurca, Mg., agrees very nearly with Sc. lutaria, var. c. Zett. Ins. Lapp., 

 but is distinguished by light rufous feelers, the blackish margin to the seg- 

 ments of the light ferruginous abdomen in both sexes, and by the male having 

 all the thighs and the inside of the hind shanks clothed with woolly hairs, 

 these being in Sc. lutaria $ only pubescent, while this has a row of black 

 bristles and spines on the hind shanks, not found in the former. Sc. iuqui- 

 nata, which Meigen distinguishes from Sc. spurca only by the uniform 

 colour of the abdominal segments and the limpid wings, the author has not 

 seen exactly agreeing with this description, but has found individuals 

 with a dark edge to the first two segments, and with the wings nearly 

 colourless. 



Further (ibid. 38) he shows that the Sciomyza glabricula of Fallen and of 

 Meigen are two different species, the synonyms of winch he has settled thus : 



1 . Sciom. glabricula, Fall. Zett. (Sc. nigrimana, Mg., Opomyza ventralis, Mg.) 



2. Sc. aiiffustipennis, Stag., = Seiomyza glabricula, Mg. 



Again (p. 22) he gives a critical investigation of the Danish species of 

 Sepsis, including Cheligaster and Nemopoda, Macq. The species are arranged 

 according to this scheme. 1. Wings with a spot at the tip ; palps abortive ; 

 The fore legs in the have the lower edge of the thigh dilated, toothed, and 

 spined, the inside of the shank nicked. The abdomen of the male is without 

 bristles. 1. S. punctum, Mg. 2. S. violacea, Mg. 3. S. cynipsea, Mg. 4. 

 S.flavimana, Mg. (?) 5. S. aiffripes,Mg. (?) 6. S. atripes, Macq. (?) 2. Wings 

 unspotted. A. Feet of the male without any peculiar conformation : A. 

 Palps filiform or cylindrical, very small ; fore legs of the as in the 

 first section, a. Abdomen of the with a pencil of hairs at each side of 

 the last segment. 7. S. pittris, Mg. 8. AS', ciliata, new species [is S. 

 superba, Hal., Ent. Mag. i. 170], not rare in the low grounds in May. 9. 

 S. leachii, Mg. b. Abdomen of the <$ without the pencils. 10. S.faUenii,
