"It flies in marshy meadows among Carices in August" (Gn. 

 Ind., 61). It may be best distinguished from its congeners by its 

 mottled ochreous ground colour and entire dark central fascia, broadest 

 in the middle, with a black spot at its hinder edge. 



It has been taken rather commonly near London, by Messrs. 

 McLachlan, Machin, and others, among Alisma plantago, upon which 

 plant it is said, by Heinemann and Zeller, to feed. Mr. Machin now 

 informs me that he has reared it this season from larvse feeding in the 

 stems of Alisma in the Hackney Marshes. It also occurs more rarely 

 in the Norfolk fens. 



Although Wilkinson's description of griseana seems to have been 

 taken from this insect, his observations upon it are most puzzling, 

 since it is not very similar to Vectisana, nor does it at all resemble his 

 subroseana (cilieUa, Iliibn.). Moreover, the species which has been 

 reared from Inula dysenterica is not this, but notulana, Tt., as proved 

 by specimens sent me by Mr. Doubleday. I suspect, however, that it 

 is to this species that M. Jourdheuille refers in his Calendar, when he 

 gives Alisma plantago as the food-plant of Mussehliana and of notulana.

Note on a species of Apion new to the British list. — There are two examples 

 ((? and ? ) of an Apion set aside in Dr. J. A. Power's collection, taken by himself 

 in 1867, at Hastings, which differ considerably from any recorded British species, 

 and arc, I think (in spite of a discrepancy in measurement), to be referred to A. 

 opeticum, Bach (Wencker, Mon. des Apionides, p. 10). That species is described as 

 differing from poHJOJicE in its size being often smaller (the smallest being 2\ mill.), 

 its invariably black colom% its rostrum being more abruptly contracted a little after 

 the middle, and less dilated at the base in both sexes, and its antennal club being 

 pointed-OToid, — the club being more elongate in pomonce. Now, Dr. Power's insects 

 agree well enough with opeticum as thus characterized (the lesser basal dilatation of 

 the rostrum being best seen laterally), except that they barely exceed two mill, in 

 length {rostro exclusd). They have, as should opeticum, entirely the facies of subu- 

 latum, but with the rostrum shorter, stouter at the base, and more abruptly contracted. 

 They are of the same size as small craccce, but less pubescent, especially in front, 

 with only the base of the first antennal joint testaceous, &c. According to Wencker, 

 A. opeticum lives on Orolus vernus. — E. C. Rte, Parkfield, Putney, S.W. : No-

Observations on a viviparous ChrysomeJa. — With reference to the note on this 

 subject by M. Bleuze, a translation of which appeared in our last number {ante 

 p. 135), M. Valery Mayet has ^hcw^l in the Pet. Nouv. Entomologiqucs for 1st No- 

 vember, 1874, that the fact is not new, it having been already recorded by M. Perroud 

 in the Annales do la Soc. Linneene de Lyon for 1855. This article is entitled " Notice 

 Bur la viviparity ou I'ovoviviparite des Oreina speciosa ct sttperha," pp. 402 — 406 ; 

 and, according to M. Mayet, Chrysomela (or OreipaJ venusta may be only a variety
