294^ Information respecting the Otiorhynchus sulcdtus, 



probable that Bjercander had described the habits of several 

 distinct insects, illustrating them only by the description of a 

 single species." That this, most probably, is the case, appears from 

 a very interesting memoir by Olivier, which seems to have been 

 unknown to all subsequent dipterologists, in which eight distinct 

 species are described which attack the Cerealia ; one of which is 

 the O'scinis pumilionis of Fabricius, or the Chlorops pumilionis 

 of Meigen and Stephens, and is stated by this author to have 

 been found in all the different kinds of rye and barley, which it 

 seems to attack in preference to the wheat, although occasionally 

 found in the latter. I have also received from D. Sharpe, Esq., 

 F.L.S., &c., a fly twice the size of those from Mr. Raddon, which he 

 reared from wheat in Huntingdonshire, that was attacked, when 

 6 in. or 8 in. out of the ground, by the larva, which devoured the 

 centre of the stem, and so killed the plants. It is not shining, 

 like the Chlorops glabra described above ; and the yellow marks 

 on the thorax are less conspicuous : the tips of the femora, as 

 well as the tibiae and tarsi, are brown : the nerves of the wings 

 are arranged as in Chlorops glabra. The pupa from which this 

 fly was produced is represented above, in ^g. 101. h i, of the 

 natural size, and magnified: it is of a shining pale yellowish buff" 

 colour. 



Art. II. Farther Information respectiyig the Coleopterous Insect 

 Otiorhynchus sulcatus, and its Ravages on the Vine. By W. Lin- 

 wooD, F.H.S., &c. ; with some Remarks from J. O. Westwood, 

 F.L.S. 



The following letter, received from W. Linwood, Esq., of 

 Enfield, gives us further information relative to the habits of the 

 Otiorhynchus sulcatus, an insect whose destructive powers seem 

 far more general than had been imagined. I am happy that the 

 information thus received from different correspondents (see, 

 also, p. 286.) will enable us to arrive at something like a know- 

 ledge of the economy of the insect in question. Persons, also, 

 who may possess information upon any other of the insects in- 

 cluded in my series, will render good service to cultivators by 

 coming forward, as Messrs. Castles, Linwood, and J. B. W., 

 have done, and communicating the result of their observations to 

 you. 



« To J. O. Westwood, Esq.. 



" Sir, I beg leave to send you a memorandum, written on 

 reading your article in the Gardener's Magazine, p. 157., for 

 April last, which may throw some further light on an insect 

 carrying on its operations chiefly in the dark. 



" It is with much pleasure I at last see the description of an 

 insect which has annoyed me, more or less, for the last thirty
