maturity. I subjoin a description of this larva, as possibly 

 some of your correspondents may recognise it: — Length Ig- 

 inch : body tapering anteriorly. Head large, triangular, of a 

 deep shining green colour, with lateral yellow stripes ; a red- 

 dish spot at the apex ; a paler green and granulated on the 

 back of the head behind the stripes : mandibles black. Body 

 apple-green, thickly covered with small greenish yellow 

 granulations; the anterior segments semitransparent ; on 

 each side seven faint greenish yellow oblique stripes edged 

 anteriorly with large granulations, the central stripes having 

 a reddish tinge, the last stripe wider than the rest and ter- 

 minating at the base of the caudal horn, the latter at an 

 angle of 20*^, recurved backwards, purplish red and thickly 

 granulated ; the anal plate with a central elongated black 

 patch, with a larger granulation on each side : stigmata 

 small, round, and dull red. Under surface slightly paler 

 than the upper, with a darker central line. Feet pale green, 

 spotted with red ; prologs greenish, semitransparent. — E. B. 

 Reed^ in the ' Canadian Entonioloyist.^ 



[I'his description corresponds very nearly to that of the 

 larva of Smerinthus excoecatus, by Mr. Lintner (Pro. E. S. 

 Phil. iii. p. QQ^). We have never ourselves met with any 

 Lepidopterous larva that emitted sounds ; the imago of Sesia 

 Thysbe is described by Dr. Gibb (Can. Nat. and Geo]. 1859, 

 p. 122) us giving forth a loud and most striking note, "some- 

 thing like the squeaking of a mouse or a bat," which he 

 attributes to the action of the respiratory organs. Tlie well- 

 known European death's-head moth (Acherontia Atropos) 

 emits a somewhat singular noise, even before leaving the 

 pupa-case, as well as afterwards ; Kirby & Spence state 

 further (letter xxiv.) that " its caterpillar, if disturbed at all, 

 draws back rapidly, making at the same time a rather loud 

 noise, which has been compared to the crack of an electric

Tortrix pomonana — The present has so far been a very 

 trying season as regards vermin in the gardens ; calerpillars 

 and blight of all kinds have been very abundant, as might 

 have been looked for from the mildness of tlie winter. But of 

 all the pests that infest the garden, 1 find none so difficult to 

 deal with as that dreadful apple-moth, the Tortrix pomonana. 

 My apple-trees, particularly sonje of my espaliers, have for
