6868 Insects. 



signification of the terra ? In my opinion most assuredly not. To carry out my view, 

 the whole batch of fifty-six pupa? should have produced perfect insects, but only three 

 appeared as above [stated. When I say the whole fifty-six should have produced 

 insects, I mean, of course, that none should have survived to " put in an appearance " 

 next spring. It is but honest in me to state that these observations, made by me 

 in doors, are apparently utterly at variance with those made by Mr. C, R. Bree out of 

 doors (Zool. 587J). Mr. Bree states that in the beginning of August a second brood 

 appears, more numerous than the first, i. e., in May. Now mi/ August brood con- 

 sisted of three out of fifty-six, while my brood in the forthcoming May will com- 

 prise the remaining fifty-three, plus those produced from the eggs laid by the August 

 three, about as many more ! Should these remarts of mine meet his eye or those 

 of Mr. Crewe, I shall feel much obliged if they would communicate, in the pages 

 of the ' Zoologist,' some additional and more specific information on the subject. I 

 ask this because I know that Stowmarket is the head-quarters of the insect, avid that 

 both gentlemen had ample opportunities of observing its habits. To proceed. Judging 

 exclusively from my own experience, I believe that S. conspiouaria, N. dictaea, N. 

 ziczac, P. palpina, and probably many others, are farlially double-brooded ; that is, a 

 few specimens emerge the same year (for what particular purpose I do not know, 

 except perhaps to obviate the danger of extirpation, — a circumstance not unlikely to 

 occur in the present day), while the vast majority live through the winter in the pupa 

 state. Nay, I go further, and must add that according to my experience even this 

 very limited appearance is exceptional. I readily allow that the remarks of Mr. 

 Gascoyne, of Newark (Zool. and Intell. passim), militate strongly against my theory. 

 He speaks of whole broods appearing in the autumn from eggs laid in the spring. 

 From what I have already stated it will be seen how completely this is opposed 

 to my experience. I do not attempt to explain the discrepancy ; but if these few 

 remarks are received in the spirit in which they are offered, viz., that of investi- 

 gation and inquiry, they may probably provoke a friendly (and I deprecate any 

 other) discussion. If so, from among your numerous correspondents some further 

 and valuable information may reasonably be expected. — Joseph Greene; Cubley

Description of the Larva of Eupithecia tenuiata. — Short and stumpy. Ground- 

 colour dirty yellowish-green. Sides and centre of back slightly tinged with rose- 

 colour. Down the centre of the back a row of very indistinct dusky spots, becoming 

 confluent in a black line at the anal segment, and bordered by an interrupted black 

 line. On each side a row of slanting tubercular flesh-coloured stripes. Head and 

 fore feet black. Feeds on the catkins of sallow, in spring. Full-fed the end of 

 March and beginning of April. In appearance it much resembles the larva of 

 Eupithecia Haworlhiata. I am indebted to the kindness of Mr. Doubleday for the 

 larva from which the foregoing description was takt n. — H. Harpur Crewe ; Medsled,

Description of the Larva of Eupithecia nanata. — Long and very slender, tapering 

 towards the head. Ground-colour white or greenish-white, with a chain of pear- 

 shaped red dorsal spots, bordered on either side by an interrupted line of the same 

 colour, and becoming confluent on the capital and anal segments. Sides spotted with 

 red. Belly with a central red line running the whole length. Body clothed with a 

 few very short hairs. A very pretty variety of this larva has the ground-colour bright 

 green, with a series of tooth- or pear-sh.iped white dorsal spots, intersected by a central
