ENTOMOLOGY. 113 



Camelina or Dictcea is naturally double-brooded, until one or more of the 

 pupae of those species dug up in a normal state, produce the perfect insect 

 the same year. I dig at poplars, oaks, elms, etc., all the year round, 

 but I never found a pupa of either betvjeen the first week in June and 

 the last week in July.

Ceropacha Jlavicornis. — I find there is a great discrepancy in the appearance 

 of the larva of C. Jlavicornis. Stainton, in "Manual," says it is found in Sep- 

 tember; the Rev. Mr. Greene informs us it is taken in June. Now at what 

 period does the moth appear? — with us in the very early spring. From March 

 20th. to April 9th., I took fifteen specimens; did not see one after this date. 

 The larva I have not yet taken, but have no doubt that it is full-fed at the 

 end of May and beginning of June. In Scotland, perhaps, the insect comes 

 out later, then the larva will be found late also. If you could give your 

 dates, and all those making district lists give theirs, some approximation to the 

 truth would necessarily ensue, and we should then have correct data to write 

 upon. So again, with the discrepancies of L. callunee. I have bred L. quercus 

 very largely both from egg and larvae found. I have never seen one of its 

 larva? with blue rings, both the males and females vary as to their shades of 

 colour, at least my specimens do. — C. Gr. Cox, Fordwych House, Canterbury,

Larvae of JEgeria Bembiciformis. — In cutting sallows, where 2E. Bembici- 

 formis abounds, the rods ought to be taken off near the root, the larva, if 

 present, will be on the stem about seven or eight inches up; cut a piece of 

 the wood off, say fourteen inches long, the insect will be almost certain to 

 be found in it; take it home, insert the piece either in damp moss or mould, 

 placed in a box with a gauze cover; the sallow will grow, and the perfect insect 

 appear in due time. Should you have the larvae only, then bore a hole two 

 inches up the centre of a piece of sallow large enough for the insect to bury 

 in; the piece ought to be about an inch or an inch and a quarter in diameter; 

 this will grow well in a fingerglass: by adopting this simple plan I rarely 

 fail. Last year I bred a great many, and was delighted to see them take 

 wing. I found they had laid their eggs on some young sallow at my door 

 — a grateful return. — Idem. 



Larva; of Sphinx ligustri. — The larva of S. ligustri feeds in this neighbour- 

 hood principally upon the Laurustinus. I took twenty-five off one small bush, 

 a most unusual thing, as this, as well as all large caterpillars, I believe, are 

 solitary feeders, at least my experience leads me to think so; but the larvae 

 of S. ligustri is found here frequently doing damage to the young hollies; 

 every year I take them off my large holly trees. In the nursery-grounds 

 near me they strip the young shoots bare; my servant recently brought 

 me one in, that he dug up at the foot of a large solitary oak tree, far 

 away from any other, it must therefore have fed upon the oak. (I may
