VARIATION. 



137 



8. — During the whole of the summer months, May-August, the 

 larvffi of 21yelois jnmnds inhabit the living bark of ash, frequently 

 pollard trees, never affecting any dead or decayed portions of a tree, nor 

 penetrating into the wood. It does not eat far into the bark, however 

 thick, and a few long black grains of frass block the entrance. This 

 frass is characteristic, and should be looked for when searching a tree 

 on any projecting bosses as well as on the spreading foot, for stray 

 grains of frass detected below afford a good clue to the situation of the 

 mine above (Buckler). 



9.— The larvffi of Crambm salineUm should be searched for in May 

 and June, under stones resting on Poa grass. Turning over the stones 

 exposes the tubular gallery attached to the lower whitish sheaths of 

 the grass towards the roots, or to the stone itself (Buckler). 



10.— From the beginning to the middle of June the larvae of 

 Plutella annulatella are to be found on Cochlearia cnu/lica. 



11. — The larvae of Gelechia albipalpella make conspicuous blotches 

 in the young shoots of (Tenista anglica in the early part of June. 



12. — In early June the pale green larvae of Hypolejna seqnella may 

 be beaten from maple. They are exceedingly active. 



13. — The larva of Penthina corticana feeds on birch and sallow, in 

 May and the early part of June. 



14. — The larvae of Anania (jcnhtae should be collected in May and 

 early June, when they are feeding on the shoots of (J-enista tinctoria. 

 The larvae of A. spartieUa feed on shoots and flowers of furze at about 

 the same time. 



15. — ^The larvae of Gelechia gerronella may be found in the early 

 part of June feeding on furze. 



N.B. — Hundreds of similar " Practical Hints " referring to a very 

 large proportion of the British lepidoptera, have been printed in the 

 preceding volumes. 



IT" ARI ATION. 



Aberration of Lophopteryx camelina. — I bred, on July 30th last, 

 a curious dwarfed example of Lophopterif.v camelina, without lobes on 

 the inner margin of the forewings. — F. G. Whittle, 3, Marine Avenue, 

 Southend. 



Aberration of Noctuids. — In looking through my collection, I 

 have noticed the following forms all taken near here : (1) Lencania 

 favicolor (or very near), spotless. (2) L. pallena var. arciiata, Xylo- 

 pJiasia vionof/ljjp/ia var. aethiops, and CTrainmesia tri<irammica var. 

 ohscura. — -Ibid. 



Variation in width of marginal band of Cyaniris argiolus. — 

 Some of my female Cyaniris aryiolns, which I have taken here, are 

 rather striking on account of the blue having a tinge of chalkiness in 

 the tint, whilst the black on the costa and the hind-marginal black band 

 of the forewings are of considerable width. This is in marked contrast 

 to two which I have bred this year from pupte kindly given me by my 

 friend Dr. Crallan, in which the band in the forewings narroAvs rapidly 

 after about the middle of the wing, in one insect to a point, and in 

 both specimens disappearing before reaching the inner margin. My 

 first bred specimen — a male — emerged on April 6th. The first cap- 

 tured — likewise a male — was on April 20th.— Joseph Anderson,
