ThoHC lopidopttrists who liuve Part I of this work should certainly have 

 Part 11 before coimnencing the main part of the season's work. It is very 

 much lar<4er than Part I, contains entirely new material, the genercil cha[)ters 

 have full and detailed infor)n:i,tion on all the most successful methods 

 adopted for breeding lepidoptera, and the hints comprise some information 

 on the means of obtaining almost ail the species of British Macro-Lepi- 

 doptera. The following is a sample page of the "hints " for August, from 

 p. 1V2:— 



Mellinia fiilvurio comes freelj- to lij^ht in August (at Cambridge, Eeadiuf,', Ax'.), and 

 is sometimes taken from the lamps in and near towns in large numbers, probably only 

 where avenues of elms exist in the sul)urbs of the towns. 



Towards the end of August, at about p.m., search should be made at the base of 

 ash-trees, and on the dibrh around, for freshly-emerged imagines of Cirrhoedia 

 xorampelina. 



In the Church Strctton district, imagines of Cirrhocdia xcrani peluia are to be obtained 

 at the foot of some large ash trees, clinging to blades of grass, at the end of August and 

 early in September, the trunks rarely giving a single specimen. 



In the middle of August the imagines of Lithomia saUdafiiiiix occur freely on a piece 

 of boggy heath near Wilsden. At rest this species has a most remarkable resemblance 

 to the e.Kcrement of grouse — the male particularly so. It folds its wings round its body, 

 clasps a stone with its legs and raises its body to an angle of about 30^, its markings, 

 colour, shape, and mode of attachment make the imitation almost perfect. 



Litlioiiud tioliddfiiiiis abounds in Cannock Chase in late .\ugust. The imagines are 

 very easy to find, as they sit on the birch-tree trunks during the daytime, principally with 

 their heads thrust into some crevice in the bark, so that their bodies stand out at right 

 angles to the trunks of the trees, rendering them conspicuous. As many as 150 have 

 been taken on one day. the greatest number on a single tree being seven. 



The larvii! of CitcnlUd Uiclniil'm will e;it Scrojihnlaria uquattca as well as Verba kciiiii, 

 prciVrring the buds and blossoms. 



Everyone who has the opportunity should devote some days during the first fortnight 

 of August to searching for larva of (.'iiciilUa niiaphaiii in the Kent wooda. It is easy to 

 make a small, light beating tray of black calico, sewn to a frame of stout iron wire, and, 

 having found an opening in the woods where the golden-rod is plentiful, each plant should 

 be beaten gently with a light stick into the tray, which should he held against the pl.inl- 

 stalk, low down near the ground. I'lenty of larvie of C. axteris will be obtained, and of 

 Eupitheciids too, but the larva of C. unnpltnlii is unmistakable with its dull green colour- 

 ing and purple dorsal stripe. An avei-age of one to a hard day's work is good (P. C. IJeid). 

 The imagines of Stilbitt (Hioinalti are best taken on Cannock Chase in early 

 August, beginniuis to make their appearance about? p.m., and continuing to fly till about 

 S.HO p.m. The insect is very conspicuous on the wing, the ample lower wings' making it 

 appear almost, white when flying; it gets up suddenly out of the heather and short grass, 

 flies ten or twelve yards, and then drops down again, folding its dark upper wings closely 

 over the lower ones, and thus, in a moment, becoming almost invisible, so that, unless 

 one marks very e.xactly the spot where it falls, it is impossible to detect it. Frequently, 

 however, it will fly up again almost directly, when, of course, it may be " snapped " with 

 (he net (Thorncwill).
