damp leaves), when the drawer is pulled out the moths would be 

 caught by the cross bar above the drawer at m. 



(2.) The piece of glass from k to l. This joins the piece from 

 K to M, and, from my own observation, prevents many moths, 

 which otherwise would crawl up the glass and escape, from 

 doing so. 



(3.) Placing the upper point of the lower glass, or k, behind 

 instead of under the lower point of the upper one, or j. This 

 does not in any way check the moths from going in, but tends 

 much to prevent their getting out, as if they fly about there is 

 really no opening, as they tiy against one or other of the 

 glasses. 



Of course I do not for a moment pretend that the trap is 

 perfect, or that many improvements may not be introduced, and 

 I fancy a great deal more use might advantageously be made of 

 zinc in its construction. Again, I do not suggest that the 

 measurements are the best ; all I can say is, that they are those 

 I have used, and they have answered.

EHOPALOCERA. 

 PIEEIDJE. 



PiERis BRA.ssic^, L. — Abundant, and generally distributed. 

 Irish specimens are not divergent to any extent from those of 

 Great Britain. The black apex of fore wing is often dusted with 

 white scales. Markree Castle, Sligo, and elsewhere. Mr. Russ 

 has a female from that neighbourhood, in which the black apex 

 extends in streaks interiorly towards the upper spot. Mr. Barrett 

 records (' Lep. of Brit. Is.'j " a very small form from the North 

 of Ireland."' Usually the Irish insect is both large and strongly 

 marked. 



PiEEis RAP.aE, L. — Generally distributed, but the least common 

 of the three species of Pieris found in Ireland. Variable in the 

 size and strength of the black markings in both sexes, and in 

 both broods. The apical shading is sometimes almost obsolete, 

 and the spots reduced. Of the varieties described by Mr. Dale, 

 in his ' History of British Butterflies,' I have taken var. b, with 

 pale cream-coloured wings ; and one forced in winter has this 

 peculiarity, and inconspicuous black spots and apex (var. c). 



Var. metra, Stph. — A very fine example of this variety, devoid 

 of all markings on the upper side of fore wings, was taken by 

 Mr. FethersDon H. [cf'. Newman, "Brit. Butterflies,' p. iblj.
