beautifully latticed witt brown on a white or cream-coloured ground, 

 I have as practically a black insect, only sparsely spotted with white 

 dots. This form occurs occasionally in the district of Basingstoke. 



Larentia multisteigaeia. — A melanic form of this occurs 

 sparingly in Aberdeenshire. 



EupiTHECiA castigata. — A black form of this species occurs 

 commonly at Paisley, and was a puzzle for several years, and called 

 the "Paisley pug." 



EupiTHECiA ALBiPUNCTA, var. ANGELICATA. — This black form is 

 not rare near York. 



EUPITHECIA EECTANGULATA, Var. NIGEOSERICEATA. — This black 



variety is quite the ordinary condition in the London district. We 

 rarely see the green form now.

DESCEIPTION OF THE LAEVA OF BOARMIA CONSORTARIA. 

 BY O. T. POREITT, F.L.S. 



Another Geometer which came commonly to sugar, but not so 

 abundantly as did TepTirosia extersaria, during the expedition of Mr. 

 W. H. Tugwell and myself to Abbott's Wood, Sussex, in June, 1892 

 (see Ent. Mo. Mag., xxxi, p. 65), was Boarmia consortaria. Eggs 

 deposited by some of the specimens taken were bright green, and 

 small for so large a moth. They hatched June 24th, and fed well on 

 oak, birch, and sallow, some of them being almost full grown by 

 August 3rd, when I described them as follows : — 



Length, about an inch and three-quarters, and slender in proportion ; head, 

 slightly narrower than [the second segment, notched, but not deeply so, on the 

 crown, the lobes rounded at the sides, but flattened in front, giving the face a flat 

 appearance. Body cylindrical, of fairly uniform width, but swollen a little towards 

 both extremities ; on the 6th segment are two prominent humps ; two other, but 

 much smaller, humps on the 12th segment ; and still two more small ones, pointing 

 horizontally, at the extreme tip of the 13th segment; skin smooth, but with a 

 slightly wrinkled appearance. 



The colour varies extremely in different specimens, but the variations are mostly 

 among the brown forms. 



Var. I has the ground-colour a pale glaucous-green, and through it the alimen- 

 tary canal can be distinctly seen, and forms a darker green dorsal line ; head yellow, 

 but almost covered with pale brown marbling ; the mandibles and a few small dots 

 at the bottom of the side of each lobe, very dark brown ; the humps on the 6th seg- 

 ment chocolate-brown, the smaller ones on the 12th segment paler brown ; spiracles
