line; the dorsal.and subdorsal areas are grey-green, the tubercles 

 showing up distinctly, and being lighter in colour than the 

 surrounding area; the intestinal canal was distinctly visible as a 

 dark green line ; the anal plate, which is grey-green, has several 

 minute black dots distributed over its surface ; the prole gs are 

 black and glabrous. The spiracular and ventral areas are paler 

 than the dorsal and subdorsal ; the spiracles are very incon- 

 spicuous. The tubercular spines are in this stage long and 

 conspicuous. 



On May 26th this larva had attained its full growth and had 

 reached a length of 15 mm. ; it ceased feeding on May 30th and 

 spun together a portion of a plum-leai within which it changed 

 to a pupa ; the change was effected on June 4th. 



The larva conceals itself during the day by spinning together 

 the edges of a leaf (it does not roll it in any way) and hiding 

 therein, coming out to feed at night. When disturbed it is 

 intense!}^ active, wriggling violently, and progressing back- 

 wards. 



It bears a very strong resemblance to many of the other 

 species of the group Peronea, except when it is in the last instar. 

 It is in the earlier iustars superficially not at all unlike the 

 nearly-allied P. hastiana, and I think it should be recognised at 

 once, the black shining head and the grey-green segments 

 behind the prothorax should determine it from any other 

 larva feeding at the same time that I am acquainted wath. In 

 the last stage, however, it is not so distinctive, but I do not 

 know another Tortrix larva that has a similar prothorax.

There has recently appeared a " Note on a Piare Hymenop- 

 teron {Dicondylus pedestris, Curtis)," by J. Pay Hardy, in tbe 

 ' Lancashire and Cheshire Naturalist,' x, 1917, p. 77, with a 

 photo of the insect. The photo is somewhat indistinct, showing 

 neither the thoracic structure nor that of the front legs in detail. 

 It was captured in July, 1916, running on the roadside near 

 HoUingworth, in Cheshire, amongst a number of black ants 

 (Lasius niger, Linn.) at the roots of grass. The sole description 

 vouchsafed is : " Four millimetres in length, wingless, greatly 

 resembles an ant in general appearance, and is extremely agile 

 in its movements." Nor am I satisfied that " the accompanying 

 photograph will enable this insect to be readily recognised," for 

 Mr. Hardy appears to know nothing of the literature thereto 

 relating later than 1874. Parasitic Hymenoptera have been so
