median puncta has perhaps not yet been caused in urticce, as also 

 not yet the development of the margin of female ichnusa. 



Altogether it appears that aberrations of V. urticce, which are 

 facially transitional to icluiusa (not merely to var. turcica), are 

 very rare indeed, much rarer than such aberrations as ab. 

 atrebatensis, ab. ichnusoides (a misleading name rather), ccerul- 

 apicata, ignea, and others.

The Selandriades comprise ten genera and fifty-three species, 

 very many of which are extremely abundant everywhere, and 

 among the first to be acquired by the collector. Harpiphorus 

 lepidus, a very distinct insect, is, however, rare in my experience. 

 I beat it from undergrowth in the Bentley Woods, near Ipswich, 

 in the middle of May, 1897, and on April 22nd, 1901, discovered 

 a larva in a cell, apparently of its own construction, in a gall of 

 Cynips kollari on oak in the same locality. This larva became 

 a green pupa on the 25th and remained green till May 11th, 

 when the colour changed to yellow and black, those of the 

 imago. It subsequently appeared to develop into its perfect 

 condition in a curiously gradual manner. On May 12th the 

 pupa could walk with a certain amount of ease, and during the 

 same evening it was yet more active ; on the 13th it had changed 

 little in appearance, but was certainly an imago with legs, 

 antennas, and, mouth-organs fully developed, though the wings 

 remained somewhat immature. I still possess the larval skin, 

 which is too shrivelled for description. Cameron (Phyt. Hym. 

 i. 265) had no personal knowledge of the ecdysis of this species ; 

 but Fitch records (Entom. 1880, p. 258) four specimens bred 

 from galls of the same species of Cynipid. 



The Suffolk coast is especially cursed with Athalia spinarum, 

 whence it has been recorded "in such numbers in July as to 

 render the turnip crops leafless in August" (Ent. Ann. 1860, 

 p. 91) ; crops were damaged at Hulver in 1838, and at Cove- 

 hithe (Curt. Farm Ins. 59) ; Bloomfield found it commonly at 

 Rendham about 1850 ; Smith, abundant at Lowestoft ; Tuck, at 

 Southwold and Aldeburgh — he noticed that the autumn brood 

 consists mainly of males (Trans. Norf. Nat. Soc. 1902, p. 331). 

 It has occurred to me mainly at Southwold in July, 1901, and 

 I have never seen it out of the county {rf. McLachlan on its 

 scarcity, E. M. M. 1901, p. 128). Singly it occurred at Tudden- 

 ham at the end of August, 1900, and at Claydon in the foUowmg
