110 THE EXTOMOLOGIST. 



Time of appearance: — "Jmiiu'?." Size of moth: — "Von der dritten 

 grosse." Common or rare: — " Etvvas setteii." 



A running translation of these would be : — 



1. P. wnnoglypha. " Partly bhiish, partly light, partly dark, grey, with 

 a I,atin W on the hind margin." "In the rifts of fences and trees." 

 " June and July." " Of the second size." " Rare." 



2. P. matnra. " Brownish grey, with white and light yellow markings, 

 which are generally surrounded with l)rown. Hind wings li^ht yellow, with 

 a broad brown margin." " At the leaves of the oaks." " July." " Of the 

 second size." " Very rare." 



o. P. cursorid. "Yellowish grey, with two brown curved and toothed, 

 and two grey wavy transverse lines." " In the rifts of the fences." 

 " June." " Of the third size." " Rather rare." 



The "partly bluish" of monnglypha refers, I should imagine, 

 to tlie slight iridescence we find on some specimens. 



Matura " at the leaves of oaks." This is strange, but 

 probably the few specimens ("very rare'") that Hufniigel had 

 seen were attracted thither by " hone3'-dew." 



Cursoria. "June." A very early date. I doubt whether it 

 ever occurs in Britain so early, although I have captured its 

 congener, tritici, as early as June 29th and as late as September 

 12th, at Deal. 



My only idea of publirshing these descriptions is to convince 

 some of my friends that Hufniigel's descriptions really exist, and 

 there is little doubt in my mind that Staudinger was right in 

 making use of them.

LIFE-HISTORY OF GEOMETRA PAPILIONARIA. 

 By George J. Giupes. 



In expanse of wing and beauty this Geometer is undoubtedly 

 pre-eminent among our emerald moths, and well worth the 

 trouble of rearing, not only on this account, but on that of its 

 belonging to a somewhat numerous species of Lepidoptera that 

 pass the winter in a larval state. 



I have several times succeeded in rearing this insect through 

 all its phases of existence, but not till lately have I taken any 

 real interest in noting its life-history. 



The ova are laid chiefly on birch early in July. At first they 

 are of a pale straw-colour, changing in about ten days to orange- 

 red, and to a bhiish black on the emergence of the caterpillar, 

 which occurs between the middle and end of the month. 



The larva is black when first hatched, and about an eighth of 

 an inch in length. Before hybernation the young caterpillars 

 leed up on the cuticle of the foliage, the denuded parts having a
