208 THE ENTOMOLOGIST. 



makes no reference to anj' offer of Artemisia to the later brood 

 of larvae. 



Stange (Stett. Ent. Zeit. xlvii. 281) also records some 

 personal experiences of innotata, of which he bred a few ex ovo 

 on Artemisia vulgaris, which hibernated as pupse, and one from 

 a beaten larva from rose, which emerged on August 4th the 

 same year. He inclines to the view of Rossler " and Speyer " 

 {iibi?) that all three of the group are modifications of one 

 species. 



Milhere (Ann. Soc. Lyon xix. 30, 31) has brief notes on all 

 the three larvfe of the group ; he treats tamarisciata as a valid 

 species (larva uniform light green, on Myricaria germanica, and 

 not varying), '\fraxinata of the English" (which he found in 

 June, 1863, on Corlaria mijrtifolia) as well removed from innotata 

 by the form and colour of the larva (green, excepting the vinous 

 anal flap), but perhaps only a variety of tamarisciata. 



The British form of innotata larva is described by Helhns 

 (Ent. Mo. Mag. xxi. 137) under the title of " an enigma," the 

 solution being given later in notes by Warren and by Hellins 

 himself (Ent. Mo. Mag. xxii. 257, xxiii. 115, xxiv. 10) ; Hellins' 

 notes, with a later description by Buckler, are given in full 

 in Buckler's ' Larvae,' viii. 35, and a figure added, pi. 136, fig. 6. 

 The usual British form seems exceedingly different from the gay 

 green, red-marked form which is prevalent in Germany, Southern 

 France, &c. ; but Warren says his British examples were variable, 

 and I have already mentioned that the Continental are extremely 

 so. The one or two larva I have myself found (at Sandown, on 

 Artemisia vulgaris) agreed, so far as I can recollect, with Hellins' 

 description and Buckler's figure. Barrett records (Lep. Brit. ix. 

 105) that Mr. Robson, of Hartlepool, has found and reared 

 E. fraxinata on flowers of scabious; probably Mr. Robson knew 

 the larva, otherwise one would be inclined to refer the record to 

 innotata, as both occur at Hartlepool. 



Dr. Draudt, in describing the eggs of E. innotata (' L-is,' 

 xviii. 315, pi. vii., fig. 4), says that that of " var. fraxinata, 

 Crewe," is entirely like it, and that the same can probably be 

 said of "var. tamarisciata, Frr." Perhaps the genitalia will 

 throw some further light on the subject. Schroder's elaborate 

 description and figure of the apparatus in innotata (111. Zeit. 

 Ent. V. 305) is purely anatomical, and does not deal with the 

 allied forms. 



HL — Denotata, Virgaureata, &c. 



A pair of species whose probable specific identity has hardly 

 been at all discussed are E. denotata, Hb. {cajnpanulata, H.-S.), 

 and jasioneata, Crewe. The British forms look so very distinct 

 in the imago state that, although Crewe noticed the great 

 similarity of the larvae, and the botanical relationship of the
