ANTHROCERA TRIFOLII. 48? 



The ab. orobi occurs generally in Belgium, England, France, and 

 Germany with the type. In Switzerland, according to Frey, it is rare. 

 He only gives Trafoi (Wocke) as a locality. 



/3. ab. obscura, n. ab. — A specimen from England (coll. Battershell-Gill) with 

 the spots and inferior wings brown, but with a tint a little paler than A. filipendulae 

 ab. chrysanthemi and A. hippocrepidis ab. nigricans. In coll. Oberthiir [Oberthur, 

 Var. chez L6p., PP- 43-44 (1896)]. 



Webb records (Ent. Bee, i., p. 33) a specimen of this form as 

 being in the Eobertson collection, Liverpool, also a second doubtful 

 one in Mason's collection, Burton-on-Trent. 



y. ab. semilutescens, Higgs, "Ent. Eecord," i., p. 12. — Base of hind-wings 

 orange. 



5. ab. intermedia, n. ab. — With the spots of the fore-wings and the hind- wings 

 of a dull orange colour tinged with reddish (not deep crimson, like the type). An 

 occasional subform of intermedia has the spots of the fore-wings normal, but the 

 under-wings orange-red, as in the latter form. 



We do not feel at liberty to extend the unsatisfactory diagnosis of 

 Higgs' semilutescens, otherwise it should, perhaps, be united with this 

 form. Bond- Smith records specimens of intermedia, from Gamlingay, 

 July, 1891. Christy notes it as rare at Emsworth ; he further notes that, 

 from a batch of eggs laid by an intermediate ? in 1895, he bred 200 

 examples, all typical red ones. In our own series are specimens from 

 Wye, New Forest, etc. The red tinge, in some examples, is re- 

 duced to a minimum, and, in one individual from Wye, the left 

 side bas a blue-tinged fore-wing, with orange-red hind-wing, whilst 

 the right side has a green fore-wing and crimson hind-wing ; the left 

 side shows a distinct failure of development, suggesting that the blue 

 ground colour to the fore-wing, and the orange-red hind-wing, are 

 both less specialised conditions than the green and crimson. South 

 notes specimens with the hind-wings and spots on fore-wings, orange- 

 red, taken in Middlesex in 1893, and Bristowe exhibited, at the meeting 

 of the South London Entomological Society, October 27th, 1892, 

 specimens intermediate in colour between the red and yellow forms. 



e. ab. lutescens, Ckll., " Entom.," xx., p. 152 (1887); Tutt, "Young Nat.," ix., 

 p. 152 (1888) ; Higgs, "Ent. Eec," i., p. 12 (1890).— Anterior wings with the 

 ground colour normal, but with the usual red spots and the hind- wings of a clear 

 yellow colour. 



Cockerell, in naming this aberration, simply gives the reference 

 " Entom., 1878, p. 102." Turning to this, we read that Wellman 

 " exhibited some yellow forms of Zygaena trifolii, reared from larva3." 

 Bond- Smith describes certain Gamlingay specimens (probably palustris), 

 caught July 16th, 1891, and bred later, as being of a " beautiful lemon- 

 yellow, showing no trace whatever of red." This aberration has been 

 recorded from Malpas, in Cheshire (Walker), Emsworth, where 100 were 

 obtained in May, 1893, and 11 in 1894 (Christy), Upton St. Leonards 

 (Higgs), Chattenden (Tutt). 



f. ab. basalis, Selys, "Ann. Soc. Ent. Belg.," 1872, p. lix ; Ibid., 1882, 

 p. cxiii. Trifolii, Hb., "Eur. Schmett.," fig. 134 (?1818). — The two median 

 spots united, and confluent with the basal only, the apical spot being separate ; this 

 last aberration is less common than the others (minoides, glycirrhizae, etc.). 



Generally distributed with the type and other common aberrations 

 in Belgium, Britain, France, Germany, etc. 



rj. ab. glycirrhizae, Hb., " Samm. Eur.," ii., fig. 138 (? 1818) . Glycirrhiza, 

 Freyer, " Neu. Beit.," p. 116, pi. 164, fig. 3 (1836); Selys, "Ann. Soc. Ent. Belg.," 

 1872, p. lviii ; Ibid., 1882, p. cxiii. — The original figure represents a ? of the large 

 form. Anterior wings with the two basal spots united into one blotch, and 3 + 

 4 + 5 into another ; the spots of a dull reddish colour. The hind-wings normal, 

 except that the crimson is inclined to orange at the base.
