BKITISII SPECIES OF LITUOCOLLETIS OF THE SPINICOLELLA GROUP. 1G7 



further, that the hitter may, as Dr. Wood aud Lord Walsin^'ham have 

 su<,f.ii:ested, be a northern form of 7.. tonniiuila, rather than of L. spmi- 

 culclla. 



111. — llaviuj,^ reaehed tliis stage, I was so far interested in the suh- 

 jeet, that I sent on to Lord Wulsingham and Mr. Durrant the speeimens 

 standing in my eabinet under the name of L. sorhi. These were : — 

 J — Two specimens from Coverdale's collection. 

 2. — Ten specimens bred by Sang in ISii'A and LS84. 

 3, — Six specimens from one of the Darlington collectors (New- 

 man or Millraru), 1885. 

 4. — Six specimens from ditto, 1886. 

 5. — Six specimens from Dr. Corbett, larvaj, Selby, 1896, bred 18it7. 



Sir. Durrant writes : " Lord Walsingham and myself have examined 

 your LithocoUetids with the following results : — 



" 1. — The two specimens from Coverdale, labelled ' sorbi,' agi-eewith 

 specimens received from Bower as tdrminella. These are tartiiinella. 



"3. — Darling-ton, 1885, six specimens. Lord Walsnigham con- 

 siders the fourth specimen as doubtfully agreeing with the other five. 

 This series (with the exception of No. 4) is pomondla [tlejlexella), Stn., 

 Zuol. = sjiiniroIeUa. 



" 4. — Darlington, 1886, six specimens, Nos. 1, 3, 4, 5 = pomunella 

 {siiinicoldla), Stn., Zool. = Kpinicolella. Nos. 2 and 6 = pomonella 

 (dejle.iella), Stn., Zool. = spinicoIeUa. 



" 5. Selby. Six specimens from Corbett, bred 1897. These are the 

 same as (2) the ten specimens labelled ' sorbi, Sang, 1883-4.' These are 

 identical with two Merton specimens, from Pi/rm aumparia. These are 

 what wc call aucuparicUo, Scott, ]\IS., and appear to be a northern form 

 of L. tonuindla, which differs from the southern forms on the gradual 

 lines suggested by PohjommatnH antrarclie {ty\)\i.ymgi\\ii European form), 

 sahiiacis and arta.vcr.vca. 



" An examination of the genital organs seems to Ijc required, but 

 we are not prepared to undertake this until the larvte have been more 

 particularly described. So far we have not seen an English specimen 

 agi'ceing with the Continental .wr6/, Frey " (m litt., July 13th, 1897). 



IV. — Wocke's synonymy {Catalo;/ der Lepidop., 1871, p. 330) of this 

 group works out as follows : — 



2Ho6.—Sor1)i. Frey, Mittlieil., 1852,608; Tin., 338. Sorbifoliella, B.-S., v., 

 p. 328. PomondUi, H.-S., 775-6.— Larva : Sorhus aiicuparia (inf.). — Fen., Germ., 

 Hclv., Gal. 



2H^i.—TormiiiclUt, Frey, Tin., .340; Stt., .^hh , 1857, 109; Nat. Hi'st. Tin., 

 ii., 128, T. iii., fig. 1. — Larva : SorJ)ii.f tormiualia (inf.).^Angl., Helv. 



2m7.—Sinnicolella. Sta., Ins. Ilrit. (1854), 271 : Nat. Hi.-<t. Tin., ii., 136, T., 

 iii., tig. 2 ; Frey, 343. Pnini, Frey, .Mittlieil. (1855), 014. Prunidla, H.-S., v., p. 

 326. Pomonella var. .'ipinicolelhi, Zeit. Linn. Ent. (1846 ') i.. 203 (Ann., i.). 

 r>etle.reWi (pomonella), Sta., Zool. (1H51), App. 170 ; Stett. Knt. Zeit. (1852), 81.— 

 Larva: Prnnu.i spino.w et P. domestira (inf.). — Anglia, Germ., Helv., Hung. 



2SoB.—Padellu, Glitz, Jahre.'ih. (1863). 41. Larva: Prnnnx padus (inf.).— 

 Germania. 



V. — It would appear that we may have in Britain not only the well- 

 known species, L. turmindla and L. spinicoldla, but {)robal)ly also /'. 

 pmldla of (Jlitz, a s})ecies, not yet, I believe, acknowledged as British. 

 There is every possibility, in the face of the conclusion of Lord 

 Walsingham and Mr. Durrant, that the insect called aucuparidla, 

 Scott, is not L. surhi, Frey, but that it is identical with the L, sorbi 

 of Sang, and that both are, as Dr. Wood and Lord Walsingham suggest,
