165 THE entomologist's record. 



out that " the specimens bred by Dr. Corbett from P. aueiipariahalong 

 to the ' spinicohlla group,' with unspotted tarsi, and not to the 

 ' p()nu/oli>'lla gron}^,' 'which mcliidcH tnriiiinella, and has the hmd tarsi 

 dark spotted. The colour of L. aucupariella is also distinctly greyer 

 than that of L. tonnineJla, and the white marks duller and less 

 striking." He states that he has not, however, "been able to 

 make out any satisfactory distinction between L. aumparieJIa and the 

 common, and somewhat variable, L.spinicolcUa, and should be inclined 

 to regard it as belonging to that species, unless there are larval 

 differences suflRcient to separate the two. Dr. Corbett does not 

 mention what the larva of aunipandla is like, and the mere fact of the 

 differentfood-plant does not weigh much." (3) Mr. Durrant points out 

 that Frey says of torminella -. " Hind tarsi spotted or plain." (4) The 

 only references to L. aiicuparidla, that I can find, are : [a) Frey, in 

 describing his ftorbi, says : " ? aucupariella, 8cott." (6) Sang [K.^l.M., 

 xxii., p. 262), who heads a note, " Lithocnlleti.^ sorbi, Frey," and who 

 says [evidently uniting mrbi (as he understood it) and ancupanrlla'] -. — 

 " The identity of the LitJiocolletif> from mountain-ash, generally known 

 as ancujiariella, Scott, has long been rather a sore point with me, as I 

 have always (though almost single-handed) maintained its distinctness 

 from pontifoliella." Sang also found larvaj on Piuiiu.s jiadus, and states 

 in the same note : "A fair proportion of these duly emerged the follow- 

 ing spring, identical with the mountain-ash species. I forwarded them 

 to Mr. Staintou at the end of the season. He told me that the Conti- 

 nental specimens were lighter and brighter in colour, but declined to 

 give any opinion as to their distinctness from L. pnniifolidla. Look- 

 ing over these carefully one day, I noticed for the first time that the 

 tarsi were different from those of L. pinuifolidla, which are pale and 

 ringed with dark, but like those of L. spiniculdla, pale and unicolorous. 

 Now, I never find either L. spinicoldla in the sloe, nor L. pnmifolidla 

 in the hawthorn, on the high grounds where 1 take the mines of L. 

 xorbi. I have been told that mines are common in the S. of England 

 in the mountain-ash, and it will be of interest to hear to which group 

 the moths produced from them belong. There are no mines in the 

 mountain-ash here (Darlington), although L. pomifoUella and L. spini- 

 colella are common enough, the former especially." These specimens 

 from Pnmvs jmilus are evidently the paduella of Hodgkinson, and pro- 

 bably the L. paddla of Glitz. (5) Mr. Richardson further notes : " I am 

 not personally acquainted with L. sorbi, unless Dr. Corbett's specimens 

 are that species, but from descriptions it would appear to be very like 

 L. sjnnirolella. Mr. Stainton's statement that Continental specimens of 

 L. svrhi, Frey (= aucupariella, Scott?) are lighter and brighter than 

 the North of England aucupariella, Scott ( = sorbi, Frey ?) on moun- 

 tain-ash and Prunus padus, together with the strong resemblance of 

 Dr. Corbett's specimens to L. spinicolella, rather suggests that we may 

 not have the true L. sorbi, Frey, at all in this country, but that this 

 mountain-ash Lithocolletis, is either a third (unnamed ?) species, or 

 merely />. spinicolella on a new food-plant." (6) To this one is inclined 

 to suggest that L. sorbi, Frey, has never yet been shown to occm' 

 in Britain, and that we have not yet obtained that species 

 in this country. It is also just possible that Sang's specimens 

 from Prtuius padus (= Hodgkinson's L. paduella) and Ihjrus aucuparia 

 (= Scott's aucupariella) are not identical, as Sang suggested, and,
