Mr. Smith’s, which held back, and hibernated as a larva. Otherwise, 
the hybernating stage of C. tr uncat a in Arran, has not been put to the 
test, though I presume it is the same as elsewhere ; neither is any in¬ 
formation available as to the hybernation of concinnata. I have some 
specimens of <'. citrata, purchased from the W. Tunsta 11 collection, and 
purporting to be from Arran, though not individually labelled; and 
Mr. Smith tells me that Mr. A. Erskine has taken the species there 
on more than one occasion, “ beaten from trees on which they were 
resting, in the month of August.” 
Thus, as concinnata was clearly neither “ Arran truncata,” nor 
“ Arran citrata ,” in any full sense, I sent a body to Mr. Pierce to 
examine, if haply it might prove a new species. Somewhat to my 
surprise he reported it to be citrata ( = innnanata ). It is only right to 
add that he had already sent me most of his slides, and had only his 
memory and one aberrant Japanese form to guide him. He has since 
sent me up the mount, and it appears to me, though I am open to 
correction in a branch of research to which I am so unaccustomed, 
that the spines on the tedeagus are somewhat more slender, and perhaps 
more numerous. At any rate, they look so manifestly finer than in 
our English citrata (though of the same shape), that I hesitate to think 
of a transposed body, from a true citrata, as the clue to the unexpected 
result ; if it has its right body, concinnata is certainly not a var. of 
truncata. Of course, I shall send further material to Mr. Pierce at the 
earliest opportunity.* 
Geographical Distribution and Local Races. 
Cidaria truncata is recorded by Staudinger (Cat., ed. 3, p. 293) as 
occurring throughout central and northern Europe (excepting Iceland) 
at Bilbao,! in northern and central Italy, Armenia, Altai, eastern 
Siberia, northern Mongolia, Kamtchatka, Amur, Ussuri district,' 
Japan, and western China, with ab. schneideri as a var. in Polar Norway, 
ab. latefasciata as probably a var. in south-east Siberia, and susyectata 
Mosch. ( brunneata, Pack.), as a var. in Labrador. Barrett (Ley. Brit., 
yiii., p. 271) says, “it has an immense range,” and adds India and 
various North American localities to Staudinger’s list. Unfortunately, 
I am almost entirely ignorant of the eastern paEearctic forms. Leech 
(Ann. May. Nat. Hist., ser. 6, xix., p. 668) says, “I obtained the species 
at Nemoro and Shikotan in August, at Nikko in September, and at 
Oiwake in October. All the Japanese specimens of L. truncata in my 
collection, are modifications of the type form varying in two direc¬ 
tions, one graduating towards [var.] cinereata (corussana), and the 
other leads up to a variety in which the basal third of the primaries 
is blackish-brown, intersected by a dingy, rust-coloured band, the 
central fascia is almost white, the apical patch is unusually large, and 
agrees with the base in colour. The form last referred to is from 
* This was done, the evidence of the first specimen confirmed by three others, 
and Di/sstroma concinnata announced as a valid species in The Entomologist's 
Record , xx., p. 143. 
t Bossier (Stett. Ent. Zeit., xxxviii., p. 368) records the Bilbao form as 11 trun¬ 
cata var. immanata.” I have no Spanish forms myself, nor has the British 
Museum ; from Cauterets, in the Pyrenees, I have one large, anomalous-looking ? , 
which might belong to eiihcr specie-, but which 1 regard as citrata.
