46 THE entomologist's RECORD. 



BATCH OF EGGS. — In July, 1907, I divided with a friend the ova laid in 



a cage by a (Swiss) female Araschnia Icrana. When we returned to 

 England, my larvte were kept in an unlieated greenhouse, and pupated, 

 duly emerging in the spring of last year as the form Icrana. My friend 

 kept his larva:' in a warmer house tha.n I did mine, and they pupated 

 quite a fortnigbt earlier, and all emerged in September as the form 

 prorsa, except one individual, which passed the winter in the chrysalis, 

 and emerged in the March following as a typical Icvana. — W. H. St.

:i^OTES ON COLLECTING, Etc. 



Pairing Habit of Petasia cassinea.— I have frequently found pairs 

 of this species on trunks of trees, but have never noticed the habit 

 referred to by Mr. Rothschild. I think his must have been an excep- 

 tional case. — Edward Goodwin, F.E.S., Canon Court, Wateringbury

SCIENTIFIC NOTES AND OBSERVATIONS. 



Nonagria neurica, Hb.^edelsteni, Tutt (Ent. lice, xx., p. 164). 

 — At the end of November last, I sent to Mr. Tutt, for publication in 

 the Entumolof/ist's Ilecord when space should permit, a note, pointing 

 out that the continuous chain of historic evidence from Hilbner's 

 figure, through Treitschke's statement and Schmidt's determination, 

 down to Staudinger's examination of Ochsenheimer's collection, was 

 in favour of the ordinary continental usage of the name neurica, and 

 that, therefore, according to the well-known law of prioritj^ Mr. Tutt's 

 new name of cdchtcni was unnecessary, and should sink as a synonym. 

 As an exhaustive note on the subject {f'.nt. lice, xx., 286-293) was 

 already in the printer's hands, and has since been published before 

 space could possibly be found for my note, the last-named would now 

 be out of date, and our editor has ver}'^ courteously given me 

 an opportunity of substituting something more to the point. As 

 Mr. Tutt objects to being bound in this instance, by history or 

 tradition, the question for him resolves itself practically into that 

 numbered (1) on p. 292 — which form does Hiibner's figure best 

 represent ? That it does not represent either accurately we all agree. 

 But, so far as is at present known, the "white collar" seems less 

 variable than the exact character of longitudinal wing-markings, and 

 Hiibner's figure does show the white collar. It is unfortunately 

 slightly misplaced, but would represent no known marking of any form 

 of arundincta, Schmidt. The argument from the underside is nega- 

 tive, for, as Mr. Tutt saA's, it is not shown ; and it is just here that I 

 do not consider Treitschke's clear statement beside the mark. Ochsen- 

 heimer would probably have seen in Mazzola's collection the very 

 specimen figured by Hubner, but as there is no proof of this, I bow to 

 Mr. Tutt's opinion that capital cannot be made out of it ; but the 

 fact that Treitschke mixed up the two species is incontrovertible. 

 I believe some continental authorities who are better acquainted 

 with cdehteni, Tutt, than we are, consider that the build of Hubner's 

 figure is nearer to this th&n to ar a ndineta, and Mr. Edelsten has pointed
