“The British species” (of the family Bosrricnip™) ‘are 
few in number, of small size, and considerable rarity ; indeed 
it is not improbable that some of them are not really in- 
digenous, but have been imported in timber, ete., from abroad, 
as in the instance of Dinoderus ocellaris, described by Mv. 
Stephens, from my collection, which I found floating in a 
cup of coffee.”— Westwood, Int. Mod. Classif. Insects, L., 
p- 278 (1839). 
Professor E. B. Pouuron, F.R.S., read the following note 
on “Heliotropism in Pararge and Pyrameis,” communicated 
by Dr. G. B. Lonesrarr, M.D.:—“Following up my observa- 
tions on the attitude at rest of Pararge schakra, Koll., made 
near Simla in October 1903,* I paid a good deal of attention in 
February and March of the present year to P. meone, Cram., a 
butterfly that I found in varying numbers in all the parts of 
Algeria that I visited. This is either a southern form of P. 
egeria, L., or a closely allied species in which the yellowish 
spots are replaced by fulvous. ‘It is fond of settling on sandy 
roads, rocks, walls, or the leaves of trees or shrubs, compara- 
tively rarely visiting flowers. It first pitches, invariably if 
might say, with its wings about three-quarters expanded, and 
in the vast majority of cases with its back to the sun, the axis 
of the body being rarely more than 45° to either side; im- 
mediately after settling it more often than not adjusts itself, 
by a quick movement, so as to make its tail point fairly 
accurately tothesun. After thisadjustment, if at all, it closes 
its wings over its back, and as a necessary result its shadow 
is reduced to, or approximates to, a mere line. There can, I 
think, be no doubt that this habit is a great protection to the 
insect, since when resting on fairly flat surfaces the shadow of 
a Satyrine or Nymphaline butterfly with cryptic under-side is 
often more conspicuous than the fly itself.

‘Feb. 8, Guyotville. Watched a specimen settle about 
twenty times. The wings were alwaysat first expanded about
