Stephens’ description, and has been, and probably correctly, 
referred to 1. preustus, Fab. 
Elater miniatus is at once distinguished from this species, or 
from any other species except Hlater sanguineus, Lin., by the fact 
that the thorax is clothed with black pile, and that the elytra are 
red, without the least sign of black tips. From E. sanguineus, I 
imagine the size alone is sufficient to separate it, and no one has, 
as far as I am aware, referred it to that species. 
Although Rye appears to have received small specimens of 
E. lythropterus from the New Forest, from Turner, I have not my- 
self seen such. H. miniatus, under the name of ‘‘ pomone,’ is now, 
according to my experience, the commoner species near Brocken- 
hurst, where I have obtained it from Mr. Gulliver, and have also 
met with it on several occasions, but it is (as indeed at the 
present time any “red Hlater” is) far from common. Nine 
specimens are now in my collection, and I may have given away 
one or two; and these are all I have obtained, and I have not 
seen it from other places. Mr. Rye considered this was the 
Species obtained by Hardy in Sherwood Forest. In the face of 
the fact that neither Candeze nor Seidlitz recognised this as a 
new species, if indeed they have seen specimens of it at all, and 
that (see Rye) Thomson referred it to pomorum, I think any 
statement-as to its occurrence on the continent will require 
corroboration. The sculpture of the thorax—which in LE. lythro- 
pterus is a close, almost confluent somewhat granular punctuation, 
but here is a much more sparse, distinct puncturing, with a 
shining smooth interstitial surface—will probably be found of 
most use in separating it from other allied species. It should be 
also observed that Stephens expressly says his “ pomone’”’—and 
which appears to be a single specimen of H. preustus—came 
from Darenth Wood. Barmouth is only given on Hope's 
authority, and may of course refer to some other species. I 
have not myself seen any other example of the true H. preustus, 
which is, at all events, a very scarce species in this country.

INDOOR LIGHT. 
By Masor Joun N. Sruu, F.E.S. 
Ir is not to be supposed that this form of using light, as an 
attraction for insects, is equal to systematically arranged outdoor 
light; at the same time, it has many advantages over the latter. 
There are some persons who can with safety employ indoor light, 
who dare not, for various reasons, venture to stand about in woods, 
fens, or under lamp-posts by night. Besides, the convenience of
