46 THE ENTOMOLOGIST. 
4-pustulatus quite common, S. surinamensis and L. ferrugineus 
common, these last two species less abundant than usual, and so 
on. No. 3 was dressed from English wheat which I believe had 
been granaried at Stambourne in North Essex. Dr. Power* has 
kindly named the species for me in all instances. I also met 
with many specimens of an Hemipterous insect in various stages 
* In answer to my queries Dr. Power has kindly written me as follows :— 
“ Cucujus testaceus, Curt., in Waterhouse Cat., is given as the same as ferrugineus, 
but both in Waterhouse and in the modern Sharp’s Cat. the genus Cucujus vanishes, 
and the insects are all Lemophleus. I have taken all the British species, but invari- 
ably under bark, &c., excepting only our friend ferrugineus, so that I suppose is the 
only ‘‘corn-lover.” There is one species most closely resembling it, L. duplicatus, 
but I only know it as a bark insect. Silvanus.—I have taken several species, 
always under bark, or by sweeping, with the sole exception of our surinamensis, 
which is manifestly sitophilous; S. wnidentatus is common under bark, &c., and the 
nearly allied Nausibius dentatus comes with sugar as far asl know. Hypophleus.— 
Other species, as bicolor, castaneus, &c., always in or under bark, but our one 
species, depressus, I have always had from granaries; I never saw it “at large.” 
Tribolium I never saw “at large” ; T’. ferruginewm, one of our species, I used to get 
from granaries at Cambridge; of the other, 7. confusum, I found one or two mixed with 
my ferrugineum, but never saw many till you sent it; 11 is not in Sharp’s or Water- 
house’s Cat.; we used to call the other species Stene ferruginewm in J. F. Stephens’ 
days. Calandra.—I used to get both species from the granaries as you do; as to the 
name, Waterhouse changed it into Sitophilus, but in the more recent Sharp’s Cat. it 
is again Calandra, which I suppose should stand. Alphitophagus I used to get 
from granaries only, as you do, at Cambridge, but have not seen it alive for forty- 
five years until now. Uloma cornuta used to occur in meal, and of course Tenebrio, 
though I also take both species of Tenebrio at large. There is another beetle, 
Niptus hololeucus, which you haye not mentioned, which one constantly finds 
marching about at large, and which I believe to be almost omnivorous, but I had 
once a specimen of corn meal containing it in hundreds. I kept it in a closely 
stoppered bottle which was never opened and for three years it continued to breed, 
developing larvee, pup in a sort of cocoon, and the perfect insect, the numbers 
gradually diminishing. T'rogosita I have taken at large in sandy places, but never 
got it in corn. Gibbium and Ptinus fur I have occasionally found crawling 
about, but doubt their being corn-eaters ; Ptinuws I have found in old skins, &e., in 
animal rather than vegetable matter. Rhizopertha I never took myself, but from 
the appearance of the corn in which it was found I should suspect it of feeding 
upon it; T. Wilkinson and the Scarborough entomologists, who seem to have 
worked largely in granaries, &., used to get a quantity of it. Stenws and Cocci- 
nella are of course accidental. J should think there can be little doubt that Alphi- 
tophagus, Tribolium, Calandra, Uloma, Tenebrio, Niptus, and I think Rhizopertha, 
are actually ‘‘ sitophagous,” but suspect, from the habits of other species of the same 
genus, that Trogosita, Hypophleus and Silvanus may be parasitic. Lemophleus 
clematidis is, I think, parasitic on Xylocleptes bispinus. The behaviour of L. Cle- 
matidis is very like that of Nemosoma elongatum, which I know to be parasitic on 
Hylesinus vittatus, and probably L. ferrugineus is the same with respect to some of 
these corn-loyvers.”
