GRANARY WEEVILS: S. GRANARIUS AND 8S. ORYZ. 45 
most abundant and most destructive insects. As far as my own 
experience goes S. oryz@é is by far the commoner of the two. 
These weevils are frequently accompanied by many other 
Coleoptera belonging to different families, the economy of which 
is little known. Curtis mentions five species as so found, viz., 
Silvanus surinamensis, L., Cucujus testaceus, Fab., Ptinus crenatus, 
Fab., Uloma cornuta, Fab., and Trogosita mawritanica, L. I 
have met with fifteen. Four of these and a near ally of another 
are mentioned by Curtis—the large black carnivorous T'rogosita 
mauritanica, of which I found two or three specimens in the 
spring; the abundant and variable little Silvanus surinamensis ; the 
much less common, large, reddish Uloma (Gnathocerus) cornuta, 
and the active, flat, brown Lemophlwus ferrugineus, Steph.— 
Curtis’s Cucujus testaceus—which, except in one instance, was not 
generally common. In November, 1878, I found a specimen of 
the somewhat spider-like Ptinus fur, L., crawling on the glass of 
one of-my stores, in which nothing had certainly been introduced 
since the previous autumn, so that it must have bred there. In 
addition, I have found the lttle Brachelytrous Stenus wnicolor, 
Er. (= brunnipes, Waterh. Cat.), but only one specimen, which 
probably got in by accident ; it is micro-insectivorous: the round, 
shining Gibbium scotias, Fab., was also probably an accidental 
visitor, as were certainly the few specimens of Coccinella bipunc- 
tata, L., which were found; the dark brown, elongate, cylindrical 
Rhizopertha pusilla, Fab., was very abundant; the pretty oval, 
four-spotted and lively Alphitophagus 4-pustulatus, Steph., only 
occurred in one store, but then commonly; the two red-brown 
Tribolium (Stene) ferrugineum, Fab., and T’. confuswm, Duval., 
occurred generally, as did the more shining Hypophleus 
depressus, Fab.; the well-known Tenebrio molitor, L., was found 
occasionally, and its “meal worms” are still feeding away in two 
or three of my stores. ‘The samples were not all of equal quality; 
for instance, No. 1 contained S. oryze, R. pusilla and Silvanus 
very commonly, 7. ferruginewm rarely, and a few of L. ferru- 
gineus, but no S. granarius. No. 2 contained S. oryze most of 
all, R. pusilla very abundant, T. confuswm a good many, and 
G. scotias one or two specimens, a few S. granarius, but no 
Silvanus, and no L. ferrugineus. No. 3—the Stambourne store— 
seemed to be altogether different ; here was H. depressus instead 
of Tribolum, S. granarws instead of S. oryze, together with A.
