number of the weevils will be found dead. 
I. Thorax with very large, diffuse, oblong punctures; colour 
unicolorous, pitchy-ferruginous or pitchy-black ; average size

C. GRANARIA, D. 
C. oryzm, L. 
Cc. granaria, L. Pitchy-black or dark ferruginous, antenne and 
legs ferruginous; oblong, rather depressed; rostrum moderately long, 
slightly curved, dilated a little in front of base at the insertion of the 
antenne ; thorax about as long as elytra, gradually narrowed in front 
and constricted before apex, with very large oblong punctures placed not 
very closely together; elytra with deep punctured striw, interstices 
narrow, alternate ones somewhat raised at base; breast very coarsely 
punctured, L. 2-35 mm. 
Male with the rostrum shorter than in female, and the metasternum 
and abdomen slightly impressed at base. 
In granaries, bakers’ shops, &c. ; widely distributed and only too common through- 
out the greater part of the kingdom. 
C. oryze, L. Very like the preceding, but on the average consider- 
ably smaller, and easily distinguished by its colour, which is pitchy 
with two reddish spots on each elytron; in light examples these spots are 
not very apparent, but the species may easily be known by the punc- 
tuation of the thorax, which is closer, with the punctures smaller and 
rounder ; the striz of the elytra also are more strongly punctured and 
the interstices are narrower, and are furnished with very short yellowish 
bristles. L. 2-3 mm. 
In rice and grain of various sorts; not so common as the preceding but widely 
distributed in various parts of the kingdom; Scotland, occasional, Forth and Solway 
districts ; Ireland, near Dublin. 
I have specimens of a third species, smaller than either of the pre- 
ceding and of a reddish testaceous colour; they are, however, evident 
importations ; the same may perhaps be said of C. oryze, but { have 
thought it best to include the species. 
COSSONINA. 
This tribe may be distinguished from the Calandrina by the fact that 
the pygidium is entirely covered by the elytra and the thorax is less, 
and the elytra more, elongate ; the form is cylindrical and the colour 
uniform, varying from pitch black to ferruginous; the antenne are 
usually inserted at or in front of the middle * of rostrum and not nearly_ 
at base as in Calandra, and the scape of the antenne scarcely reaches 
* This does not always hold good: in the male of Rhopalomesites Tardyi, the 
antenne are inserted just before base.
