GROUP F. 
Insects in Furniture. 
The furniture and household pests sent by a correspondent from 
Whitchurch, Glamorganshire, belong to two, not three, species as 
mentioned in his letter. 
They are (1) the so-called “ Death Watch” (A tropos divinatoria), 
(the same name is given to certain furniture beetles — Anobium 
tessellcctum, etc.), and (2) mites belonging to the genus Glyciphagus, 
and are probably Glyciphagus cursor, de Geer, and G. domesticus, 
de Geer. (Specimens were sent to A. Michael, Esq., for identification. 
They proved to be G. domesticus, de Geer.) 
They are both best destroyed by fumigation. Sulphur is usually 
employed, but if both the pests are particularly abundant, the rooms 
should be fumigated with hydrocyanic acid gas as well. Rooms 
should be well brushed down and the floors washed with soap and 
water. Books, etc., which harbour the Atropos should be subjected 
to the fumes of benzine in closed boxes. Fumigation with sulphur 
answers best for the mites, but is not so effective upon the Atropos, 
hence hydrocyanic acid gas is mentioned. 
The Saw-Toothed Grain Weevil. 
( Silvanus surinamensis, Linn.). 
Some insects sent by a correspondent of the Board as abundant 
pests in all kinds of corn and meal, in a meal room, were — (1) The 
Saw-toothed Grain-Beetle ( Silvanus surinamensis, Linn.), and a few 
of the Corn Weevil ( Calandra granaria). The latter pest has been 
mentioned in previous Reports and a note upon it will be found 
in the Journal (Yol. YIII., No. 3, p. 358, Dec. 1901). 
The Saw-Toothed Grain Weevil (Fig. 27) is one of the commonest 
pests in grain, groceries, meal, and almost all edible stores. Although 
it is mainly omnivorous, it has a strong liking for cereals and farina- 
ceous substances. It is recorded as attacking amongst other things red 
pepper, mace, yeast, tobacco, and preserved fruits. Bags in which meal 
flour, etc., are kept may be perforated by them, and in one instance
