BED-BUGS AND FLOWER-BUGS. oo 
a 
safer substance to use is Pyrethrum. In case of a badly infested 
room it should be thoroughly cleaned; fumed with sulphur; the 
walls repapered, kalsomined, or whitewashed; and the wood- 
work repainted. In travelling where one is forced to lodge at 
places infested by this insect, or by fleas, protection from them 
can be had by sprinkling a small quantity of Pyrethrum, (Insect 
powder), between the sheets of the bed on retiring.” 
Upper wing cf Anthocorina. 
In the sub-family of Flower-bugs, (Anthocorina), we find 
insects whose wings are always fully developed. The species are 
all small, and usually so well hidden in flowers, upon trees, and 
under bark and rubbish, that they are not readily seen. Yet 
some species are very common, and being predaceous, they are 
of some assistance to the farmer and fruit-grower. 
Fic. 44.—Triphleps insidiosus Say. After Riley. 
The beak of these bugs is three-jointed; the antennz are 
four-jointed; the tarsi three-jointed; and the ocelli are present. 
Triphleps insidiosus Say, (The Common Insidious Flower- 
bug), illustrated in Fig. 44, is frequently found in company with 
the chinch-bug, upon which it preys, and for which it is some- 
times mistaken. It is otherwise beneficial because eating small 
insects, and it is of a very common occurrence in and among 
the galls formed by the grape phylloxera upon the leaves of wild 
and some cultivated grapes.
