BUGS, FROTH-FLIES. 57 



The Homoptera have wings of the same texture throughout, held 

 roof-like when at rest. This sub-Order includes the Cicadas, Froth- 

 flies, Aphids, &c. A small series of specimens will he found in 

 Drawers 9-16 in a cabinet on the West side of the gallery. 



The Common House Bug {Cimex lectularius) feeds on moisture 

 drawn from pine wood, hence it is often found breeding behind 

 pictures left undisturbed and behind wainscots. This species is not 

 met with in England away from houses, but three species {Cimex 

 colombaria, C. Mrundinis and G. pipistrelli) are found in the nests 

 of pigeons, swallows and bats respectively.
