278 HEMIPTERA-HOMOPTEKA. 



infests animals, it is said, as well as man, and breeds in dust 

 and dirt. Although a number of species of Heteroptera are 

 more or less harmful, only two need be mentioned here — 

 namely, the Needle-nosed Hop-bug {Calocoris fulvomaculaius) 

 and the Capsid Bugs attacking fruit {Orthotylus marginalis, 

 &o.). 



The Needle-nosed Hop-bug (Calocoris fulvomaculatus). 



This bug attacks the hop in all three of its stages, but especi- 

 ally in the larval and adult phase of life. C. fulvomaculatits 

 is a bug about one-third of an inch in length and tawny-grey 

 in colour ; the young are reddish-brown to chocolate and yellow 

 and green (fig. 159). They lay their eggs in the hop-bine, and 

 hatch out about May. Currants are also attacked by them. 

 They are extremely active, dodging round the poles and bine 

 with great dexterity, and fall readily to the ground when the 

 bine is shaken. They suck the sap from the bine generally 

 at the top, and cause such loss of sap that the upward growth 

 ceases, and numerous low laterals are sent out. When they 

 become winged about July they seem to leave the hops, but 

 many deposit their ova upon wild hops. They hibernate in 

 the larval stage. 



Prevention and RemeOie.'i. — Early washing when the bugs are 

 in the wingless state and jarring over tarred boards held on 

 each side beneath the bine, together with the destruction of 

 bine after a bad attack, will considerably check their increase. 

 We never see this or Frog-fly attack in gardens where string 

 and wires have sirperseded poles. The more soap and tobacco 

 in washes for these hardy bugs the better ; any wash is useless 

 for the winged adults. 



Lice (Anoplura). 



The Lice are generally called Peiliciilidir. These noxious 

 creatures are now considered degenerate Hemiptera. They all
