identified as the Betliylid, Pristocera ormifera, Say. During its larval 

 existence it attacked and destroyed a second host. Pupation took 

 place in a silky cocoon and this stage lasted thirty-three days.

CJiolus cattleyarum, sp. n., found on Cattleya mossiae, is described. 

 It has done considerable damage to these orchids in a greenhouse in 

 Milwaukee and probably came from Colombia or northern Brazil.

From observations made in 1915 with regard to the occurrence of 

 Heterocordylus malinus, Rent., and Lygidea mendax, Rent., on apple, 

 €rab apple and Crataegus, the former was found to be fairly abundant, 

 occasional or absent on apple and wild crab and very abundant on 

 Crataegus, while the latter was very abundant in two cases on apple 

 and wild crab, but very rare on Crataegus. This points to the apple 

 being the chief food-plant of L. mendax and to Crataegus being that of 

 H. malinus.

In this full and complete account of Lygus prafensis, L., a list is 

 given of about fifty plants of economic value that are attacked by it. 

 It has also been proved to be capable of transmitting fire-blight. 



A detailed account of the hfe-history is given. The natural 

 enemies of the bug include a minute Mymarid parasite, Anagrus 

 ovijentatus, Cr. & Leon., which is described, and some birds. The 

 injury done to peach stock is described and illustrations of other plants 

 injured by it are given. 



Numerous methods of control are discussed. Its control on peach 

 nursery stock presents peculiar difficulties, as the injury is done in a 

 a few days by the active, winged adults that invade the peach orchards 

 in countless swarms from surrounding meadows. As they take 

 flight at the slightest alarm, they are practically impossible to reach 

 with a spray, besides which their integument is highly resistant to 

 the strongest contact insecticides that it is possible to use on peach 

 foliage. 



A series of experiments with soap, nicotine, kerosene emulsion, and 

 asafoetida are described, none of which appears to be effective ; also of 

 dusting experiments, the use of sticky shields, suction apparatus and
