In order to get pictures of the bugs laying eggs, it was found that 

 time could be saved by caging them for two days on leaves only, and 

 then placing them on suitable branches before the camera. They are 

 usually ready and anxious to deposit eggs by that time. 



Females were observed ovipositing on the trees as late as July 18. 

 Specimens were still on the trees July 22, but most of them disap- 

 peared with the cold rains that followed. A search was made on July 

 27 but no specimens were obtained on trees where they had formerly 

 been abundant. This species was found numerous on hawthorn and 

 wild crab along with H. malinus at Portage Falls, N. Y. The species 

 has also been found breeding on quince trees. 



The False Tarnished Plant-Bug {Lygus invitus Say) 



This Capsid causes serious injury to pears, and is well described in 

 a bulletin by Parrott and Hodgkiss (1913). The nymphs of this species 

 have been found abundant on pear branches where they injure the 

 fruits, but no records exist giving the time when eggs are laid or where 

 they are placed. 



This species is perhaps the most difficult in which to observe ovi- 

 position of . eggs. Several females were kept in cages on pear branches 

 but only one individual was observed to oviposit. This observation 

 was made on the morning of June 26. Other females which were heavy 

 with eggs were observed daily to feed on pear fruit and on the branches 

 but no effort was made to oviposit. The female observed to oviposit 

 was first discovered when the ovipositor was inserted nearly to its base 

 in a fresh pear shoot of the present year's growth. After two minutes, 

 the ovipositor was withdrawn. The female turned, inspected the hole, 

 then moved along the branch about two inches. After five minutes, 

 she became very active and proceeded along the branch feeHng with 

 antennae and beak. She soon returned to the spot where eggs had been 

 placed before, and with proboscis to mark the opening, she raised up, 

 unsheathed the ovipositor and made the insertion much in the same 

 manner as observed in the case of apple red bugs. A period of two 

 minutes elapsed before the ovipositor was withdrawn. Upon examin- 

 ing the branch,, it was found that six eggs had been laid in a space 1 

 mm. long. The eggs were closely packed in a double row lying flat 

 just within the cambium layer (Fig. 8, pi. 12). Three of the eggs were 

 injured in opening the cavity, thus they do not show well in the photo- 

 graph. Of two eggs measured, the length is 1.05 mm. by .26 mm. 

 wide. 



The nymphs and adults of L. invitus were found most abundant on 

 a row of Bartlett pears very close to a hedge-row of young elms and 

 black locust. On June 5, the nymphs were found on both the pear 

 and elm branches. Adults were reared from nymphs captured on the
