Besides seven species, of which the hosts are already known, two 

 more parasitic on the larvae of Lepidoptera are recorded, namely, 

 Exeristes albicincta, Mori.", parasitic on Clania variegata, Cram., and 

 Phytodiaeius captiae, Mori., parasitic on Homona rnenciana, Wlk.

 on their food-plants, distribution and the degree of injury for which 

 they are responsible. 



Okuni (T.). Insects Injurious to Poppy in Formosa, II.— Bull. Agric. 

 Expt. Sta., Government of Formosa, no. 142, 1921. 



In the fields of the experiment station, the author has observed 

 various important facts concerning the mode of infestation by the 

 poppy thrips and the best method of preventing the damage it does. 

 He found from field experiments that the thrips are transferred to the 

 poppy flowers by bees, which are attracted by the colour of the petals, 

 whereas the capsule, with the petals removed, is quite free from the 

 insect and ripens normally. It is concluded, in consequence, that 

 removal of the petals at the proper time, within an hour or two of 

 blooming, is the only method of preventing the attack of the thrips. 



SoNAN (H.). The Feeding Habit of Asopinae.— A'o;u/»/ Sckai [The 

 Insect World], xxv, no. 291, 1922. 



The author has observed the feeding habits of two Formosan 

 Pentatomids, Cazira verrucosa, Westw., and Canthecona furcellata, 

 Wolff, in detail, and has come to the conclusion that both species 

 are beneficial to agriculture as they are predacious, like the other 

 bugs of the subfamily Asopinae ; the former attacks Coccinellid 

 and Chrysomelid beetles and the latter the larvae of Noctuids.
