wrapped the fruit in paper, twisting it only at the stem end of the 

 fruit, the other end being left entirely exposed and yet the method 

 seemed quite efficacious. Mr. Krauss of Kamehameha School 

 (present as a visitor), stated that to his observation, D. cuciirhitae 

 is less injurious on windy days. The fly being erratic and food 

 quite abundant, even an incomplete covering will suffice to check 

 its ravages. He has also found useful hints in the use of resistant 

 varieties of the fruits liable to attack. Mr, Clark of Wahiawa, 

 and the Kamehameha School, are growing what are known as 

 cherry-and plum-tomatoes which are free from attack by this pest-. 

 This is likewise true of a hard-skinned variety of squash which he 

 is growing. He has also observed that the more extensive a field 

 of a certain crop is, the less subject it is to attack. Mr. Craw 

 stated that certain varieties of cherries in California are known 

 to be immune to the San Jose Scale. Mr. Swezey said that in 

 the course of his inspection work in Ohio he had found that sour 

 cherries and Kiefer pears were always free from San Jose Scale. 

 Mr. Austin has observed that rose bushes which he is growing 

 within a slat house are absolutely free from injury by the Japan- 

 ese beetle, whereas a single twig of this same rose that projected 

 outwardly through the slats had its leaves injured by the beetle. 



Mr. Perkins exhibited specimens and illustrations of certain 

 leaf-hopper parasites {Stylo pidae), which are described and fig- 

 ured in a bulletin soon to be issued, and made some further 

 remarks.''' 



He said that though he had given an interpretation of the mouth 

 parts, different from that of Eaton, he was prepared to find that 

 the latter might be right, or both wrong. Thus it was quite pos- 

 sible that the true mouth was what he called the "foramen" in 

 liis figures. This occupied a half-way position, between those 

 assigned to the mouth opening by Eaton and himself. The study 

 of the puparia and of the parts of the immature insect within, 

 as well as of the parts of the female head in the Xeaini would 

 very likely conclusively settle the point, but he had not yet had 

 time to make the necessary study of these. It was quite clear that 

 the head-parts in the adult males and females, and the less distinct 

 ones in the puparium, could be homologized. 



Mr. Perkins further stated that years ago he had observed that
