be extracted witli 1,000 parts of water for 10 days. All samples of London purple 

 examined by the author showed the presence of more than 4 per cent free arsenic. 



Resume of the. searx-h for the ■iialive home of the San, Jone scale in Japan and China, 

 C. L. Marhilt (pp. 6.5-78). — Detailed notes are given on the itinerary of the author 

 throuijh Japan and China. Arguments are presented to show that Japan is not the 

 native home of the San Jose scale. In China the scale was found on native crab- 

 apples and haws and the author believes that the evidence for the origin of the scale 

 in China is very good. It is suggested that the scale may have been carried from 

 China to California on trees imported by James Lick. 



Preliminary report on the importatioti and present status if the Asiatic ladijhird, ('. L. 

 Marlatt (pp. 78-84). — Notes are given on the shipments of ('hilocorns similis made by 

 the author into this country, as well as upon previous importations into California 

 by A. Koebele and into New Jersey by J. B. Smith. The beetles appear to be 

 thriving well in this country, and it is believed that much may be expected from 

 them in the future in the way of destroying the San Jose and other s(;ales. 



I'rcdatory insects inliicli affect the usefulness of scale-feeding Coccinetlidn; C. L. Marlatt 

 (pp. 84-87). — Observations on ladybirds have shown that they are destroyed by the 

 wheel bug, the native and introduced species of praying mantis, lace-winged flies, 

 and by Adalia bipunctata. The wheel bug is considered to be a source of the greatest 

 menace to the introduced ladybird larvte. A parasite, Syntomosphyrum esurns, has 

 also been bred from the introduced ladybirds, but as this species belongs with a 

 group of secondary parasites, it is suggested that the primary parasite may prove to 

 be Iloiaalotylus obscurus. 



On the feeding habits of the adults of the periodical cicada, A. L. (Juaintance (pp. 

 90-94) .—Observations made by the author indicate clearly that both sexes of the 

 periodical cicada puncture trees of various species and suck out the sap. These 

 feeding habits were observed in a number of localities in Maryland, and the trees 

 upon which the cicadas were observed include apple, pear, peach, plum, maple, oak, 

 etc. The beak of the cicada was introduced into the wood for some distance while 

 feeding, and when the insects were captured in the act of feeding and (juickly opened 

 it was found that the alimentary tract was considerably distended with sap. 



Notes from Delaware, E. I). Sanderson (pp. 97-102). — The author presents a brief 

 account of the various species of plant lice on apples, and means for combating them, 

 as well as on the strawberry-root louse, codling moth, periodical cicada, strawberry 

 weevil, and Systena tseniata. 



Notes for the year in New York, E. P. Felt (pp. 102, 103). — Brief statements concern- 

 ing grape-root worm, grapevine leaf-hopper, apple-tree tent caterpillar, forest tent 

 caterpillar, and fall webworm. 



Observations on certain insects attacking pine trees, E. P. Felt (pp. 10.'3-105) . — Notes on 

 Tomicus ccUligruphus, T. pini, Monoliammus confusor, and Dendrocfonus terebrans. 



Egg-laying record of the plum curculio, A. L. Quaintance and R. 1. Smith (pp. 105- 

 107) . — Ol)servations were made on the laying habits of plum curculios, during which, 

 it was found that the largest number of eggs deposited by any single beetle was 436. 



Notes from New Mexico and Arizona, T. D. A. Cockerell (pp. 107-109). — Brief notes 

 on Parlatoria blanchardi, box-elder plant louse, Clisiocampa constricta, and a number 

 of beetles. 



,1 partial list of the Coccidseof Ohio, F. M. Webster and A. F. Burgess (pp. 109-113). — 

 The authors present a list of 71 species of Coccidae, with a statement of the food 

 I)lants upon which they were found. 



Observations upon the mosquito, Conchyliastes niusicus, H. A. Morgan (pp. 113-115). — 

 The female of this species is said to attack mammals furiously, and to cause swellings 

 on man as a result of its bites. The larvte are active at the surface of the water for 

 the first 24 hours, after which they may remain at the bottom for at least 47 minutes
