 sulphur wash, the first containing 25 lbs. lime, 20 lbs. sulphur, and 1-j lbs. >al soda 



per barrel of water, and the second < tabling :;<> lbs. lime, 15 lbs. sulphur, and 5 



lhs. caustic soda per barrel of water. After careful application of these two forms of 

 wash it was found thai excellent results were obtained with both and that little 

 difference could be Been in their effectiveness. Attention is also called to the recenl 

 progress in entomological study including the importation of parasitic and predace- 

 ous enemies, the development of effective insecticides, study of malaria, etc. 



The distribution of insects in the Great Basin was discussed by H. F. Wickham, 

 and insects injurious to orchard crops in l'.'<)4 were considered by .). Fletcher. 

 The latter called attention to the comparative scarcity of the pea weevil, the 

 attacks of asparagus hectics, cahbage aphis, cutworms, beet-leaf miner, cabbage 

 worms carrot fly, San Jose* scale, New York plum scale, squash bug, and insectE 

 house plants. The same author briefly reviewed some of the entomological work of 

 .004.

Leaf hoppers and their natural enemies, R. C. L. Perkins I Hawaiian Sugar

 205-288, pis. ./'; 8, />/>■ 239-267, pis. .?). — Earwigs occasionally do damage to garden 

 plants, Imps, etc. Some of these are also insectivorous. Among the eighl species 

 of earwigs in Hawaii five have been observed in cane fields and two seem to he of 

 Borne importance in destroying leaf hoppers. These species are Chelisoches ///"/''"and 

 Anisolabis annulipes. These are described in all their stages. Notes are also given 

 on Chrysopa microphya, Baccha siphaniicida, and B. monobia. The last two species 

 belong to the family Syrphida- and are described as new. 



The family Mymaridse contains a number of parasitic insects which live upon vari- 

 ous orders of insects. One of the most important species as a parasite of leal hoppers 

 is Paranagrus optabilis. Various other new species of this family are described, and 

 not.- and descriptions are also presented of new species of Proctotrupoidea. 



Mention is made of a number of enemies of leaf hoppers found among Orthopnea. 

 Coleoptera, and Ilemiptera. The most important predaeeous insect discussed is the 

 grasshopper Xiphidium varipenne, which is described as a new species. This species 

 is largely insectivorous and feeds during all its stages on various insects. The young 

 grasshoppers were observed catching and eating nymphs of the leaf hoppers. An 

 examination of the stomach contents of these grasshoppers showed that i'I percent 

 of them contained insect remains. Notes are also given on A', latifrons, Callmeda 

 testudinaria, Coccinella repavda, Veraniafrenata, and a number of Ilemiptera. 



Notes are given on three other families of parasites, Fncyrtida-, Fulophida-, and 

 Trichogrammidse. Particular attention is given to the classification of the parasites 

 of these families with descriptions of new genera and species. A brief bibliography 

 i> added and a table given of the species discussed. 



Combating- scale insects, Tbabut (Bnl. Ayr. Algirie >t Tunisie, li '■!!">■'>), Xo.

 orange trees. While good results may be obtained by the use of various form- of 



petroleum emulsions, these remedies are considered difficult to prepare and apply. 



Lime-sulphur-salt wash is recommended as a reliable insecticide for scale insects on
