 with the rules and regulations of the commissioner of agriculture relating 

 thereto, E. R. Kone (Texas Dcpt. Ayr. Virc. 1, n. scr., pp. 11). — Au excerpt of

 pp. L'lS-l'iG, pis. 9). — Of the 15 forms of galls described in the first paper, 10 

 are formed by species of Eriophyes and 5 by species of Cecidomyia. Descrip- 

 tions are presented in tbe second paper of galls formed by 5 species of 

 Eriophyes, of 7 formed by species of Cecidomyia, and 3 by species of Cyuips.

 m are peculiar to Cuba and 25 to tropical and subtropical America, 24 are 

 Autillean in distribution, 23 occur in South America and the Antilles. 14 occur 

 in North America and Cuba only, and H) are circunitropiral. 



Some new Thysanoptera from southern California, I, D. L. Crawford 

 (Pomona Jour. Ent., 1 (1909). Xo. -'/, pp. 100-108, figs. .',).— A genus (An- 

 kothrips), 3 species, and 2 varieties are described as new to science. 



Notes on California Thysanoptera, I (Pomona Jour. Ent., 1 (1909), No. ^, 

 pp. 120, 121). — Notes are given on the occurrence of Euthrips tritici, Tlirips 

 tabaci, T. madronii, Heliothrips fasciatiis, and Lcptothrips aspersiis.

 Join: Ent.. 1 (1909), A o. .',, pp. 109-119. figs. J,). — The genus Rhaptothrips, 3 

 species and 1 variety from near Guadalajara, Mexico, and 1 species from 

 Managua, Nicaragua, are described as new to science. 



The apple leaf -hopper, R. L. Webster (Iowa Sta. Bui. Ill, pp. 5-32, figs, 

 l.'f). — During the season of 1909 apple leaf-hopiiers were particularly abund- 

 ant in Iowa nurseries, their attack resulting in the stunting of a large number 

 of trees. 



The young hoppers are especially conmion on nursery stock four times dur- 

 ing the season, viz, the latter part of May. June, July, and August, when the 

 different generations appear. The work of the insect becomes evident through 

 a peculiar curling of the growing tops of nursery stock, particularly of the 

 apple stock during the month of June. " The result of au attack of the leaf- 

 hoppers is that the growth of the new wood is shortened, the leaves grow close 

 together on the branches, and the whole tree fails to attain the size it should 

 in a season's growth. Consequently many niu'sery trees do not become the 

 proper size in three years and fre(pieutly they must be left for another year 

 to complete their growth." 



The winter is passed both in the egg and in the adult stages. So far as 

 known the winter eggs are placed only in the bark of apple trees, while dur- 

 ing the summer they are deposited in a large number of food plants in the 

 petiole or in the larger veins of the leaves. Although the period required for 

 the incubation of the egg has not been determined, it is shown to be at least 

 days or longer in August. In 1909 the first young were observed on May 13. 

 Insectary records have sliown considerable variance in the time lengths of 

 the 5 nymphal stages, technical descriptions of which are presented. About 

 a mouth is required for the completion of the life cycle from egg to adult. In
