Indies; Tetrasticlnis ovivonts, reared from eggs of Conchyloctenia parum- 

 maculata, at Entebbe, Uganda; and Sympiesis felti, reared from Agromyza 

 vielanopyga. 



On Ccelopisthia nematicida, a chalcid parasite of the large larch, sawfly, 

 Lygaeonematus erichsonii, C. G. Hewitt (CanacL Ent., ^3 (1911), No. 9, 

 pp. 297-303, figs. //). — In observations made on the development of this chal- 

 cidid parasite, it was found that in the September and October broods the 

 eggs, which are laid on the host larvre inside the cocoons, hatch in from 2 to 3 

 days. The larvae become full grown in from 10 to 12 days and the adults may 

 emerge about 23 days after the eggs are deposited. The parasite feeds ex- 

 ternally and hibernates as a mature larva inside the cocoon of the host. A 

 number of broods of the parasite occurs annually. 



The root borer and its parasite, H. W. Davey (Jour. Dcpt. Agr. Victoria, 

 9 (1911), No. 7, pp. 451-.'f55, fig. 1). — This paper includes a technical descrip- 

 tion, by H. L. Viereclj of this Department, of a new braconid parasite (Perilitus 

 leptopsi) of the apple root borer (Leptops Jiopei). In many districts of Vic- 

 toria this borer is one of the most formidable enemies of the fruit industry. 



The number of parasitic larvae contained in a beetle varies, an average of 25 

 having been found during the past season. 



On the Hymenoptera of the Georgetown Museum, British Guiana, P. 

 Cameron (Timehri, Brit. Gmana, 3. scr., 1 (1911), No. 3, pp. 306-330) .—This 

 second part of the paper previously noted (E. S. R., 26, p. 63), includes descrip- 

 tions of numerous new genera and species of Braconidfe and Tenthredinidse. 



The occurrence of Heemaphysalis punctata on cattle in the District of 

 Apenrade, P. Knuth (Berlin. Tierdrztl. Wchnschr., 27 (1911), No. 48, pp. 

 S65-86S, figs. 12). — The author records the occurrence of this tick in the Dis- 

 trict of Apenrade, which lies in the northern part of Schleswig-Holstein. This 

 is the first record of the occurrence of this important species in Germany, 

 Ixodes rieinus being the one which commonly transmits bovine piroplasmosis 

 in that country. 



The hothouse milliped as a new genus, O. F. Cook (Proc. U. 8. Nat. Mu^., 

 J/O (1911), pp. 625-631). — Fleshy fungi are said to be the only living plants 

 that are regularly eaten by millipeds. " Some of the native millipeds in the 

 vicinity of Washington, D. C, feed to a considerable extent upon the local 

 species of Amanita, Russula, and Lactarius. Damage is sometimes done to 

 other plants when millipeds gain access to wounded surfaces of roots or cut- 

 tings. Healing may be prevented or cuttings may be liept from rooting by 

 continual scraping of the exposed surfaces." 



The genus Oxidus is erected for Fontaria gracilis, a species widely distrib- 

 uted in the Tropics and in hothouses. 



The rubber slug (Mariaella dussumieri), E. E. Green (Circs, o/nd Agr. 

 Jour. Roy. Bot. Gard. Ceylon, 5 (1911), No. 22, pp. 337-3^3, pi. i).— This slug, 

 which occurs commonly in both cultivated and uncultivated land to an eleva- 

 tion of at least 2,000 ft. and probably higher, has attracted attention a& a 

 pest only in connection with the rubber industry. It first came into notice in 

 1905 through frequenting the recently tapped Hevea trees and imbibing the 

 latex as it oozed from the cuts. This habit results in an appreciable diminu- 

 tion of the scrap rubber that can be collected after tapping. 



About two new hop pests, B. Wahl (Wiener Landw. Ztg., 61 (1911), No. 

 36, p. 416). — Hydroecia micacea and an undetermined cecidomyiid are men- 

 tioned as enemies of the hop. 



Insect enemies and diseases of the tomato in Mexico, R. RamIeez and 

 J. R. INDA (Estac. Agr. Cent. [Mexico^ Bol. 56, 1911, pp. 46, pis. 16, figs. 11).—
