Fung-US diseases of scale insects and white fiy, P. H. Kolfs and H. S. Faw- 

 CETT. revised by P. H. Rolfs (Florida Sta. Bui. 119, pp. 71-82, figs. 19). — A 

 revised edition of Bulletin 94, previously noted (E. S. R., 20, p. 556). 



A study of caprification in Ficus nota, C. F. Baker {Philippine Jour. Sc-i., 

 Sect. D, 8 (1913), No. 2, pp. 63-83, figs. /#).— Following a general discussion of 

 the subject, the author describes several new species of fig insects occurring at 

 Los Bancs, namely, Bl<istophaga nota, the normal inhabitant of the gall 

 flowers and active caprifier of F. nota; Agaonella larvalis n. g. and n. sp., 

 common in F. nota and probably a guest in its relation to the Blastophaga ; 

 Sycophaga nota, not at all common in gall figs of F. nota and apparently a 

 guest; Sycoryctes philippinensis, found in great numbers in November in gall 

 figs of F. nota, and thought by the author to be a parasite in its relation to 

 the Blastophaga ; Philotrypcsis similis, common in F. nota; P. ashincadii, fre- 

 quent in gall figs and probably parasitic on Blastophaga ; and P. collaris, foimd 

 occasionally in gall figs and probably parasitic on Blastophaga. 



Synoptic lists of the male and female fig insects found in F. nota are 

 api>ended. 



A systematic outline of the Reduviidse of North America, S. B. Feackeb 

 (Proc. Iowa Acad. »S'ci, 19 (1912), pp. 217-252) .—This paper consists largely of 

 keys to the genera and species of the "assassin bugs" of North America. A 

 bibliography of the more important literature and an index to the genera and 

 species are included. 



The British species of the genus Macrosiphum, I and II, F. V. Theobald 

 iJ<jt(r. Econ. Biol., 8 (1913), Nos. 2, pp. 47-94, fiU^^. 30; 3, pp. 113-154, fius. 29).— 

 In ihe first paper the author deals with 25 species of aphids of the genus 

 Macrosiphuin which occur in Great Britain, of which 4 are described as new to 

 science. The second paper deals v.'ith 35 additional species, of which 8 are 

 described as new to science. 



Report of the entomolog-ists, W. E. Rumsey and L. M. Peairs (West Vir- 

 ginia Sta. Rpt. 1912, pp. 20-24)' — In experiments conducted with a view to 

 perfecting a spray which will destroy the eggs of the apple aphis when applied 

 while the trees are dormant, a block of 31 2-year-old apple trees on the station 

 grounds was made use of. Applications of lime-sulphur 1 : 8, soluble oil 1 : 10. 

 Kiloscale 1 : 10, blackleaf 40 1 : 20, and nicotin sulphate 1 : 65 and weaker 

 strengths of all these were made on March 27. The results seem to indicate that 

 commercial lime-sulphur at the strength of from 1 : 8 to 1 : 10 if thoroughly ap- 

 plied will destroy the winter eggs of the aphis. In tests made of summer sprays, 

 including soluble oil 1 : 36 and 1 : 45. lime-sulphur 1 : 45, and nicotin sulphate 

 1 : 900 applied May 20, and of several combination si^rays applied June 7. the 

 nicotin sulphate gave decidedly the best results, killing the aphis without dam- 

 aging the trees. 



The so-called aerostatic hairs of certain lepidopterous larvas, W. A. Riley 

 (Science, n. ser., 37 (1913), No. 958, pp. 715, TiG).— Attention is called to the 

 fact that it appears to have been very clearly established that the so-called 

 aerophores do not aid in rendering the larvte more buoyant, but that they contain 

 a poisonous fluid which serves to protect the caterpillars against insectivorous 

 birds. 



On the parthenogenesis and oviposition of the potato tuber moth 

 (Phthorimsea operculella), F. Picard (Gompt. Rend. Acad. Sci. [Paris], 156 

 (1913), No. 14. pp. 1097-1099) .—When placed with potato tubers the moths 

 wero found to oviposit in from 1 to 2 days following mating, from 40 to 80 eggs 

 being deposited within 1 to 3 days. The moth is said to oviposit on a large num- 

 ber of solanaceous plants, on rugous surfaces and in the depressions about the
