656 EXPERIMEB-T STATION RECORD. [Vol. 36 



In bins, the progress of infestation can be checked by holding the potatoes In 

 cold storage. The temperature should be about 37 to 40° F. This should be 

 adopted only as a temporary method in keeping potatoes from deteriorating in 

 value while they are being held for a rise in price." 



A map showing the localities in which the potato moth is established on 

 potato, localities in which it is established on other plants, and localities 

 where it has been introduced but is not established is attached. A bibliography 

 of 96 titles is included. 



The rhododendron tingid (Stephanitis rhododendri) in Surrey, E. E. Gkeen 

 {Ent. Mo. Mag., S. ser., 2 (1916), No. 21, pp. 207, 208).— The author records the 

 occurrence of this pest at Camberley. 



A note by G. C Champion appended calls attention to the fact that Lepto- 

 byrsa explanata, described by Heidemann in 1908 as occurring abundantly on 

 mountain laurel (Kalmia latifolia) and injuring the foliage of Rhododendron 

 maximum along the Atlantic coast of the United States (E. S. R., 21, p. 451), 

 is certainly the same species. An account of the life history of L. explanata 

 by Crosby and Hadley has been previously noted (E. S. R., 34, p. 451). 



Observations of the biology of Recurvaria nanella, A. Mignone {Atti R. 

 Accad. Lincei, Rend. CI. Sci. Fis., Mat. e Nat., 5. ser., 25 (1916), I, No. S, pp. 

 188-195). — This is a preliminary report of studies of the lesser bud moth in 

 Italy. Studies of this pest by Houghton in England (E. S. R., 15, p. 787) and 

 by Scott and Paine in the United States (E. S. R., 31, pp. 252, 755) have been 

 previously noted. 



Evolution of the color pattern in the microlepidopterous genus Litho- 

 colletis, Annette F. Braun (Jour. Acad. Nat. Sci. Phila., 2. ser., 16 (1915), pp. 

 105-166, pis. 2, figs. 26). — Among the species listed, in which the development 

 of the pattern has been traced from the first appearance of color to the adult 

 markings, TAthocolletis cratoegella is of economic importance. 



Neuropteroid insects of the Philippine Islands, N. Banks (Philippine Jour. 

 Set., Sect. D, 11 (1916), No. 5, pp. 195-211, pis. 2). 



The control of the house fly, R. Blanchard (Ligue Sanit. Franc. Bui. 5 

 (1915), pp. 63, figs. 27; abs. in Jour. Roy. Army Med. Corps, 26 (1916), No. 2, 

 pp. 248-254, figs. S). — A general discussion of the subject, of the more important 

 species occurring in the house, their manner of reproduction, diseases trans- 

 mitted, and control measures. A discussion by H. G. Richter of the manner of 

 arranging manure heaps in order to destroy the fly larvje contained therein is 

 appended (pp. 59-62). 



Prevention of fly breeding in horse maxiure, S. M. Copeman (Lancet [Lon- 

 don], 1916. I, No. 24, pp. 1182-1184, figs. 2).— The author reports experiments 

 with the " close-packing " method of controlling the house fly in horse manure 

 about military camps. 



It was found that the temperature developed during fermentation largely 

 depended on the manner in which the manure was stacked dui'ing the building 

 of the heap. In temperature experiments by F. M. Howlett maggots were 

 found to be killed quickly by either dry or wet heat at any temperature above 

 114.8° F., and he considers it improbable that they could live long at any tem- 

 perature above 106°. Records kept of temperatures in piles of manure showed 

 that at no great depth from the surface the heat was too great to permit the 

 existence of larvae. On the top of the piles the larvae were living only in the 

 surface layers, and the excessive heat due to fermentation becomes practically 

 a larvicide. 



Some experiments on the house fly in relation to the farm manure heap, 

 H. Eltrtnqham (Jour. Agr. Sci. [England], 7 (1916), No. 4, PP- 44S-457, figs. 

 S). — This is a report of a series of experiments conducted with a view to test-
