can Cordillera, the South American condor (Sarcorhamphus gryphm) and the 

 king vulture {Gypagus papa). This is accounted for through "the occurrence 

 of the parasite type on the common ancestor of all three of the related 

 (although generically distinct) host types, and its persistence practically un- 

 changed on each of the diverging descent products from this original ancestor- 

 host." 



Mallophaga from the birds of Laysan Island, V. L. Kellogg and J. H. 

 Paink {Ent. News, 21 {1910), No. 3, pp. 121,, 125, figs. 2).— Eleven species' are 

 recorded, of which one (Docophorus snyderi) is described as new to science. 



Locust destruction, 1909-10, A. Van Ryneveld (Agr. Jour. Cape Good Hope, 

 36 (1910), No. 2, pp. 158-166).— This is the report of the chief locust officer on 

 the work carried on in Cape Colony. The colony was again invaded by large 

 swarms of brown locusts in the early autumn of 1909. 



Biological notes on oriental Hemiptera, J. C. Kershaw and G. W. Kirkaldy 

 (Jour. Bombay Nat. Hist. Soc., 18 (1908), No. 3, pp. 596-598, pi. 1, fig. 1; 19

 sanguineus and Cwnocoris marginatu.s, Zicrona cwrulea, and Erthesina fiillo, 

 respectively. 



Further notes on the Aphididae collected in the vicinity of Stanford 

 University, W. M. Davidson (Jour. Econ. Ent., 3 (1910), No. J,, pp. 372-381, 

 figs. 2). — In this continuation of the study previously noted (E. S. R., 22, 

 p. 552), 2 species. Pemphigus ranunculi on stalks of Ranunculus calif ornicus, 

 and Rhopalosiphum arbuii common throughout the year on the under surface 

 of the leaves of Arbutus menzicsii, are described as new. 



Plant louse notes, family Aphidid^, C. P. Gillette (Jour. Econ. Ent., 3 

 (1910), No. 4, pp. 367-371, fig. 1). — In this continuation of the account previously 

 noted (E. S. R., 22, p. 552), IS species belonging to the subfamily Aphidinae are 

 noted. 



Scale insects in New Zealand, T. W. Kirk and A. H. Cockayne (New Zeal. 

 Dept. Agr. Ann. Rpt., 17 (1909), pp. 273-285, figs. 11,). — Summarized accounts 

 are given of the life history, habits, injury, and remedies for the more important 

 scale insects with which fruit gi-owers and others have to contend in New 

 Zealand. 



Insect pests of coconuts (Agr. News [Barbados], 9 (1910), No. 202, pp. 26, 

 27, figs. Ji). — The Bourbon scale (Aspidiotus destructor) , which occurs in enor- 

 mous numbers closely packed together on the under side of the leaf, is said to 

 be the most general in distribution and the most severe in its effect on the tree 

 of all the coconut pests. The coconut white fly (Aleyrodicus cocois) is also a 

 very severe pest. 



Some results from feeding eggs of Porthetria dispar to birds, C. W. Col- 

 lins (Jour. Econ. Ent., 3 (1910), No. J,, pp. 3.',3-3Jt6) .—Ot 35G gipsy moth eggs 

 fed to 3 English sparrows, 142 or 40 per cent were found intact in the excrement, 

 of which 7, or 2 per cent of the total number fed, hatched. The approximate 

 number found to be wholly or partly digested was 135, or 38 per cent. Experi- 

 ments made with a pigeon indicate that the vitality of gipsy moth eggs is totally 

 destroyed by the grinding process in the gizzard. 



A new fruit pest, C. French, Jr. (Jour. Dept. Agr. Victoria, 8 (1910), No. 1, 

 pp. 50-52, figs. 2) .—Heliothis armigera is reported to have caused much injury 

 to the apricot and other stone fruits in South Australia. 



On a method of combating the cochylis and eudemis moths, J. Capus and 

 J. Fettaud (Compt. Rend. Acad. Sci. [Paris], 150 (1910), No. 21, pp. 1351, 

 1352).— A brief report of experiments with Cochylis ambiguella and Eudemis
