New chalcidoid Hymenoptera, A. A. Giraxjlt (Ann. Ent. Soc. Amer.. 8 

 (1915), No. 3, pp. 279-284). — One genus and 8 species are here described as new 

 to science, among which is Aphi(lencyi'tn,s aspidioti, reared from Aspidiotus per- 

 niciosus at Lansing, INIich. Coccidencyrtus ensifer is recorded as reared from 

 Aspidiotus jnylans-regiw at Musl^egon, Mich. 



Chalcidoidea bred from Giossina morsitans in Northern Rhodesia, J. 

 Wateeston (Bui. Ent. Research, 6 (1915), No. 1, pp. 69-82, figs. 5).— Three 

 species representing as many widely separated groups in the superfamily Chal- 

 cidoidea are considered, two of which are described as new to science. 



Two new Mymaridse from the eastern United States, A. A. Girault (Ent. 

 News, 21 (1916), No. 2. pp. 69, 70). 



Notes on some sawfly larvae belonging to the genus Dimorphopteryx, 

 W. MiDDLETON (Proc. U. S. Nat. Mus., 48 (1915), pp. 497-501. pi. 1, figs. 4) .— 

 These notes relate to Dimorphopteryx castanece on chestnut at Falls Church 

 and Wiehle, Va., and Blythedale, Md. ; D. autumnaUs on red oak at Falls Church 

 and Wiehle, Va. ; D. quercivora on red oak at Tomahawk Lake, Wis. ; and D. 

 errans on birch and linden. 



Ticks: A monograph of the Ixodoidea. — Bibliography of the Lzodoidea, II, 

 G. H. F. NuTTALL ami L. E. Robinson (Cambridge: University Press, 1915, pp. 

 W+S2). — This addition to the bibliography previously noted (E. S. R., 25, 

 p. 858) lists 462 papers, a large proportion of which have appeared since the 

 publication of the first part. 



Ticks: A monograph of the Ixodoidea, III, The genus Hsemaphysalis, 

 G. H. F. NuTTALL and C. ^Vabbueton (Cambridge: University Press, 1915, pp. 

 XIII-\-349-550, pis. 9, figs. 143). — The authors recognize 50 species and varieties, 

 including the three specie3 H. spinulosa, H. obtusa, and H. numidiana, the 

 validity of which is somewhat doubtful. The synonymy and references relat- 

 ing to publications which deal with the genus Hsemaphysalis and the generic 

 characterization are followed by keys for the determination of the species of 

 the genus, including males, females, nymphs, and larvae, so far as known. Spe- 

 cific descriptions of valid species of the genus and of their varieties, which take 

 up the greater part of the work (pp. 362-506), are followed by an account of 

 the geographical distribution and hosts of the genus ; a list of condemned and 

 doubtful species of Ha^maphysalis, including their synonymy and literature ; 

 notes on the biology of Hiemaphysalis (pp. 518-547), by G. H. F. Nuttall ; and 

 an index to valid species of the genus, together with a list of collections in 

 which the types are to be found. 



The cassava mite, S. Leefmans (Dept. Landb., Nijv. en Handel [Dutch East 

 Indies], Meded. Lab. Plantenziekten, No. 14 (1915), pp. 85, pis. 8; abs. in Rev. 

 Appl. Ent., Ser. A, 8 (1915), No. 11, p. 632). — The red spider which injures 

 cassava in Java is Tetranychus bimaculatus or closely related to it. Stripping 

 and burning the leaves is the only remedial measure thus far found to give 

 satisfactory results. 



The leaf blister mite of pear and apple, A. L. Quaintance (U. S. Dept. 

 Agr., Farmers' Bui. 722 (1916), pp. 6, figs. 4). — A reprint of Bureau of Ento- 

 mology Circular 154, previously noted (E. S. R., 27. p. 565). 



On a widely distributed gamasid mite (Leiognathus morsitans n. sp.), 

 parasitic on the domestic fowl, S. Hiest (Bui. Ent. Research, 6 (1915), No. 1, 

 pp. 55-58. figs. 3). — L. morsitans, here described as new, is said to have a very 

 wide distribution in Africa and also to be found in Mauritius, China, India, and 

 South America. It appears to be the common bloodsucking gamasid mite of 

 poultry in these countries.
