Two new g-enera of African Muscoidea, C. H. T. Townsend (Ann. and Mag. 

 Nat. Hist., S. ser., 11 {1916), No. 98, pp. 174-176).— The genera Congochrysosomu 

 and Ocypteroniiniu, together with the genotype of eacli, are described as new. 



The lantana seed fly, F. P. Jepson (Dept. Agr. Fiji Pamphlet SI (1916), p. 

 1; abs. in Rev. Appl. Ent., Ser. A, 4 (1916), No. 12, p. 529). — An agromyzid 

 introduced from Hawaii into Fiji is now so thoroughly established that it is 

 not possible to tind Lantana camara within several miles of Suva which is not 

 attacked. 



Plagiodera versicolora. — An imported poplar and willow pest, H. B. Weiss 

 and E. L. Dickkkson (Vunad. Ent., 49 (1917), No. 3, pp. 101,-109, pi. i).— This 

 imported chrysoinelid has been observed by the authors in New Jersey for the 

 past three years, appearing in greatest numbers at Irvington in a nursery on 

 pophir and at Souih Paterson on willow. Observations relating to its biology 

 are reported. 



Scientific annihilation of the tobacco beetle, R. G. Skekrett (Sci. Amer., 

 115 (1916), No. 15, pp. 319, 336, fig. 1; abs. in Rev. Appl. Ent., Her. A, 5 (1917), 

 No. 1, p. 3). — A description of an X-ray apparatus made practical use of in the 

 destruction of the cigarette beetle, an account of which by Runner has been 

 previously noted (E. S. R., 35, p. 554). 



Report of the South Carolina Boll Weevil Commission, W. M. Riggs (Clem- 

 son Agr. Col. S. C, Farmers' Reading Course Bui. 20 [1916], pp. 24, figs. 2; 

 U. 8. Seriate 64- Cong., 2. Sess., Doc. 701 (1917), pp. 20, figs. 2).— This is a re- 

 port of a commission which made a trip of inspection through the boll-weevil 

 infested territory. It includes a report of a meeting held at Brookhaven, Miss., 

 on October 7, 1916, a brief account of the life history of the boll weevil, a com- 

 parison of the conditions in Louisiana and South Carolina as related to the 

 boll-weevil problem in the latter State, effects of the boll weevil on cotton pro- 

 duction, oil mills, ginneries, etc., changes in agricultural methods due to the 

 boll weevil, and raising cotton under boll-weevil conditions. 



On some Curculionidae which live in bamboo stems, A oa Costa Lima 

 (Mem. Inst. Oswaldo Cruz, 8 (1916), No. 1, pp. 4^-43)- — This supplementary 

 paper (E. S. R., 33, p. 658) refers to Rhinastus pertusus in Chusquea gaudi- 

 chaudii, Desmosomus longipes, and Astyage punctulata n. sp., in Mcrostachys 

 clausseni mollior. 



The leaf weevil (Polydrusus impressifrons), P. J. Parrott and H. Glasgow 

 (New York State Sta. Tech. Bui. 56 (1916), pp. 3-24, pls. 8, figs. 6).— P. im- 

 pressifrons, an important European bud and leaf-eating beetle of which a pre- 

 liminary account has been noted (E. S. R., 36, p. 859), was first discovered in 

 western New York in 1906, where it occurs in several counties and in certain 

 localities has become very abundant, particularly in nurseries. It feeds on a 

 large variety of plants, particularly upon willows, poplars, and birches. It is a 

 source of injury through nibbling the developing buds of budded and grafted 

 stock and attacking the foliage and succulent tissues, as stems of newly-un- 

 folded leaves and stalks of terminal growth. The gouging of tender tissues is 

 not infrequently attended by severing of leaves and destruction of tips of 

 shoots. 



The adults, which are light metallic green in color, emerge from the ground 

 during May and early June and oviposition soon commences. The eggs are de- 

 posited under the loosened bark on dead stubs or about wounds due to prun- 

 ing or scars in the bark resulting from hail injury or attacks by insects, and 

 hatch in about 11 or 12 days. Upon hatching out the larvse enter the earth 

 and live on the roots of plants. Pupation occurs in the spring. 



A new braconid of the genus Diospilus, a description of which by A. B. 

 Gahan under the name Diospilus polydrusi is appended (pp. 23, 24), has been
