ladybird beetles, and with the Bureau of Entomology of the same Department 

 through its station at Forest Grove, Oreg. 



Five new species of ptinid beetles, W. S. Fisher (Froc. U. S. Nat. Mus., 55 

 (1919), pp. 295-299). — The species here considered are Pitnus hucsanus n. sp., 

 collected on Ichthyomethia piscipula at Key West, Fla. ; Oligoinerus arbuti 

 n. sp., on dead manzanita (Arbtitus sp.) at Placerville, Cal. ; Etnobius coni- 

 cola n. sp., reared from cones of Cupressus macrocarpa and from larvae feeding 

 on scales and tissues of green and dry cones of C. macrocarpa at Pacific Grove 

 and Point Lobos, Cal. ; E. calif amicus n. sp., reared from bark and outer wood 

 of branches of recently killed Pinus jeffrcyi in Ventura County, Cal. ; and 

 E. champlaini n. sp., collected on dead limbs of P. flexilis in Waldo Canyon, 

 Colo.

 (1919), pp. 78, figs. ^S). — A popular account. 



Elements of beekeeping', H. R. Niswonger (Univ. Ky., Col. Agr. Ext. Div. 

 Circ. 69 (1919), pp. 22, figs. 8). — A popular account. 



Unheated egg-yolk media, G. F .White (Science, n. ser., ^9 (1919), No. 1267, 

 p. 362.) — The author has for several j-ears made use of unheated egg-yolk luedia 

 and found them specially valuable in studying Bacillus larixe, which offers con- 

 siderable difficulty in its cultivation. The technique employed in its preparation 

 is described. 



The carpenter ant as a destroyer of sound wood, S. A. Graham (Rpt. State 

 Ent. Minn., 17 (1918), pp. 32-JtO, figs. 8). — "Large black ants commonly known 

 as carpenter ants [Componotus pennsylvanicus] are doing considerable damage 

 to standing white cedar in Minnesota, at least 20 per cent of the trees cut 

 showing ant injury on the stump. The colonies are started in a wound, knot 

 hole, or decayed spot, usually near the butt of the tree. The ants hollow out 

 a nest in the heart of the tree, sometimes leaving only a thin shell of wood 

 around it, thus seriously weakening the tree at that point. From this nest the 

 ants cut openings to the outside, called windows, and to locate a nest it is only 

 necessary to look for the windows. 



" Much unavoidable loss is occasioned by ant injury, but there is also an 

 immense amount of loss through careless cutting of poles. Culling heavily for 

 ant injury has meant leaving in the woods anything that looks suspiciously 

 like a cull. The grading rules regarding ant injury should be made more 

 lenient so as to encourage more careful trimming of ant-infested poles." 



Three new species of Braconidae, C. F. W. Muesebeck (Canad. Ent., 51 

 (1919), No. 5, pp. 113-116). — Among the species here described as new is Apan- 

 teles phigalia', which parasitizes Phigalia titea at Melrose Highlands, Mass. 



New reared parasitic Hymenoptera, with some notes on synonymy, A. B. 

 Gahan (Proc. U. S. Nat. Mus., 55 (1919) pp. 113-128, figs. 2).— This paper con- 

 tains descriptions of 2 genera and 12 species of Ichneiunonoidea and Chalci- 

 doidea, including Phaeogenes (Centcterus) ineptifrons n. sp., reared from the 

 oriental peach moth (Laspeyresia molesta) at Washington, D. C. ; Dacnusa 

 iridicola n. sp., reared from Agromyza laterella at INIiddleburg, Pa.; Trioxys 

 cuprcssicola n. sp., from Cerosipha n. sp., at Riverside, Cal.; Chelonus (Chelo- 

 nella) proteus n. sp., and Apantcles stagmatopliora; n. sp., both from Stagmato- 

 phora gleditschiwrlla at Williamsport, Md. ; Bassus imniaculatus n. sp., reared 

 in connection with and possibly parasitic on Phthorimwa .^triatella at Baton 

 Rouge, La. ; B. usitatus n. sp., reared in cages with the cranberry fruit worm 

 and probably parasitic on it at East Wareham, Mass. ; Orgihis dioryctrice n. sp., 

 from Dioryctria xanthaenobares on Pinus attemiata, Patricks Creek, Cal. ; 

 Pseuderiinerus mayetioke u. g. and n. sp., from the Hessian lly at Altamout, Cal. ;
