later hiberatlnjjc material. When the crop is harvested all loose beads should 

 be collected and burned and the stubble burned over. As the early crop of seed 

 is practically destroyed by the midge and the second crop matures a very large 

 percentage of sound seed, it is thought possible that the practice of destroying 

 the tirst crop of seed and retaining the last crop will yield better results and at 

 the same time eliminate a large percentage of midges. When a small crop of 

 seed is desired for planting i)urposes it will be found practical to protect the 

 seed heads from the midge by bagging before the heads have broken through 

 the protecting sheath. 



Two new Cecidomyiidae, E. P. Felt (Etit. News, 21 {1910), No. 1, pp. 

 10-12). — Lasioptcra tripsaci, reared at Piano, Tex., from larvae occurring be- 

 tween the leaf blades of gama or sesame grass (Tripsacum dactyloides) , and 

 Cecidomijia opiinliw reared from Opuntia hanburyana received from the New 

 York Bontanical (lardens, are described as new to science. 



The carnivorous larvae of two species of mosquito, E. Gendre (Bid. t^oc. 

 Path. Exot., 2 (1909), No. 3. pp. 147-150; abs. in Bill. Inst. Pasteur, 7 (1909), 

 No. 12, p. 544)- — The larvre of Culex tigripes and of an undetermined species of 

 Megarhinus are reported to feed exclusively on the larvae of other mosquitoes. 

 Four or five Stegomyia larvie are consumed daily by C. tigripes and seven to 

 ten larvje by the Megarhinus species. 



Merniis larvae, parasitic in the larvae of Stegomyia fasciata, E. Gendre 

 (Tiiil. tior. Path. Exot., 2 (1909), No. 2, pp. 106-108; abs. in Bill. Inst. Pasteur, 

 7 (1909), No. 12, p. 544) • — In two localities at Labe, French Guiana, nematodes 

 (Merniis) were found in nearly all of the larvfe of iS. faseiata. 



Three new Trypetidae from the Pacific Islands, D. W. Coquillett (Ent. 

 News, 21 (1910). No. 1, pp. 12, h^). — Three species of Dacus from Polynesia, 

 two bred from guavas and one from oranges, are described as new to science. 



Viviparity in Phorocera serriventris and other flies, W. Wesche (Jour. 

 Quekett Micros. Club, 1909, pp. 451-458, pi. 1 ; abs. in Jour. Roy. Micros. Sac. 

 [London], 1910, No. 2, p. 165). — The author finds that by means of a microscope 

 it is possible to detect the viviparous condition of fiies, if the specimens are 

 properly cleaned and prepared, as the hard chitinous jaws of the larv.-e are not 

 dissolved by potash and are seen through the cleared plates. In addition to 

 this tachinid (P. serriventris) several other species have been found to be 

 vivifiarous, namely Oliviera lateralis, Plagia trepida, PJiora rupeornis, Myiobia 

 frnestrata, Hiphona genieulata, and Blepharidea vulgaris. 



Amara avida as a strawberry pest, J. B. Smith (Jour. Eeon. Ent., 3 (1910), 

 No. 1, pp. 97-101, pi. 1, Jig. I). — Because of cultural conditions which brought 

 about the removal of its normal insect food, this carabid beetle attacked the 

 berries and was the source of considerable injury to the strawberry crop in 

 Cumberland County, New .Jersey. 



Additions to the list of Kansas coleoptera for 1908, W. Knaus (Trans. 

 Kans. Acad. Sei., 22 (190H-9). pp. 351, 3o2).— Thirty-eight additional forms are 

 added to list of species found in Kansas. 



Bees, E. F. Phillips (U. S. Dept. Agr., Farmers' Bui. 397, pp. 4-'/. fiff-'^- 21).— 

 This brief summarized account aims to furnish such information as is needed 

 by persons engaged in keeping bees and supersedes Farmers' Bulletin 59, previ- 

 ously noted (E. S. R., 9, p. 770). 



The anatomy of the honey bee, R. E. Snodgrass (U. S. Dept. Agr., Bur. Ent. 

 Bui. 18, teeh. ser., pp. 162, figs. 57). — This detailed study of the anatomy includes 

 a discussion of the physiology of the honey bee. It is richly illustrated by 

 original drawings and a bibliograithy of the more important literature is 

 appended.
