ENTOMOLOGY. 167 



Entomology of the oak, A. T. Gillanders (Trans. Manchester Micros. Soc, 1897, 

 pp. 78-SS; abs. in Jour. Boy. Micros. Soc. [London], 1S98, No. 3, p. 74). 



A preliminary review of the North American Delphacidae, E. P. Van Dczke 

 {Buffalo Soc Nat. Sci. Bui., 5, Xo. 5, pp. 225-261). — A taxononiic paper mentioning 

 old and describing new species. 



Studies on insect larvae. I, On the knowledge of Phalacrocera replicata, S. 

 Bexgtssox (Lands Universitats Arsskr., 33 (1897), pp. 118, pis. 4; abs. in Zool. Centbl., 

 5 (1S0S), Xo. S. pp. 268-272). — The entire development of this water larva runs 

 through the course of a year. The egg state lasts from 8 to 12 days, the pupal period 

 7 to 8. There have been 8 moltings determined with certainty and very probably 

 there are 9, if not 10. The old skin always hursts longitudinally along the hack. 

 Though the larva has a true head, it forms a link between the well-marked head of 

 the encephalic dipteran larvae with the "jaw cap" of Tipulid and other dipteran 

 larva-. Three thoracic and nine abdominal segments are to be distinguished. 



Hymenoptera, Neuroptera, Psendoneuroptera, Orthoptera, and Rhingoca of 

 Italy. A. Gkiffixi (Imenotteri, Xeurotteri, I'seudoneurotleri, Orthotteri, e Rincoti llal- 

 iani. Milan: U. Hoepli, 1897, pp. XV-\-677, figs. 223). — In treating of each genus an 

 example is figured and treated morphobiologically. For a preliminary study of 

 insects the volumes are very useful, although they can not give a complete scientific 

 conception of Italian fauna, and since the authorities for the species are not mentioned 

 the latter can not he placed with certainty. 



On two Lepidoptera injurious to sugar cane introduced into the Masca- 

 reignes Islands, E. Bordage (Compt. Bend. Acad. Sri. Paris, 12-7 (1897), Xo. 25, pp. 

 1109-1112). — The history of the introduction and synonymy of LHatrcea striatalis and 

 Sesatnia nonagrioides. 



Considerations on the study of melliferous plants, A. Sonsiedsky (Ber. Inter- 

 nal. Apicult., 20 (1898), Xo. 4. pp. <:S-71). — The meagerness of any popular literature 

 on the subject of melliferous plants is noted, yet the subject is well worth study. 

 A well-known Russian apiculturist. Zonbareff, in a work on apiculture states that 

 one can not give any one plant absolute preference, for the same plant on different 

 soil and under different conditions of climate varies in the quantity and quality of 

 nectar yielded. Plants considered to be of secondary value in one country or local- 

 ity in others may take first rank. Melissa officinalis is indigenous to a moist climate 

 and loses its melliferous qualities in a dry one. 



Bee keeping and its regulation in the Middle Ages and in recent times, 

 M. "Wagner (Inaug, Diss., Munich, 1897, pp. 89. pi. 1, maps 3). — This deals with bee 

 keeping in its historical and legal aspects, going back to the time of Charlemagne. 



Something new relative to the development of gadfly larvae of cattle, 

 Schxeidemuhl (Centbl. Bakt. u. Par., 1. AM., 22 (1S9S), Xo. 24-25, pp. 752-760).— 

 Besides making historical mention of several (Estrida-, the pathological significance 

 of (Bstrix oris is noted and more at length the life history of Hijpoderma bovis. Con- 

 trary to the belief hitherto current, the larvae of the latter insect passes the greater 

 portion of its larval existence inside the animal. The eggs enter the alimentary 

 canal partly with the fodder and partly from licking the skin. 



Notes on the season of 1896, J. A. Moffat (Bpt. Ontario Ent. Soc, 1$9<:, pp. 

 76—79, Jigs. '.'). — The climatic conditions in the southern portion of Ontario are noted 

 as having been very diverse within short distances, but the Colorado beetle and the 

 imported cabbage butterfly seem to flourish under all conditions. Hadena arctica, 

 winch were very abundant in 1895, were exceptionally rare this year. The army 

 worm (Leucania nuipuncta) was very destructive near Hamilton. Ontario. A Harpa- 

 lus was found preying upon it. The lime-tree winter moth (llybernia lilii.ria) was 

 very abundant around London, Ontario, in the early part of October. Other insects 

 noted are Papilio marcellus. P. philenor, P. eresphontes, Erebus odora, the Carolina 

 sphinx (Macrosila Carolina . Cisthene nnifascia, Aspila virescens, and Hyphaniria cunea, 

 the last being very prevalent.
