temperature ranges between 85 and 95° F., but when it falls below 70" they 

 become sluggish in their movements. Tiiere are said to be at least three gen- 

 erations at La Fayette, Ind., from the middle of May to October 1, apparently 

 six generations iu the latitude of Columbia, S. C, and at least eight genera- 

 tions during the year in the vicinity of Pasadena, Cal. The average length 

 of the life cycle is 44 days in the vicinity of Pasadena, 26.5 days from June to 

 August at Columbia, S. C, and 37.5 days during April and May at Tempe, Ariz. 

 Winter is passed in the pupal stage. 



A large number of parasitic Hymenoptera have been reared from this leaf 

 miner, namely, Cirrospilns flavoviridis, Cyrtogaster occidentalis, Diaulinus 

 websteri, Dlaulinopsis caUichroma, Polycystus foersteri, Dacmisa n. sp., 

 Vhrysocharus parksi, Opius dimidiatus, and O. aridus, which may be responsi- 

 ble for the almost complete disappearance of this leaf miner during mid- 

 summer in some localities. Preventive measures mentioned include fall plow- 

 ing or any thorough cultivation of grain fields to destroy the remaining stems 

 and leaves as well as volunteer grain, and the burning of dry grasses along 

 fence lines, etc., in late fall and early spring. 



A list of 14 references to literature is appended. 



Contribution to our knowledg'e of American Siphonaptera, K. Jordan and 

 N. C. RoTHscHir.D {Ectoparasites, 1 {1915), No. 1, pp. 45-60, figs. 11). — This in- 

 cludes descriptions of three new genera, four new species, and several new sub- 

 species of American fleas. 



On a Nosema (Nosema pulicis n. sp.) parasitic in the dog flea (Cteno- 

 cephalus felis), V. T. Korke {Indian Jour. Med. Research, 3 {1916), No. ^, pp. 

 725-730, pi. 1). — In dissections made of dog fleas at the Central Research In- 

 stitute at Kasauli, India, the author has found frequent infections of the diges- 

 tive tract by a new species of Nosema, which he has named N. pulicis. Fleas 

 taken from a dog, about one in every six of which were infected, were placed 

 in a breeding cage and fed daily on wild black rats. This resulted in the spread 

 of the parasite so that practically every other larva was infected in about three 

 weeks' time. 



A catalogue of Philippine Coleoptera, W. Schultze {Philippine Jour. ScL, 

 Sect. D, 11 {1916), Nos. 1, pp. 94; 2, pp. 95-194).— A classified catalogue of the 

 Philippine beetles.

 pp. 185, 186; Ann. Rpt. Ind. Bd. Forestry, 15 {1915), pp. 166-168).— A beetle 

 {Chalepus dorsaUs) is reported to have worked extensively in the leaves of 

 locust in four counties of southern Indiana during June and July, 1914. 



Biology of Cerambyx heros, A. Barbey {Bui. Soc. Vaud. Sci. Nat., 5. ser., 50

 out Europe, but occurring much more frequently in the central and southern 

 parts of the Continent, is the source of considerable injury to the oak. 



The cane-borer beetle in Hawaii and its control by natural enemies, F. 

 MuiR and O. H. Swezey {Haivaiian Sugar Planters' Sta., Ent. Bui. 13 {1916), 

 pp. 102, pis. 3, figs. 31). — The first part of this work deals with the history of 

 the search for parasites and introduction of the tachinid Ceromasia sphcnophori 

 from British New Guinea into Hawaii, successfully accomplished in August, 

 1910, an account of which by Swezey has been previously noted from another 

 source (E. S. R., 33, p. 256). Then follows an account of the life history, 

 habits, distribution, natural enemies, etc., of the cane-borer beetle {RJiabdoc- 

 nemis obscura), much of the data relating to which have been previously pub- 

 lished. Artificial means of control and natural enemies in Hawaii, next taken
