56 EXPERIMENT STATION RECORD. 



Endaphis in the Americas, E. P. Felt {Ent. News, 22 {1911), No. 3, pp. 

 128, 129).-— Two species of the European cecidomyiid genus Endaphis, namely, 

 E. aMominalis, reared in Peru from cotton leaves badly infested with galls 

 containing mites, and E. amcricana, reared from galls of Eriophyes fraxiniflora 

 on Fraxinus velutma at Prescott, Ariz., are described as new. 



Dengue and Steg'omyia, J. Legendre (Bui. Soc. Path. Exot., 4 {1911), No. 1, 

 pp. 26-30 ) .—During the course of an epidemic of dengue fever which prevailed 

 for many months at Hanoi, French Indo-China, during which the major part 

 of the population, both native and European, suffered, the author made numer- 

 ous observations and was led to conclude that the Stegomyia mosquito was the 

 active agent in its transmission. 



Mosquitoes and malaria, H. Waite {Bionietrika, 7 {1910), No. Jf, pp. 421- 

 436, dgms. 5).— A study of the relation between the number of mosquitoes in 

 a locality and the malaria rate. 



A preliminary report on the investigation into the breeding places of the 

 sand fly in Malta, P. J. Marett {Jour. Roy. Army Med. Corps, 15 {1910), No. 

 S, pp. 286-291). — Notes on the life history and habits of Phlehotomus papa- 

 tasii. 



Myiasis dermatosa due to the ox warble flies, R. T. Miller {Jour. Amer. 

 Med. Assoc., 55 {1910), No. 23, pp. 1918, 1979).— The author reports a case in 

 which the larva of IJypoderma lineata in the second stage was taken from the 

 knee of a human patient from Roanoke, Ya. 



The Mexican orange maggott (Anastrepha [Trypeta] ludens), D. L. 

 Crawford {Pomona Jour. Ent, 2 {1910), No. J/, pp. 321-332, figs. /,).— The 

 author reports having found this pest in 1910 at several points in the State of 

 Chiapas, Mexico, and that it is also present in the fruit districts of Cordova, 

 Oaxaca, Jalapa, and Colima. A parasite taken by him in the act of depositing 

 eggs in the maggots in oranges, mangoes, and guavas has been identified as 

 Diachasma sp. 



The author considers the great and immediate danger from the maggot to 

 be to the citrus groves of Texas, New Mexico, and Arizona. 



On the raising of sterile flies, E. Wollman {Ann. Inst. Pasteur, 24 {1911), 

 No. 1, pp. 79-88, figs. 2). — A contribution to the knowledge of the role of 

 microbes in digestive tracts. CalHplwra vomitoria and Lucilia ccesar were 

 used in the studies here reported. 



On the biology and pcecilogonic viviparity of the cattle fly (Musca cor- 

 vina) in tropical Africa, E. Rotjbaud {Compt. Rend. Acad. Sci. [Paris], 152 

 {1911), No. 3, pp. 158-160). — Observations made in Dahomey are here reported. 

 Studies of the stomoxydes of Dahomey, B. Roubaud {Bui. Soc. Path. Exot., 

 4 {1911), No. 2, pp. 122-132). — The stomoxydes are repi-esented in Dahomey by 

 2 genera, Stomoxys and Lyperosia. Systematic and biological notes are pre- 

 sented on 8 species of Stomoxys that occur in the colony. A single and little- 

 known species, longipalpis, is the only representative of the genus Lyperosia. 



In September the author received from Abomey a collection of dead flies 

 {S. calcitrans) that were affixed in large numbers to potato leaves and also 

 reported by the sender to be found upon the bodies of asses. Examination 

 showed that they had been destroyed by an entomophthorous fungus. In ex- 

 periments conducted it was discovered that through the ingestion of spores, the 

 house fly could also be infected. The complete development of the mycelium 

 that causes the death of the fly takes place in 24 hours, and the maximum 

 period required by the fungus to kill the fly does not exceed 4 days. 



On West African Trypetidae (fruit flies), W. M. Graham {Bui. Ent. Re- 

 search, 1 {1910), No. 3, pp. 161-171, pis. 3, fig. i).— Two species of fruit flies 

 of the genus Ceratitis and o of the genus Dacus are described as new.
