758 EXPERIMENT STATION RECORD. [Vol.41 



Contribution to the study of the Brazilian Trypaneidee or fruit flies, A. 

 LuTZ and A. da Costa Lima (ilent. Inst. Osicaldo Cruz, 10 (JOIS), No. J, pp. 

 5-16, pin. 2; Trans., pp. 1, 2). — This account is based upon the specimens found 

 in collections at the Institute of Manguinhos and of the Museum of Natural 

 History in Sao Paulo. Anastrepha fraterculus, a very variable species, an 

 account of which by liust has been previously noted (E. S. li., 40, p. 757), is 

 the most important form. A list is given of the species of the genus Apyrgota, 

 subfamily Pyrgotinse, and a description of the new species A. personata which 

 might be mistaken for a Trypeta. A catalogue of the genus Anastrepha with 

 synonyms, literature, and a bibliography follows. 



Notes on Pelenomus sulcicollis, R. Matheson (Cannd. Ent., 51 (1919), No. 

 8-9, pp. 199-201, pi. 1, fly. 1). — The weevil here considered is said to have de- 

 stroyed a small patch of fringed loosestrife (Stcironema ciliatuin) growing 

 on the bank of a stream at Ithaca, N. Y. 



The two-colored coconut leaf beetle (Bronthispa froggatti), S. Leefmans 

 {Dept. Landb., Nijv. en Handel [Dutch East Indies], Meded. Lab. Plantenziek- 

 ten, No. 35 (1919), pp. 1-14, P'«- 3). — The beetle here considered, which has not 

 previously been recorded by Dutch entomologists, is thought to be the species 

 which has caused serious loss in New Britain and the Solomon Islands, On 

 the west coast of Sumatra and in west Java only plants up to four years of 

 age are damaged by it. It is the author's opinion that the injury caused by 

 the adults and larvje is considerably increased by a fungus (Pcstalozzia pal- 

 marum) which penetrates the leaf tissue through the wounds caused by this 

 insect. 



The larvae hatch out after a period of 7 to 10 days, the pupal stage lasts 

 from 7 to 9 days, and the beetles live under laboratory conditions from 6 to 

 8 months, during which period as many as 93 eggs have been recorded from a 

 single beetle. At Padung the eggs were severely parasitized, 62 per cent being 

 recorded. 



The application of a 2 per cent solution of lead arsenate was found to be 

 the most effective in destroying both the adults and larvce. 



Biological notes on the flat-headed apple-tree borer (Chrysobothris femo- 

 rata) and the Pacific flat-headed apple-tree borer (C. naali), H. E. Burke 

 (Jour. Econ. Ent., 12 (1919), No. 4, pp. 326-330) .—The author has found C. mali 

 to be far more common and injurious in the Pacific States than C. femorata. 

 " Numerous rearings have given us C. femorata from the prune and plum a few 

 times and C. mali from the currant, apple, plum, prune, cherry, peach, and apri- 

 cot a number of times. C. mali is also more common in shade trees and 

 brush forests, while C. femorata is commoner in the oaks and. the aspen for- 

 ests of the high Sierras, C. femorata occurs throughout the United States, 

 and C. mali has been reported from Oregon, California, Nevada, Utah, Colo- 

 rado, and Arizona. Many of the published records of damages by C. femorata 

 in the Rocky Mountains and the Pacific States undoubtedly refer to damage by 

 C. mali." 



Notes on forest insects. — I, On two bark beetles attacking the trunks of 

 white pine trees, M. W. Blackman (Psyche, 26 (1919), No. 4, pp. 85-96, pi. 1, 

 fig. 1). — The biological observations here reported relate to Ips longidens, 

 which in central New York works on the inner bark of white pino, aild Hylur- 

 gops pinifex, which attacks white pine l)y preference. 



Weevils in Australian wheat in California, R. W. Doane (Jour. Econ. Ent., 

 12 (1919), No. J,, pp. 308-312). — The author has found the rice weevil to be the 

 most common l)eotle occurring in shipments of Australian wheat. In some 

 lots the granary weevil was also very abundant, in other shipments but few 

 were found.
