156 EXPERIMENT .STATION EECORD. 



Tlie pnpa is formed within a cocoon made in tlie same location in wliich tlie 

 larva fed. The moth emerges in 2 or 3 weeks. 



Of 5 other species of Ereunetis which occur in Hawaii and here noted, 3 

 are described as new to science. Four species of Opogoua are noted of which 

 2 are described as new. The so-called dancing moth, an undetermined species, 

 is abundant in Oahu, its larvre often being found in sugar cane associated with 

 larvae of the bud moth. The larvfe of Autosticha pelodes are sometimes asso- 

 ciated with budworms in the cane, l)ut probably do no injury. The larvae of 

 Batrachcdra rUcyi has been found feeding beneath leaf stalks of dead cane and 

 also in bored cane stalks. Crr/ptohlabcs alicna, which is described as new to 

 science, appears to be a general feeder. 



Three parasites, Siet-ola molokaietisis, Melittobia haivaiicnsis, and Microdus 

 hatcaiicola have been bred from the budworm. The red ant (Pheidole megace- 

 phala) destroys more or less of the young budworms and of the other moths 

 here considered. Several species of Odynerus have been observed in cane fields 

 hunting for budworms and other tineid larvae. It is said that the injury done 

 by the eating out of the eyes of the cane is not sufficient to warrant any exten- 

 sive operations against the budworm. 



Observations on the habits and injury of the asparagus fly (Platyparea 

 poeciloptera) in the vicinity of Paris, I\ Lesne {Compt. Rend. Acad. 8cL 

 [Paris], U8 (1909), No. S, pp. 191-199).— Thin fly is said to be the source of 

 injury in a large territory to the north of Paris, but does not seem to have made 

 its appearance to the south. Emphasis is placed upon the importance of the 

 destruction of all affected shoots as soon as they wither. 



Biological investigations of the viviparity and larval life of Glossina pal- 

 palis, E. RouBAUD {Compt. Rend. Acad. Sci. [Paris], IJ/S {1909), No. 3, pp. 195- 

 197). — This is a brief report of biological investigations of the tsetse fly. 



Distribution of certain species of biting flies in the Federated Malay States, 

 H. C. Pratt {Jour. Trop. Yet. Sci., 4 {1909), No. 3, pp. 390-39J,).— This is a 

 brief report on a large number of flies of the family Tabanidae and of the 

 genus Stomoxys, which were obtained in various parts of the Federated Malay 

 States in connection with the work on surra. 



Report on the mosquito work for 1908, J. B. Smith {Neio Jersey Stas. Rpt. 

 1908, pp. 381-428, pis. 2). — The season of 1908 is said to have been an abnormal 

 one in many respects and favorable to the development of mosquitoes of all 

 kinds. In the expenditure of the appropriation of .$20,000, an area of 6,669 

 acres was drained, 888,650 ft. of ditching being dug. From a study of mos- 

 quito eggs on salt marsh, it is concluded that an individual ovum may main- 

 tain its vitality for 2 or even 8 years. It was found that in the same woodland 

 pool, 3 different species may appear in 3 successive years, each species by 

 itself and without any admixture of the species that was in the same pool at 

 the corresponding time in the previous year. 



Due to the favoi-able season the house mosquito was so abundant in the 

 larger cities that the benefits derived from the absence of the salt-marsh mos- 

 quito were not fully appreciated. 



Notes made by J. T. Brakeley on Culex perturMns are presented. The first 

 larvae of this species were collected on March 7, at which time 6 well-grown 

 individuals were washed out, having evidently been attached to the floating roots. 

 It thus appears that they freeze and thaw out with the floating vegetation. It 

 is concluded from the observations that the pupae of this species never volun- 

 tarily come to the top in a state of nature, but that the adults emerge under 

 water and pop up to the surface;
