time the larva of Twnia ciicumerina, reported to occur in Pulex serraticeps and 

 P. irritans, lias been the only one known to occur in fleas. The author now 

 describes a cysticercoid found in the abdominal cavity of Mesopsylla eucta 

 n. sp., a flea found on the jerboa (Alactaga jaciilus) of Turkestan and from 

 which tapeworms have not hitherto been recorded. The hooks of this parasite 

 are said to be like those of HymeiioleiHs nana.

The large larch sawfly, E. Henry (Rev. Eaux et Forets, !t9 (1910), No. 23,

On the morphology and ontogeny of the Acaridse with particular consid- 

 eration of Pediculopsis graminum, E. Eeuter (Acta Soc. Sci. Fennicce, 36 

 (1909), No. 4, PP- 288, pis. 6, figs. 12). — The author considers the subject in the 

 following manner: (1) The Ecology of P. grammum (pp. 5-16); (2) The 

 Morphology of the Acaridae (pp. 17-114) ; (3) The Ontogeny of the Acaridse 

 (pp. 115-231) ; and (4) Remarks upon the Classification and Phylogeny of the 

 Acaridse (pp. 232-288). 



A bibliography of the literature relating to the subject is appended. 



A new filarial species (Filaria mitchelli n. sp.) found in Heloderma 

 suspectum and its larvae in a tick parasitic upon the Gila monster, A. J. 

 Smith (Univ. Penn. Med. Bui., 23 (1910), No. 9, pp. 487-497, figs. 9).— Four of 

 7 living Gila monsters from Arizona examined by the author were found to be 

 infested by filarial larvse of the species here described as new. Living and 

 actively moving filarial worms were found in ticks attached to this host. 

 Whether the tick is a true immediate host or whether the larval filarise taken 

 into the tick with the blood abstracted from the primary host are eventually 

 destroyed, has not yet been determined. 



Spraying as an essential part of profitable apple orcharding, R. A. Emer- 

 son, R. F. Howard, and V. V. Westgate (Nebraska Sta. Bui. 119, pp. 3-26, 

 figs. 8). — This bulletin discusses the cost of, and results obtained from, spraying 

 small orchards, cooperation in spraying small orchards, and gives directions for 

 the preparation and application of insecticides and fungicides. The authors 

 report that during the past 5 years demonstrations have been made in 22 

 orchards, representing 18 localities in 13 counties of the State.
