282 THE CANADIAN ENTOMOLOGIST 



Empidida?, 7 sp. (all Rhamphomyia, 5 new); Dolichopodidae, 6 sp. (1 n. sp. 

 each in Dolichopus and Hydrophorus) ; Phoridse, 3 sp. (all Apiochseta, 2 n. sp.); 

 BorboridiE, 1 sp., a new Leptocera; Syrphidac, 8 sp.; Oestridse, 2 sp.; Tachinidse, 

 2 sp. (1 new Peleteria) ; Calliphoridse, 4 sp. (1 new Phormia); Anthomyiids, 

 26 sp. (n. sp. in Phaonia, 1 Mydaeina n. gen., 1 Aricia, 1 Hydrophoria, 1 Alliopsis, 

 1 Hylemyia and 1 Phorbia) ; Scatophagidse, 8 sp. (1 n. sp. each in Gonatherus 

 and Cordylurella, n. gen., Dasypleuron n. gen., and Allomyia n. gen.; Helomy- 

 zida?, 3 sp. (1 n. sp. each in Oecothea and Neoleria) ; Piophilidae, 1 sp. (a new 

 Piophila) and Chloropidae, 1 sp. 



Much of the material in the collection was specifically indeterminable, so 

 that it is probable that it contains a considerable number of undescribed species. 



This paper also contains keys to the genera of Phaoninse and Anthomyiinae, 

 and to those of the entire family of Scatophagidse and Helomyzidae. 



Part D, Mallophaga and Anoplura. Mallophaga; by A. W. Baker; Ano- 

 plura, by G. F. Ferris and G. H. F. Nuttall. Twenty species of Mallophaga 

 are listed from 13 bird hosts and one mammal. All belong to described species 

 with the possible exception of three species which were too immature for specific 

 determination. Four of the species are illustrated on the plate. Only three 

 species of true lice or Anoplura were taken, one of these being the human head 

 louse, collected from the head hairs of copper Eskimos. 



Part F, Hemiptera, by E. P. Van Duzee. Pp. 1-5. The scarcity of 

 Hemiptera in the Arctic regions is indicated by the small size of the collection, 

 which consists of but 12 species. Only 6 of these were specifically determinable, 

 one species being described as new, viz., Euscelis hyperboreus, n. sp. 



Part H, Spiders, Mites and Myriopods. Spiders, by J. H. Emerton. 

 Acarina, by Nathan Banks. Chilopoda, by Ralph V. Chamberlin. 



Spiders (pp. 1-9, pis. I-III). The collection of spiders include 13 species 

 of which three are described as new. They are distributed among the follow- 

 ing genera: Erigone (1), Typhlocrsestus (1), Tmetocerus (2, 1 n. sp.), Microveta 

 (2, 1 n. sp.), Epeira (1), Dictyna (1), Lycosa (2, 1 n. sp.), Pardosa (2), and 

 Xysticus (1). 



Descriptive and distributional notes are given on many of the species and 

 structural details of most of the forms are figured. 



Acarina, (pp. 11-13). The mites belong to 7 families, 14 genera and 17 

 species, only one of which is described as new. {StigmcBUS arcticus, figs. 1 and 

 2). They belong to the genera Rhagidia (1), Bdella (3), Bryobia (1), Stigmaeus 

 (1), Trombidium (1), Eylais (1), Hydrophantes (1), Thyas (1), Lebertia (1), 

 Laminipes (1), Curvipes (1), Parasitus (1), Galumna (1), and Scutovertex (2). 



Chilopoda (pp. 15-22, pi. IV). Two species of Chilopods, one belonging 

 to the Lithobiomorpha, the other to the Geophilomorpha, are the only Myrio- 

 pods collected by the Expedition, and both were taken in the Cape Nome region, 

 Alaska. Mr. Chamberlin, however, gives a list of all the Alaskan Chilopods 

 (14 species), a key to the genera of the family Chilenophilida^, and a full de- 

 scription of Cryophihis alaskanus. n. gen. et sp. Ethophihts integer, n. sp., 

 though not represented in the collection of the Expedition is also described, a 

 subspecies {alaskanus) having been reported from Alaska. The typical form 

 comes from Washington and Oregon. • E.M.W.
