INTRODUCTION 21 



this plant the following representatives of the family were se- 

 cured : Chilosia occidental's Will., Chilosia -plutonia Hunter, 

 Melanostoma mellinum (L.)> Syrphus amalopis O. S., Syrphus 

 mentalis Will., Syrphus diversifies Macq., Neoascia globosa 

 Walk., and Brachyopa notata O. S. Several Syrphids were 

 also taken at the flowers of Nephrophyllidium cristagalli 

 Myiolepta bell a Will, and Eristalis occidentals Will. 



Of the 47 species of Diptera captured at Virgin Bay all but 

 14 had been previously encountered at more southern stations, 

 but among the unfamiliar forms Mr. Coquillett found several of 

 considerable interest, including Ornithodes harrimani y a Tipulid 

 for which he found it necessary to erect a new genus ; Cylin- 

 drotoma juncta sp. nov. Coq. ; Empis jtellucida sp. nov. Coq., 

 3j\diRhamphomyia macrura sp. nov. Coq., new types of Empidae ; 

 and Ceratopogon hirtulus sp. nov. Coq., an addition to the family 

 Chironomidse. 



Of Coleoptera very few were collected, and the Hemiptera 

 are represented by a single Capsid. 



Among the Hymenoptera may be mentioned Bombus mix- 

 tuosus sp. nov. Ashmead, here seen for the first time, but col- 

 lected later at stations farther west. The specimens were taken 

 at the flowers of Rubus spectabilis. Upon a promontory jut- 

 ting out into the bay was a considerable patch of Menziesia fer- 

 ruginca, among whose bell-like blossoms Vespa borealis Kirby 

 was found busily extracting nectar. Of saw-flies the collection 

 yielded six species, but none of these were of special interest. 

 Several parasitic Hymenoptera were collected, including Ichneu- 

 mon kincaidii sp. nov. Ashmead and Zclotypa alaskensis sp. 

 nov. Ashmead, the latter one of the Proctotrypidas. 



At this locality Odonata were first noticed in considerable 

 numbers. Two species were on the wing, but of these only 

 one was captured Leucorhinia hudsonica (Selys.). 



ORCA, PRINCE WILLIAM SOUND 



June 24-25 and 2728. Short stops, mainly at night, were 

 made at this point, where an extensive salmon cannery has been 

 erected. The district is so mountainous and inaccessible that 

 very few insects were taken.
