compared with various other species of Lucoppia. one is at a 

 loss as to where to draw the line of generic distinction. Cer- 

 tainly one would hardly conclude that Halozetes has very little 

 of affinity TC'/.'/I other genera known from arctic regions. Even 

 the tyjje of Berlese's genus Lucoppia, the old Zetes lucornm 

 Koch, which occurs throughout all Europe and most of North 

 America, is found in Spitzenbergen. The truth of the matter is 

 that species rather closely related to Halozctes antarctica 

 (Mich.) and H. belgieac (Mich.) are of practically worldwide 

 distribution. The genus is practically cosmopolitan. The writer 

 has described one species from decaying leaves and trash col- 

 lected at Columbia, Missouri, another from decaying mush- 

 rooms at Jordan, Minnesota ; another from moss, Nilgiri Hills, 

 India, while our Lucoppia pilosits (Banks) is probably found 

 throughout most of North America under a variety of condi- 

 tions. 



In closing these notes the writer wishes to state that accord- 

 ing to his opinion, we are hardly justified in making any state- 

 ment at present to the effect that the Antarctic Region supports 

 a distinctive mite fauna that is of any significance whatever. 

 Doubtless a more complete survey will bring more interesting 

 and, very probably, quite remarkably distinct and character- 

 istic mite species to our attention. At least we would expect 

 so if we should draw any analogy from the bird fauna of this 

 region, which is remarkably distinctive and characteristic in 



many respects. 







Prosimulium fulvum Coquillett a Biting Species (Dip., Simuliidae). 



In his report on the Black Flies, Mr. J. R. Malloch says* with regard 

 to this species: "There are no records of whether or not it hites either 

 man or animals." This being the case it seems desirahle to publish some 

 notes given by Mr. A. H. Twitchell regarding the species, specimens of 

 which were collected by Ir'm along Fourth-of-July Creek. Alaska, July 

 20, 1 ( )21. He states: "They are not very common but I could get. a 

 hundred of them at that place in an hour. They bite horses about the 

 ears, inside or out and at times they bite around the eye and also go 

 into the mane. I have seem them on no other stock than horses, but 

 one bit me on the car." 



Prosimulium fith'itin Coiiuillett ranges from Alaska south to British 

 Columbia, Montana and Colorado. It is the largest species of the fam- 

 ily in this country and the only yellow species known to occur in 

 Alaska. W. T.. M< ATI-F. t". S. Biological Survey. Washington, D. C.
