ART. 2;j A NEW SPECIES OF MOSQUITO DYAR 5 



AEDES DIANTAEUS Howard, Uyar, and Knab 



Adults wore taken by me in 1921 and larvae in several of the early 

 spring pools in 1926 in the Glacier Park. Some bred adults were 

 indistinguishable in coloration from communis, although the normal 

 form also occurs in the park. I have no other Montana records. 



AEDES INTRUDENS Dyar 



Breeding in the Glacier Park with diantaeus, the larvae fully as 

 rare in 1926. Owing to the habit of the adult of entering houses, 

 specimens of this species were taken almost every day to the middle 

 of July in the cabin of the North Fork Ranger Station, although 

 apparently passed out of doors. Mr. Mabee submitted specimens 

 bred at Darby, May 30, 1928, by Mrs. Dr. R. R. Parker from a 

 shaded pool in woods. Adults issued on June 3. 



AEDES PULLATUS Coquillett 



Breeding in the early spring pools at higher elevations in the 

 Glacier Park, but always a late inhabitant of them, the larvae lingering 

 after the communis and nearcticus had long emerged. Mr. Mabee 

 submitted specimens as follows: Chestnut, May 2, 1928 (G. Allen 

 Mail); Karse, W. Gallatin, May 3, 1928 (G. Allen Mail); Squaw 

 Creek, May 6, 1928 (G. Allen Mail); West Gallatin, May 24, 1928 

 (G. Allen Mail); Sedan, May 28, 1928 (G. Allen Mail); Ross' Peak 

 Ranger Station, May 28, 1928 (G. Allen Mail); King's Hill, June 11, 

 1928 (G. Allen Mail); Darby, May 30, 1928 (Mrs. Dr. R. R. Parker). 



AEDES TRICHURUS Dyar 



This species was common in the North Fork ranger station of the 

 Glacier National Park in the 1926 season. The station is on a high, 

 dry bank, 100 feet above the Flathead River, and no mosquito 

 breeding occurs in the vicinity. However, some 2 miles back at the 

 foot of the Apgar Mountains a large marsh occurs. There is also a 

 similar marsh across the river, outside of the park, near Lake Five. 

 This also is about 2 miles from the station in a straight line. Aedes 

 tricTiurus from these two foci, but especially from the latter, were 

 numerous, being the commonest mosquito at the station. Great 

 swarms of males were seen, first noted a mile from the Lake Five 

 marsh. The swarms broke up, crossed the river, and could be found 

 here and there in the forest in the park for several days. They 

 swarmed shortly before sunset, dispersing at dark. The females bit 

 at all times, day and night, though their approach was timid, and 

 they were easily driven away. 



AEDES EXCRtCIANS Walker 



This was the common ring-legged mosquito in the Glacier Park in 

 1926. Great numbers emerged from the marsh at the foot of the 

 Apgar Mountains near the North Fork station. Females were (lying 

 till August. Mr. Mabee submitted specimens labeled "Central Park 

 (flood water), June 5, 1928 (G. Alien Mail)."
