A NEW MOSQUITO. 



By Harrison G. Dyar, 



Washington, D. C. 

 Culex mitchellas, new species. 



This form was collected by me in southern Georgia and Florida in 

 temporary pools of fresh water. The adult resembles sollicitans, but 

 the wing scales are wholly black, the first tarsal joint is devoid of a 

 light colored median band and the light colored scales of the legs are 

 pure white instead of yellow. Types, 61 specimens, U. S. National 

 Museum, type No. 8407 ; one 9 selected as the type is from Jackson- 

 ville, Fla., the larvae in dirty recently dug holes along the railroad. 

 Other localities are Green Cove Springs in temporary pools in the 

 pines, Magnolia Springs in pools in swampy land, Kissimmee, in ditch, 

 puddles and pools at the edge of swampy land, Pokatee, Fla., in a hole 

 with old tin cans and rotton wood, and in the pine barrens of southern 

 Georgia in a puddle by the railroad at a siding. The larva closely re- 

 sembles that of sollicitans, but the air tube is considerably longer, being 

 fully three times as long as wide, while the spines of the comb are un- 

 usually long and thorn-shaped. 



It gives me pleasure to name this species in honor of Miss Evelyn 

 G. Mitchell. 



Class I, HEXAPODA. 



Order XI, ORTHOPTERA. 



THE COULEE CRICKET OF CENTRAL WASH- 

 INGTON. (PERANABRUS SCABRI- 

 COLLIS THOMAS.) 



By Robert E. Snodgrass,

(Plates I and II.) 



" Coulee Cricket " is a name that may be appropriately given in 

 the state of Washington to the large cricket-like Locustid, Perana- 

 brus scabricollis Thomas, that lives in such immense bands in the 

 northern half of Douglas county. The name is fitting because the 

 insects are found principally in or about the dry canons known as 

 coulees, the chief of which are two great gorges named Grand Coulee 

 and Moses Coulee.
