Myodites knausi n. sp. 



The specimens on which this description is based are from 

 the collection of Mr. Warren Knaus, and include four females 

 collected at St. George, Utah, June lo, 1919, at an altitude 

 of 2800 feet; and two females and one male collected at Hurri- 

 cane, Utah, June 14-18, 1919, at an altitude of 3200 feet. 

 I have chosen as types the male and one female from Hurri- 

 cane. 



9 : Length 9 mm.; Head shining black, depressed, finely and evenly 

 punctulate, clad with dense yellowish white perpendicular pubescence; 

 vertex prominent, broadly rounded; eyes shining black, minutely facetted. 

 Antennae ten-jointed, nine-flabellate, pubescent; joints honey-yellow, 

 darkening toward apex, the last joints almost entirely brownish; the 

 flabellae diminishing in length toward apex, but the flabella of the tenth 

 joint equals the basis of the three preceding joints. Mandibles with the 

 exterior side black, punctulate, densely pubescent, beyond which there 

 is a slight reddish tinge, apices shining glabrous, acuminate. Palpi 

 yellowish, tinged with brown, pubescent. 



Prothorax black, shining, more or less denuded in scutal zone, densely 

 pubescent at base, sides and in scutellar sone; irregularly punctulate, 

 not carinate. Elytra honey-yellow with brownish base. Metathorax 

 shining glabrous. The thorax beneath and on sides is minutely punctu- 

 late and densely pubescent. Wings hyaline, with large fuscous cloud on 

 costal margin and on disc beyond middle. 



Legs honey-yellow, with joints darkened at base and apex, tarsal 

 joints darker. Femora stout, densely pubescent, shining and minutely 

 punctulate. Tibiae straight, slightly enlarged toward tip, bi-unguicu- 

 late, densely pubescent, and rather c osely and minutely punctulate. 

 Anterior tarsi with first joint slightly longer than following three, fifth 

 longer than first, claws almost as long as first joint, and strongly pecti- 

 nate. Middle tarsi with first joint as long as fifth joint, claws strongly 

 pectinate, but not as long as first joint. Hind tarsi with first joint elong- 

 ate, enlarged, and apically diagonally truncate, almost twice as long as 

 the two following joints, and longer than the fourth joint; claws two- 

 thirds as long as the fourth joint, and strongly pectinate. 



Abdomen with dorsum of first five segments black, but with interseg- 

 mental skins yellow. The venters of these same segments are also black 

 with yellow inter-segmental skins. The pygidial area is yellow with 

 infuscation beyond the middle. The entire surface of the abdomen is 

 sparsely punctulate pubescent. 



c? : Length 9 mm. Similar to the female, with the following exceptions: 

 antennae honey-yellow, bi-flabellate, with the tips of the rami about even. 

 The abdomen is black with the base and apex of the first ventral segment 

 yellow, and the prepygidial area yellow, but with the pygidium black.
