THE CANADIAN ENTOMOLOGIST. 91 



Related to M. Mice, Nort., from which it may be separated by the 

 truncate clypeus, white bands of the abdomen and other characters. 



Labidia Doanei, n. sp. — $. Length, 6.5 mm.; robust. Clypeus 

 large ; very slightly, broadly emarginate ; punctured like front. Labrum 

 rounded at the apex, rather large. Head closely, rather coarsely punc- 

 tured, cheeks not so strongly so. Lateral ocellar furrows more or less 

 distinct from occiput to antennae. Middle fovea indicated by a shallow 

 circular impression. Antennae as usual for genus ; third joint as long as 

 4 + 5. Thorax not as coarsely punctured as the head. Stigma rounded 

 on the lower margin, a little broader at the base. Third cubital cell as 

 long on the cubitus as the length of the third transverse cubitus ; about a 

 third longer at apex than at base. Claws deeply cleft, teeth equal. Basal 

 plate not divided in the middle, or, at least, not strongly so. Sheath 

 straight above, rounded below, but not strongly so, black. Palpi, 

 tegulae, angles of pronotum, scutellum sometimes, apical margin of basal 

 plates, apical margin of dorsal and ventral abdominal segments and the 

 sides of all the segments creamy -yellow. Legs mostly creamy-yellow, but 

 the following are black : coxae, trochanters, a line above on the femora 

 and tibiae (sometimes interrupted on the tibiae), and the tarsi, except 

 beneath on the anterior ones sometimes. Wings hyaline, slightly 

 iridescent; venation dark brown, the costa and stigma reddish-brown. 



Habitat. — California. Specimens from Stanford University, March 

 9, 1905 ; Palo Alto, March 31, 1893, and April 27, 1895. 



Named in honour of R. W. Doane, who kindly sent the specimens. 



This species is at once known from L. originates, var. opimus, Cress., 

 by the smaller size, the black and almost truncate clypeus, the broader 

 and more rounded stigma (the stigma of opimus. Cress., is rather slender 

 and elongate), the shorter third cubital cell and other characters. 



Labidia originates, var. opimus, Cress. — I have examined specimens 

 of this species from the following localities : 20 9 9 above Silverton, Colo., 

 July, '03, alt. 12,000 ft. (C. R. Jones) ; $, Graymont, Colo., July (C. P. 

 Gillette) ; Steamboat Springs, Routt Co., Colo., July (C P. Gillette) ; ? , 

 Home, Colo., Aug.; Gore Pass, Colo. (C. P. Gillette) ; Cameron 

 Pass, Colo. (C. P. Gillette) ; Little Beaver Creek, Larimer Co., Colo., alt. 

 9, 100 ft. (C. P. Gillette). The above specimens are in the collection of 

 the Colorado Agricultural College. ? , Ute Creek, Costilla Co., Colo., 

 alt. 9,000 ft., July 1, 1907; o f Russell, Costilla Co., Colo., July 12, 1907.
