Malthodes vigilans sp. nov. 



Piceo-testaceous, head darker, thorax yellow. Antennse fuscous, 

 slightly longer than the entire body in the male, joints 2-4 increasing 

 in length, the third however, only slightly longer than the second; 

 intermediate joints (cf ) about five times as long as wide, ( 9 ) twice as 

 long as wide. Head much wider than the thorax in the male, scarcely at 

 all so in the female; eyes (cf ) very large and prominent, separated in 

 front by but little more than their own width. Thorax moderately 

 transverse, a little more so in the female as usual, sides parallel, feebly 

 margined, the margin just perceptibly thicker at the front angles, 

 surface scarcely visibly punctate. Length about 3 mm. 



Abdominal sexual characters. Male with sixth ventral deeply, 

 broadly emarginate, seventh rather short and broad, projecting beyond 

 the sixth a distance less than the length of the latter, the tip deeply 

 narrowly incised. Last dorsal not projecting beyond the last ventral. 

 Female as usual. 



California. San Bernardino Mts., July; 2cf, 19, collected 

 by the writer. The type is a male. 



Malthodes basalis sp. nov. 



Fuscous, front anteriorly yellow, pro thorax varying from yellow 

 with faint diffuse fuscous discal cloud, to nearly evenly fuscous with the 

 extreme basal and apical edge yellow. Antennae fuscous with basal two 

 joints yellow, as long as the body in the male, joints two to four increas- 

 ing slightly in length, intermediate joints about three times as long as 

 wide. Head (cf ) slightly wider than the thorax, the eyes only mod- 

 erately prominent, separated in front by twice their own width or 

 slightly less. Thorax moderately transverse, sides parallel, narrowly 

 margined, the front angles scarcely more prominent. Length 2 to 3 mm. 



Abdominal sexual characters. Male: sixth ventral deeply emarginate; 

 seventh broad, nearly straight in profile, extending beyond the sixth 

 a distance subequal to the length of the latter, the tip broadly emar- 

 ginate; last dorsal not produced. 



California. Yosemite, June 16 (W. M. Giffard), sent by 

 Dr. Blaisdell; Licking Fork, Mokelumne River, June, (Blais- 

 dell); Lake Tahoe, July 17-21. 



Nevada. Ormsby Co., July (Baker). 



Fifteen examples are before me. The type is a Yosemite 

 male. 



The bright yellow^ basal two joints of the antennae will 

 probably serve to separate this from the other California species.
