blackish-gray; wings grayish brown; eyes pubescent, first pos- 

 terior cell open. Length 13 to 14 millimeters. The t\'pe locality 

 is San Francisco, California. 



Pangonia incisa Wiedemann. First posterior cell closed, legs 

 and antennse yellow, ocelli present, proboscis slender longer than 

 the height of the head ; wings uniformly yellowish ; thorax dark 

 in ground color and clothed with yellow pile. In the female the 

 abdomen is black on the anterior part of each segment, and nar-

 yellow hairs. In the male the abdomen is yellow with black

 middle of the anterior half of the second segment. Length 14 to

Pangonia ruficornis Bigot. What appears to be this species 

 was received from Professor V. L. Kellogg, taken at Palo Alto, 

 California, July 27. Eyes naked, ocelli present; face, front, 

 antennae and palpi yellow; proboscis brownish, thickened, scarce- 

 ly longer than the slender palpi ; thorax reddish yellow, legs con- 

 colorous with the thorax, wings with a yellowish tinge, more pro- 

 nounced on the costal margin ; anterior l;)ranch of the third vein 

 with a stump at base. Abdomen yellow. Has the appearance 

 of being a very distinct species. Length 12 millimeters. 



Pangonia saussurei Bellardi. I have a single male specimen 

 that I have identified from Bellardi's description and figure as 

 this species. The specimen was taken in the Huachucas Moun- 

 tains of southern Arizona by Dr. R. E. Kunze. The antennae are 

 yellow, third segment slender, quite prominent at the base, pro- 

 boscis longer than the height of the head, palpi short and slen- 

 der, eyes naked, ocelli present. Thorax brown, clothed with gray 

 pollen and brown and gray pubescence; legs brown, anterior and 

 middle tibiae and tarsi a shade lighter than their femora; wings 

 dilute yellowish hyaline, with yellowish more distinct along the 

 costa and margins of some of the veins; a long stump at the base 

 of the anterior branch of the third vein ; first posterior and anal 

 cells closed. Abdomen in general grayish, with the anterior mar- 

 gin of each segment brownish ; posterior margin of each segment 

 with white hairs, remainder of segments clothed with black hairs. 

 Length 18 millimeters. 



Very distinct from the other species of the genus from our 

 fauna, but with some affinities with incisa. 



Pangonia velutina Bigot. I have not seen this speceis. Some 

 characters which Bigot gives are as follows: antennae yellow with 

 first two segments black, eyes naked, first posterior cell of wing 

 open, abdomen black, second segment with a large yellowish spot 

 on the middle of the posterior l)ordcr. Length 1 1 millimeters. 

 The type is from California.
