 OH 14; i)ronotum: L 11, W 19; tegmen 13-46. 



Described from the type specimen. 9 ; Tucson, Arizona, April 

 4, (R. E. Kiinze), [No. 3441, U. S. N. M.]. 



Erythroneura bipunctata Gillette, dark form 



This is the form mentioned by Gillette, (loc. cit.) in the follow- 

 ing quotation: "I have received an additional female from Dr. 

 Kunze taken at the same place April 30. It differs from the type 

 in being nearly a half millimeter longer and having smoky brown 

 coloration in place of the red." 



Erythroneura bipunctata Gillette, yellow form 



Like the red form except that ground color is pale yellow and the markings 

 greenish-yellow. This small contrast sometimes results in various parts of 

 the insect appearing almost unicolorous; the legs are stramineous. Costal 

 plaques opaque whitish, inconspicuous in the more deeply colored specimens. 



Length, 2.5 mm.; vertex: LM 4, LE 3, WA 11, WP 19; OA 5.5, OP 11, 

 OH 14; pronotum: L 11, W 20; tegmen 13-51. (Measurements from a
