 distinct species. 



Erythroneura obliqua var. parma new variety 



Like variety obliqua except that scutellum is entirely red, marked with 

 an incomplete and interrupted median pale vitta and with two nearly tri- 

 angular black spots within the basal angles; costal plaques creamy yellow; 

 face yellowish above, pinkish below : genitalia reddish laterally.

Erythroneura obliqua var. noevus (iillette 



TyphUH'Iq/ha obliqua var. noevus. Gillette, C. P. Am. Typhlocybinae, 

 189S, i)p. 757 to 758. [Onaga, Kansas.] 



The original descrii)tion states that this ''variety has the typ- 

 ical red lining, l)iit the scutellum and hind margin of the pronotum 

 are more or less black" (p. 757). In view of this statement the 

 selection of the type (type no. 3444, U. S. N. M.) was unfortunate 

 in that it is an individual having the color vittae of scutellum and 

 anterior dorsal surface, yellow. However, the inner tegminal 

 vitta is reddish, so that it is possil^le to class the type with the red 

 form of the variety as Gillette no doubt intended. 



The scutellum of this variety may have a more or less obvious 

 median pale area or vitta; the outer tegminal vittae may be more 

 or less yellowish and the undersurface is pale yellow with greenish 

 yellow to reddish markings.
