Key to the Color Varieties 



A. Averaging larger (2.9 to 3.46 mm.); pronotum and scutellum chiefly 

 yellow; tegmina usually with considerable red markings.

 AA. Averaging .smaller (2.64 to 2.97 mm.); pronotum and scutellum chiefly 

 dusky; tegmina with few or no red markings.

Erythroneura tecta var. tecta new variety 



Ground color of scutellum and anterior parts pale yellow; vertex with two 

 round dusky spots on disc which are more or less connected with each other, 

 with inner side of orbits, and with posterior margin by arcuate reddish mark- 

 ings; pronotum with an angulate brown vitta sometimes broken up into 

 dusky spots on each side, and two discal spots sometimes concealed by reddish 

 markings, which when fully developed form a U based on posterior margin; 

 scutellum with basal triangles black, margins and apex reddish; tegmina 

 whitish hyaline (dorsal pale areas more or less opaque); claviis is perhaps 

 best described by saying it is red, sometimes brownish, except the whitish 

 hyaline extreme base, a large more opaque whitish or pale yellow area near 

 scutellum and entirely within claval (second anal) vein a smaller whitish area 

 overlapping apex of last but entirely outside claval vein, and a small trans- 

 verse whitish band just before apex; corium more or less bluish or dusky be- 

 tween veins, the veins often reddish; two whitish areas bounded by red be- 

 tween third sector and claval suture, costal plaque pale yellow, more or less 

 overlaid by opaque white, bounded at both ends by dusky clouds, costa 

 hyaline posteriorly, interrupted by red cross-vein; apical cells fumose with 

 a darker area at base of fourth cell and another at apex of wing, common to 

 second and third cells, often forming an oblique vitta. Face pale yellowish 

 a dark spot on base of clypeus, two others above just within antennal bases, 

 lower surface of vertex marked by a few reddish lines; legs pinkish livid; 

 body slaty, or with pale yellowish edgings.

Erythroneura tecta var. carbonata new variety 



A smaller, dusky form, the scutellum and pronotum especially being mucli 

 darker than in the typical variety, the tegmina with much less red, the tip of 

 clavus and margin of pale spot near base of clavus, however, sometimes red.
