Arphia Stal. 



Kansas forms of medium size; body more or less compressed, varying 

 from light grayish to dull fuscous in color; scutellum of the vertex as 

 in type A. hippiscus; carina of the pronotum usually well developed, not 

 cut by the sulci, sometimes faintly sinuate; disk of the pronotum finely 

 granulate to regulose; tegmina ample, coriaceous, densely and irregularly 

 reticulate; base of wings bright red or yellow with a dark arcuate band, 

 spur either long or short, wide or narrow; apically the wing is hyaline 

 or infuscated; inside of hind femora dark with lighter stripes. 



All of the Kansas forms look very much alike in general appearance 

 and with the aid of the key will not be especially difficult to separate. 



Arphia simplex Sc. 

 Proc. of the Soc. Nat. Hist., vol. 17, 514; 1875. 



Brownish fuscous. The general color is very uniform, but the lower 

 half of the head, and especially the face, passes to ashen; lateral 

 foveoke of the head scarcely distinguishable from the parts below, the 

 lower limits being very obscurely marked. The edges of the lateral lobes 

 of the pronotum are sometimes dotted irregularly with yellowish ; pro- 

 notum somewhat scabrous; pronotal crest not high nor arched uniformly; 

 tegmina flecked with fuscous dots pretty uniformly distributed over the 

 whole, excepting in being a little crowded in the basal half of the 

 middle area; wings at base red, with a slight orange tinge, bounded 

 by a moderately broad, nearly equal, arcuate, dark fuscous band, padding 

 from the middle of the outer half of the costal border nearly at right 

 angles to the same, until it reaches the outer border, when it curves 

 inward, following the border more than half the way to the anal angle; 

 it sends inward, fully half way to the base of the wing, a broad generally 

 tapering shoot just below the costal margin; beyond the arcuate band 

 the wing is fuligno-pellucid, and at the tip fuliginous, all the veins dusky; 

 hind femora vary indistinctly transversely trifasciate with an indis- 

 tinct pale annulus just before the tip, the hind tibiae obscure glauco- 

 plumbeous, with a pale annulus near the base. 



Length of body, male 24.5 mm., female 32 mm. ; of antennas, male 

 9 mm., female 9.5 mm.; of tegmina, male 26 mm., female 31 mm.; of 

 hind femora, male 16 mm., female 18.5 mm. Two males taken June 

 the third and sixth, one female taken April 26, in Dallas, Texas, by 

 J. Boll. 



This is the commonest Arphia in our state, appearing early in the 

 spring and lasting throughout the summer. The very peculiar, broad 

 lateral foveolae of the vertex separate it very effectively from other 

 species.
