and A. canora. There are two forms of A. arcta, one with yellow and the other with 

 red wings, though the former is the most common.] 



[21. Arphia pulchripennis, sp. n. 



Very similar in general appearance to A. aberrans, but differing from that insect in having the disc and costal 

 margin of its wings bright transparent brick-red, instead of greenish-yellow. Its hind femora are more 

 robust and inflated, and the hind tibiae of a much deeper blue, the banding of the former being more 

 decided, while the dorsum of the abdomen is without the bluish hue mentioned in connection with 

 A. aberrans. The pattern of the wing-bar is very nearly the same in the two forms, and both have the 

 X-shaped pale marking on the disc of the pronotum. 



Length of body, 3 , 23 ; of pronotum 5'15, of tegmina 23, of hind femora 12 millim. 



Hab. Noeth America, vicinity of Los Angeles, California (A. Koebele). 



The present species, as will be seen by a reference to the synoptic table, is also 

 quite closely related to A. arcta, A. teporata, and A. canora. A single male.] 



[22. Arphia teporata, Scudd. 



Arphia teporata, Scudd. Ann. Rep. Chief Eng. 1876, p. 508 (1876) \ 



Hab. North America \ Texas (8. H. Scudder), Silver City, New Mexico (coll. 

 L. Bruner). 



After studying a number of specimens of closely allied forms, the writer has 

 concluded to separate them as indicated in the synoptic table. The present species is 

 red-winged, while its nearest ally, A. arcta, may be either red- or yellow-winged. The 

 latter has a more northerly habitat and is also more widely distributed ; it is a spring 

 insect, living over winter as a nymph.] 



23. Arphia palHdipennis, sp. n. 



Very like A. arcta, Scudd., in general appearance, but differing from it in its somewhat slenderer form, the 

 very faintly coloured wings, and the deep blue hind tibiae. A. palHdipennis also differs in having the 

 median carina of the pronotum heavier and more prominent, while the pronotum itself is shorter and 

 more coarsely, though less closely, granulose than in the species to which it is here compared. The 

 wings have the dusky band, although very faint, continued to the front margin ; the coloured disc and 

 anterior field is very pale yellow, almost hyaline ; and the apex is vitreous. 



General colour of the insect pale greyish-brown, becoming darker anteriorly about the base of the tegmina, 

 thorax, and head. The tegmina have their dorsal edge testaceous and free from the small scattered 

 darker mottlings present on the rest of their surface. Hind femora of moderate length and robustness, 

 somewhat varied in the ordinary manner with lighter and darker shades, the lower sulcus pale, the inner 

 face black and pale-banded. 



Length of body, <$ 18, $ 27 ; of antennge, 6 7*5, $ 7 j of pronotum, <$ 4-15, $ 5*5 ; of tegmina, <$ 18, 

 $ 23 ; of hind femora, <$ 12-5, $ 14 millim. 



Hab. Mexico, Coatzacoalcos in Vera Cruz (C. C. Deam : d ), Eslava (0. W. Barrett : 2 )• 



The types, which are in the author's collection, are the only specimens at hand, but 

 the great difference in the climate and altitude above sea-level that exists in these two 

 localities would indicate a fairly wide distribution for the species.
