214 PROCEEDINGS OP JSE ACADEMY OF 



A local race of Juno, differing but sligbtlj from the Equadorea'n form Audi- 

 cola; these are constant, however, in regard to the coloration and shape of the 

 wings ; in the latter respect, it approaches more nearly to Lucina, Felder. 



15. Euterpe arechiza, nov. sp. 



Male. Fore wings narrawer and more sinuate than in Bithys; the brad wings 

 dentnte. Upper surface brownish- black, traversed by two maculate, white 

 bands ; the first extends from the outer third of the costa of the fore wings, to 

 the middle of the abdominal margin of the hind wings, consisting on the first 

 of eight widely separated spots, on the last the band is broken only by the 

 dark veins ; the second band is formed of small rounded white spots, running 

 obliquely from the costa of the primaries to their inner angle, and sub-margin- 

 ally all equidistant from the border, on the disc of the secondaries ; there 

 are also some minute white terminal streaks at the apex of the fore wings, 

 and some marginal ones in the middle of the hind wings' interspaces. 



Underneath pale brown, with darker shades between the veins of the hind 

 wings ; the terminal streaks on the outer margin of the primaries are yellow- 

 ish. The inner band, of the secondaries is striped narrowly with yellow lines, 

 beside which there are some small spots and dashes near the base, and the 

 submarginal and marginal rows, all yellow ; there are also two red basal 

 patches. Expanse 1-75 2 inches. 



Body and antenna? as in Bithys.

A local race of Exit. Bithys. In addition to the differences in ornamentation 

 , and the shape of the wings, I have found that in Arechiza the disco-cellulars 

 of the fore wings form but a very slight angle with each other, and the second 

 subcostal veinlet of the secondaries is invariably thrown off much nearer the 

 base than in Bithys; the difference in distance being fully eqnal to one-half 

 the distance between the first and second subcostal veinlets of the latter 

 species. 



;16. Lyona catalina, nov. sp. 



Male. Upper surface brown, glossed with violet blue, except a broad terminal 

 border on both wings. Fringes white, cut with brown. 



Under surface ash-brown, darkest at the base of the secondaries, more di- 

 luted on the outer margin of the primaries. 



The fore wings have two spots within the cell, one at its extremity, the other 

 nearer to the base; a submesial sinuated row of six rounded and oblong 

 spots ; and a submarginal row of six lunes ; all brown, or blackish-brown en- 

 circled with white ; the outer row is usually incomplete, and sometimes almost 

 obsolete. 



The secondaries have the main portion of the cell occupied by a large 

 whitish spot, running up to 'he base, and having a rounded black spot in its 

 centre. Between this and the outer margin there is a broad and similarly 

 colored belt, formed of confluent sagittae, each of which is preceded by a 

 rounded black dot, encircled with white, and followed by a narrow black 

 crescent. Below the third of these from the inner margin, there sometimes 

 appears an ochreous lune, upon which is impinged posteriorly a brown bar, 

 tapering gradually to the hind margin. There is another white-ringed black 

 spot on the costa, above the similar one within the cell. "Expanse 1-13 1-20 

 inches. 



Body blackish-brewn above, with some blue hairs on the thorax, under- 

 neath cinereous. Antennae black, ringed with white ; club tipped with the 

 same. 



Female, appears to differ only in the greater size ; expanse 1-25 1-30 

 inches. 



Hab. California. (Coll. Tryon Reakirt.) 



17. Lycena monica, nov. sp. 

 Male. Upper surface rosy violet, covered with an ashy hue, darker towards
