vol.. III.] A New Riimfordia. 241 



Sierra region in general or else cosmopolitan forms and those found 

 everywhere in the State. 



To the collector from the valley and coast regions of the State 

 this region is a new world. Here he first comes in contact with 

 large numbers of that family of Argynnid^e which makes the mount- 

 ains seem so full of insect life. This is by far the best represented 

 of any family in the mountains of this region, with reference both to 

 numbers and to species. Vanessa californica slightly outnumbers 

 it farther north, but is not seen in this locality. The genus Papilio 

 is also better represented here than in the lower regions. The spe- 

 cies of Thecla, Lycaena, Chrysophanus, Pieris and Colias are repre- 

 sented here as well as in the valleys. Parnassius and Chionobas are 

 of course mountain genera, seldom found at low altitudes. 



This short paper, with what has been done before by others, I 

 hope will induce more collectors to explore the above district and 

 try to clear up some of the difficult points. Very little has yet been 

 done, but until this region is well explored our knowledge of what 

 the Sierras contain will necessarily be limited.* 



*Most of these butterflies were named for me by Mr. J. J. Rivers.

With Plate xxiii. 

 BY T. S. BRANDEGEE. 



RuMFORDiA CONNATA. Perennial, herbaceous 1-2 m. high; 

 stems clustered, much branched near the top, glandular-pubescent: 

 leaves yi-iyi dm. long, ovate, acuminate, serrate, decurrent on the 

 petioles as a broad margin and connate into a cup often 1-2 cm. in 

 depth, more or less filled by the hirsute pubescence; nodes as long 

 or longer than the leaves: panicle compound: heads long-peduncu- 

 late; peduncles slender, naked: heads 4-5 cm. broad; outer involu- 

 cre foliaceous, deeply 5-8 lobed, its segments nearly equalling the 

 rays, two of them usually much broader than the others and 2- 

 toothed at apex; inner conduplicate about % the length of the out- 

 er, green and glandular on the back, acute, and three times the 

 length of the akene; receptacle convex, the paleae membranaceous, 

 obliquely obtuse, somewhat boat - shaped, loosely enclosing and 

 twice longer than the akenes: rays ? , numerous 15-18 mm. long,
