one did have small black spots under the band. Comparintr with 

 Eurydice, the two are very much alike in form, color, surface, but the 

 larva of Eurydice has the red stripe macular, and there are peculiar 

 rounded black knobs about the body which are not found in the other 

 Coliads named. The ^^^^"^ and chrysalids of all these species are after 

 one pattern. 



I offered these larvct red clover, that being the usual food j)lant of 

 P/ii/odice, but they at all stages refused this. White clover they eat 

 readily. The same thing occurred with larvse of C. Hagenii from 

 Colorado. Its food plant was an Astragalus also, and red clover it 

 utterly refused to touch. I lost many of the Harfordii larvae all 

 through the stages to pupation, either from change of food or change 

 of climate, so that I got but two butterflies at last, i (? i 9 • The 

 former came out 8th August, the other on 6th August. Both were 

 bright canary-yellow. The female has an even border quite to inner 

 angles; no black at base; a slight trace only of submarginal spots, 

 and very little dusting on under side. That is, it is of same type 

 with H. Edwards' male Harfordii except as to color, which is that as- 

 cribed to Barbara. The male is of the Harfordii type, only with color 

 of Barbara. 



In a letter received from Mr. Wright, dated 26th Dec, 1883, he 

 speaks of finding larvae of Harfordii of all sizes up to mature, and, as 

 he says, "this proves that they breed here all winter." 



A NEW SPECIES OF NYSTALEA. 



By a. R. Grote. 



Nystalea Indiana, n. sp. — $ . Antennae shordy pectinate on basal 

 half, simple to tips. W'ings long; abdomen exceeding hind wings. 

 Head and collar discolorous ochrey. Fore wings dirty gray, with up- 

 right faint brown lines. Two brown costal spots at middle and two 

 beneath them on median vein. Reniform, tv\^o brown points connected 

 by a pale shade. Fringe dotted. Hind wings with whitish pellucid 

 base and black borders. Expanse 42 mil. Indian Ri\er. Florida. 



This has no apical pale patch, like Conchifera. 



This tropical genus has not been previously found in the United 

 States. There are hardly any but West Indian forms found in South- 

 ern Florida, and to work them up properly it needs a full West Indian 

 collection. It is evident that for sometime the synonymy of the species 

 must be uncertain and there is no other way than to describe our 

 species in cases of doubt. Ultimately the collections described by Mr. 

 Walker from the West Indies will ha\e to be overhauled and compared 

 with Floridian collections.
