LEMONIAS I. 



YoiTNG Larva. — Length, .04 inch ; cyhndrical, thickest at 3, tapering pos- 

 terioi-lv. tlie doi'sum a httle arched, each segment rounded ; color yellow-green ; 

 from 3 to 12, two dorsal rows of broad, oval, flattened brown processes, from 

 each of which comes a pencil of five long, recurved, black hairs, one being 

 shorter than the rest ; along lower part of side, from 2 to 13, are three long and 

 depressed white hairs to each segment, and under them some fine and shorter 

 ones ; on 2, is a dark brown, oval, tumid process, and on the anterior half are 

 six long black hairs on either side tlie medio-dorsal line, all turned forward ; in 

 front of these is a fringe of long white hairs which fall over the head ; 13 is 

 brown at extremity, and the hairs extend back horizontall}^, or a little depressed ; 

 feet and pro-legs yellow-green ; head a little broader than 2, ol^ovoid, bilobed, 

 slightly pubescent ; color dark brown. (Fig. k.) The head is not retractile but 

 is partly covered by 2. 



The 3'oung larva is almost precisely like Nais at same stage, but is more green, 

 and the red stripe on side is wanting. 



Palmerii is common in New Mexico and Arizona, and probably in Southern 

 Utah. It was described in 1870, from a single male brought from Utah by Dr. 

 Palmer, and for a long time this remained unique in collections. But Messrs. 

 Neumoeiien. Doll, and Morrison have brouo;ht in laro-e numbers. 



Mr. Morrison writes : " I found L. Pahnerii at Fort Thomas, Arizona, in May ; 

 elevation 1,800 feet. It was flying only on Mesquit, both on the leaves and flow- 

 ers, more often on the latter. It flies very quickly, and when at rest generally 

 holds its wings perfectly flat, and sometimes will flutter them rapidly, but it 

 never holds them back to back, like Thecla. I found Palmerii also at Grant, 

 Ariz*., in June, — elevation 1,500 feet, — always on Mesquit, and witli the same 

 habits." 



I received from Mr. Doll, at Tucson, 26th May, 1881, a box containing about 

 fifty eggs of Palmerii, with twigs and leaves of Mesquit, on which they had 

 been laid. A few of the eggs had hatched, but the larvfe had apparently es- 

 caped. On 27th, I saw one come from its egg, from the depressed top, a round 

 hole being eaten out, just large enough to j^ermit egress. None of the shell 

 was consumed. I did not at the time know the plant, but supposed it to 

 be a species of Cassia, and therefore provided leaves of Cassia marilandica. 

 But the larvfB, some half dozen in number, all died, and I was able to learn 

 nothing of the subsequent stages. After this the larvae of L. Nais were found 

 to like leaves of wild plum, and probably Palmerii would have eaten the same. 



Lemonias is one of the genera in the family Erycinidaj, of which Mr. H. W. 

 Bates says, in the Linnnsan Society Journal, vol. ix., 1863 : " The Erycinidas are 

 well distinguished from all other butterflies, with the exception of the genus
