Named in honor of the collector, who has sent me this exciuisite 

 species among several oth(M' Tineina. It is somewhat on the order of 

 Ariatotelia eleganteUa Chaml)ers and fully as handsome.

Chambers's types of this species in Cambridge are identical with a 

 large bred series in U. S. National Museum, determined by Lord 

 Walsingham. The larv» live in the stems of Polygonum ocre^ 

 causing a slight swelling at the joints, and are found very commonly 

 in the vicinity of Washington. Frequently every joint of a plant con- 

 tains a larva. The species overwinters in the stems as larva?, and the 

 moths issue during May and June. It is of interest to note that the 

 peculiar shining color of this species is identical with that of another 

 polygonum feeding Tineid, Gelechia discooceliella Chambers. 



The superficial resemblance to the tsenlonella group of Europe has 

 induced Lord Walsingham, and subsequently Dr. Dietz, to place this 

 species in Aproxrema Durrant {Anacampsis auct.), but the venation 

 shows that it belongs to the present genus. 



This species has been bred in the insectary of L^, S. Department of 

 Agriculture under the nmiiber 3378. 



Under No. 4575 has been reared another large series of Aristotelia 

 from the roots of Ampelopsis quimpiefolia, received from Mr. G. 

 Barlow, Cadet, Missouri, and issued in March and April, 1890. 



These moths average a trifle larger than those bred from Polygonwa^ 



but I can not otherwise distinguish them, and am forced, at present at 



least, to place them und(»r this species in spite of the improbabilit}^ 



that one species should have ])oth food plants. Possibly some mistake
