June, I902.] BUSCK : NORTH AMERICAN TlXEINA. 97 



This species was described from a single specimen in poor con- 

 dition in the collection of the Philadelphia Academy of Nat. Sci- 

 ences, which I have examined. 



Mr. J. H. Durrant writes me that Lord Walsingham now has two 

 specimens in his collection from North Carolina (Morrison). 



In the U. S. National Museum is one good specimen, collected by 

 Mr. F. C. Pratt at Travilah, Md., in July. 



Plutella (?) multimaculella Chambers. (Plate XII, Fig. S.) 



Gelechi I :" multiinactilella Chambers, Bull. U. S. Geo. Surv., IV, 89, 1S78 ; 

 Hagen, Papilio, IV, 99, 1884; Riley, Smith List, Lep. Bor. Am., No. 5414, 1891. 



This insect is not a Plutella and is only placed temporarily in this 

 genus. It will form a new genus in the Yponomeutidse, but I prefer 

 to obtain more ample material before establishing such. 



My object in treating this and some of the other species men- 

 tioned in this paper, at this time is merely to get rid of them from the 

 Gelechiidffi and place them at least in the family to which they belong, 

 until special study of that family can dispose of them finally. 



This in order that they can be included in Dr. Dyar's forth- 

 coming Catalogue of North American Lepidoptera. 



Gelechia ? niultimacitlella Chambers, has the following venation : 

 Fore wings ii veins; one of the dorsal veins (5?) absent; 8 and 9 

 out of 7, 7 to costa. 



Hind wings 7 veins, 4 absent 5 and 6 stalked, 7 parallel with 6. 



The labial palpi are smooth, both joints broad and flattened, ter- 

 minal joint not pointed, shorter than second joint and erect. 



Mompha sexnotella Chambers. (Plate XII, Fig. 7.) 



Gelechia sexnotella Chambers, Bull. U. S. Geol. Surv., IV, 88, 1878; Hagen, 

 Papilio, IV, 99, 1884; Riley, Smith, List Lep. Bor. Am., No. 5482, 1891. 



The unique type of this species is found in good condition and 

 with Chambers' handwritten label on the pin in the Cambridge 

 Museum of Comparative Zoology, where I studied it carefully in 1900. 



It agrees well with Chambers' specific description, but it is an 

 Elachistid and may provisionally at least be included in Mompha 

 Hubner, though it differs from Meyrick's definition of this genus in 

 having veins 6 and 7 of hind wings stalked. 



In the National Museum is a series of this species, bred from galls 

 on Trichostema dicholomiim from Georgiana, Florida. Similar galls
