thatch or under bark or, as in the case of some Depressaria, in notifies, 

 thereby occasionally causing unnecessary alarm when they appear in 

 numbers at the approach of warm weather. 



Several additional undeseribed species are represented in the 

 National Museum and very many species of the family will yet be 

 discovered when the fauna is better worked up. 



The writer had intended to make the present paper monographic 

 and to have included redescriptions of all the species as well as 

 descriptions of these additional species; but other pressing matters 

 intervened and would have postponed the work for at least another 

 year. It was not deemed advisable to withhold the generic rear- 

 rangement, and to this such descriptions of new species as were on 

 hand have been added. 



Fuller treatment of the family and figures of the generic characters 

 I hope to publish in a not-far-distant future. 



I am under much obligation to my learned friend, Mr. Edward 

 Meyrick, of England, whose intimate knowledge of this family all 

 over the world I have felt it my pleasant duty to consult freely, and 

 who has untiringly responded in his usual liberal manner; also to 

 Lord Walsingham and Mr. J. Hartley Durrant am I indebted for 

 various helpful notes. 



The genus Chambersia Riley, (Blepharocera Chambers, not Blan- 

 chard), which is included in the CEcophorida 1 in Doctor Dyar's List, 

 is as yet unknown to me, and it is not possible from Chambers's de- 

 scription and figure definitely to place the genus before the species 

 is rediscovered. I have omitted it from the present paper. 



The genus Endrosis Hiibner, which was placed in the family 

 Elachistidae in Doctor Dyar's List, following Meyrick's Handbook, 

 and which Lord Walsingham and Rebel have included in the Rlasto- 

 basidse, is in my judgment closely related to B orkhausenia Hiibner, 

 and is therefore included in this paper. 



The American genera may be recognized by the following table: 



1. Forewings with vein 7 to termen ..' 



Forewings with vein 7 to costa or apex 8 



2. Second joint of labial palpi straight, porrected ;?. Pleurota. 



Second joint of labial palpi curved ? 



3. Forewings with vein 9 out of 7 /. Martyringa. 



Forewings with vein 9 separate .'/ 



4. Labial palpi with long tuft on second joint 5 



Labial palpi smooth or nearly so 6 



5. Hindwings with vein 5 nearest .;. Eumeyrickia. 



Hindwings with vein 5 nearest 1 [?] .). Eido. 



(J. Veins i! and :{ in forewings approximate 7. Psilocorsis. 



Veins 1! and .". in forewings remote 7 



7. Hindwings with 6 and 7 diverging toward the tip 5. Gerdana. 



Hindwings with 6 and 7 parallel throughout 6. Cryptolechia. 



8. Abdomen flattened !)
