4 AMERICAN LEPIDOPTERA. 



For further consideration of the genera and species of this 

 subfamily I refer the student to my paper entitled " On 

 Pigritia Clem.,"* but I wish to make here a correction. An 

 examination of the type of Pigritia ochrocomella in the col- 

 lection of the American Entomological Society at the Acad- 

 emy of Natural Sciences of Philadelphia, subsequent to the 

 publication of my paper, proved this to be identical with my 

 pallidotinctella, type of Epigritia Dietz, also that heide- 

 mannella is only a variety of ochrocomella. What had been 

 recognized and described by me as ochrocomella — determined 

 as such by Lord Walsingham — will hereafter be known as 

 erratella. Of the twenty-nine species enumerated in Dr. 

 Dyar's list, one will be reduced to a variety. 



Subfamily BLASTOBASES. 



Labial palpi always strongly developed, long, and gener- 

 ally recurved. Veins 4 -f- 5 of forewing free. Hindwings 

 with eight, more rarely (Blaslobasis, Zenodochhcm) with seven 

 veins. 



Dr. Dyar's list contains twenty-two species of this sub- 

 family. Of these, Blastobasis subtractella Walker is a Gele- 

 chid ; Holcocera quisquiliella Ze\l. I regard as a variety of 

 chalcofrontella Clem. ; Hoi. nubilielta Zell. is identical with 

 Gelechia glandulella Riley (type of Valentinia Wish.) ; Hole, 

 friangularisella Ch. is Hoi. sciaphilella Zell. ; Hoi. fusco- 

 pulvella Ch., no description known, leaving thus seventeen 

 species and one variety ; Lord Walsinghamf in his paper 

 described fourteen new species. Four of these, however 

 (Hj'PaloPa episcia, conia, fasciata and orites) , belong to the 

 GEcophoridse, and have been referred by Mr. A. BusckJ to 

 the genus Borkeuhaiisia Hub. To the remaining ten have 

 to be added two of Chambers' species brought to our notice 

 by his lordship and omitted by Dr. Dyar in his list. This 

 then brings the number of species heretofore described to 

 twenty-nine and one variety. To these I have to add thirty-
