 costa at base. Hind wing mouse -gray. 13 mm.

2. LASPEYRESIA ILiibnei- 



(Grapholitha Rebel, etc.; Enarmonia, Fernald, etc.; Ephippiphora, of 



the earlier writers) 



Palpus with second joint merely rough scaled below (fig. 272), the vestiture 

 not concealing the third joint, which is usually about a third as long as the 

 second, and scaled. Thorax and fore wing like Hemimene; hind wing with 

 R and M! more approximate at base (fig. 248), usually somewhat sinuous, and 

 diverging abruptly about a third way to margin. M L , strongly curved but well' 

 separated from M 3 which is connate or stalked with CUj. No sexual modifications, 

 except for some dense scaling on the hind wing of L. pyrlcolana. 



The species are numerous and close and the following key may not be always 

 successful. 



Enarmonia dana Kearfott is a Hemimene; L. lautana is strongly aberrant, 

 and represents a new subgemis Sereda Heinrich: L. shamana. is a Hendecaneura. 

 Aside from the slight difference in venation and palpi, the genus may be distin- 

 guished from Hemimene by the absence of terminal dots just back of the outer 

 margin, below the notch; usually there are no terminal dots at all, but in L. lautana 

 they are present exactly on the margin of the wing membrane, and are strongest 

 on the apical part of the wing. 



Key to the species 



1. Two terminal dots at apex noticeably larger than the others 1. lautana. 



1. A single larger terminal dot at apex, or none. 

 2. Hind wing half or more pure white. 

 3. Fore wing blackish. 



4. Fore wing with a white crescent at middle of inner margin. 



21. albimaculana. 

 4. Fore wing with only n faint gray crescent at middle of inner margin. 



10. eclipsana. 



3. Fore wing gray 18. multilineana. 



2. Hind wing fuscous to blackish: sometimes with more ">r less of base dirty 



white. 

 3. Ground of fore wing dull white. 



4. Outer half contrasting dark, largely blue 20. flctcherana. 



4. Base of inner margin and outer third spotted with blackish. 



22. gallcBsaliciana. 

 3. Ground of fore wing blackish. 



4. Two strongly irregular silver-white striae clear across the wing. .16. rana. 

 4. A contrasting white crescent or group of striae on middle of inner margin, 

 reaching up about to middle of Aving, but entirely separate from 

 the costal stria. 

 5. Dorsal white extended in along inner margin to base. 



(Pammene felicitana.)
