service to tlic student wlio may under- 

 take the task I abandon. It is only in 

 the first two subfamilies that genera and 

 species are considered, and I have there- 

 fore adopted for this collection of frag- 

 ments the title given above. 



Subfamily EUPLOEINAE. 



Butterfly: Palpi stout, tufted with 

 hairs. Antennae naked, arcuate, the 

 club drooping, tolerably well marked. 

 Fore legs of both sexes excessively atro- 

 phied, short and nearly naked. Fore 

 wings long but ample ; none of the nerv- 

 ures swollen at the base ; internal nervure 

 present ; discal cell of hind wings long 



and closed by an interrupted vein ; costal 

 nervure terminating at middle of costal 

 border. Abdomen unusually long and 

 slender, the males with anal tufts of 

 protrusile hairs. Colors of wings gener- 

 ally massive and generally very similar 

 above and beneath. Egg: Sugarloaf 

 shaped, considerably higher than broad, 

 truncate and scarcely rounded at base, 

 with slight vertical ribs and small cells 

 at the outer borders of the crown. Cat- 

 erpillar at birth: Head no larger than 

 segments following. Body cylindrical, 

 uniform, unicolorous; ranged append- 

 ages simple tapering hairs usually shorter 

 than the segments.
