REPORT OF THE STATE ENTOMOLOGIST 1903 107 



adult accompanies it though a specimen of O. bilineatum 

 Say was in close proximity to the cocoon. There is apparently 

 nothing in that collection which can be used in the identification 

 of this species. A specimen in the United States national collec- 

 tion has been labeled by Dr Ashmead as Eremotylus gla- 

 bra t u s Say. It corresponds very closely with the description 

 of E r e m . a r c t i a e . The most apparent differences are in 

 its small size and the comparatively slender marginal or radial 

 nervure with no distinct angle or tooth near the stigma, a 

 character which is usually well marked in both E r e m . mac- 

 r u r u s Linn, and Erem. arctiae. 



This species has undoubtedly been erroneously identified in a 

 number of collections and the following references, except that of 

 its original describer, in all probability relate to something else. 

 Prof. G. C. Davis some years ago informed me that but one in- 

 dividual of this species was known to be in existence and that was 

 in his possession. Say's original description of this insect is 

 reproduced below : 



Honey yellow; a glabrous spot in the large cubital cellule. 



Body dull honey yellow; head bright yellow; antennae, mouth 

 and stemmata honey -yellow ; eyes blackish; wings, first cubital 

 cellule beyond its middle with a longitudinally oval glabrous 

 space, but destitute of any opaque spot ; metathorax transversely 

 wrinkled near the petiole of the abdomen. 



Length about I inch.
