Endropia homuraria G. and R. Dr. Packard places this as a syno- 

 nym o^ E. dtiaria Guen, But Mr. Grote, (Can. Ent. IX, 89 and Papilio 

 II, 100), with considerable feeling and logic, protests against this dis- 

 position of his species. Dr. Packard had Mr. Grote's type, and his 

 opinion, with such opportunity of comparison, ought to be final. Certain 

 it is if it be not E. duaria, it is E. hypochraria H. Sch. The description 

 seems to be of the reddish form of the latter. But Dr. Packard's opinion 

 will have to govern us till we have more light. What has become of Mr. 

 Grote's type I do not know. It is not in the Central Park Collection 

 where Mr, Grote thought it might be. E. duaria Guen. differs very much 

 in appearance, the wings being rectangular and very rounded in some 

 male specimens, and very pointed, falcate and angulated in some females. 



Endropia amcenaria Guen. E. arefactaria G. and R. is a synonym 

 of this species. If one take Mr. Grote's description of his species, 

 and compare it with a specimen oi E. amcenaria he will not doubt their 

 identity. Dr. Packard had Mr. Grote's type, and his description and 

 figure in his Geometrid Moths are from this type specimen. I speak of 

 this as Mr. Grote has in later years claimed that his species and that of 

 Guenee were not identical, although he admits his may be a variety. In 

 looking over Mr. Neumoegen's collection, which in 1882 Mr. Grote 

 studied, I find several specimens with label '^Endropia arefaciaria Gr." 

 in Mr. Grote's handwriting. It may be Mr. Grote has identified this 

 same form in other collections as his species. But this is not E. ama^naria 

 at all, but a slight variation from the type form of E. viadiisaria Wlk., 

 not sufficiently distinct however to deserve a varietal name 



Endropia helveolaria Hulst. In Mr. Neumoegen's collection I find 

 2 (^(^ and I 9 of this species, each with label in Mr. Grote's handwriting 

 "Ljchnosea aulularia Gr. Type."' I cannot find the published descrip- 

 tion of either the genus or the species. The specific name, if it were 

 published at the time of Mr. Grote's study of Mr. Neumoegen's collec- 

 tion (1882) would be a synonym. What the fate of the genus would be 

 I cannot say, for the insect is likely not an Endropia. 



Ellopia fervidaria Hiibn. Dr. Packard includes under this species 

 E. fiscellaria Guen., E. Jlagitaria Guen., and as well the form called by 

 me E. so7?miaria. I have before me of what I esteem the true E. /ervid- 

 ar/a 39 specimens, oi E. fiscellaria ^o, o^ E. somniaria ^. E.flagitaria 

 will not stand as a distinct species, but the other three seem to me not to 

 intergrade, and to be good species. In E. fiscellaria Guen., there is very 

 great variation in the width of the cross lines. In one specimen from
