REVISION OF SPECIES OF THE GENUS AGROTIS. 29 



of the descriptions most o1)vioiisly ooiifoiiiid two or more species, aiul 

 again there is very little doubt but that every one of the species has 

 been described more than ouce. Still with the descriptions alone, I 

 would have made out fairly well, but I was again thoroughly upset by 

 the remarkable identifications made by Mr. Grote, and the unreliability 

 of the word " tyi)e"on some of the labels, insects bearing them not 

 agreeing at all with the descrii)tion. 



I found the exsertistigma of Mr. Tepper's collection to equal the oh- 

 .5eriYf/>///.s' of the Neumoegen collection, wiiile the exHcrthti(jnm of the 

 Neumoegen collection was dillerent from that of theTei)per collection, 

 and neither of them was like the type in Mr. Griefs collection. The 

 dist'oidnlis of Mr. ITulst's collection is the observabilis of the Gra'f (;ol- 

 lection, but not of the Neumoegen collection, and the type in Mr. Ed- 

 wards's collection is entirely' different from any I have seen so named. 

 So also the faciiUi of the Neumoegen collection is different from the 

 same species in the Edwards collection. 



Some of the absolute types were inaccessible to me, and under the 

 circumstances I have named all the species that I could not positively 

 identify, and have given all of Mr. Grote's original descriptions for 

 comparison. I fully expect that all the names here given by me will 

 fall into the synonymy, but they will at least have served their purpose 

 of positively separating the forms, and at some future time when com- 

 parisons can be made in jNIr. Grote's collection in the British Museum 

 the rectification of the synonj'my can be easily noted here. 



The species of the group divide readily into two sections, according 

 as the collar is or is not black tii)i)C'd. 



In the series with the collar black tipped, exsertistujma is distin- 

 guished by the pale luteous gray color, the elongate primaries, and the 

 dei)ressed form. 



Formalh is smaller, much more robust, shorter winged, and dark red 

 brown or pur[)lish in color. To this 1 refer insularis positively from 

 the ty[)e and the descri[)tion. Einarginnta is almost (jertainly a form of 

 this species without the gray shaded costa. I did not lind the species 

 in Mr. Edwards's collection, from which it was described. 



Carisnima llarv. was referred by its describer as allie<l to formnlift, 

 and the descri[)tion is com[)arative and entirely insullicient to identify 

 the species. Mr. Grote broke up Dr. Harvey's association of the spe- 

 cies, and placed it with intrita and rava, so that the description be- 

 comes worse than useless. 



Binominalis is bright red, the collar is slightly produced at middle, 

 the tufts are very distinct, ami the apices of primaries are more evident 

 than in either of the preceding forms. 



Ohservahilis is a species that I have not been able to identify. Mr. 

 Grote's identitications in no case agree with his description of this spe- 

 cies, and I have seen no specimens to agree with it. The color is dark 

 blackish brown, the reniform dusky, and the terminal space pale, oliva-
