Four snlispecii's. 



A very small s}ieciiiien, said to be from Texas, represents perhaps a fifth 

 geographical form. The subspecies are not different in the structure of the 

 sexual organs of the c?. The ? genital iuuiature has 011I3' been examined of 

 ckersis ('hersis.

S. Darker than orcoduphnc and r/irrsis, but ground colour ])nrer whitish grey, 

 without clayish shade ; the costal nnirkings and the; obli(jue subbasal postcellnlar 

 double line of the forewing obviously more distinct, as is also the dark shade at 

 the proximal side of the black submarginal line ; white fringe-spots very sharply 

 defined ; black discal band of hindwing broad, strongly angled externally at SM- ; 

 basal half of cell of forewing below brownish black. The figure in the Bioloqia is 

 too brown. 



? . Not known. 



Hab. Mexico. 



In the Tring Museum 1 S from " Mexico," type. 



Mr. Druce was misled in the identification of this insect by Hy. Edwards, who 

 determined the Durango specimen as perelegans. 



b. II. ckersis pallescens subsp. nov. 



It is one of the objects of the systematist to elucidate facts, not to conceal 

 them. The differences between the subspecies of //. chersis are slight, but they are 

 there and must be registered. 



c??. As large as the average 11. ch. chersis \ of tlie same white-grey ground 

 colour as me.ricanus, with which it agrees also in the sliarply defined white fringe- 

 spots. A perfect transition from mexicanus to chersis. 



Hab. Arizona ; Colorado.

c? ?. Difi'ers from 1/. chersis chersis in its inferior si/,e, in the- black discal hand

We have received a photograph of the type of oreoda phuc from Hy. Edwards's 

 collection, through the kindness of Mr. Beuteumiiller.
