This species is the type of the genus and the more specialized of the 

 two species. It has veins 7 and 8 in the forewings coincident. 



Chambers is himself responsible for placing his aphroditeUa as a 

 synonym of irridijpennella., which the description indicates is the case. 

 He committed, however, a clerical mistake in doing it. He wrote :^ 



Strobisia venustella I am now satisfied is a synonym of S. irridlpennella Clemens. 

 Because of the presence of several brilliant blue spots on the wings of my specimens 

 I not mentioned in Dr. Clemens' description, I was led to believe that they belonged 

 to a different species. But the individuals vary in this respect. 



I There can be no question but that vemi.stella is a mistake for aj>hro- 

 1 diteeUa, the description of which onl}^ can be applied to irridi/pennelJa. 

 \ This is also demonstrated by Chambers afterwards in his " Index," ^ 

 ! where he placed his species right, a2)hroditedla as synonjnn of irridi- 

 /peninella and venuHtelJa as synonym of the following species, einhle- 

 I mella Clemens. 



. On account of the same defects in Clemens' description, which misled 

 I Chambers. Frey described \a^ pTOserpinella^ which undou))tedly is the 

 j same as ii'ridljjennella. the description agreeing in every particular. 

 ; Although this species is very abundant in the vicinit}" of Washing- 

 ton, and though I have given special attention to it for some years, its 

 larval history is as yet entirely unknown, and furnishes a worthy sub- 

 ject for study for any student who has an opportunity to work it out. 

 The larva will, I believe, l)e found to ])e a stem borer.

Strohina venustella Chambers, Can. Ent., IV., 1872, p. 90. 



This well-described species differs generically from the tj^pe only by 

 having vein 8 in forewings present, out of vein 7. A specimen deter- 

 mined by Lord Walsmgham and by the writer are in the U. S. National 

 Museum. 



It is not nearl}^ as common in the localities around Washington as 

 I the preceding species.
