NEW SPECIES AND NOTES ON STRUCTURE OF MOTHS 



AND GENERA. 



BY A. R. GROTE, A. M. 

 (Continued from Vol. xv., Paye 13.) 



Catocala Coelebs Gr. 



The fore wings are />/ad' with a grayish white subterminal shade. A 

 strongly marked variety of Badia with the fore wings brown, was mistaken 

 for Coelebs by Mr. Strecker, and was the occasion of its reference to 

 Badia. But a sight of many specimens leads me to believe that the true 

 C. Coelebs, with black fore wings, grades into Badia, and is only to be 

 regarded as a variety of it. But this could not have been predicated of 

 the type. The two extremes are exceedingly distinct and different 

 looking. 



EXENTERELLA GrOtC. 



I propose this generic term for Exentera Gr., preoccupied in Insecta. 

 Now that we have Mr. Scudder's work on genera, there will be more cer- 

 tainty about generic names. I notice that Rhododipsa is not included in 

 Mr. Scudder's list. In speaking of the omissions in my review of it, I did 

 not intend that any idea of purposed favoritism should be conveyed by my 

 words. I merely regretted that some authors should have been so fully 

 and others so sparingly represented. Had the proof of my paper been 

 sent to me, I think I should have changed the wording to a simple expres- 

 sion of this regret. 



Hemileuca Walk. 



Since examining the species carefully, as far as they are accessible, the 

 following modification of my arrangement in the " New Check List," p. 

 20. is proposed :
