considered congeneric with E. Poeyi Grote. The specimen now sent has 

 an undivided frenulum and is unquestionably a male. It does not show, 

 however, the aberrant wing structure of Euscirrhopterus. It might be 

 referred to Eudryas but for the peculiar frontai structure. Instead of a 

 tubercle, a wide plate extends forwards from the clypeus, with a lip-shaped 

 outer margin, which is peculiar. I therefore make it the type of the genus 

 Copidryas. The thorax is hairy, grayish black ; two white lines run from 

 the palpal tips above the eyes to the base of the head. The ordinary 

 lines are expressed by metallic scales, and the black edged sub-equal 

 stigmata are filled with similar scales. The female type of the species is 

 not accessible to me and its description varies, as above noted, from my 

 present male. It was, I recollect, not in very good condition ; and it has 

 been figured by Glover (Plate 85, fig. 34). From this figure my male 

 differs by the absence of the shallow white median sinus, and white 

 internal annuli to the stigmata, as well as by the narrow black band on 

 the hind wings (even on its inner edge), and less brownish, more grayish 

 black primaries ; the orbicular is also more elongate. The yellow abdo- 

 men is black at anus and tufted with black scales at base. There is 

 besides a mesial line of black scales on the dorsum. The eyes are 

 naked. On the whole, I am inclined to consider this form as the $ of 

 C. Gloveri ; more material of both sexes and a comparison with the type 

 are needed to make the matter certain. It is not unreasonable to expect 

 some sexual differences, in coloring at least, in this group. 



Larv/E of Thyreus .Abbotii. — In response to Mr. Whitney's article 

 with regard to the supposed sexual distinction in color of the larvae of 

 this species (Can. Ent., 8, 75), I can confirm it from my observations 

 made in breeding larvae of both colors in Brooklyn, L. I. I have never 

 regarded the color as a sexual character and in my Sphingidae of Cuba 

 (Proc. Ent. Soc: Phil., 1865) I state distinctly that " the larvae of Thyreus 

 Abbotii and certain species of the genus Philampelus Harris, possess a 

 tint of brown or green indifferently at maturity." I give, the same fact 

 with regard to Eacles. I regret that I cannot now refer more particularly 

 to observations which were fresh in my mind when I made the above 

 quoted statement. — A. R. Grote.
