the brown spot at their posterior angle is more distinct ; the six orange 

 marginal spots of the secondaries, are brighter. 



I deem it probable that we still have at least two species confounded 

 in comma, — the determination of which will require close observation, 

 and such particular larval descriptions as I have endeavored to give 

 above. 



The female has the wings less emarginated than the male. With the 

 two side by side, a casual glance at the broad and short tail of the 

 secondaries of the former, and the longer and more slender tail of the 

 latter, will serve to designate the sexes. This difference is observable, 

 though to a less extent, iu the other species of this genus. Another 

 obvious sexual characteristic of Grrapta, is, the long hairs which clothe 

 the anterior pair of legs of the male. 



I have captured this butttn-Jiy &n.v\\ev than any other species, — flitting 

 about in the warm sunlight of a spring-like day, on the 2nd of March. 

 Although but slightly worn, it had undoubtedly been drawn out from 

 its winter quarters. 



The first brood makes its appearance in June. Its larva will proba- 

 bly be found on the Elm, during the preceding month. Of the second 

 brood, from the Hop, I have had them from chrysalis, from the 25th 

 of August to the 5th of September. 



GrRAPTA PAUNUS, Edwards. 



This species is of much more rare occurrence in this locality than 

 the preceding Among the Adirondack Mountains of this State, near 

 Raquette Lake, in the mouth of August, I once met with a large gath- 

 ering of them, upon a small spot of moist earth. Usually extremely 

 shy as are all the Grraptas, my approach startled only a few of their 

 number, which, after a short circuit, returned to their repast. I expe- 

 rienced not the least difficulty in capturing twenty or more by hand, 

 although another collector had preceded me — a large toad {Bu/o ame- 

 ricaauii) — whom I found holding a central position in the group, and 

 earnestly engaged in lapping up with his broad tongue, one after an- 

 other of the company, with the greatest dexterity, seldom missing an 

 attempt. After watching for some minutes the novel performance, I 

 left him still gorging himself upon what I should judge to be unusual 

 Batrachian diet.
