half of secondaries and ending in an oblique streak up tlie inner margin ; 

 each spot edged black on outer side, and on primaries, in the median 

 interspaces, there is more or less fulvous outside the black ; on secondaries 

 is a large sjjot on the margin behind lower median nervule, made by blue- 

 white scales on the brown ground ; and in the next interspaces are three 

 deep red fulvous spots, diminishing gradually in size, the outer one some- 

 times obsolete, the largest with a black patch on its marginal side ; anal 

 angle black, overlaid on inner margin by white and a red streak ; the inner 

 of the two lines is extra-discal, somewhat irregular, especially on second- 

 aries, and joins the other at the lower median nervule of secondaries, then 

 makes an angle in sub-median interspace, and ends in a streak up inner 

 margin : in cell of each wing two parallel abbreviated white streaks or bars. 



Female — Expands 1.7 inch. 



Upper side as in the male, except the stigma: the tails measure .26 

 and .12 inch respectively : under side as in the male. 



From 3 (J I !^ taken by Dr. ^\'m. AVittfeld, at Indian River, Florida, 

 1883. This observer, in the past three years, has done more to elucidate 

 the biological history of the Lepidoptera of Florida, than any one who 

 has preceded him in that section, and he has discovered a remarkable 

 number of new si)ecies of butterflies especially, and has introduced to the 

 N. Am. tauna many other species both of butterflies and sphinges, which 

 though previously described, had not been seen in the U. States. I take 

 pleasure in naming this fine Thecia for Dr. A\'ittfeld. 



The examples were sent me labelled Favoiiius. a species quite distinct 

 from the present, which in several respects is near to Calanus. It differs 

 from Cahinus by the greater size, the very long tails, and in the inner of 

 the two transverse lines beneath, which is single, whereas in Cahinus this 

 line is double, or chain-shaped : the parallel ?jars in the cells are like those 

 of Calanus ; also like Cry sal us, and such bars are found in no other of 

 the American species. 



IMPORl'ANT TO ENTOMOLOGISTS. 



In accordance with a resolution passed at a meeting of the Entomolo- 

 gists in attendance at the Montreal Meeting of the American Association 

 for the Advancement of Science, in August, 1882, authorizing me to call 

 and '• to provide for similar meetings for Entomological discussions at the
