AMERICAN LEPIDOPTERA. 425 



A Supplement to the 

 «■ DESCRIPTIONS OF AMERICAN LEPIDOPTERA." 



BY AUG. R. GROTE AND COLEMAN T. ROBINSON. 



[Under the above title five papers have been printed in these Trans- 

 actions. The untimely death of Mr. C. T. Robinson has prevented 

 the completion of a series, which was intended to include one hundred 

 figures of American Moths. Eighty-six figures had been published 

 at the time of Mr. Robinson's decease, illustrating five descriptioual 

 papers dating as follows : 



No. 1. Vol. i., pp. 1 — 29 with 2 plates and 25 figures, and dated 

 June, 1867. 



No. 2. Vol. i., pp. 171—192 with 1 plate, figs. 26 to 35. and dated 

 August, 1867. 



No. 3. Vol. i., pp. 323—360 with 2 plates, figs. 36 to 59, and dated 

 January, 1868. 



No. 4. Vol. ii., pp. 179 — 206 with 2 plates, figs. 60 to 76, and 

 dated September, 1868. 



No. 5. Vol. iii., pp. 176—182 with 1 plate, figs. 77 to 86, and 

 dated October, 1870. 



During the time in which these papers were being written we 

 visited the British Museum together and examined many of Mr. 

 Francis Walker's types of the new species of Moths described in the 

 British Museum Lists. A paper devoted to the changes in nomen- 

 clature proposed in consequence, has already appeared in these Trans- 

 actions, Vol. ii., pp. 67 — 88. 



The descriptioual part of a sixth paper of our series, the one 

 intended to bring the number of figures to one hundred, was partly 

 finished at Mr. Robinson's death, but many considerations will pre- 

 vent its being printed. This sixth paper, however, embodied a revi- 

 sion of the species previously described which is given here.

The species we have hitherto mentioned and illustrated in this 

 series of papers are here briefly enumerated in a systematic order and, 

 where it is found necessary, changes are made in the names originally 

 proposed. ,
