262 COLEMAN T. ROBINSON, 



is Mr. Wilkinson's British Tortrices, and his generic diagnoses are so 

 peculiarly written, his tables of genera founded on a fanciful compari- 

 son of the length of the middle joint of the labial palpi with the api- 

 cal joint, that the location of a specimen is very troublesome and diffi- 

 cult. At some subsequent day I will review what I have done in this 

 group, as soon as I can obtain types of European genera and thus cor- 

 rect the numerous errors I have doubtless committed by describing new 

 generic groups, when genera have been already created into which they 

 could have been received, and of which I have no knowledge." These 

 were among the last words written by Dr. Clemens on any entomologi- 

 cal subject. His death in the prime of life, two years afterwards, de_ 

 prived us forever of one of the most thorough and intelligent students 

 of nature America has produced. 



A correspondence was commenced with Dr. Clemens shortly before 

 his death, the object of which was to cooperate with him in carrying 

 out the intention mentioned in the paragraph quoted above, and to il- 

 lustrate by plates and more detailed descriptions, the s^pecies discovered 

 in the mean time. A library of important works on the subject has 

 been accumulated as well as lange collections of European and Ameri- 

 can specimens. I now, with much diffidence, undertake the task alone, 

 hoping thereby to call the attention of abler systematists to the subject. 

 Leaving the full discussion of generic values and other matters of clas- 

 sifications until a future period, I shall endeavor to illustrate the spe- 

 cies thus flir obsei-ved. 



Messrs Francis G. Sanborn and Dr. A. S. Packard Jr. have assisted 



me materially by placing their collections in my hands for study and 



comparison.

 Palpi, head and thorax, dark reddish-brown. Antennae reddish- 

 brown. Anterior wings cinnamon-brown, with a basal patch, central 

 fascia and sub-apical costal spot dark reddish-brown and partially limi- 

 ted by slightly darker brown lines. The paler portions of the wing are 

 irregularly striated with reddish-brown lines, three of which, origina- 

 ting in the costal spot, and respectively just before, in and above the 

 internal angle. Fringes dark brown apically becoming paler below.
