JAPANESE LEPIDOPTERA. 71 



Description of new species or Japanese Heterocera. 



BY REV. W. J. HOLLAND, D.D. PH.D. 



It was my privilege, in the year 1887, to be invited by my friend, 

 Prof. D. P. Todd, of Amherst College, to accompany the expedition 

 sent by the United States Navy Department and the National 

 Academy of Science, to Japan for the purpose of observing the total 

 eclipse of the sun of that year. As the naturalist of the party I 

 was accorded much courtesy and was enabled to prosecute somewhat 

 widely investigations into the botany and zoology of the islands. 

 The brief space of four months, during which I labored upon Japa- 

 nese soil, was, however, all too short for satisfactory work, and I 

 I'egret greatly that I was not able to devote a much longer time to 

 study and research in this most interesting field. Nevertheless the 

 i-esults achieved were not altogether unsatisfactory, and I have the 

 pleasure in the accompanying paper of presenting to the attention 

 of the scientific world descriptions of a few species of Macrolepid- 

 optera, which, so far as I am aware, have not yet been described. I 

 confine myself in this paper mainly to species which, having resolved 

 to name in honor of persons who were members of the U. S. Eclijjse 

 Expedition, or who rendered us assistance, I wish, therefore, to ap- 

 propriate before some other entomologist shall have attached to them 

 a designation. 



HETEROCERA. 



SPHINGES L. 



Family SPHINGID^ Boisd. 



Subfamily Ch^rocampin^e Butler. 



Genus AC'OSMERYX Boisd. 



1. A. lyeuobu u. sp. 



Upperside. — Head, thorax aud abdomen ferruginous, the head and thorax 

 being redder than the abdomen. A light mouse gray dorsal line runs from the 

 crest to the anal extremity of the abdomen, and a line of the same color passes 

 just over the eyes along the lower edge of the tegulse. The first and second 

 segments of the abdomen are marked with black spots, the first of which is 

 preceded by a tuft of mouse-gray hairs; the sides of the abdomen are lighter in 

 color than the back. The auteuuse are light yellow ; the palpi are a shade paler 

 than the head and grayish in color. Primaries : the general color of the prima- 

 ries is gray with a lilac cast, inclining to ferruginous at the base and the costa.
