tion, but may readily be distinguished from L. acrcea, not merely by its 

 smaller size and the absence of markings, which alone in such genera as 

 this would scarcely warrant its separation under a specific name, but by 

 the color of the posterior wings, which are totally different from the well 

 known L. acrcea. It may not be uninteresting to add that I have in my 

 collection a £ exactly corresponding to the foregoing description, which I 

 received from Costa Rica through Dr. Van Patten. This gentleman's col- 

 lection was made in the table lands of the interior. I have also, from the 

 same locality, a large notodontid (?), likewise identical with a specimen 

 received from Arizona ! When it is remembered that I am as yet acquainted 

 with only five species of Bombi/cina from the district of Arizona and its 

 vicinity, it is somewhat remarkable that two of these should be represented 

 in a locality so widely removed as Costa Rica, and we may naturally look 

 for many striking additions to our list of insects as we become more familiar 

 with this as yet almost unknown country.
