I found this species while collecting larva of Lycena exilis, 
which abound on the same food- plant. I find, however, that 
Prof. Townsend actually discovered the insect, specimens 
obtained by him being in the collection of the New Mexico 
Experiment Station. 
I name this species after my wife, who died Sept. 14, 1893. 
The United-States species of Orthezia are at present im- 
perfectly known. Walker described O. americana, and, 
although his description was quite imperfect, it’ is generally 
admitted that he had before hima species found in the North- 
eastern States on various herbaceous plants. Prof. Comstock 
(1881) figured and redescribed Walker’s s species, which until 
lately remained the only known representative of its genus 
in the country. 
In 1888 Mr. Ashmead described O. Edwardsit from Cali- 
fornia, but he knew only the male, and the female still awaits 
discovery. In 1891 Mr. Douglas published his O. occ¢dentalis, 
based on specimens found by “the present writer in ants’ nests 
in Colorado. Of this the adult male is undescribed. 
O. Anne, which is easily distinguished by structure and 
habitat from the above, is thus the fourth Orthezta detected 
in the United States. A fifth species, O. insignis, Douglas, 
has lately been found by Mr. R. H. Pettit in hothouses in 
New York State ; but this is properly a member of the West- 
Indian and Mexican faunas. The most northern locality yet 
known for it out of hothouses is Guanajuato, Mexico, whence 
I have received specimens from Dr. A. Duges.
