Mr. T. D. A. Coc.kerell on 



I found this species while collecting larvffi of Lyccena exilis, 

 which abound on the same food-plant. T 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 0. americana, and, 

 although his description was quite imperfect, it is generally 

 admitted that he had before him a species found in the North- 

 eastern States on various herbaceous plants. Prof. Comstock 

 (1881) figured and redescribed Walker's species, which until 

 lately remained the only known representative of its genus 

 in the country. 



In 1888 Mr. Ashmead described 0. Edwardsn from Cali- 

 fornia, but he knew only the male, and the female still awaits 

 discovery. In 1891 Mr. Douglas published his 0. occidentalism 

 based on specimens found by the present writer in ants' nests 

 in Colorado. Of this the adult male is undescribed. 



0. Anna;, which is easily distinguished by structure and 

 habitat from tlie above, is tlius the fourth Orthezia detected 

 in the United States. A fifth species, 0. insignis, Douglas, 

 has lately been found by Mr. H. 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. Dugfes.
