Conchaspis newsteadi Ckll. (sp. n.) Vera Cruz (Vera Cruz). 

 On frangipanni, Feb. 26, 1896. Coll. Towns. 



Peculiar to Mexico. "Surprising discovery! Three species of 

 the genus are now known ; angrceci in Jamaica on an orchid (Hope 

 Gardens), with the variety hibisct collected by Townsend in Tampico ; 

 another not yet published, found by Green in Ceylon ; and now the 

 third, this one found by Townsend in Vera Cruz. What the native 

 country of the genus is, I know not. It may be oriental. I called this 

 species after Mr. Newstead because he gave a very good illustrated ac- 

 count of the genus (as PseiidingUsia) only a few months after I pub- 

 lished it." (Ckll.)
