Types. — Holotype, an adult female, allotype and para types of 

 adults and larvae in the collection of the Department of Ento- 

 mology of Stanford University. Paratypes in the collections of 

 Mr. H. S. Smith and Mr. E. O. Essig. Type locality, Stevens 

 Creek, Santa Clara County, Calif. 



Host and distribution. — On leaves, branches and trunk of 

 Platamis racemosa (sycamore), Pasadena, Calif., and Stevens 

 Creek, Santa Clara Co., Calif. 



This is the only species of MargarodincB as yet recorded in 

 which the mouthparts are retained in the adult female, a fact 

 that seems amply to justify the naming of a new genus. The 

 adult female appears, aside from the possession of mouth-parts, 

 to approach most closely the genus Steingelia Nassonow^ a genus

of two Species, one of ^'hich,5. gorodetskia Nass., occurs in Russia 

 (host not recorded) and the other 5. hrittanica (Green) on birch 

 in England. The latter species was referred by its author to the 

 genus Kuwania Ckll., but it is obviously not very closely related 

 to the type species, K. quercus (Kuw.) as cotype specimens of the 

 latter before me show, the most significant dififerences being in 

 the structure of the legs. Whether it is a synonym of 5. gorodetskia 

 Nass., as suggested by Sasscer in his Catalogue of Recently De- 

 scribed Coccidae for 1915, can hardly be determined without know- 

 ledge of the larval forms which is lacking in the case of both these 

 species. 



Credit for the discovery of the species here described is due 

 Dr. A. G. Smith, of Pasadena, who forwarded specimens to Mr.
