Dr. Horvath's work serves to make one thing very evident, and that 

 is the danger American Hemipterologists incur in identifying our Ameri- 

 can forms with European species, being guided only by the more or less 

 imperfect early descriptions. It has always seemed to me that the simplest 

 solution of the problem is to describe the American species in hand as new, 

 and leave it to some monographer to determine the synonymy. This, of 

 course, when the European species is not in hand for minute comparison, 

 because if comparison be possible, there should be no room for doubt. 

 On the other hand, certain entomologists, and they not the least eminent, 

 have a surprising faculty for labelling things "var.," or for offhandedly 

 declaring their identity with other and more familiar forms. Hemip- 

 terology, as the least studied branch of Entomology, has been a great 

 sufferer from this lack of discrimination. •

COCCID.K FROM THE SOCIETY ISLANDS. 



BY R. W. DOANE AND EVELYN HADDEN, STANFORD UNIVERSITY, CALIF. 



During the summer of 1908 the senior author spent a few weeks on 

 some of the islands of this group studying the scale insects infesting the 

 cocoanut tree. An annotated list of these will appear in an early 

 number of the Jour. Eco. Ento. The following is a list of a few other 

 species taken on various plants, most of which we have been unable to 

 have identified. Miss Hadden is responsible for the identifications of 

 these insects, and should be credited with the new species of Parlatoria. 

 Prof. T. D. A. Cockerell kindly examined the new species of Aspidiotus 

 and pointed out some of the important characters, so that species should be 

 credited to Cockerell and Hadden. These are the first Coccidaj recorded 

 from these islands.
