HlSTERID/E 2OI 



differs from subnitidus in the notably small and everywhere widely 

 separated punctures of the elytra and in its rather less transverse 

 prothorax. 



This is one of the largest and most isolated families of the old 

 Clavicornia and, as it exhibits no decided relationship with any of 

 the other large divisions of the Coleoptera, it may be considered 

 a representative family of an order having the name Clavicornia, 

 in absence of any more fitting. It is safe to say that not three- 

 fourths of the species now forming our collections have ever been 

 described. The collection of the writer has increased greatly 

 since his early work in the family, and it seems desirable to bring 

 it up to date by naming the numerous nondescripts. Mr. F. G. 

 Carnochan has, it is understood, a monographic treatment of the 

 Hololeptids in view, and this part of the family is therefore omitted 

 for the present. 



Platysoma Leach 



A large genus as heretofore constituted, but Mr. Lewis has sub- 

 divided it into numerous subgenera, some of which will doubtless 

 be accorded generic weight in times to come. In the true Platy- 

 soma, a species which I described under the name tabella (Ann. N. Y. 

 Acad. Sci., 1893, p. 551) has been reduced to synonymy by Mr. 

 Lewis, and this is followed by Mr. Bickhardt in his catalogue of the 

 Schenkling series,* but this is not correct. The type of tabella 

 was unlabeled in the Levette collection and I surmised that it might 

 have been taken in Indiana, but subsequent study shows that it is 

 from California. Segregating all of the California and Arizona 

 examples in my collection and comparing them as a series with 

 depressa Lee. (lecontei Mars.) , from the Atlantic regions, demonstrates 

 at once that tabella is a larger, broader species, with more abruptly 

 and broadly truncate elytra and relatively longer and less trans- 

 verse prothorax, broader pygidia, less punctate abdomen and broader 



* The compiler of a general catalogue, such as this, confers so signal a benefit upon 

 all workers in the branch considered, that it ill becomes one to criticize adversely, and 

 I pass over numerous typographic errors in page numbers and other such details without 

 comment; but it does seem as though Mr. Bickhardt might give some other locality data 

 than "Nord-Amerika," in referring to species from the U. S. of America. One might 

 with equal propriety give the locality Asia for a Japanese or Persian species.
