At the Museo di Storia Naturale di Firenze (Via Romana 19), 

 where also are the rooms of the Societa Entomologica Italiana, 

 and of Prof. Targioni Tozzetti, the well-known economic ento- 

 mologist, the writer was informed by Dr. Angelo Senna, assistant 

 in Entomology, that the only important collections of insects 

 here are Rondani's collection of Italian Diptera, including his 

 types, and Fuchs' collection of European Coleoptera. These

RANDOM NOTES ON COLEOPTERA. 



By JOHN HAMILTON, M.D. 



Tachycellus (Aaipalpus) nitidus Dej., Acupalpus obsoletus Say, 

 Bradycellus nitidus Mann , LeConte, Glycerins nitidus Casey. 

 Scarcely a species in the whole range of Coleoptera exhibits 

 greater diversity among the individuals in size and color, varying 

 from .14 to .28 inch, in length, and from bronzed black to testa- 

 ceous. According to Dr. Horn the small form, which is the 

 black one is usually the male, while the large testaceous indi- 

 viduals are mostly females, a statement I have never met with 

 in print. I did not recognize the bronze form, lately come to 

 hand, as belonging to that species till so assured. Whatever its 

 size and color, it may be readily known by the obliteration of all 

 the elytral striae except the sutural, which is equally deep from 

 base to apex.
