it is difficult not to regard it as part of the same individual, 

 in wliicli case it can only be the upper latus, and have 

 been applied to the carinal margin of the tergum below the 

 projecting angle already referred to. Its exposed exterior 

 surface is flat, and shows broad, slightly elevated, wavy ribs, 

 crossed by faint vertical lines of growth. The two sides seen 

 are straight and meet at an angle of 45°. 



On the other side of the tergum, and partly covered by it, 

 is an unsymmetrical trilobed shelly mass, which I suspect to 

 be one of the compartments. If so, the subparallel curved 

 grooves upon it remind one rather of Verruca than of Balanus. 

 But the specimen seems small for valves so large as those 

 described. 



Altogether the plates preserved would incline one to suspect 

 that there were no more. By no ordinary arrangement could 

 the valves close the aperture, if there were six. I therefore 

 incline to regard the specimen as the type of a new family in- 

 termediate between Balanidai and Vcrrucida?, with peculiar 

 affinities towards the Lepadidte.

CataJoijus methodicus ct synonymicus Hemipterorwn Ileteropterorum 

 Italue indigenorum, accedit descriptio cdiquot specicrum vel mhiHS

This Catalogue is the result of the study of many years, in which 

 the author, a distiuguishcd Professor in the Medical Faculty of the 

 University of Turin, has devoted his special attention to the collec- 

 tion of the Heteropterous Heniiptcra inhabiting Italy. The work 

 embraces 279 genera and 713 species, of which 162 are new to the 

 Italian fauna. Interspersed in the text there arc descriptions of 

 40 new or littlc4£nown species. The author has added the syno- 

 nyms of the insects. He has embraced the Hemiptcra of the Italian 

 islands as well as those of the peninsula itself- — those of Corsica, 

 although belonging to the French Empire, and also of Venetian 

 Dalmatia, althoi;gh attached to the Austrian empire ; for in matters 

 appertaining to entomology it may be considered to be intimately 

 connected with Italy. This Catalogue Avill be found to be valuable 

 to entomologists.
