B{hUogra2)hical Notice. 285 



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

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

 been applied to the carinal niari^in of the tcrgum below the 

 projecting angle already referred to. Its exposed exterior 

 surface is Hat, and shoAvs 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 terguni, and partly covered by it, 

 is an imsymmetrical trilobcd 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 oi Balanus. 

 But tlie 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 Balanidw and Yerrucida?, with peculiar 

 affinities towards the Lepadidae.

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

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

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

 tion of the Hcteropterous Hemiptcra inhabiting Italy. The work 

 embraces 27U genera and 7l!3 species, of which 102 are new to the 

 Italian faiina. Interspersed in the text there are descriptions of 

 40 new or little-knoAvn species. The author has added the syno- 

 nyms of the insects. lie 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, although attached to the Austrian empire; for in matters 

 appertiiining to entomology it may be considered to be intimately 

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

 to entomologists.
