chiefly resided are : — Cali, a town of importance, situated at 

 about seventy miles from Buenaventura ,\\\ç. Pacific Columbian 

 port. Cali may be considered as a temperate country. Its 

 elevation over the sea is about 3,000 feet, and is surrounded by 

 mountains. Rio Dagua is only a sort of rancheria, used as a 

 halting-place by those who go from Buenaventura to Cali. It 

 is about midway between the two, and belongs to the hot 

 regfion. It is well wooded and watered. 



Here Mr. Rosenberg was attacked with intermittent fever. 

 This, unfortunately kept him indoors a great part of the six 

 months of his residence there, and even now, he is suiïering 

 from it at times. It was in this insalubrious locality that he 

 made his new discoveries in Birds, Reptiles, and Insects. Of 

 the last he collected a large number, and many of them are 

 new to science. The most important novelty among the 

 Coleoptera is what I consider a new genus, of a gigantic size, 

 belonging to the family of HiSPiDAE. 



The Collection of Mr. Rosenberg can be seen at his place 

 of residence, Trenton Villa, 109, Fernhead Road, St. Peter's 

 Park, Paddington, London, W.

Several specimens of both sexes of this remarkable new 



species were collected at Rio Dagua, Colombia. 



At first sight, I took them for P. amobilis ; but in 



comparing them with that species, I was agreeably surprised to 



find that they were quite distinct, and even more beautifully 



coloured on the underside than P. amabilis and decorata.
