Species of Agra of the Amazons Region. 363 
weather is, however, very showery, it is of little use hunting for 
them ; and it is only in certain peculiar states of the weather that 
more than a solitary specimen can be found ina day’s search. 
When the season seems to be favourable to them, beating should 
be resorted to, and then by perseverance a good series of speci- 
mens may be obtained of many species in a few days. All kinds 
of forest yield them; the dry scattered woods and the lofty 
virgin forests containing each their peculiar species ; in the former 
they are small in size, the large and handsome kinds being found 
only in the more luxuriant parts of the great wilderness. 
Baron Chaudoir, who described in his paper above mentioned 
all the new species of mine of which I could afford him duplicates, 
has since kindly compared the remaining species with his own 
rich collection, and given me manuscript descriptions of many of 
them. Out of the forty-seven species of Agridia and Agra here 
recorded as found in the Amazons region, forty-two were found 
by myself, and of these thirty-one were new species.
