latter author also indicates the malarial relation, where known, together with 

 the bearing of the species in question upon the epidemiology. 



Turning to our American species, it appears that we listed as transmitters 

 species that had not been proved to be such at that time. 



Anopheles punctipennis has been recently proved capable of transmitting 

 malaria by Dr. W. V. King.* 



Anopheles crucians, which had not been definitely proved a malaria trans- 

 mitter at the time we wrote, has also been demonstrated such by Dr. W. V. King.f 



Anopheles grabhamii appears in a number of compilations as a malaria trans- 

 mitter. We have failed to find any records of investigations with this species. 

 Apparently a statement by Theobald, " probably it also is the definitive host of 

 the malarial parasites," J has been converted into a positive one by the compilers.

Genus Sahethes (page 23). 



Sahethcs goeldii, new species (page 24, footnote), should have been included 

 in the text as it occurs within the geographic limits included in this work. How- 

 ever, this was impossible, as the specimen from Trinidad came to hand after the 

 volume was already in type. The species was first recognized as new from 

 Goeldi's figure, which, by comparison with the actual specimen, proves to be an 

 excellent representation.

The scales of the mesonotum are of the " minute hair-like " type, though 

 rather longer than in C siniiUs and allies, but not of the " narrow curved " 

 type as described.
