The American and African species of this genus are very closely allied, and all of 

 them vary enormously in size, much as in certain genera of Brenthidse. The males, as 

 is well known, have a dense brush of fulvous hairs on the rostrum and the anterior legs 

 more or less elongated. JR. barbirostris is replaced in the Antilles by E. scrutator 

 (Oliv.) *, which has the anterior tibiae ciiiate in the male as in the African M. nigra f .

A common insect in the warmer parts of Central America, but apparently local, to 

 judge from the limited number of localities whence specimens have been obtained. It 

 is extremely variable in size J, and in the corresponding development of the rostrum, 

 antennas, and legs in the males. Examples of the same size from Mexico and Brazil 

 agree periectly inter se, and there is no reason whatever for separating the large 



Mexican 



pies (R. ebriosa) from those from B 



R. affaber (as already 



Chevrolat §) and R. costalis are small forms of the same species. It is unnecessary 

 give the full synonymy here, for which Schonherr's work 3 must be consulted.
