which makes it possible to correlate the species definitely 
with names subsequently proposed. 
Malaais excavata is a widespread species and is, as 
one might expect, subject to considerable variation. This 
variation in the species accounts for much of the synon- 
ymy cited above. The species occurs from Mexico to 
Argentina. I have seen specimens or records of speci- 
mens (drawings, photographs) from the countries cited 
below. Malazxis evcavata may be found in other adja- 
cent countries as botanical exploration progresses. 
Mexico, Costa Rica, Panama, Colombia, Keuador/, 
Bolivia, Peru, Brazil and Argentina.
