Most closely related to Mecidea kristenseni but easily distinguished 

 by details of the male genitalia, the proportionately broader second 

 antennal segment of both sexes, and the less convex posterior lobe of 

 the pronotum. Judging from material at hand prolixa is, on an aver- 

 age, the smallest species of Mecidea and with the possible exception 

 of kristenseni it is the darkest in color. This dark color is not char- 

 acteristic of all specimens but there is a decided tendency for all 

 punctures and all points w^here hair attach to be fuscus.
