May 1935; Valle Medellm, Colombia, September 1945 (M. Gallego). 

 There is also a single female from Porto Bello, Brazil, collected by 

 Busck, which is difficult to separate from this species. 



Forewing 4.5-5 mm. in length, well rounded apically, with five 

 branches to radius; inner gradates, usually consisting of seven cross- 

 veins, very straight, narrowly margined with brown with a narrow 

 hyaline zone external to it. This hyaline zone is not mentioned by 

 Carpenter, but otherwise his description of the type of M. minor 

 agrees. 



The genitalia of the male in the above lot were dissected and 

 found to be structurally compatible with the description and figures 

 given by Carpenter. Anal plate subtriangular in lateral view; 10th 

 sternite with broad lateral "wings"; aedeagus in the form of a pair of 

 long, slender processes, arising from subquadrate phallobase; para- 

 meres fused anteriorly into a somewhat subtriangular basal piece, and 

 separated posteriorly into two large arms, each ending in a short, 

 pointed process. A pair of the characteristic toothlike projections 

 present between base and arms of parameres.
