The only two known males of this species were taken east of Porto Velho 

 where the woods trail crossed a low stretch of ground. In January there 

 was running water here but in May this had disappeared though the creek 

 bed was damp and rankly overgrown, and only by stooping and crawling 

 could one still follow it. In this jungle, associated with Suhaeschna fran- 

 cesca, mi7ior was captured. 



The male abdominal appendages of minor are strikingly like those of 

 solutus, from which species it is separated at once by the color of the face 

 and the abdominal pattern, especially of segments 3-5. Minor is the 

 smallest known species of the genus.
