This si^ecies has been confused to a large extent. There is 

 really but little reason for it except tliat the males seem compara- 

 tively rare in collections. Superficially it seems distinct from its 

 nearest ally trigona, as demonstrated by the male antennae. 



As Dr. Smith states, it is a slightly smaller species, with wings 

 less trigonate and longer in proportion. Tlie variation in wing 

 maculation mentioned in the original description is impossible to 

 check at this time ; but there seems no reason to doubt it, as speci- 

 mens before the author show a tendency in that direction. 



The species seems to inhabit British Columbia onlj^, and ap- 

 pears to be the connecting link between "placida" and trigona. 

 The author has seen no authentic trigona from British Columbia. 



GROUP MIRABILIS 



This group contains only a single species — mirabilis. It is 

 easily separated from the rest of the genus by the striate appear- 

 ance of the primaries due to the basal dash extending as far as the 

 t.p. line, while the black filling of the cell is continued basally of 

 the orbicular and outwardly of the reniform. The ordinary spots 

 are white, varying greatly in size. Normal specimens have the 

 reniform large and very consj^icuous. Thorax with a well-developed, 

 distinct, divided crest and usually with a disconcolorous, rufous 

 patch on the dorsum. x\ntennae simple, ciliate, with the setae near 

 the base subequal to the cilia, becoming about twice as long as the 

 cilia near the tip. The ampulla of the clasper is membraneous. 

 This is the only known species in the genus with a well-developed, 

 divided crest ; and not possessing a clasper with a chitenized am- 

 pulla. Discoidalis comes nearest with a considerable vestige of a 

 divided crest in fresh specimens, easily rubbed off and usually not 

 plainly visible.
