304 NORTH AMERICAN TRYPETINA. 



the male (the figure is made from a male specimen). The guttate 

 reticulation, which leaves open the extreme basis only, has a 

 brownish-black coloring, which assumes a paler hue wherever the 

 drops are nearer together ; upon the stigma, however, and upon 

 the end of the marginal cell, it becomes nearly black ; the stigma 

 contains a rather conspicuous hyaline drop ; the drops upon the 

 remaining surface are in general large, upon the middle of the 

 wing, however, numerous, much smaller drops are interspersed, 

 which perforate the dark coloring between the larger drops; 

 this also takes place between the six large drops which form the 

 usual pyramid of drops, situated beyond the stigma ; upon the 

 portion of the wing beyond this pyramid there are generally but 

 very few little drops, and those are usually in the proximity of 

 the pyramid ; some larger drops, rather distant from each other, 

 are also to be found there, and among these a row of very rounded 

 drops along the margin of the wing, sometimes a little remote 

 from it; they are either of very unequal size (as in the figure), 

 or of the same size ; the proximity of the posterior crossvein 

 shows a more considerable space, which is but little perforated. 

 The third longitudinal vein is not bristly. 



Hab. Canada (Couper) ; English River (Kennicott) ; Maine 

 (Packard). 



Observation. In the distribution adopted by me for the 

 American species, the present one would belong to the .genus 

 Tephritis. Should my distribution of the European Trypetse be 

 applied to it, the shape of its oral opening and of the proboscis 

 would refer it to Oxyna.
