This is our largest species, the length of the body being 

 fully one third of an inch in both sexes, and of a lighter 

 color than the other species. I suspect that Say had speci- 

 mens both of this and T. terminalis, Uhl., and confounded 

 them together ; his description applies best to this, while 

 he endeavored to include them both when he said, " length, 

 more than one fifth of an inch."

*2. T. TERMINALIS, Uhler Mss. 



This species is darker than T. apicalis^ the head and 

 thorax being sometimes pitchy black, at others showing 

 upon these parts reddish brown spots similarly disposed to 

 those upon T. apicalis ; the two broad transverse fasciae 

 and the terminal spot upon the outside of posterior femora, 

 which are only faintly indicated in T. apicalis, are here 

 black and very distinct ; the wings reach only the tip of 

 the abdomen, while in the males of T. apicalis they extend 

 considerably beyond it ; it is a much smaller species than 

 the preceding, and occupies a more northern area. Length 

 from .25 to .30 inches.

3. T. MINUTUS, nov. sp. 



This species resembles T. terminalis very much in its 

 markings and coloration ; but it is in general darker, and the 

 markings are more distinct. The middle femora and tibiae, 

 and the posterior femora are very dark with narrow white 

 bands, sometimes broken ; the segments of the abdomen 

 are bordered with white posteriorly ; the wings in the only
