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, Uhlcr 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. tcrtninalis very much in its 

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

 markings are more distinct. The middle femora and tibiee, 

 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
