T. tricincta Harris. 



Blue-black. Fore wings opaque; hind wings transparent, with 

 the border, fringe, and a short transverse line near the middle 

 black; palpi at tip, collar, a spot on each shoulder, and three bands 

 on the abdomen yellow; antennae short, black; four posterior tibias 

 banded with orange ; tarsi yellow, tipped with black ; tail flat, with 

 two longitudinal yellow lines. Expands from one inch to one inch

This species seems to come near to the European T. asiliformis; 

 but the male has only three yellow abdominal bands ; while in the 

 asiliformis there are five bands in the male sex. The antennae are 

 shorter and thicker than in the following species, and are furnished 

 beneath with a double row of short pectinations or teeth, which 

 are thickly fringed with hairs. The sexes were captured together 

 upon the common tansy.
