Rhygcliium dorsale Fab. 

 A 9 from Fedor, Texas, and another from Oslar, Berkeley, Col., 

 agreeing with Saussure's figure on PI. XIII, f. 9 (Ve.«pides i). A 

 % from Fedor is very dark colored, the front, vertex, occiput, the 

 greater part of the mesothorax and the abdomen, except the yellow 

 apical margins, being black. It is very variable as regards colora- 

 tion ; the red basal three joints of the antennae, fuscous violaceous 

 wings and the yellow bands on the basal abdominal segments appear 

 to be common to all the numerous varieties.
