 minutely coufluently punctulate; legs and abdomen rufous; antennae 

 black, tip of joint sixth and joints seven to eleven, white, the three 

 basal joints of flagellura very long and gradually subequal, the fourth 

 hardly half the length of the third, the joints beyond being very short 

 and only a little longer than thick. 



Thorax with the parapsidal grooves obliterated posteriorly ; the meta- 

 thorax is armed at the posterior lateral corners with a prominent, com- 

 pressed, acute yellow spine, the posterior face being coarsely rugose 

 with irregular raised lines and ridges, while at the base on the sides 

 it is densely continently punctate ; there is but one transverse carina 

 which is near the base which curves laterally outwardly and then in- 

 wardly includiug inside the curve the oval spiracles. Wings fuliginous ; 

 stigma and veins piceo-black; areolet pentagonal, but the outer nervure 

 is icanting ; the cubitus is without a stump of a vein. 



Habitat.— Texas. 



Described from one specimen in Belfrage collection.

 open areolet, but as I know of no other genus into which it could be 

 placed it may remain here for the present.

 large, pentagonal, the cubitus without a stump of a vein.
