 shining, closely punctured, as well as the basal segment of the 

 abdomen, the second and following segments smooth, shining, 

 and delicately punctured. A spot between the antennae, some- 

 times a line at the base of the clypeus, and a minute spot 

 behind the eyes, yellow. Thorax : the anterior margin of the 

 prothorax, the outer margin of the tegulae, the post-scutellum, 

 and the tibiae and tarsi, yellow ; the tibiae with a dark stain at 

 their apex behind, and the apical joints of the tarsi fusco- 

 ferruginous ; wings subhyaline, with a slight fuscous stain 

 along the anterior margin of the superior pair. The abdomen 

 has a fine changeable silky pile, and the basal segment, as well 

 as the metathorax, a thin cinereous downy pubescence ; the 

 pubescence on the disk of the thorax, and on the vertex, brown ; 

 the yellow band on the second segment of the abdomen is con-

 scape in front and the clypeus entirely yellow ; the apical hook 

 of the antennae reddish yellow ; the tibiae and tarsi entirely 

 yellow, the claw -joint only fuscous ; the basal segment in rare 

 instances with a minute yellow spot on each side.
