 This genus is easily recognised by its elongate parallel- 

 sided shape, and the thick large scale of the petiole, as 

 well as by its short clavate antennae, which hardly reach 

 to the apex of the metathorax in the ^ , and the 

 constricted 1st segment of the abdomen ; maxillary palpi 

 1- or 2-jointed, labial palpi 2-jointed ; wings with one 

 radial cell, two submarginals, and one discoidal.

 maxillary palpi 2-jointed, the 2nd terminating 

 in a hair . . . . . . . . . . . . contracta. 



(1) 2. Darker, puncturation so fine as to be hardly dis- 

 tinguishable even under a somewhat strong lens; 

 maxillary palpi with only a single joint . . . . punctatissima.
