Among the unidentified species I have taken here, two are so 
distinct that I describe them as new, and characterize them as 
follows: 
Mordellistena sexnotata, Nn. sp. 
Brownish yellow, sparsely covered with coarse hairs, which 
are finer and more sparse on head. Humeri each with a very dark 
brown spot. Another in middle of elytra, beginning at base sur- 
rounding scutellum and extending backward in triangular shape 
about one third the length. A large nearly round spot on each 
elytron at middle, but not attaining suture. And a sixth spot 
or band across the elytra at posterior fourth, not attaining the tip. 
A fain darker spot on disk of thorax. Tibia with three oblique 
black ridges, the one nearest the tip being shorter. First joint 
of tarsi with two, second with one. Legs all pale, length 3 mm.
