MR. J. S. BALT OS' SOME GESERA 
The specimen from which I originally drew up the diagnosis 
of this species (a $ ) had been carded, and the apex of the 
abdomen was so obscured by gum that I described it as 
entire ; since then I have had the opportunity of examining many 
specimens of both sexes, and find that the apex of the female 
anal segment is distinctly, although slightly, sinuate on each 
side.

Vertex in the S with an elevated ridge, placed obliquely on 
each side just above the eye and running inwards to nearly 
meet its fellow in the median line ; antennae in the <J with the 
basal joint thickened, slightly curved, clavate, its outer edge sub- 
carinate; second joint small, the third thickened and subclavate, 
its apex truncate ; the fourth and fifth also thickened, dilated 
laterally, subtrigonate, each shorter than the third ; the apex of 
the fourth obliquely truncate, its anterior and outer angle 
produced, acute or subacute ; the fifth wdth its outer sur- 
face deeply concave, the anterior angles of the concavity 
acute. Thorax nearly twice as broad as long; sides nearly 
straight and parallel from the base to beyond the middle ;
