and about half as long as the first tarsal joint. The antennie 
are slender, joints 2 and 3 elongate, subequal, joints 4-11 
nearly twice as long and much thicker. 
Length 4 mm. with (3; mm. without) style.

Mordellistena consimilis, sp. n. 
Rufo-fulvous, pygidium about twice as long as hypo- 
pygium. Very similar to M. dodonee, but differing in the 
comb-ridges of the posterior tibize and tarsi. On the tibiz 
are four ridges, one subapical, parallel with the apex, the 
other three longer, equal, and much more oblique, the 
uppermost extending from about halfway along the posterior 
edge almost to the base; the tarsal ridges are 3.2.2. 
Tibial spurs very unequal, the inner more than twice as long 
as the outer and reaching the third ridge of the first tarsal 
joint. 
Length 33 mm. with (3 mm. without) style.

That the slight differences between this species and 
M. dodonee are not merely sexual is certain, since the g 
of each, with the genital organs protruding, is identifiable

I am unable, however, to detect any obviously 2 individual. 
Mordellistena gracihcauda, sp. un. 
Flavo-testaceous, with a long, slender, somewhat sinuate, 
anal style, more than three times as long as hypopygium. 
Combs of posterior tibiew four in number, one very short 
subapical, parallel with apex, the second close to it and but 
little longer, but more oblique, then two very long, very 
strongly oblique, the first reaching halfway up the posterior 
edge of the tibizw, the other starting a little above it and 
reaching almost to the base; tarsal combs distinct, 3.2.2. 
Tibial spurs very unequal, the inner nearly as long as the 
first tarsal joint. 
Length 2? mm. with (2 mm. without) anal style. 
2 ex., Labasa, Dec. 1921 (R. Veitch). 
Readily distinguished among the uniformly rufous or 
flavous species by its smaller size and paler coloration. The 
form of the anal style is very different, resemblig that of 
M. wanthocephala, but the insect, apart from its different 
colour, is of rather stouter build and with very different 
tibial comb-ridges.
