and about lialf as long as the first tarsal joint. Tlic aiitcMiii;e 

 arc slender, joints 2 and 3 elongate, subequal, jonits 1-1 1 

 nearly twice as long and much thicker. 



Length 4 mm. with {S^ mm. without) style.

Mordellistena consiniilis, sp. n. 



Rufo-fulvous, pygidium about twice as long as hypo- 

 ])ygiura. Very similar to M. dodonets, but differing in the 

 comb-ridges of the posterior tibine and tarsi. On the tibiie 

 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 3f mm. with (3 mm. without) style.

That the slight dill'ereuces between this species and 

 M. dodonece are not merely sexual is certain, since the ^ 

 of each, with the genital organs protruding, is identifiable 

 I am unable, however, to detect any obviously ? individual. 



Mordellistena gracilicauda, sp. n. 



Flavo-testaceous, with a long, slender, somewhat sinuate, 

 anal style, more than three times as long as hypo])ygiuni. 

 Combs of posterior tibite 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 tibiie, 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 tlie 

 first tarsal joint. 



Length 2| mm. with (2 mm. without) anal style. 



2 ex., Labasa, Dec. 1921 («. Veitch). 



Readily distinguished among the uniformly rufous or 

 fiavous species by its smaller size and \ya\c\- coloration. The 

 form of the anal style is very difi'erent, resemblii.g that ot" 

 M. xanthocephala, but the insect, apart from its difi'erent 

 colour, is of rather stouter build and with very diilcreut 

 tibial comb-ridges.
