posterior edge to about the middle of the outer face, at about one-third of its 

 length ; tarsal combs 3.2.0.

 (Paratypes in Bishop Museum, Honolulu, and in Coll. F. Muir.) 

 Allied to M. gracilicauda Blr., of Fiji, but larger and more robust, as well 

 as differently coloured. 



31. Mordellistena kellersi, sp. n. 



Black, with an oblique testaceous basal patch on each elytron, including 

 the shoulder but not reaching the scutellum, and not quite meeting its fellow 

 at about the basal 3rd ; at about the posterior 3rd is a broad transverse band 

 of golden pubescence, the derm beneath it being obscurely reddish, the suture 

 remaining narrowly black. Antennae fuscous, stout, extending little beyond 

 the basal angles of the prothorax, the first four joints slender, the rest stout, 

 not twice as long as wide. Cauda slender, slightly arcuate, posterior tibial 

 combs 3, the uppermost much longer than the other two, running nearly across 

 the outer face and almost reaching the base ; tarsal combs 3.2.0. 



Length : 2|- mm. 



Upolu : Malololelei, vi.1924. 



Tutuila : iv.1918 (Kellers) ; Fagasa, 9. ix.1923 (Swezey and Wilder), 1 

 example from each locality. 



(Paratypes in Bishop Museum, Honolulu, and in Coll. F. Muir.) 



Closely allied to M. sivezeyi, from which it differs in markings. The 

 example from Fagasa varies a little from the type in having the head and 

 thorax largely testaceous. Also allied to M. signatus Mars., of Japan, but 

 rather larger and more densely pubescent. 



32. Mordellistena nigrescens, sp. n. 



Dark brown, almost black, with a rather coarse, dark, sericeous pubescence, 

 the base of the antennae, the anterior legs and all the tarsi testaceous. 

 Antennae with the four basal joints slender, the others thicker, subequal, rather
