INSECTS OF SAMOA. 



29. Mordellistena buxtoni, sp. n. (Text-fig. 7). 



Ferrugineous, covered with moderately dense and long, subdepressed 

 pubescence. Eyes with base not much shorter than lateral margin, the distance 

 between them about equal to twice the width of one of them (as viewed from 

 in front). Antennae long, extending to about the middle of the posterior 

 femora ; joints 2 to 4 equal in length, short, obconical ; joints 5 onwards 



longer than 3 and 4 together, and parallel-sided. Pos- 

 terior tibiae stout, apex about one-third as long as 

 posterior side ; latter with two oblique combs above 

 the short subapical one, the first extending from close 

 to apex nearly half way up the tibia and nearly reaching 

 Text-fig. 7—Mordd- the middle of the outer face, the 2nd similar, extend- 

 Ustena buxtoni, sp. n. ; i n g from a little above the first to a point about midway 

 posterior leg. between the upper termination of the first and the 



base of the tibia ; a third shorter comb is sometimes present (Text-fig. 7). 

 Inner spur reaching beyond the middle of the 1st tarsal joint, the outer spur 

 less than half as long ; tarsal combs 3, 2, 2. Cauda elongate, acute. 

 Long. 3 mm. 



Upolu : Apia, ii., iii., viii.-ix., xi.1924 ; Aleipata, iv.1924. 



Tutuila : 760-1200 ft., iv., vi., xii.1918 (Kellers) ; Pago Pago, 9.ix.l923 

 (Swezey and Wilder). 



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



Rather paler than M. samoensis, and considerably smaller, differing notably 

 in the shape of the eyes and in the arrangement of the combs on the posterior 

 tibiae. The female apparently differs only in the antennae and cauda being- 

 somewhat shorter. 



30. Mordellistena swezeyi, sp. n. 



Fuscous or fuscotestaceous, with the fore part of the head, the sides of the 

 thorax and the legs paler, the elytra blackish, with an indeterminate discal pale 

 streak. Antennae moderately stout, all the joints subequal in length, the 

 3rd more slender than the 2nd or 4th ; pygidium slender, slightly sinuous ; 

 tibial and tarsal combs black, tibial combs 2 in addition to the short subapical 

 one, the upper longer comb running from about the apical quarter of the
