COLEOPTERA 565 



(3) LiopJiaeiia oahuensis, sp. nov. 



^ Nigerrima, nitlda, capite, thorace, antennis palpis pedibusque pallide flavis; 

 elytris parcissime punctatis. Long, fere 2 mm. 



We have only one example and I am not sure that it is distinct from L. gracilipes. 

 It is a little smaller and the head and thorax are entirely pallid yellow ; and the sculpture 

 on the elytra about the suture is less marked.

EuDiESTOTA, gen. nov. 



Partes oris elongatae, graciles. Presternum medio compresso-carinatum, valde 

 descendens. Metasternum inter coxas minus productum, mesosternum hand attingens, 

 apice acuminato. 



This genus differs from Dicstota by the more elongate mouth-parts, the terminal 

 joint of the labial palp being remarkably slender and elongate ; and by the middle 

 coxae being rather less widely separated and the apex of the metasternum between 

 them being acuminate and not joining the posterior projection of the mesosternum. 

 The only species is very like an Atlieta, and its nearest allies seem to be Dicstota 

 athetiforniis and angiistifrons. 



(i) Eudicstota grandis, sp. nov. 



Elongata, supra deplanata, fusco-nigra, palpis pedibusque fusco-testaceis ; capite, 

 thorace elytrisque opacis, subtiliter granuloso-sculpturatis ; abdomine parcius subobsolete 

 punctato. Long. 6 mm. 



Plate XVI. fig. 15. 



In shape this insect resembles the larger and Hatter species of Atlieta. The 

 antennae are elongate, the penultimate joint about as long as broad ; they are strongly 

 setose, black, the basal two joints a little yellow at the tip. The head is broad and 

 short, dull, with a fine distant sculpture of minute granules. The thorax is a little 

 narrower, the elytra strongly transverse, distinctly narrowed behind, sculptured like the 

 head, but the granules more numerous, in the middle before the base distinctly flattened 

 but scarcely impressed. The elytra are much longer than the thorax, sculptured like it. 

 The abdomen is piceous, obsoletely punctate. The legs are dirty yellow, the femora 

 darker. The male has the last dorsal plate slightly emarginate, with a minute tooth on 

 each side, and between the two with about eight very short serrations, in shape very 

 much like the teeth of a saw. One specimen.
