FAUNA HAWAIIENSIS 



(ii) Diesiota subplagiata, sp. nov.. 



Nigricans, antennarum basi pedibusque fusco-rufis, pedibus sordide testaceis, elytris 

 obsoletissime rufo-plagiatis ; capite fortiter punctato, thorace elytrisque subtiliter sculp- 

 turatis, opacis. Long. 3 mm. 



Antennae short, the penultimate five joints transverse. Head not very broad, with 

 a more distinct punctuation than the thorax. Thorax short, much narrower than the 

 elytra, very dull, finely punctate ; elytra much longer than the thorax, finely sculptured, 

 each vaguely longitudinally rufescent near the suture. Legs rather slender, pubes- 

 cence of tibiae slight. Mesosternum not carinate. Male with a minute, slightly 

 curvate spine on each side of the hind margin of the last dorsal plate, and between 

 them about ten very minute teeth. 



Hab. Lanai, 3000 ft. vi. 1894 (Perkins). 



(12) Diestota frontalis, sp. nov. 



Nigricans, antennarum basi palpisque fusco-testaceis, pedibus testaceis, minus opaca, 

 capite sat fortiter punctato anterius nitido, elytris versus suturam late sed vage pallidis. 

 Long. 2|- mm. 



This is smaller than D. subplagiata, it is not so dull, the front part of the head 

 being shining, and the antennae are shorter. The resemblance to D. lurida is still 

 greater, but that species has the surface more shining, with more minute punctuation and 

 pubescence, and the large punctures on the back of the head more effaced. 



The antennae are short and stout, joints 5 — 10 transverse. The head has numerous 

 and rather large impressed punctures except on the epistome, where it is smooth and 

 shining. The thorax is closely and rather coarsely sculptured with impressed punctures. 

 The sculpture of the elytra is fine. The mesosternum obscurely carinate. One specimen, 

 probably female. 



Hab. Oahu, mountains near Honolulu, 2000 ft., under bark, 27. x. 1S92 (no. 47, 

 Perkins). 



(13) Dicstota sordida, sp. nov. 



Nigricans, antennarum basi palpisque fusco-testaceis, pedibus testaceis ; capite 

 fortiter punctato, thorace elytrisque subtiliter sculpturatis, opacis. Long. 2^ mm. 



Closely allied to D. subplagiata, but smaller, and the elytra have not the vague 

 rufescent patch of the larger species. The antennae are not so stout as in some of the 

 allied forms, but the penultimate three or four joints are distinctly transverse. The 

 mesosternum is carinate on the anterior part only. The male characters are much the 

 same as in D. subplagiata. 



Hab. Lanai, 2000 ft. i. 1894 (no. 91, Perkins).
