COLEOPTERA 249 



and rugosely, and with the surface between the punctures distinctly shining. The joints 

 of the antennae (^) towards the apex are also rather shorter and wider. 



A single example taken at Halemanu, Kauai, is larger with longer elytra and has 

 the front of the head more closely punctured, but otherwise resembles the type. I 

 should think it is probably a distinct species. 



Hab. Kauai. High plateau (4000 ft.). 



(4) Cistela subaenescens, sp. nov. 



Nigra ($ piceo-nigra), pedibus antennisque testaceis, his apices versus obscurioribus, 

 elytris subaeneo-micantibus. Long, circa 7 mm., antenn. circa 3 mm. 



Black, or in the ? piceous, the elytra with distinct aeneous glitter. Head and 

 thorax densely punctured. Antennae of the ^ with the terminal joints shortish, and 

 serrate inwardly, deeply grooved beneath, less wide in the ?, testaceous at the base, 

 becoming infuscate towards the apex. Elytra shining, pubescent, aeneous, somewhat 

 densely punctured. 



Hab. Oahu, Waianae mountains (3000 ft.). 



(5) Cistela apicalis, sp. nov. 



Elongata, angustula, nigricans, antennis, pedibus et parte elytrorum apicali, testa- 

 ceis, oculis permagnis. Long. 7 "6 mm. 



Extremely like the preceding, a little more elongate, the elytra with a very faint 

 indication of brassy reflection in certain lights, testaceous on their apical portion, less 

 shining, and less strongly and more obscurely punctured than in C. subaenescens, the 

 antennae entirely clear testaceous, and the eyes decidedly larger. 



Hab. Oahu. Two examples were taken in the mountains at Honolulu in the 

 summer of 1896. 



(6) Cistela montana, sp. nov. 



Nigricans vel piceus, elytris aeneo-micantibus, antennis testaceis, apices versus 

 saepe obscurioribus, antennis brevioribus, articulis apicalibus parum fortiter dilatatis. 

 Long. 6 — 6'5 mm., antenn. vix 2*5 mm. 



A rather smaller species than C. subaenescens, which it greatly resembles, and easily 

 distinguished by the shorter antennae, which have the apical joints much less strongly 

 dilated in the $. In colour and sculpture the two species are identical, and one e.xample 

 of a rufo-piceous colour I suspect is the $ of C. montana. 



Hab. Kauai. Four examples were taken on the high plateau.
