Coleoptera from the TLnoaiian Islands. 53 



invisible punctuation and pubescence, and excessively 

 obsoletely impressed. Elytra rather longer tlian the 

 thorax, very densely and finely punctured and pubescent, 

 but not so extremely finely as the thorax. Hind body 

 rather elongate, slightly dilated fi-om the base to near the 

 apex, densely and finely punctured. Legs dirty yellow. 



Although the head and thorax of this species give it a 

 great resemblance to T. exiguus, the elytra and hind body 

 are more after the pattern of T. elongatidus. The antenn;© 

 are considerably longer than in T. exiguus. 



Found in the salt marshes of Oahu. 



Glyptoma Blackhurni, n. sp. Nigricans, opacus, antennis 

 pedibusque rufis, capite thoraceque longitudinaliter strigu- 

 losis, fere sine lineis elevatis, hoc vix transverse ; elytris 

 thorace conspicue longioribus, lineis elevatis rcctis fere 

 integris ; abdomine per-opaco, segmentorum marginibus 

 posterioribus rufescentibus. Long. 3§ mm. 



Antenna much shorter than head and thorax; joints 

 8 — 10 strongly transverse ; 7th scarcely transverse, but 

 slightly broader than the preceding one. Head distinctly 

 strigulose, but without any distinct elevated lines. 

 Thorax a little broader than long, a little narrower than 

 the elytra, the sides from the front to near the base nearly 

 straight, a little in front of the base they become some- 

 what narrow^ed, the hind angles rectangular ; the surface 

 is longitudinally strigose, and slightly uneven. The elytra 

 are distinctly longer than the thorax, and have five or six 

 somewhat fine elevated lines extending for nearly their 

 whole length. 



This species has been found by Mr. Blackburn in 

 Several of the islands. 



Glyptoma brevipenne, n. sp. Rufo-obscurus, opacus, 

 capite tlioraceque longitudinaliter strigulosis, fere sine 

 lineis elevatis, hoc subtransverso ; elytris thoracis fere 

 longitudine, lineis elevatis rectis fere integris ; abdomine 

 per-opaco. Long. 3f mm. 



This species is very closely allied to G. Blackhurni in 

 all points except that it has the elytra very much shorter. 



Found rarely in the mountains of Oahu.
