D. TEREBEATUS, sp. 110V. 



Convexus, nitidus, niger, antennis palpisque rujis, pedibus (prcecipue 

 genubus tarsisque) plus minusve rufescentibus; protliorace transverso, antice 

 vix emarginato, postice fortius angustato, basi utrinque impresso, angulis pos- 

 ticis rotundatis, lateribus fortius rotundatis angustissime marginatis, margine 

 reflexo trans basin deficiente; elytris oblongis fortiter striatis, striis parcius 

 profunde punctatis, apicem versus obsoletis, interstitiis angustis, humeris 

 rotundatis, metasterno punctato. Long. 8 mm. 



Haleakala, Maui. Several examples occurred under stones at an 

 elevation of about 4000 feet. 



This insect is readily distinguished from D. anomalies by the 

 following characters : — The thorax is considerably narrowed behind, 

 and has the base unmargined ; the elytra are much narrower than 

 those of anomalus, and the striae are much more sparingly and coarsely 

 punctured. The rather coarsely punctured metasternum also differ- 

 entiates it.
