Haleakala, Maui. Several examples occurred under stones at an 
elevation of about 4000 feet. 
This insect is readily distinguished from D. anomalus 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.
