COLEOPTERA 567 



a slightly longer thorax and different male characters. The mesosternum is strongly 

 carinate in front, but the carina does not extend further back than the most anterior 

 part of the middle acetabula. The male has a long curvate spine on each side of the 

 last ventral plate, and between the two seven or eight shorter spines ; all the spines are 

 blunt at the tip. One specimen. 



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



(3) Dicstofa augusti/rons, sp. nov. 



• Nigra, antennarum basi palpisque fusco-testaceis, pedibus rufis ; capite, thorace 

 elytrisque opacis ; capite thoraceque dense minus profunde impresso-punctatis, elytris 

 subtiliter ruguloso-punctatis. Long. 5^ mm. 



This in appearance is \^ery similar to D. athctiforntis and D. currax, but is well 

 distinguished by the sculpture of the head and thorax ; the parts of the mouth are 

 elongate and slender, and D. angitstifrons appears to be the species that comes nearest 

 to Etidiestota. There is no carina on the mesosternum. The head is narrower than 

 in the similar forms, and has a small depression on the middle. The male has a long 

 slender spine on each side of the last ventral plate, and between the two about six very 

 slender spines, none of these are sharp, and each one of the middle series is well 

 separated from its neighbours. One specimen. 



Hab. Oahu, Honolulu mountains, 2000 ft. 27. x. 1892 under bark (Perkins). 



Group 2. Species not more than 4 mm. long. Head coarsely punctured. (In 

 D. testacea and D. abcrrans the coarse punctuation is limited to the back part of the 

 head.) 



(4) Dicstota iiiolokaicHsis, sp. nov. 



Robusta, nigricans, antennarum basi palpisque fuscis, pedibus sordide rufis, abdo- 

 mine rufo-piceo ; capite fortiter punctate ; thorace minus fortiter transverso, medio vage 

 impresso. Long. 3 J mm. 



An obscure insect, not very closely allied to any other ; most similar to D. sjtbpla- 

 giaia, the elytra possessing a faint tinging of red. The antennae are short and stout, 

 the penultimate three or four joints very evidently transverse. Head rather narrow, 

 coarsely and closely punctate, dull. Thorax rather narrow, a good deal narrowed 

 behind, coarsely punctate but with a vague depression on the middle, and there obscurely 

 punctate, dull. Elytra rather finely rugose punctate, dull. Mesosternum carinate to 

 the tip. One specimen. A second individual is smaller and narrower ; it may be the 

 same species but is in bad preservation.
