COLEOPTERA 577 



This little insect may be distinguished from all the smaller Hawaiian Dicstota by 

 the different thorax, which is loni^^er in proportion to the width. The breast between 

 the middle coxa is very differently formed, the coxae being less widely separated and 

 the space between them formed by a prolongation backwards of the mesosternum, the 

 metasternal prolongation that meets it being very short. The punctuation is a mere 

 delicate roughness of the surface. Although the insect is decidedly variegate, the 

 limits of the tints are very indefinite. Ten specimens, badly preserved.

Phlocopora will be easily distinguished from the other Hawaiian Aleocharidae by 

 the elongate, narrow and depressed form, and the prettily variegate surface. The neck 

 is narrower than it is in Athcta olaac. P. cingulata was discovered by Blackburn 

 on Oahu and Dr Perkins has met with two individuals there. He has also found an 

 example on Lanai that I refer with doubt to this species. It is in bad condition. 



Hab. Oahu, Lanai. — Oahu near Honolulu, under bark (Blackburn) ; Waianae 

 mts. IV. 1S92 ; Waialua coast, ix. 1900 (Perkins). 



(2) Phlocopora diluta, Sharp. 



Phlocopora diluta Sharp, 1. c. 



I feel doubtful whether this may prove distinct from P. cingulata. Having seen 

 but one specimen I must leave the question open. 



Hab. Kauai, in decaying wood on the mountains, August (Blackburn).

This little insect will be recognised from most of the other Aleocharidae by the 

 narrow neck and truncate vertex and by its maritime habit. It is not at all likely to be
