COLEOPTERA 445 



explanate in front. The pygidium of the female is moderately coarsely punctured, the 

 hind margin not truncate, but scarcely forming an angle in the middle ; the last ventral 

 narrow truncate at the tip, with moderately long cilia on each side, leaving only a small 

 space between them. 



One of the two specimens has the hind angles of the thorax rounded, but is I think 

 the same species as the type in which they are nearly rectangular but slightly obtuse. 

 Two specimens. 



H.-\i!. Oahu, end of Koolau range near Honolulu, August 1900 (no. 7S5, Perkins).

This species is very variable in colour as recorded by Mr Blackburn. It is dis- 

 tinguished from other species near it by the pygidium of the female being notched and 

 indented at the tip (see Plate XI\'. fig. 12 a). The dorsal aspect of the male's last abdo- 

 minal segment is shown in Plate XIV. fig. 12 b. The individuals are of large size and 

 very broad torm, with transverse thorax, much explanate at the sides, the disc with 

 indications of slight depressions, the punctuation coarse and rough, but not crowded ; 

 the sulcation and punctuation of the elytra slight but quite distinct. The sides of 

 the elytra rather strongly explanate. The species appears to be rare as well as variable, 

 and I have altogether seen scarcely a dozen examples. 



Hab. Oahu. Kawailoa gulch, "from the gulch itself and very far up" (no. 41), 

 " Kawailoa, from base ot leaves of Ercvciiuiia" (no. 54), "near head of South branch 

 ofTvawailoa gulch" (no. 239) ; mountains near Honolulu (no. 626, &c., Perkins). Also 

 found on flowers of palm in mountain forests (Blackburn). 



Goniorvctus latits, var. ciulu'its, var. nov. 



Two male specimens difter from the others inasmuch as the last ventral plate has 

 a large depression extending along the middle for the greater part of the length. It is 

 possible they may pro\e to be distinct, but I see no other character of importance to 

 separate them from small specimens of G. latus. They were taken in the same locality 

 and at the same date as other specimens that I assign to G. latits, and that are destitute 

 of this character.

The only specimen that has been found appears to be allied to G. latits, and
