Treatment

2. Stephanoderes (Hypothenemus) insularis (Perkins) .

Hypothene1nus insularis Perkins View in CoL , Fauna Hawaii. 2: 181, 1900. Schedl, Stylops 3: 178, 1934 (redescription).

Cryphalus insularis (Perkins) Hagedorn, Coleopt. Cat. 26 (4): 43, 1910.

Piti Sept. 16, under bark of banyan; Piti, Oct. 7 , 9, abundant in dead twigs of orange ; Piti , Oct. 27, in dead branch of breadfruit.

Occurs in the Hawaiian islands.

I have examined the antennae of this species again and found that the funicle is 5-jointed and therefore it has to be placed in the genus Stephanoderes Eichhoff . Two specimens of the large series from Guam are decidedly smaller, 0.7 mm. long, more oval in outline, the declivity commences farther behind and is more gradually convex. The antennal funicle is also 5-jointed, the club more strongly egg-shaped in outline (as far as can be concluded from one mount). These specimens are probably males.
