13. Leptocorisa acuta (Thunberg) .

Cime.1:acuta Thunberg, Dis. Ent. Ins. Spec. 2: 34, 1783.

This species is clearly acuta (see China's revision of the Oriental species, Bull. Ent. Res. 14: 235-239, 1924) on the basis of the distinctive male genital claspers, and agrees with all specimens available to me from the Carolines and Philippines in antenna! and rostral characters. However, the basal segment of the antennae is fulvous or darker in color with the apex often black. It seems evident that this color character is unreliable for the separation of species in the acuta-varicornis group. Varicornis is at hand from Fiji, Samoa, the Solomon Islands, and New Caledonia. Guam specimens of acuta include one collected by Fullaway (1192); one by Hornbostel in 1923; 16 specimens, Inarajan, May 7, May 14, June 8; eight specimens, Piti, May 1, May 9, and July 13; and two specimens, Agana Swamp, May 4. All collected by Swezey and Usinger on sedges, on Paspalum orbiculare, most commonly on rice, and at light .
