20. Anaballus amplicollis (Fairmaire) (pl. 2, A).

Acalles aniplicollis Fairmaire, Rev. Mag. Zool. II, 1: 36, 514, 1849.

Inialiodes pusillus Karsh, Berl. Ent. Zeitschr. 25: 10, pl. 1, fig. 15, 1881.

This is an easily recognized species because of its expanded prothorax, subquadrate elytra and brownish and orange scaling. For more detailed description and discussion see my " Cryptorrhynchinae of the Austral Islands" (B. P. Bishop Mus., 0cc. Papers 12(17): 4-5, fig. 1 , a, 1936).

This species is widespread throughout the Pacific, at least from New Caledonia eastward. In southeastern Polynesia I found it most frequently associated with the fallen fruits of Inocarpus edulis .

In the collections before me there are the following specimens from Guam: three specimens, Upi Trail, reared from Cycas seed, May 5, 1936, Swezey; one, May 11, Usinger; eight, Piti, from fallen fruit of breadfruit, May 22, Swezey; nine specimens with the same data, May 23; three specimens, June 18, seven specimens, on plateau at Talofofo, June 17, reared by Swezey from gulos seed; and one, Barrigada, from Intsia , July 6, Swezey. The following specimens are from the National Museum material: 54 specimens taken by Oakley from Ochrocarpus obovalis , Jan. 14, 1938, no. 523, 38-9037, and one specimen taken in quarantine in San Francisco Aug. 1, 1922 from Cycas circinalis from Guam .
