This elongate, subparallel-sided, densely squamose species with its coarsely punctate elytral striae, its hind femora projecting beyond the apices of the elytra, and its prosternum developed into a strong receptacle behind the coxae is easily recognized. It varies greatly in size; the extremes in length in the specimens at hand are 3.5-8.0 mm.

The following specimens from Guam are before me: two, Agana, May 8, 1936, Bryan; 9 labeled " Island Guam ", Fullaway; and six taken "in dead tree", July 14, 1937 (by Oakley?), no. 37-24077. There are also five specimens among the National Museum material that were collected by C. Bignell in 1917 at Fulakora, Solomon Islands. In Bishop Museum there is a large series of specimens taken by J. A. Kusche at Guadalcanar, Solomon Islands, in January 1921.

This species has evidently not been listed from either Guam or the Solomons heretofore. It is widespread, however, and is a common insect along the east coast of Australia.
