Euglenes guamensis Blair, 1942, new species

Similar in form to E. bifossicollis, but thorax smaller and more strongly transverse, without the prebasal foveae; the puncturation is finer, the coarser hairs more decumbent and not conspicuous, the fine decumbent pubescence exhibiting dark markings on a silvery ground as follows: on thorax an elongate median patch and a smaller spot near each angle; on elytra an irregular transverse band (or three spots united) at basal one fourth, a strongly zigzag transverse band just beyond middle, projecting farthest forward on suture and nearly as far in middle of disk. Antennae.stout (female), joints 4 to 11 of equal thickness, 6 to 10 strongly transverse. Hind femora rather strongly incrassate. Length 1.25 mm.

Libugon Farm, Aug. 10, holotype female, swept from unknown tree; Inarajan, May 7, one female; Piti, Oct. 29, swept from bamboo, one female; Agana, May 15, one example, head and prothorax missing; all collected by Swezey.

Very close to Xylophilus marquesa.nus Blair (B. P. Bishop Mus., Bull. 98: 290, fig. 1, 1935), but rather smaller with stouter antennae and the dark markings of the elytra differently disposed.
