Length, 3-4 mm.; breadth, 1.25-1.75 mm. Holotype female labeled " Guam " and " Kinb." in the collection of the Naturhistoriska Riksmuseum at Stockholm. In addition to the holotype, the following specimens are before me: one, Yona "on dead Areca palm leaf", April 29, 1936, Bryan; seven, Barrigacla, from dead <i>pago (Hibiscus tiliaceus),</i> June 12, Swezey; one, Machanao, from und~r bark of <i>Elaeocarpus,</i> June 30, Swezey; three, Barrigada, from under bark of <i>Jntsia,</i> July 6, Swezey; two, Barrigada, under bark of <i>Intsia bijuga,</i> July 22, Swezey; two, Dededo, from under bark of <i>Hibiscus tiliaceus,</i> Sept. 7, Swezey; and eight at Yigo, from dead bark of <i>Elaeocarpus,</i> Oct. 18, Swezey. The following specimens are from the National Museum material: three labeled " Island Guam " taken by Fullaway, six "in dead tree", July 14, 1937, Oakley, no. <i>37-24077,</i> and 17 taken "on drying tree bark" by Oakley, Sept. 15, 1937, no. 140, 37-26124. The brief description of the salient characters should enable one to recognize this species without much difficulty. It is quite a normal species of the genus.
