description: 3. Sycoryctes guamensis, new species. Female: 3 mm. long, from head to tip of ovipositor, the body itself being only 0.75 mm., aeneus, antennae fuscous beyond the pedicel but it and the scape yellowish· brown, legs also, except the coxae, which are mostly concolorous with the body. Wings hyaline. Head and thorax shagreened, abdomen more finely sculptured. Head transverse, more than twice as wide as long, eyes oval, convex, red, frontovertex twice as wide as long, ocelli in form of obtuse angle on vertex, the lateral members close to eye margin (less than one diameter removed). Face equally wide. Antennae attached in lower center, on line with lower level of eyes and close together, the genae, postgenae and occiput full and rounded. Antennae rather short (hardly longer than thorax), composed of scape, pedicel, ring joint, 5-jointed funicle and 3-jointed club; scape somewhat expanded basally, more than three times as long as pedicel, which is obconic and twice as wide at apex as the transverse ring joint, funicle joints no wider and subequal in length, which is about twice the width, club not as lorig as scape but more than twice length of pedicel, all these outer joints bearing whorls of stout hairs and many sensory pits. Body depressed; prothorax transverse, about three times as wide as long behind but narrowed in front; mesonotum transverse, twice as wide as long, with parapsidal grooves extending inward from the anterior lateral angle less than half the length of the sclerite; scutellum large, with wide base and rounded apically, almost flat; metanotum transverse. Abdomen elongate-ovate, with wide base and pointed apically. Ovipositor exten&lt;j.ing beyond the tip four times the length of the abdomen, reddish brown for most of its length, but black at base and apex, where it is a little swollen. Legs normal, hind ones stout and flattened throughout, fore tibiae with a strong spur, middle tibiae quite long and with two spurs, tarsi 5-jointed. Forewings short, fairly wide and ro1,1 ndedapically, the disk beset with fine short hairs resembling puncture points, and hind margin bearing a fringe of rather short hairs less than one tenth as long as greatest width of wing; marginal and postmarginal veins subequal and together not much longer than the submarginal; radius diverging at an angle which is quite wide but less than ninety degrees, its length about one half the postmarginal vein, thin at base but expanded apically to form a triangular spur and with four pustular organs in a line extending inward from outer edge near apex. There are also a number of setaceous hairs on the vein and in the field of the disk lying beneath the marginal nervure. Barrigada, June 24, holotype; Yigo, Oct. 21, six paratypes; Mt. Chachao, May 16, one paratype; Sumay Road, June 15, 10 paratypes; all ex figs of large-leaved <i>Ficus,</i> Swezey.
