polished median spot just above the base of the antennae; above the 

 ocelli with a short median impressed line. Eyes oval, nearly circular 

 in outline, pubescent. Ocelli in a triangle, the lateral ones slightly 

 nearer to the eye margin than to the median ocellus. Mandibles and 

 palpi pale brownish. Antennas 11-jointed, as long as the body and 

 gradually becoming more slender toward the apex. Scape three times 

 as long as thick at the apex, slightly curved ; pedicel minute, obovate ; 

 first flagellar joint four times as long as thick, all the following joints 

 including the last more slender and very slightly shorter. Mesonotum 

 elongate, slightly narrowed anteriorly, its surface shagreened and 

 subopaque ; with three furrows which converge posteriorly and meet 

 an impressed line at the posterior margin; axillae barely meeting 

 medially. Scutellum nearly as long as the mesonotum, narrow, convex ; 

 its surface shagreened. Metathorax very short, rugose. Pleura? nearly 

 smooth ; the mesopleura anteriorly with a row of large punctures. 

 Abdomen somewhat longer than tne thorax ; slightly convex above, but 

 strongly so below when seen in profile. First segment rugose, ex- 

 tremely short; second twice as long as the remaining ones together; 

 with a raised basal rim or margin and a series of short basal longi- 

 tudinal striae; following all very short; apical projecting appendage 

 yellow. Legs brownish-yellow; the coxae and the anterior legs lighter 

 than the four posterior legs which are more nearly rufous. Wings in- 

 fuscated, stigma piceous ; two-thirds as long as the radial vein. 



One specimen from one of the islands in Puget Sound, Wash., 

 collected during July, 1908. 



The species is distinguished from others in our fauna by the 

 subopaque body, nearly equal flagellar joints and the color of the 

 legs with lighter coxae. 



Lygocerus constrictus sp. nov. 

 Male. Length 1.2 — 1.4. mm. Black, the legs except the basal part 

 of the coxae brownish yellow; wings slightly infuscated. Head 

 strongly transverse, nearly three times as wide as thick; front sub- 

 shining, faintly punctate. Eyes nearly circular in outline, faintly 

 pubescent. Ocelli in a broad triangle, the lateral ones equally distant 

 from the eye-margin and the median ocellus. Face strongly convex 

 centrally. Mandibles piceous, palpi pale brown. Antennae 11-jointed, 

 entirely black except the extreme base of the scape which is pale. 

 Scape elongate, slender, about four times as long as thick; pedicel
