Polyangseus maculatus, sp. nov. (PI. VII, fig. 20.) 



Brown ; head darker brown ; palpi and basal segments of antennae brown ; other 

 segments pale ; thorax grayish brown ; the dorsum almost covered by the three darker 

 brown stripes ; halteres and feet pale ; tips of the femora, tibia and tarsi, and sometimes 

 the base of the tibia also, brown, abdomen brown, lighter toward the base, wings hya- 

 line ; with brownish spots on the origin of the prrefurca, at the base of the second sub- 

 marginal and the first posterior cells, at the tip of the auxiliaiy vein and on nearly all 

 the cross veins ; stigma pale ; auxiliary vein ends in the costa opposite the first marginal 

 cross vein ; petiole of first submarginal cell about the length of the posterior crossvein ; 

 inner end of the second submarginal cell but little before the inner end of the first pos- 

 terior cell ; the supernumerary cross veins in the submarginal cells seem to draw the 

 veins which they connect toward each other ; second posterior cell short ; posterior 

 cross vein before the inner end of the discal cell ; seventh vein very slightly sinuate. 

 Length, male 4 mm.; wing 5 mm. 



Habitat : Seattle, Wash., one male (type). Olympia, one male.

Cylindrotoma splendens, sp. nov. (PI. VIII, fig. 21.) 



Pale yellow and black ; head very pale yellow almost whitish ; occiput, front, 

 rostrum and palpi brown ; first and second segments of antennas whitish, first with a 

 brown ring, other segments brown, cylindrical, if bent back they would reach to about 

 the middle of the first abdominal segment ; thorax very pale yellow or whitish ; dor- 

 sum with three opaque black stripes ; the lateral ones merge anteriorly into broader 

 brown stripes which curve in and meet the median stripe ; collare with a black band ; 

 a large black spot on the pleura between the base of the wing and the anterior coxae, 

 another over the anterior coxae, and another between the first and second pair of 

 coxae ; a smaller one just in front of the base of the halteres, and a double on the 

 posterior border of the metanotum ; scutellum with a median brown stripe ; halteres 

 pale, slightly infuscated above and* at the tips ; legs brown, base of femora lighter; 

 tarsi and tips of the tibia darker ; abdomen black ; male forceps large, brownish 

 posteriorly; wings rather narrow, hyaline; stigma pale; veins brown; auxiliary 

 vein ends abruptly just before the stigma ; the small cross vein connecting the first 

 longitudinal vein with the costa is very faint and situated a little beyond the middle 

 of the stigma ; submarginal cell either longer or shorter than the first posterior 

 cell. (In two of my specimens it is longer in one wing and shorter in the other.) 

 Thus the pnefurca may either end in the submarginal cell or in the first posterior 

 cell ; five posterior cells, the second sessile ; discal cell elongated, somewhat pointed 

 anteriorly ; posterior cross vein a little before the middle of the discal cell ; fifth 

 vein incurved at the tip. Length, male 9 ram.; wing 9 mm. 



Habitat: Unalaska, three males. (Kincaid.) Type no. 145.
