Sept. I900.] Doane: North American Tipulid.« 193 



origin of the prsefurca and the tips of nearly all the longitudinal veins with brown 

 clouds ; the posterior veins faintly bordered with brown ; veins brown ; origin of the 

 praefurca with the stump of a vein ; tip of the auxiliary vein nearly opposite the inner 

 end of the second submarginal cell which is considerably longer than the first sub- 

 marginal cell ; marginal cross vein just a little beyond the base of the latter cell ; four 

 posterior cells ; posterior cross vein near the inner end of the discal cell. Ten of the 

 seventeen specimens that I have before me show these markings ; five of the others 

 have the discal cell open and the other two have the discal cell closed, but have a 

 brown spot on the posterior side of the middle of the fourth longitudinal vein and an- 

 other in the axillary cell. These were all collected on the same date. Length, male 

 7 mm.; wing 7 mm. 



Habitat : Olympia, Wash., seventeen males. (Kincaid.) Type

Eriocera gibbosa, sp. nov. (PI. VIII, fig. 10.) 



Dark brown ; head with a grayish bloom ; frontal gibbosity large ; rostrum yel- 

 lowish ; palpi black ; antenna; black, first and second segments yellowish brown ; 

 thorax grayish brown with four indistinct brown stripes ; halteres brown ; legs yel- 

 lowish brown ; femora lighter toward the base ; tarsi black ; abdomen black or grayish 

 brown ; forceps of male of same color ; ovipositor ferrugineous ; wings with a 

 brownish tinge ; stigma and veins darker brown ; tip of the auxiliary vein opposite the 

 inner end of the second submarginal cell which is much longer than the first submar- 

 ginal cell ; marginal cross veins at the inner end of the latter ; four posterior cells ; 

 discal cell short ; posterior cross vein near its inner end. Length, male 10 mm. , 

 female 12 mm.; wing II mm. 



Habitat: Michigan, two males, one female. (Aldrich.) Type

Eriocera velveta, sp. nov. (PI. VIII, fig. 11.) 



Brown ; head grayish brown ; rostrum, palpi and antennoe brown, basal joint of 

 latter lighter ; thorax grayish brown ; dorsum with six stripes, the lateral pair low 

 down on the lateral margins ; the pleura sometimes with brownish spots where the 

 gray bloom has been rubbed off; halteres brown ; legs brown ; basal two thirds of 

 femora reddish brown ; abdomen and forceps of male velvety brown ; ovipositor fer- 

 rugineous ; wings with a brownish tinge ; stigma but a little darker ; veins brown ; 

 the subcostal cross vein a short distance before the tip of the auxiliary vein ; the tip 

 of the latter nearly opposite the inner end of the first submarginal cell ; the distance 

 from the marginal cross vein to the inner end of the first submarginal cell about equal 

 to the petiole of this cell ; four posterior cells ; posterior cross vein a little before the 

 middle of the discal cell. Length, male 10 mm., female 13 mm.; wing lO mm. 



Haf^itat : Co\oxa.do, one male, one female. (Morrison.) Type no. 

 135. Wash. Agric. Coll. & S. of S. 



A single specimen from Olympia, Wash., seems to belong to this 

 species, but it is much larger, and darker in every respect and with- 

 out any apparent stripes on the dorsum. It may be a distinct species.
