longer than the second, joint 8 excised beneath, joints 9 and 10 much 

 smaller, also excised beneath, the ninth indistinctly so, last joint rather 

 long and slender; dorsuluru and mesopleurse with large, rather 

 shallow punctures; mesosternum carinated laterally and anteriorly; 

 epimerum and episteruum mesothoracis distinctly separated ; middle 

 segment posteriorly cicatricose, its enclosure very strongly defined, 

 the stria' coarse and rather irregular ; legs long, tibite and tarsi 

 spinose, fore femora formed into a broad lamina; wings yellowish, 

 including nervures and stigma, submedian cell of posterior wings 

 terminating at the origin of the cubital vein ; abdomen with first 

 segment long and narrow, subpetiolate as in mirandus, apical 

 segments distinctly punctured, last ventral segment bifid. Black; 



antenna' entirely and base of wings 

 rufous; clvpeus, inner and posterior 

 orbits, face below antennae, labrum, 

 mandibles except apex, line on pro- 

 notum, tubercles, long spot behind 

 them, scutellum, postscutellum, spot

 tomentose. Length 11 mm. 



Washington State. Apparently close to gracilis, but differs in the 

 enclosure of middle segment being striated throughout, coarse punct- 

 ures of dorsulum, yellow wings, etc. Handlirsch does not mention 

 the anterior femora in his description of the $ of gracilis, and it is 

 therefore likely that they are not laminate as in mirandus and 

 laminiferus.
