sometimes reaches the vertex ; scrobe feebly arcuate, usually obso- 

 lescent at about basal third of rostrum ; funicular segments i and 2 

 subequal or i longer, 4, 5, and 6 submoniliform, 7 a little wider than 

 long. Prothorax one-seventh to one- fourth broader than long, wider 

 at base than at apex, widest in front of middle, side margins irregu- 

 larly scalloped and nearly straight and convergent to base, shallowly 

 constricted toward apex, the constricting line rather deeply impressed 

 behind the strong ocular lobe and across the prosternum ; pronotal 

 tubercles or granules coarse for this group, some of them partially 

 coalescent, normally nearly covered by scales, those on disk often 

 bare at summit, each with a puncture and seta at summit. Elytra with 

 rows of coarse serial punctures each nearly closed by a subcircular 

 scale; costae distinct, that on sutural interval at top of declivity most 

 prominent ; declivity in profile perpendicular in female, oblique in 

 male. Beneath and legs setose and densely scaly. Ventral edge of 

 hind tibia nearly straight, clothed with hairs and stiff setae, but with- 

 out coarse spines. Fifth sternitc of (^, as usual in the genus, longer 

 and more broadly rounded at apex. A short length of metepisternal 

 suture visible opposite rear coxa. 



Type locality. — Electron, Wash., W. W. Baker, collector, Truck 

 Crop no. 4971 ; 64 specimens, mostly taken during June 1933, a few 

 in September and October. 



Other locality. — Montesano, Wash., March 30, 1932. W. W. Baker, 

 I specimen. Mr. Baker states, in litt.. that this specimen may have 

 been washed down from the vicinity of Electron.

Closest to ovalis Pierce from Alberta, but that species has three 

 distinct rostral carinae, the median strong throughout, the space 

 between median and lateral carinae groovelike, the seventh funicular 

 segment strongly transverse, the pronotal tubercles more numerous 

 but smaller, the antenna! scape not reaching middle of eye, and the 

 alternate elytral intervals more feebly elevated. The elytral costae of 

 bakeri, on the average, are at least as prominent as in any other 

 Noniidns. The uniform dark brown color of ovalis, as previously 

 recorded by the writer, was tlic result of di-scoloration ; the type 

 specimen, recently cleaned, proves to l)e light brown on the disk of 

 the pronotum and elytra, paler at the sides.
