rows each side, about as in ovatipennis. Scape scaly and setose, 

 funicular segments in general a little shorter than in ovatipennis, the 

 seventh about as wide as long. Head with a few setae above eye, some 

 of the scales iridescent. Prothorax slightly transverse (about 10-9), 

 apex not constricted ; pronotum with small, scale-covered, setigerous 

 tubercles, those on disk more distinctly isolated than in ovatipennis 

 because of the virtual absence of scales in the groovelike network of 

 the interspaces, the scales on tubercles more or less iridescent. Elytra 

 ovoid, about as in ovatipennis; discal intervals feebly convex, es- 

 pecially laterally, the third and fifth slightly more prominent at base, 

 the suberect setae in a nearly regular row on each discal interval, the 

 serial punctures rather coarse, the serial scales round and not entirely 

 closing the punctures. Beneath scaly and setose, the fifth sternite (5) 

 broadly, faintly impressed and rugosely punctate. Legs as in ovati- 

 pennis, the tibiae denticulate on ventral edge.

Differs from ovatipennis in its very feebly expanded prothorax, 

 the more distinctly isolated pronotal tubercles, and the slightly shorter 

 intermediate segments of the funicle. 



Subgenus PHYMATINUS LeConte 



Phymatinns LeConte, Ann. Mag. Nat. Hist., 1869, p. 382. (Monobasic type, 

 Tyloderes gcmmatus LeConte, Zool. Rep. Expl. and Surv. . . Route . . 

 Miss. . . to Pacific, p. 56, 1857; type locality, Shoalwater Bay, Wash.) 



Specimens of gcmmatus have been examined from various localities 

 in Washington and Oregon. Recorded from California also in Leng 

 catalog. The majority of the specimens seen have at least part of the 

 dorsal scales green, but a few are grayish white with brownish 

 mottlings, and one specimen is predominantly brown above. The 

 rostrum is relatively long, often being at least three times as long as 

 thick at base. 



Panscopus (Phymatinus) sulcirostris Pierce is a synonym of 

 Agasphaerops nigra Horn (see Buchanan, Proc. Ent. Soc. Washing- 

 ton, vol. 29, p. 26, 1927). 



Subgenus NOCHELES LeConte (PANSCOPIDIUS Pierce) 



Nocheles LeConte, Amer. Nat., vol. 8, p. 453, 1874. Though it is evident that 

 LeConte had no intention of founding a new genus at this time, his state- 

 ment " in one specimen of Nocheles but 4 (abdominal segments) are visible" 

 can be considered as establishing the name. The earliest formal description
