convex on the disc; elytra parallel to one-third, thence slightly 

 arcuately expanded to near the apex, which is broadly rounded, 

 flattened on the disc. Antennae cf about two-thirds as long, 9 

 about half as long as the body. Length 4.5-6.5 mm. California

juglandis Leng 



The two following generically doubtful species are appended to 

 this group; the descriptions are as originally published. 



Blackish-piceous, finely, sparsely pubescent. Head and prothorax 

 finely, not densely punctured, the latter a little wider than long, 

 rounded at the sides, rufous, with a broad black dorsal stripe. Ely- 

 tra not wider than the prothorax, densely punctured. Beneath 

 sparsely punctulate, prothorax rufous, legs piceous, coxae and thighs 

 (except at base) blackish. Front coxae contiguous; mesosternum 

 triangular, middle coxae slightly separated. Antennae slender, 

 filiform, a little more than half as long as the body, 4th joint equal 

 to 5th. Length 6.3 mm. Lake Superior (Isle Royale). A single 

 specimen. [P. maculicollis Lee., Proc. Am. Phil. Soc., XVII, 

 p. 614] maculicollis Lee. 



Black, very sparsely and finely pubescent, head punctured; prothorax 

 one-half wider than long, strongly punctured, much rounded at the 

 sides; elytra strongly and equally punctured; antennae and legs 

 tinged with piceous, the former slender and about two-thirds as 

 long as the body. Length 6.5 mm. New York (Buffalo). A 

 single specimen. [P. ater Lee., Bull. Bk. Ent. Soc., VII, 1884, p.

Group III. 

 Subgenus Phymatodina nov. 



Greatly resembles the varius decussatus section of the preceding 

 subgenus, but notably different in sculpture and in the very short 

 hind tarsi; there are a number of species and subspecies as follows: 



Elytra dark, but always pale between the anterior fascia and the base. .2 

 Elytra uniformly piceous-black throughout so far as known, excepting 



the white fasciae 4 



2 Legs not differing much in the two sexes. Rather narrow and feebly 

 convex, strongly shining throughout, the punctures throughout 

 bearing rather long fine erect hairs; head blackish; prothorax pale 

 testaceous, infumate anteriorly; elytra pale testaceous, blackish 

 behind the anterior fascia; under surface blackish, the abdomen still 

 darker, the legs and antennae pale; head small, sparsely punctate, 

 the eyes far from divided ; antennae four-fifths as long as the body (cf ) 

 or less than three-fourths ( 9 ), slender, evidently thicker in the male, 

 bristling with long sparse hairs, the second joint nearly half as long 

 as the third; prothorax as long as wide, distinctly narrower than the 

 elytra, strongly and evenly rounded at the sides, convex, with mod-
