276 MEMOIRS ON THE COLEOPTERA 



Group I. 

 Phymatodes in sp. 



Our only species assignable to this group is the well known 

 variabilis Linn., of rather large size and very elongate form, intro- 

 duced into the Atlantic regions from Europe through commerical 

 intercourse. 



Group II. 

 Poecilium Fairm. 

 This group may be subdivided into several sections as follows: 



Upper surface uniform in coloration 2 



Upper surface uniform in color, except that the elytra became nubilously 

 paler basally 5 



Upper surface not or but seldom uniform in coloration and having a 

 single pale transverse fascia at the middle of the elytra 6 



Upper surface as in the preceding, except that the elytra have two 

 transverse pale fasciae 7 



2 Prothorax rather loosely and irregularly punctate, generally with 

 confused smooth callous areas 3 



Prothorax densely punctate, without large callous spots 4 



3 Color blackish-brown above, generally without very pronounced 

 aeneous tinge, paler and uniform beneath, the legs still paler and 

 flavate-brown; punctures throughout strong though not very coarse, 

 separated by about their own diameters anteriorly, not quite so 

 strong and two or three times as sparse on the elytra; pubescence 

 everywhere notably long, pallescent; prothorax slightly transverse, 

 obtusely subangulate at the sides just before the middle, narrower 

 at base than at apex; elytra nearly one-half wider than the pro- 

 thorax, parallel, more than twice as long as wide, very obtuse at 

 apex; legs well developed, the femora much dilated in the male. 

 Length (c?) 9-4 mm.; width 2.9 mm. New York. [Callidium 

 cereum Newm., Ent. Mag., V, 1838, p. 393; C. pallipes Hald., 

 Tr. Am. Phil. Soc., X, 1847, p. 37] aereus Newm. 



Color aeneo-piceous, elongate, sparsely pubescent; prothorax shorter 

 than wide, rounded at the sides, punctulate, margined at apex and 

 base; elytra slightly wider than the prothorax, very shining, sparsely 

 punctate; femora strongly clavate; antennae rufescent at base. 

 Length 7.5 mm. Near Fort Vancouver. [P. (eneus Lee., Proc. 

 Acad. Phila., 1854, p. 18] asneus Lee. 



4 Form elongate, fusco-piceous in color, sparsely pubescent; head 

 densely punctulate; prothorax slightly shorter than wide, rounded 

 at the sides, densely punctate, with a smooth median line; elytra 

 rather densely, less finely punctate; abdomen and legs testaceous. 

 Length 10.7 mm. California (Punto de los Reyes). [Callidium 

 infuscatum Lee., Proc. Acad. Phila., 1859, p. 285]. .infuscatus Lee. 



Form nearly similar, larger in size, blackish-brown, not at all shining,
