in the sexes, the femora only moderately swollen; prosternum trans- 

 versely, rather finely, not densely and confidently punctate (9), 

 more closely rugose (cf). Length (cf,9) 4-8-6-3 mm.; width 1.6- 

 2.0 mm. Missouri and Indiana to Pennsylvania. [Callidium

 A Similar to the preceding in form, coloration and sculpture but very 

 much larger, the antennae with more elongate joints though simi- 

 larly as long as the body (cf ), and with a notably stouter basal 

 joint; prothorax more broadly rounded at the sides and less prom- 

 inent behind the middle, where however it is likewise widest; 

 legs differing greatly, long, with large and very stout femora (cf), 

 or notably small, with very moderate femora (9); prosternum 

 finely, closely rugose in the former, or finely, remotely punctate 

 (9). Length (cf,9) 7.0-7.8 mm.; width 2.4-2.6 mm. New 



York hudsonicus n. subsp. 



3 Legs wholly testaceous. Form elongate, rufo-testaceous, with short 

 sparse pallid pubescence; prothorax slightly shorter than wide, 

 anteriorly somewhat, posteriorly distinctly, constricted, the sides 

 rounded, sparsely punctate; elytra dark blue, densely punctate; 

 abdomen nigrescent; antennae obscure rufous at base. Length 6.3 

 mm. California (Tejon). [Callidium blandum Lee., Proc. Acad. 



Phila., 1859, p. 79] blandus Lee. 



Legs deep black, the tibiae and tarsi feebly picescent. Form narrow, con- 

 vex, strongly shining, deep black throughout, the prothorax above 

 and beneath alone paler and testaceous, the pronotum nubilously 

 bordered with black at apex and base toward the middle; pubes- 

 cence everywhere extremely short, inconspicuous; head finely but 

 strongly, not densely punctate, the eyes very far from divided, the 

 notch only penetrating two-thirds across; antennae (cf ) moderately 

 slender, four-fifths as long as the body, blackish, the joints feebly 

 pallescent toward their bases, the second a little more than half as 

 long as the third; prothorax only very little narrower than the elytra, 

 parallel, with very evenly and strongly arcuate sides, nearly as long 

 as wide, the base and apex subequal, the former scarcely at all con- 

 stricted; surface very convex, finely, not densely punctate, with an 

 elongate and smooth, scarcely convex space at each side of the median 

 line, which is narrowly impunctate basally but not tumid; scutellum 

 small, nude, polished; elytra much more than twice as long as wide, 

 parallel, rather obtusely rounded at apex, the punctures not very 

 coarse, impressed, separated by about their own diameters; legs 

 rather short, with moderately but very abruptly clavate femora, not 

 differing much sexually; tarsi very short. Length (cf, 9) 5-3~ 

 5.8 mm.; width 1.3-1.6 mm. New Mexico densipennis n. sp. 



<3Lreus Newm., is now erroneously listed as a Callidium but was 

 correctly assigned to Phymatodes by LeConte in his early studies; 

 it does not seem to merit its name very obviously, as there is no 

 distinct metallic lustre, at any rate in my single male example,
