406 MEMOIRS ON THE COLEOPTERA 



Frontal impressions shallow and diffuse; eyes very large, at less than a 

 third their length from the nuchal constriction 7 



5 Eyes moderately large as in the preceding species, separated by more 

 than half their length from the constriction. Body moderately 

 stout and fusoid, piceous-black, the head and pronotum deep black, 

 the elytra dark red-brown, the abdomen blackish, the apices of the 

 segments finely paler; head moderate, orbicular, all the regular foveae 

 very large and deep; antennae blackish, the outer joints wider than 

 long; prothorax nearly as in marginalis but rather less transverse, 

 the three punctures of the anterior series coarse; elytra distinctly 

 longer and a little wider than the prothorax, with slightly diverging 

 sides and fully as long as wide as in marginalis, but with the punc- 

 tures stronger, more than twice as numerous and more even in 

 distribution; abdomen finely, rather densely punctate; notch at the 

 ventral apex (cf) very small and shallow, obtuse; hind tarsi shorter 

 than the tibiae. Length (cf 9 ) 5.5-6.7 mm.; width 1.2-1.3 mm.

Eyes large, at much less than half their length from the constriction. .6 



6 Body subparallel, rather convex, shining, piceous-black, the head 

 black, the elytra strongly aeneous; head orbicular, the eyes at a third 

 their length from the constriction, the foveae moderate, the postero- 

 juxtocular very close to the margin of the eye; antennae moderate, 

 not very incrassate, piceo-rufous in color, paler at base; prothorax 

 slightly transverse, moderately rounded at the sides and anteriorly 

 narrowed; elytra ample, fully as long as wide, with barely diverging 

 sides, at base fully as wide as the prothorax, at apex wider; punctures 

 evenly distributed, strong and everywhere rather widely separated; 

 abdomen finely, closely punctate, the segmental apices pallescent; 

 hind tarsi distinctly shorter than the tibiae. Length (9 ) 5.2 mm.; 

 width 1.15 mm. Manitoba (Aweme), Criddle agnatus n. sp. 



Body elongate-fusiform, with very much smaller head, shining, black, 

 the elytra aeneous, the legs testaceous; antennae blackish throughout, 

 not pale at base; head relatively smaller than in any other species, 

 orbicular, barely two-thirds as wide as the prothorax, the eyes at 

 two-fifths their length from the constriction, the postero-juxtocular 

 puncture very coarse and rather close to the eye; antennae moderate, 

 not very incrassate; prothorax nearly as long as wide, widest near 

 the base, the sides thence moderately converging and rather feebly 

 arcuate to the apex, the base circularly rounded; three anterior 

 punctures normal and in straight line; elytra large, rather longer 

 than wide, at base fully as wide as the prothorax and thence gradu- 

 ally wider posteriorly; punctures very fine, even, rather well separ- 

 ated; abdomen gradually tapering, finely and somewhat unevenly 

 punctate, the punctures denser toward the segmental bases; sixth 

 ventral (cf) with a small shallow apical sinus and adjoining smooth 

 triangular impression; hind tarsi very slender, slightly shorter than 

 the tibiae. Length (cf 9 ) 5.0-6.0 mm.; width 0.95-1.1 mm. Vir- 

 ginia (Hampton Roads) and New Jersey (Atlantic City). Eight 

 examples virginicus n. sp.
