are strongly swollen and angulate above bej'ond the middle, the 

 apical slope of the angle nearly straight in profile and minutely 

 irregular or subserrulate. In the female these femora are more 

 clavate than the other four but are simple, and in that sex the 

 antennae are a little shorter but nearly similar, except that the 

 fifth and sixth joints are distinctly thicker than the two preced- 

 ing. In general form of the body and outline of the elytra the 

 two sexes ai'e almost exactly similar. The head seems to be rela- 

 tively smaller in some females than in others. 



This species, while allied to 'perforatum, differs conspicuously 

 in its more dilated hind body and perceptibly less coarse and 

 somewhat sparser punctures, also in its shorter, more fulvous and 

 more recurved pubescence of the elytra, much more irregular sub- 

 basal fovese of the pronotum, color and other characters. In the 

 series of eight specimens before me the largest and smallest indi- 

 viduals are both females. The single example from Ottawa, com- 

 municated by Mr. W. H. Harrington, has the elytra more elon- 

 gate, but does not appear to diflfer much otherwise; it is pale 

 testaceous throughout, as however are several of the Pennsyl- 

 vania specimens. The Virginia representatives have the pro- 

 thorax rather more inflated anteriorly. 



3. S. conjux n. sp. — Moderately stout, polished, impunctate anteriorly, 

 the elytra strongly but sparsely and not very coarsely punctate ; body piceous- 

 black, the elytra slightly paler and rufescent, the abdomen slightly paler at 

 apex ; legs and antennae rufo-testaceous ; pubescence moderately abundant, 

 rather long coarse pale semi-erect and recurved on the elytra, shorter and less 

 conspicuous anteriorly. Head much wider than long, the eyes rather well de- 

 veloped, convex, longer than the tempora. Antennse a little less than J^ as 

 long as the body, gradually incrassate toward tip ; second joint as long as the 

 first but thinner, feebly obconic, 3^ longer than wide, only slightly longer 

 than the third but obviously thicker ; third and fourth narrowest, cylindric, 

 equal in width, % and }^ longer than wide ; fifth and sixth just visibly 

 thicker, ^ and % longer than wide ; seventh nearly % thicker, suboval, 

 as wide as long, very nearly as wide as the eighth, which is more than 

 3^ wider than long and conic at apex ; ninth and tenth almost exactly equal, 

 fully % wider than the eighth, strongly obtrapezoidal and transverse, nearly 

 % wider than long ; eleventh about as long as the two preceding and not 

 wider, obliquely and acutely pointed. Prothorax not quite as long as wide, ^ 

 wider than the head, only moderately inflated and rounded laterally toward 

 apex, the sides feebly convergent but distinctly sinuate toward base ; four 

 subbasal foveae isolated and not jointed by impressions but irregular in form, 

 the irregular cluster at the sides deep. Elytra suboblong-oval, % longer than
