geminatus; in collections containing (:<z/?<r^/;/z<tj, which is not very common, 

 that species is labelled colon ; and all o^^x% geminatus, without regard to 

 the colour of the elytral spot, and again that is labelled geminatus and all 

 others colon. 



L. CAPUCiNUS, Schall., altemans, Casey. — Length, -id-. AS "''ch. 

 Habitat — Michigan, New Hampshire, Maine. 



Black, apterous, form robust, vestiture variable. Rostrum stout, longer than the 

 thorax, sulcate on each side of the carina which attains the frontal fovea or not, closely, 

 unevenly, partly confluently punctured ; scape of the antenns; attaining the eye or not, 

 the first and second joints subequal in some examples, the second much longer in others, 

 probably sexual difterences. Thorax transverse, wider than long, sides parallel to 

 apical third, then rapidly rounding to apical constriction, apex one-fourth narrower 

 than base ; sub-convex, surface even, a slight depression in front of scutellum, closely 

 covered with granuloid tuberculations small on the disk, larger and rugous on the 

 sides ; median carina fine, mostly attaining the base Elytra oval, in general one-half 

 longer than wide, two-thirds to three-fourths wider than thorax ; striate, stria; 

 obscured by the vestiture, but when denuded, deep and narrow, with a row of punctures 

 in the bottom ; intervals either regular and evenly spaced or irregular with the first and 

 third wider, the others perceptibly narrower and slightly furrowed along the middle ; 

 the granuloid tubercles vary from excessively fine to moderately coarse ; apices con- 

 jointly rounded. The anterior femora in the male have the tibial sinuation rectangu- 

 larly laminate on the upper side, and usually the middle and posterior ; mesosternum 

 elevated between the coxae. The vestiture is variable, but mostly of gray and whitish 

 elongate scales evenly intermixed, sparse, not concealing the black surface, the usual 

 median spot on the elytra absent, but a white one on each apical protuberance, the 

 abdominal spots wanting or only traceable in a few denser white hairs. In an example 

 from New Hampshire the vestiture is mottled and denser, the abdominal and median 

 elytral spots present. 



In the European examples seen (all males) there are no abdominal 

 nor median elytral spots, and the vestiture is that first described. 

 The fuller description of the present species, with more ample material 

 than that of Mr. Casey, has reduced the alleged differences between this 

 and Canadensis, Casey, to this : Striae not distinctly punctured, Cana- 

 densis; striae distinctly punctured, capucinus (alternans). This seems to 

 be too small a difference, all other things being equal, on which to base a 

 species, especially in a genus where the individual characters are so 

 instable. 



Lepyrus perforatus, Casey. — While this species in form is similar 

 to palustris, and with the same form of ornamentation, yet it is struc- 

 turally different ; the femoral sinuation is gradually rounded, not spinose 

 as in palustris, nor angulate as in capucima ; the mesosternum is sub- 

 elevated, not flat as in the former, nor so prominent as in the latter. 

 The general vestiture is very short and sparse, not concealing the tuber- 

 cular rugosities and variously tessellate with minute, denser, pale scales ; 

 the elytra and under side are covered with distant, small, polished black
