that it may be referred to definitely by name in official reports. 

 The species belongs to the verna group of Baryodma, having the 

 mesosternal process narrow and with fine strong medial carina, 

 and it should follow the Colorado species described by me some 

 years ago under the name suffusa (Tr. Acad. Sc. St. Louis, 1906, 

 p. 162). 



Baryodma ontarionis, n. sp. 



Shining black throughout, the legs barely at all paler, 

 the elytra sometimes, but not always, finely, suffusedly 

 reddish at the apical margin internally; pubescence rather 

 short and coarse, not at all close; head orbicular, with 

 evident but sparse punctures, the eyes very moderate 

 in size and not prominent; antennae attaining the base of the 

 prothorax, black, moderately incrassate, the outer joints trans- 

 verse, the last slightly longer than the two preceding combined, 

 the second and third rather long and subequal; prothorax nearly 

 one-half wider than long, widest near the base, which is evenly 

 arcuate, the sides thence feebly converging and moderately 

 arcuate to the apex, the basal angles rounded ; surface evenly and 

 moderately convex, with small, remote and irregularly distributed 

 punctures, more closely aggregated in two widely separated and 

 scarcely at all impressed longitudinal lines along the middle; 

 elytra transverse, barely wider, the suture somewhat shorter, 

 than the prothorax, the punctures rather strong and deep, evenly 

 and not very closely spaced; abdomen paraile\ punctured nearly 

 like the elytra, the first two tergites broadly and rather deeply 

 impressed, the third very obsoletely, the impressions not 

 differently sculptured; tarsi rather short, slender, piceo-rufescent. 

 Length 2.6-4.0 mm; width 0.78-1.2 mm. Ontario (Ottawa) and 

 Quebec (Coaticook). 



This species seems to be rather common, and I have received 

 numerous examples from Mr. Beaulne, besides the series recently 

 sent by Mr. Gibson. It differs from verna and allied species in 

 not having a well defined pale spot near the inner apical angles 

 of the elytra, and from stiff iisa, in its black elytra, less anter- 

 iorly narrowed prothorax and more distinct elytral punctures, 

 besides the less apically incrassate antennae. It does not seem to 

 resemble closely any European species known to me.
