THE CANADIAN ENTOMOLOGIST. 16^ 



Gyascutus, LeConte. 

 G. juniperimts, n. sp. — Gener.il toini of G. obiiteratus, Lee. Colour 

 metallic-purplish, shining, surface ob=iCured by a greenish-yellow pollinose 

 deposit, which becomes whitish on tile sterna and venter, the entire body 

 and legs clothed as well with a fine, sparse, short white pubescence. Head 

 coarsely, unevenly and confluently punctured, epistoma broadly eniargi- 

 nate. Eyes much less oblique than in G. planicosta and G. obiiteratus, 

 so that the face between them, viewed from in front, is about as broad at 

 top as below. Antennae short, not or scarcely attaining the posterior 

 thoracic angles, the second joint proportionately shorter and thicker than 

 in the female of G. obiiteratus. Pronotum about two-thirds as long as 

 wide, convex, irregularly coarsely punctate, the punctuation extensively 

 confluent at the sides and anterior margin. A broad median space is 

 simply irregularly punctate, the punctures well separated. Sides arcuate 

 anteriorly, nearly straight and almost parallel in posterior three-fifths. 

 Base emarginate at middle, sinuate each side ; apex slightly rounding. 

 Hind angles acute, scarcely perceptibly divergent, front angles obtuse. 

 Elytra, across the humeri, slightly wider than the base of the prothorax, 

 scarcely perceptibly narrowed to about three-fifths, thence rapidly to apex, 

 which is emarginate or shortly spinose, side margin serrate near the tii), 

 surface with small, irregular smooth spaces and rather finely punctured, 

 the punctures somewhat regularly serially arranged near the suture, but 

 confused near the sides and tip, where they become extensively (especially 

 transversely) confluent, giving rise to a rugose structure. Prothorax 

 beneath rather coarsely, deeply and confluently punctured, the prosternum 

 between the coxae smooth, highly polished, not sulcate, but with a longi- 

 tudinal row of pitlike punctures. Meso- and metathoracic sidepieces 

 coarsely and confluently punctate, sterna sulcate, smoother near the middle 

 where the punctures become sparser, but deeper. Abdomen rather 

 coarsely rugosely punctured at sides, middle alutaceous between the 

 punctures, which are coarse, but generally well separated. Last ventral 

 subtruncate and somewhat uneven at tip. Legs alutaceous and distinctly 

 strongly punctured to the tips of the tibi?e. Femora and tibiae simple, the 

 anterior tibiie very slightly arcuate, the middle and hind ones practically 

 straight. First joint of hind tarsi as long as the second and third united, 

 claws simple. Length, 11.75 to 13 mm., .47 to .52 inch.
