piece ; interspace smooth, shining with a few punctures at base and below the 

 margins. 



Hind coxal plates with small, evenly placed, not deep punctures ; apices 

 rounded, feebly subangulate when viewed from the side. 



Posterior legs with the thighs pale, color of under side, with the knees, 

 and apex of tibia, darker. 



Last abdominal segment shining, very finely rugose. 



Male with the tarsi of front and middle legs thickened, but not produced. 



Male and female types from Winnipeg Beach, Manitoba (J. B. 

 Wallis), are in my collection. Also taken by Mr. N. Criddle at 

 Aweme, Man. Our largest species and at a glance distinct from any 

 other so far known. 



The very black, closely placed punctures give it a very dark ap- 

 pearance. 



Its form places it near the callosus of Leconte. 



Peltodytes lengi new species. 



Oblong oval, greenish yellow, spots moderate in size. 



Size: length 4 mm.; width 2^ mm. 



Head narrow and finely punctate between the eyes, ^■ertex broadly impunc- 

 tate ; eyes large, broadly oval ; antennae color of head. 



Pronotum finely, closely punctured apically, more coarsely and sparsely 

 basally and at the sides ; basal spots large and coarsely punctured. 



Elytra broadest at shoulders, gradually narrowing to the exterior apical 

 angle ; apices feebly sulcate ; eleven striate with the fourth greatly inter- 

 rupted ; punctures of striae coarse and deep, those of the first and second 

 smaller, rows distinct to near apex where there are three or four rows of small 

 punctures placed horizontally, punctures blackened ; maculate with six spots 

 moderate in size and forming the usual two triangles with the median spot 

 entirely free from the narrow black suture ; base narrowly black to the 

 humerus, with no evidence of a subhumeral spot or black dash. 



Under side and legs yellow. 



Prosternal process broad at base, strongly constricted between the an- 

 terior coxae : apex half as broad as at base ; sides and apex margined, margin 

 thickened on basal half, somewhat convex between the margins and conflu- 

 ently punctured. 



Mid-metasternum arched, broad, margined ; margins somewhat thickened, 

 or tumid, at the middle coxae and a little convergent behind, extending more 

 than half way to the suture of antecoxal piece ; a few fine punctures between 

 the margins. 



Posterior coxal plates with numerous small, shallow punctures : apices 

 feebly subangulate. 



Posterior femora black basally and at the knees with a broad yellow 

 band between.
