NORTH AMERICAN COLKOPTKRA. 11 



striate, strisB creiiiitely punctured, intervals Hat, with extremely fine sparsely 

 placed punctures. Body beneath very sparsely punctate ; posterior femora sparsely 

 l)iinctate, with a series of three or four punctures near the knee. First joint of 

 hind tarsus as long as the next two. Length .18-.20 inch ; 4.5-5 mm. 



Ill the male the spur of the anterior tihite is stouter and more 

 curved and the posterior femora liave more numerous punctures. 



This species is notable l)y its short robust form resembling some of 

 our species of ^Egialia. 



Occurs from Florida to Texas. 



A. l>i<leilS Lee. — Oblong oval, convex, black, shining, elytra and legs red, 

 these paler, anterior angles of thorax paler. Anteunse ferruginous. Head 

 sparsely, rather finely punctate. Clypeus hemihexagonal, broadly emarginate 

 in front and on each side sharply angulate, gente prominent, but obtuse. Thorax 

 convex, black, shining, the anterior angles paler, sides parallel ])osteriorly, arcuate 

 in front, hind angles very obtusely rounded, base slightly sinuate on each side, 

 disc sparsely rather finely punctate, the punctures equally dis]iosed, but some- 

 what uneiiual in size. Elytra slightly narrower at base than the thorax, the 

 humeri distinct, but obtuse, disc striate, the punctures rather fine and not serrate, 

 intervals slightly convex, with very fine sparse punctures. Body beneath very 

 sparsely punctate; hind femora sparsely punctate. First joint of posterior tar- 

 sus as long as the next three. Length .26-.28 inch ; 6.5-7 mm. 



The two specimens before me are probably females, and show no 

 sexual differences. 



At first glance this species so closely resembles fimetarius in form 

 and color that these two might be readily confused. 



Occurs in CV)loi-ado. The type in my cabinet has no special lo- 

 cality, a second from ^Nlr. E. A. Schwarz was collected at Veta Pass 

 at an elevation of more than 9000 feet. 



A, flnictarius Linn.—Oblong oval, very convex, black, shining, elytra 

 uniformly red. Autennse ferruginous. Head sparsely, rather finely punctulate, 

 somewhat rugulose in front, vertex trituberculate, the middle tubercle stronger. 

 Clypeus hemihexagonal with a feebly elevated transverse carina, angles broadly 

 rounded, at middle broadly but feebly emarginate. the sides oblique, slightly 

 sinuate, gense feebly pi-ominent and very obtuse. Thorax transver.se and very 

 convex, black, shining, the front angles with large reddish yellow space, surface 

 with coarse, very irregularly placed punctures with finei- punctures in the inter- 

 vals, sides arcuate, hind angles broadly rounded, base slightly sinuate each side. 

 Elytra as wide as the thorax, the humeri obtuse, disc striate, stria>. crenately 

 punctured, the intervals slightly convex with few fine punctures. Body beneath 

 sparsely punctate, densely at the sides of metasternum. Legs dark reddish 

 brown, tarsi paler. Posterior femora sparsely punctate, a row of coarser punc- 

 tures near the knee. First joint of hind tarsus equal to the next three. Length 

 .26-.34 inch ; 6.5-8.5 mm. 



Jlfa^e.— Frontal tubercles more developed, the intermediate subcornute. Tho- 

 rax more convex, impressed in front. Anterior tibial spur stout and curved. 

 uiiper spur of middle tibia less than half the length of the lower and stout.
