than in the male, which has, especially on the hind tibiae, a 

 dense brush of long hair on the inner side. 



In form, this species hears a resemblance to sepulcralis, 

 hut so (lifters in color and vestiture, not only from this, hut 

 also from all our others, as to make it very conspicuously 

 distinct. 



Occurs in Dodge county, Nebraska. 



E. Kernii Hakl. 



This species has become so generally known as to need no extended de- 

 scription. The clypeus is nearly square, the angles rounded, the anterior 

 margin feebly emarginate. The thorax is transversely oval, base truncate 

 at middle, surface densely and coarsely punctured. The elytra are each 

 rather broadly and deeply bisulcate, the surface sparsely punctate and at 

 the sides transversely wrinkled. The pygidium is concentrically strigose. 

 The mesosternum does not project in a button like protuberance. Length 

 .4C-.52 inch; 10-13 mm. 



The male antennal club is a little longer than that of the 

 female. The anterior tibiae are very decidedly tridentate in 

 the female and either simply bidentate in the male or with 

 the upper tooth showing a very feeble trace. 



Xo species in our fauna exhibits such a wide range of 

 color variation. 



In the normal form the under surface and legs are piccous 

 or black. Head black. Thorax black, sides more widely, 

 base very narrowly bordered with yellow. Elytra in great 

 part yellow or reddish-yellow, maculate with, black spots of 

 irregular size and shape, becoming more or less confluent. 



The first noticeable variety {Clarkii Lee.) has the abdomen, 

 posterior legs and the anterior four tibiae pale reddish-yel- 

 low. The discal black space of the thorax is divided by a 

 pale median stripe, the elytra remaining normal in color. 



Full) - as common as tliis last variety is one in which the 

 entire body above and beneath is black. 



These last forms resemble the species described further- 

 on as devulsa, but this has the base of thorax emarginate. 



Occurs over the region of the Plains from Kansas to 

 Texas.
