apparently narrower in fmnt, coarsely but sparsely punctured, with few finer 

 punctures intermixed; sides moderately rounded, base not margined. Elytra 

 moderately deeply striate, stria3 closely punctured at base, scarcely punctured 

 at apex, insterstiees moderately convex, sparsely punetulate at apex only. 

 Body beneath piceo-rutbus ; legs rufous. Mesosternum between the coxfc dis- 

 tinctly carinate, in front strigose. Antennre testaceous. Length .16 inch; 

 4 mm. 



Easily known from lividus by its color, coarsely punctured and more 

 convex thorax. 



Specimens collected near St. Augustines, Florida, and presented to 

 me by Mr. Levi Taylor. 



Group I contains but few species easily known among the others 

 by the yellow elytra with variously arranged black spots, and by the 

 tuberculate head. All have the thorax distinctly margined along the 

 basal line. The hind tibiiie are rather stout and fringed at apex, with 

 unequal spinules. The hind tarsi have the first joint equal in length 

 to the longer tibial spur. The sexual characters may be found in the 

 more strongly tuberculate head, and more coarsely punctured 

 thorax. 



Our species are as follows : 



Clypeus distinctly angulate on each side of emargination serval. 



Clypeus broadly rounded on each side. 



Elytra with lateral black vitta inquinatus. 



Elytra with black spots only, no lateral vitta. 



,18 — .22 inch ; California. Elytra with the inner series of 



strise joining the outer series pardalis. 



.28 inch. Canada and Maine. Elytra with the three inner 

 strise nearly equal, not confluent with the outer 

 three leopardus.

A pretty little species easily known by the clypeus being distinctly angulate 

 or broadly denticulate on each side of the emargination. The head is very 

 coarsely punctured, and toward the sides and front rugose, gense not promi- 

 nent. Thorax moderately convex, sides feebly rounded, surface coarsely punc- 

 tured, rather more densely toward the sides, less coarsely and densely in the 

 female. Elytra pale yellowish as in inquinatus, with the lateral and apical 

 margins reddish, and with black spots arranged as follows; a small spot at 

 base of fifth interspace, another on the fourth slightly in front of middle and 

 one slightly behind the latter and usually confluent with it on the third inter- 

 space, sometimes extending on the second, a sinuous band composed of conflu- 

 ent spots on the second, third, fourth and fifth interspaces about one-fourth 

 from the apex, lateral stripe occupying portions of the seventh, eighth and 

 ninth interspaces, gradually fading into the rufous margin. Body beneath 

 brownish, legs paler. Length .18 inch; 4.5 mm. 



The rufous marginal space becomes broader at apex extending 

 about a sixth of the length of the elytra, and usually darker at its an-
