186 GEO. H. HORN, M. D. 



at basal half piceous. Body beneath aiul legs reddish yellow, the anterior and 

 middle tibise and tarsi brownish. Abdomen shining, very sparsely punctate. 

 Length .22— ..34 inch. ; 5.5—8.5 mm. Plate V, figs. 1-5. 



This is the largest species in our fauna, and one of the most vari- 

 able. The variations are in form, sculpture and coloration. 



The usual form of this species is oval, usually I'ather broadly, but 

 occasionally oblong. The elytral sculpture may be as coarse and 

 dense as in thoracica, or comparatively smooth. The median vitta 

 is usually equal in width to the yellow on either side of it, but may 

 become broader, and specimens have been seen in which the sutural 

 and median vittse are confluent. A specimen in my cabinet from 

 Georgia has the submarginal vitta extremely narrow, while another 

 from Florida has the median vitta slender and broadly interrupted 

 at middle. The discal spot of the thorax is variable, but never large, 

 and does not often form a transverse band. 



A remarkable variety has been observed, which, for convenience, 

 I call brevilineata (Plate V, fig. 4), in which, with an entirely j^ale 

 margin, the disc is black or slightly bluish, with a short yellow vitta 

 beginning within the humeral umbone. Another variety in the 

 cabinet of Mr. H. A. Kelley has the median vitta almost entirelv 

 obliterated. 



The intrahumeral impression at the base of the elytra is usually 

 feeble, and the punctures in the vicinity not more conspicuous. Two 

 specimens in my cabinet have the depression deep, and from it ))ro- 

 ceed coarse j)unctures extending at least one-fourth the length of the 

 elytra. These also agree in having the submarginal vitta very nar- 

 row. It is quite possible that this vitta may disappear, in which case 

 the sj)ecimens would agree very well with Harold's description of 

 Horni. 



Occurs from North Carolina to Texas. 



12. <E. teiiiiiliiieata n. sp. — Broadly oval, moderately convex, shining, 

 reddish yellow beneath, pale above, elytra with very slender vitta, sutural, me- 

 dian and marginal. Anteunse scarcely half as long as ihe body, piceous. the 

 three basal .joints paler, terminal joint partly %, or entirely yellow 9- Head 

 reddish yellow, smooth at middle, coarsely cribrate at the sines, frontal carina 

 very short and obtuse, tubercles distinct. Thorax more than twice as wide as 

 long, widest at base 9 , or not wider at base than middle % , sides arcuate, mar- 

 gin rather widely explanate, anterior angles distinctly dentiform, surface smooth, 

 shining, with scarcely any evidence of punctures, color pale yellow with faint 

 traces of five darker spots. Elytra scarce y wider than the thorax, the humeri 

 obtuse, uihbone scarcely prominent, a slight impression within it, disc moder-
