evident punctuation. The striped form, which, for convenience, may 

 be known as subvittata, seems the more abundant, and it is remark- 

 able that it has not received a name. 



Occurs from Massachusetts to Iowa, Georgia and Texas, and in- 

 termediate localities. 



23. CE. sexinaculata Illigc.— Oblong; oval, depressed, uot shining, above 

 reddish yellow, thorax and elj'tra with piceous spots. Antennse sleuder, longer 

 than half the body, yellowish testaceous, third and fourth joints equal. Head 

 reddish yellow, occiput piceous, alutaceous. coarsely sparsely punctate, a short, 

 moderately deep, transverse impression between the eyes, frontal carina obtuse, 

 tubercles not distinct. Thorax twice as wide as long, arcuately, but slightly 

 narrowing to apex, margin widely explanate, anterior angles feebly dentiform, 

 surface alutaceous, coarsely not closely punctate, color reddish yellow with a 

 large brown space each side. Elytra a little wider at base than the thorax, hu- 

 meri obtuse, umbone moderately prominent, smooth, a distinct, rather long 

 sulcus within it and a distinct costa or j)lica extending from the umbone nearly 

 to the apex, margin distinctly explanate, surface coarsely, deeply and moderately 

 closely punctate, color reddish yellow, with piceous or black spots as follows: 

 one at umbone, a second posteriorly near the side margin, a third between these, 

 but near the suture, these are often connected, forming a broad X, behind the 

 middle an irregular transverse fascia, broadest at the suture. Epipleurse pale, 

 broad in the entire length. Prothorax beneath pale. Mesometasternum pice- 

 ous, abdomen reddish, usually darker at middle, surface finely alutaceous, sparsely 

 punctate, with few hairs. Legs rufotestaceous. Length .14 — .16 inch. ; 3.5 — 4 

 mm. Plate VI, fig. 3. 



While this species varies considerably in the extent of its elytral 

 markings it is readily known by the very coarse punctuation of the 

 entire upper surface and the costa which extends from the umbone 

 to near the apex. There is often a second short costa within this 

 near the apex. 



Occurs from the New England States westward to Missouri and 

 south to Florida. 



24. <E. snturalis Fab. — Oblong oval, depressed, feebly shining, pale yellow, 

 base of elytra, suture and spots on each side brown. Antennae longer than half 

 the body, slender, testaceous, thii-d joint very slightly shorter than the fourth. 

 Head yellow in front, vertex and occiput brown, coarsely and sparsely punctate, 

 a deep transverse depression between the eyes, frontal carina short and obtuse, 

 the tubercles smooth. Thorax more than twice as wide as long, sides arcuately 

 narrowed to apex, margin broadly explanate, front angles dentiform, color yel- 

 low, immaculate, alutaceous, sparsely and very indistinctly punctate. Elytra 

 not wider than the thorax, humeri obtuse, umbone moderate, limited within by 

 a distinct sulcu.s, margin distinctly explanate. surface coarsely and moderately 

 closely punctate, smoother at apex, color pale yellow, the base between the um- 

 bones, suture three-fourths to apex, and often two spots on each elytron brown. 

 Epipleurse broad, pale. Body beneath and legs pale. Abdomen shining, sparsely 

 punctate. Length .14— .16 inch.; 3.5 -4 mm. Plate VI, fig. 5.
