except at tip clothed with similar material. The clypeus is 

 formed as in normal areata, and the characters generally arc 

 those of that species. From its appearance it might he sus- 

 pected of heing a hybrid between aestuosa and areata. 



Occurs from the Middle States, westward to Kansas, and 

 south to Texas. 



E. verticalis, n. sp. 



Black, moderately shining, upper surface without pubescence, form 

 robust, moderately convex. Clypeus as long as wide, a little narrowed in 

 front, anteriorly emarginate, the angles acute and reflexed, vertex with an 

 obtuse tubercle, surface of head coarsely, densely and deeply punctured. 

 Thorax oval, narrowed in front, broader than long, sides strongly arcuate, 

 especially in front, base less arcuate, not emarginate, disc moderately con- 

 vex with coarse punctures sparsely placed, but closer near the anterior 

 margin, a narrow smooth median space. Scutellum smooth. Elytra one- 

 half longer than the thorax, disc with rows of ocellate foveae forming 

 nearest the suture two distinct pairs separated by very feeble costre, be- 

 tween the ocellate fovea' -are simple punctures distantly placed, at the siilcs 

 the punctures are irregular, and more densely placed ; sutural angle obtuse. 

 Pygidium sparsely punctate. Body beneath with brownish hair, abdomen 

 nearly smooth, a few coarse punctures at the sides only. Length .52 inch ; 

 13 mm. PI. iv, fig. 12. 



The sexes differ only in the form of the pygidium, that 

 of the male being more convex and innexed at tip. The an- 

 terior tibia? are acutely tridentate, the upper tooth more 

 distant than the other two. The antenna] club is nearly as 

 long as the entire stem in both sexes. The mesosternal 

 button is transversely oval and hairy in front. 



In general form this species resembles areata, but is a 

 little more robust. It is easily known among the species in 

 our fauna by its bidentate clypeus and totally black color, as 

 well as by the elytral sculpture. By its form of clypeus it is 

 allied to E. Hera Burm. from South America. 



Two specimens are before me, one of each sex from Ari- 

 zona, and the adjacent portion of California. 



E. aestuosa, n. sp. 



Piceous, moderately shining, body above luteous, thorax with a large 

 median piceous space, humeral and suhapical umbones of elytra tipped 

 with piceous, form moderately robust, surface above and beneath with 

 short, inconspicuous pubescence. Clypeus a little wider than long, slightly 

 broader in front, angles rounded, anterior margin moderately reflexed and
