From the above table I have rejected basalis, dimidiata and canescens, 

 as they are Mexican, and are very rarely found in Texas or Arizona. The 

 species described by Say as Cetonia vestita is believed to be C. hirtclla 

 Linn. (Schaum, Am. Ent. Soc. Fr., 1849, p. 267), and nothing has ever 

 been found since in our country which will fill the description, it is there- 

 fore dropped into European synonymy. 



E. areata Fab. 



Black, moderately shining, elytra luteous with black spaces at the hu- 

 meri, and subapical Umbone and along the suture, upper surface with short 

 erect yellowish pubescence, longer on the head, denser on the thorax and 

 very sparse on the elytra, beneath hairs long and sparse. Clypeus short, 

 narrowed in front, epiadridentate, the middle teeth closer and arising from 

 a common base. Thorax oval, base arcuate entire, surface densely punc- 

 tured. Elytra very obsoletely bicostate, the punctuation very indistinct. 

 Mesosternnm feebly prominent, the protuberance transverse. Pygidium 

 usually moderately, densely punctured. Abdomen with very few punc- 

 tures. Length .48 inch ; 12 mm. 



The club of the male antenna? is a little longer than that 

 of the female. The anterior tibi?e are tridentate in both 

 sexes. 



The normal form of coloration, and which is almost inva- 

 riable in the eastern specimens, is that in which the elytra 

 are in great part luteous, with the base narrowly black, 

 the suture is also black, this color dilating into a large cir- 

 cum-scutellar patch, a smaller transverse space behind the 

 middle, and again dilating at apex. In the specimens from 

 Kansas and Nebraska, the elytra are more roughly sculp- 

 tured and almost entirely black, the luteous color being re- 

 duced to a U-shaped mark by the extension of the elytral 

 black spacer, and by the margin being dark. 



A specimen in Mr. Ulke's cabinet requires special men- 

 tion. It is of the size of aestuosa, the humeri and subapical 

 umbone are similarly tipped with piceous, and the suture 

 very narrowly piceous, disconnected from the suture and 

 along the region occupied by the faint costal are irregular 

 small piceous patches. The sides of the thorax are irregu- 

 larly bordered with a whitish coating, and the pygidium
