AMERICAN COLEOPTERA. Ill 



Occurs in the Middle and Southern States to Texas. I have seen one 



in Mr. Ulke's cabinet from California. 



A. flu Yiuianu Gory. — Narrowly cuneiform. Front convex, finely reticulate. 

 Thorax broader than long, narrower posteriorly, apex Insinuate, sides feebly arcu- 

 ate, hind angles rectangular, disc moderately convex, very regularly reticulate, 

 a vague impression each side of middle, another more distinct in front of scutellum. 

 Elytra narrowed to apex, a fine transverse basilar impression, surface slightly 

 rugous, vaguely striato-punctate, with one interval slightly more convex, apices 

 obtuse. Thorax beneath reticulate, body and abdomen obsoletely reticulate or 

 nearly smooth, the last ventral segment very coarsely punctured. Tarsal claws 

 slender. Length .12 — .20 inch; 3—5 mm. 



The male is more slender and smaller than the female. In the latter 

 the last ventral segment is coarsely punctured over its entire surface 

 while in the male the tip is alone punctured. 



The color of this species varies considerably. The head is usually 

 metallic-green, varying to purplish. The thorax is broadly purple-black 

 or dark brown at middle, the sides green or blue. The elytra are dark 

 purple or bronze varying to greenish, with usually a basal triangle of 

 green. The under side is green or bronze. 



Occurs in the Middle and Southern States as far as Texas. 



V ! NOltilll'IS Lee. 

 This genus differs remarkably not only from the other two of the 

 group but from all others in the family in the structure of the antennae 

 of the male. The joints of the male antennae from the second to the 

 tenth are provided with a branch of varying length, that of the second 

 shortest. In the accompanying plate (IV, fig. 9), I have endeavored to 

 reproduce as accurately as possible the form of each joint and its branch, 

 and will refer the reader there rather than give a detailed description. 

 The antennae of the female do not differ remarkably from the usual 

 Buprestide type, being slender and subserrate from the fifth joint. 



X. Brendoli Lee. Proc. Acad. 1866, 384. 



In the two outline figures on the plate (TV, figs. 7, 8), representing 

 both sexes it will be observed that the thorax of the male is quadrate, 

 and that of the female distinctly wider than long. In the latter sex 

 the head is also more transverse and the eyes smaller than in the male 

 and much less prominent. 



The three specimens known do not vary perceptibly from each other 

 in size .20 inch ; 5 mm. 



While very rare the species has a wide distribution. The specimen 

 in Mr. Ulke's cabinet was collected in Peoria, Illinois ; Dr. 'LeConte has 

 one from Texas ; that in my cabinet (a 9 )> was found by Mr. A. Merkel 

 in his garden at Brooklyn.
