NORTH AMERICAN COLEOPTERA. 115 



This species seems strictly southern in its distribution, occurring 

 from Virginia to Florida and Texas. 



47. C seitula Gory. — Form rather elongate, moderately convex, color deep 

 violet, or dark cupreous, the thorax often more decidedly blue, each elytron with 

 three more brilliant spots, blue or green, and of variable distinctness and ex- 

 tent; antennse gradually more slender to tip, piceous, three basal joints greenish 

 % or cupreous 9- third joint nearly as long as the next three; front slightly 

 convex, green % , violaceous 9 1 coarsely and deeply punctured, an arcuate line, 

 the concavity upward, above which is a slight depression in both sexes ; clypeus 

 (23.3) with a small triangular emargination at middle, subtruncate each side; 

 thorax one and a half times as wide as long, the sides straight, very slightly con- 

 vergent posteriorly, rounded near the front angles, the hind angles distinct and 

 sometimes slightly everted; disc convex, without depressions or callosities, sur- 

 face coarsely jiunctured, sparsely at middle, more densely near the sides, some- 

 times slightly transversely strigose ; elytra wider than the thorax, humeri 

 rounded, sides slightly wider behind the middle, arcuately narrowed at apical 

 third, the margin finely serrate, the apices obtuse ; disc convex, the punctuation 

 coarse, deep, but not dense, there is no trace of costpe and the fovese are scarcely 

 impressed, the basal even rather shallow, the colored spots are placed in the usual 

 position of the fovefe of the other species ; body beneath violet-blue, punctuation 

 coarse, but sparse, the ventral segments without umbones, their angles not promi- 

 nent ; presternum distinctly lobed in front ; anterior femur with rather strong 

 tooth, obsoletely serrate or simple ; last ventral with entire margin. Length 

 .22 - .28 inch ; 5.5 - 7 mm. ( Fig. 232. ) 



Male. — Presternum flat, densely punctured, not pubescent; anterior tibia (2.36) 

 arcuate, a slight dilatation near the tip ; middle tibia feebly arcuate, the posterior 

 straight ; last ventral (234) with a very shallow, broad emargination ; last dorsal 

 very coarsely punctured, entire at apex. 



Female. — Prosternum as in the male ; anterior tibia slightly arcuate, the middle 

 and posterior straight; last ventral (235) sinuately truncate, the angles promi- 

 nent ; last dorsal coarsely punctured, entire. 



This species appears in the monograph of Laporte and Gory as 

 vltramarina Say. Dr. LeConte recognizing the erroneous determi- 

 nation pro])osed the name azurea for it (Proc. Acad. 1857, p. 8), and 

 in his " Revision of the Buprestidse" (Trans. Am. Philos. Soc. xi, 

 1859, p. 288) the name concinnula Lee. is substituted and azurea used 

 for another species. Later, in the " Check List," Crotch used the 

 name chlorocepha/a. During his visit to Europe Dr. LeConte exam- 

 ined many of the types of Gory and Laporte in the possession of 

 Count Mniszech, and obtained a specimen of scitula, which proves to 

 be merely a more brilliantly colored variety of uUramarina % Gr. 

 and L., and concinnufa Lee. I have for these reasons adopted the 

 name scitula as the prior name. 



The more brightly colored specimens resemble both azurea and 

 somewhat Harrml, but the form of the thorax is quite characteristic,
