ART. 6 NEW BUPRESTID BEETLES FEOM COSTA RICA FISHER 9 



cupreous red, except the basal third, which is bright green; elytra 

 bluish black, and ornamented with yellowish white pubescent de- 

 signs; beneath piceous, with a vague aeneous or cupreous reflection, 

 and more shining than above. 



Head with the front rather narrow, about equal in width at top 

 and bottom, the lateral margins nearly parallel, and with a large, 

 round, deep depression behind the epistoma; surface nearly glabrous, 

 coarsely, irregidarly rugose, and finely, sparsely punctate between 

 the rugae; epistoma transverse between the antennae, and very 

 broadly arcuately emarginate in front; antennae extending nearly 

 to base of pronotum, serrate from the fourth joint, and the outer 

 joints longer than wide; eyes large, broadly oblong, and slightly 

 more acutely rounded beneath than above, 



Pronotum only vaguely wider than long, wider at apex than base, 

 and widest near middle; sides feebly arcuately rounded from apical 

 angles to posterior angles, which are rectangular ; when viewed from 

 the side the marginal carina is straight, the submarginal carina 

 strongly bisinuate, the two carinae narrowly separated anteriorly, 

 and connected to each other behind the middle; anterior margin 

 strongly sinuate, the median lobe strongly produced and broadly 

 rounded; base feebly emarginate at middle of each elytron, the 

 median lobe feebly produced, and broadly subtruncate in front of 

 scutellum ; disk strongly convex anteriorly, broadly transversely con- 

 cave on basal half, the concavity extending narrowly along the lat- 

 eral margins to apical angles, a small round depression near poste- 

 rior angles, and without prehumeral carinae; surface obsoletely 

 granulose, finely but not closely rugose, the rugae more or less con- 

 centrical anteriorly, transverse on basal half, finely, sparsely punctate 

 between the rugae, and with a few short hairs near posterior angles. 

 Scutellum strongly, transversely carinate, and the surface finely 

 reticulate. 



Elytra wider than pronotum at base, and distinctly wider at base 

 than behind middle; sides feebly arcuately rounded for a short dis- 

 tance behind base, broadly arcuately constricted in front of middle, 

 broadly arcuately expanded behind the middle, then strongly 

 obliquely narrowed to the tips, which are conjointly angularly emar- 

 ginate, and strongly serrulate; disk with a rather broad, elongate 

 depression along sutural margins in front of middle, sutural margins 

 feebly elevated posteriorly, and with broad, deep basal depressions; 

 surface densely, coarsely imbricate-punctate, sparsely clothed with 

 short inconspicuous hairs, and each elytron ornamented with yel- 

 lowish white pubescent designs as follows: A small spot in basal 

 depression, a broad vitta along sutural margin extending from basal 

 fourth to middle, where it is expanded transversely, but not reaching 

 the lateral margin, and the apical fourth sparsely clothed with simi-
