NEW BUPRESTID BEETLES — FISHER 339 



cas long as following three segments united; segments 2-4 globose; seg- 

 ments 5-10 wider, compact, scarcely triangular; slightly wider than 

 long; segment 11 oval. 



Pronotum nearly twice as wide as long, distinctly narrower at apex 

 than at base, widest along basal half ; sides parallel along basal halves, 

 strongly, arcuately converging anteriorly, with the margins narrow, 

 but not visible from above ; disk moderately convex, narrowly, trans- 

 versely flattened along anterior margin, with a broad, shallow, triangu- 

 lar, median depression on basal half, a broad, oblique depression on each 

 side extending forward from base to middle near lateral margin, and 

 trifoveolate along base; surface coarsely, deeply, densely punctate at 

 middle, coarsely, confluently alveolate-punctate toward sides, and 

 sparsely clothed with long, rather broad, erect, whitish hairs. 



Elytra moderately convex, deeply, transversely depressed along base 

 at middle, at base subequal in width to pronotum at base ; sides nearly 

 parallel along basal halves, then arcuately converging to the tips, which 

 are conjointly broadly rounded; lateral margins, coarsely, serrate be- 

 hind middles. Surface striately punctate, striae deeply impressed 

 posteriorly, the punctures in the striae large, separated from one an- 

 other by about one-half their own widths ; interstrial spaces on sutural 

 regions flat, and from one-half as wide to nearly as wide as the strial 

 punctures, wider, strongly convex, and more or less interrupted to- 

 ward sides, rather densely, finely, regularly punctate, with a short, 

 rather broad, erect, white hair arising from each puncture. 



Abdomen beneath rather sparsely, uniformly, finely, shallowly punc- 

 tate on basal sternites, ocellate-punctate on apical sternites, sparsely 

 clothed with short, rather broad, semierect, white hairs; intervals 

 smooth ; last visible sternite broadly rounded at apex, without a sub- 

 apical carina. Prosternum coarsely, sparsely, deeply punctate at 

 middle, coarsely ocellate-punctate at sides, sparsely clothed with short, 

 rather broad, erect, white hairs ; anterior margin sinuate, with two 

 distinct, ohtusely rounded, slightly produced lobes near middle. 



Length 7 mm., width 2.5 mm. 



Tyfe locality. — Puente de Ixtla, Morelos, Mexico. 



T'y^e.—U.S.N.M. No. 58791. 



Described from a single specimen collected by H. F. Wickham. 



This species belongs to Horn's Sinuatae group. It resembles Ac- 

 maeodera tubulus Fabricius very closely, but it differs from that species 

 in having the anterior margin of the prosternum slightly lobed on each 

 side of the middle, the pronotum obliquely depressed on each side with 

 the sides parallel behind the middle, the strial punctures on the elytra 

 coarse, and the interstrial spaces on the sutural regions about as wide 

 as the strial punctures.
