First abdominal segment without yellow basal spot ; elytra black without 

 discal markings, but with a yellow marginal band beliind the humeri, and 

 two transverse reddish-yellow fasciae near apex, whicli are more or less 

 confluent, punctuation fine, the intervals at least as wide as the striae and 



flattened on top flavomarginata (Gray). 



5. Body robust and triangular, enlarged at base, and very acuminate pos- 

 teriorly G. 



Body more slender and elongate, not triangular; elytra more parallel and not 



as strongly acuminate posteriorly 8. 



G. Sutural margin expanded and smooth on Itasal half; elytra without red 

 apical spot 7. 



Sutural margin not expanded on basal half; elytra with a fiery red apical 

 spot cnienta (Olivier). 



7. Broadly triangular : elytra one and one-half times as long as the width at 



base, the maculation consisting of numerous small irregular yellow spots. 



which are confluent pulcherrima Jacquelis Duval. 



More elongate-triangular; elytra two times as long as the width at base, the 

 maculation consisting of a yellow .scutellar spot, and four irregular trans- 

 verse yellow fasciae, which are more or less interrupted.

ACMAEODERA SUBCYLINDRICA, new species 



Narrowly elongate, siibcylinclrical, strongly convex, broadly 

 rounded in front and strongly attenuate behind; when viewed in 

 profile, the surface beneath is nearly straight to the last ventral seg- 

 ment, where it is strongly attenuate, above feebly arcuate; piceous, 

 with a strong purplish tinge; pronotum with an oval yellow spot on 

 each side, narrowly separated from the lateral margin but not attain- 

 ing the base or apex. Each elytron ornated with ten small irregu- 

 lar yellow spots arranged in two longitudinal rows, one along the 

 lateral margin, the other on the disk; in the lateral row the spots 

 are arranged as follows : a very small one at liumeral angle, one just 

 behind the humeri, third at the middle, fourth at apical third, fifth 

 at apical fourth, and a small one at the apex ; in the discal row they 

 are arranged, one at the base, second at basal third midway between 

 the second and third lateral spots, third behind the middle between 

 the third and fourth lateral spots, and a very small spot connected 

 externally to the fiftli marginal spot. Color beneath similar to that 

 above. 



Head feebly convex, with a broad, oval, obsolete depression on the 

 front and a short distinct elevated carina on the occiput; surface 

 densely and very coarsely punctate, the punctures rather shallow, 

 irregular, and nearly confluent, the sides forming a network of po- 

 lygonial areas, bottom of punctures nearly smooth and from which 

 arises a moderately long erect inconspicuous hair; epistoma very 

 broadly arcuately emarginate in front. Antennae serrate from the
