ACMAEODERA WICKHAMI, new species 



Acmaeodera eubaecola Wickham, Canad. Entomol., vol. 27, 1895, p. 295 

 (not eubaecola Jacquelin Duval). 



Male. — Rather broadly elongate, feebly triangular, broadly 

 rounded in front, strongly acuminate posteriorly and moderately 

 convex above (feebly sinuate below and broadly arcuate above when 

 viewed in profile) ; head and pronotum aeneous, with a strong cup- 

 reous or purplish tinge, the latter with a large, more or less triangu- 

 lar yellow spot situated on each side along the lateral margin, broader 

 and more elevated posteriorly, not touching the lateral margin, nor 

 extending to the anterior or posterior angles; elytra black, with a 

 purplish, greenish or bluish tinge, and each elytron ornated with 

 yellow markings as follows : A small round spot at humeral angle, a 

 transverse one at base near scutellum, a narrow, irregular transverse 

 fascia at basal fourth, a similar one at middle, a more arcuate one 

 at apical third, and a smaller one near the apex, all of these fasciae 

 are more or less interrupted ; beneath aeneous, with a strong cupreous 

 or purpureous reflection, and more shining than above. 



Head flat, with a short elevated carina on the occiput; surface 

 densely and coarsely punctate, the punctures shallow, more or less 

 confluent, and the sides forming a network of polygonal areas, the 

 bottom of the punctures smooth and with a short erect hair at the 

 middle, the intervals narrow, irregular in shape, smooth and shining 

 on the top ; epistoma broadly and deeply arcuately emarginate in 

 front, forming a broadly rounded lobe on each side of the emargina- 

 tion; antennae serrate from the fifth joint. Pronotum strongly 

 transverse and moderately convex, two and one-third times as wide 

 as long, distinctly narrower in front than behind, widest at base, with 

 an obsolete impression in front of the scutellum, a narrow trans- 

 verse depression along anterior margin, broadly interrupted at the 

 middle, and on each side near the inner margin of the yellow spot, 

 a deep foveate depression situated a short distance from the base, 

 and a broad obsolete depression extending obliquely toward the 

 lateral margin ; sides obliquely and feebly arcuately expanded from 

 anterior margin to the posterior angles, which are rectangular and 

 bent under, the margins narrowly flattened and only visible anteriorly 

 from above; anterior margin strongly arcuately emarginate, with 

 a feebly rounded median lobe; base transversely truncate; surface 

 densely and coarsely punctate, the punctures well separated on the 

 disk, but becoming more or less confluent toward the sides, bottom of 

 punctures finely granulose and from which arises a short, erect in- 

 conspicuous hair, intervals smooth and shining. Elytra strongly 

 convex anteriorly, feebly flattened along suture near apex, slightly 

 wider than pronotum at base, and rectangular at the humeral angles :
