similar in form but rather more closely punctate, the punctures similarly- 

 uneven in distribution; scutellum nearly similar, cupreous; elytra nearly 

 twice as long as wide, rather coarsely but not quite so densely cribrate, 

 more notably sparsely so toward the suture, the punctures of the series 

 coarse, deep and perforate; sublateral ridge less prominent; under sur 

 face somewhat more strongly and less sparsely punctate, more strongly 

 but not very closely so laterally; male and female apparently with but 

 slight structural differences. Length 18.0-22.0 mm.; width 7.0-7.8 

 mm. North Carolina; also one specimen labeled " Cal. " but no doubt 

 erroneously. [ = bosci Lap.- Gory] apricans Hbst. 



The sublateral ridge of the elytra varies in prominence in this sec- 

 tion very much as in Cypriacis, where it is very strong and imparts a 

 very characteristic facies in such species as lateralis and intricata and 

 feeble in fabulosa and brevis; here it is almost obsolete in decora but 

 pronounced in apricans and especially in the female of cribripennis. 

 This ridge is seldom very prominent in Buprestis proper, though 

 generally traceable. All the species of this section are locally distrib- 

 uted in pine regions and therefore generally rare, though abundant 

 enough within their proper environments, Ultramarina seldom 

 seems to have a coloration wholly warranting its name, the bright 

 surface generally being of a more golden-green color than in decora; 

 it seems to be decidedly rare.

This genus, though so different in general habitus, is related closely 

 to Buprestis in most of its general organization, excepting in antennal 

 structure and the very much shorter basal joint of the hind tarsi; it 

 differs otherwise principally in its rough and irregular surface sculp- 

 ture, prolongation of the elytral apices, which however becomes obso- 

 lete or nearly so in some species and occurs sporadically in other 

 parts of the family, as for instance in Psiloptera and in Buprestis 

 consularis, and, finally, in the male and female characters at the apex 

 of the abdomen, which, though of a markedly different kind, are 

 similarly inconstant within s])ccific limits and therefore unreliable as 

 a specific criterion. The broadly and feebly sinuato-truncate and sub- 

 lobate anterior margin of the prosternum is a rather more striking 

 feature than in Buprestis, but the prosternal process, the mesosternum 

 and the metasternum arc virtually similar and the mcso-metasternal 

 suture is very fine, the two surfaces being similarly anchyloscd and not
