Male. — Broadly elongate, moderately convex above, rather strongly shining, 

 purplish black, and each elytron with five golden-green spots; beneath purplish 

 black, with a faint greenish reflection, more strongly shining than above. 



Head bronzy black in front, becoming bronzy green toward clypeus, and 

 bluish black on occiput, with a narrow, smooth, longitudinal carina on occiput, 

 connected anteriorly to a transversely arcuate carina on vertex; front flat; 

 surface coarsely, deeply, confluently ocellate-punctate, sparsely clothed with 

 short, semierect hairs; clypeus broadly, deeply, angularly emarginate in front, 

 arcuately rounded on each side. Antenna cupreous, slightly bronzy, gradually 

 narrowed to apex ; intermediate segments compact, slightly wider than long, 

 broadly subtruncate at outer margins; third segment subequal in length to 

 following three segments united. 



Pronotum twice as wide as long, wider at base than at apex, widest near 

 apex ; sides obliquely truncated at apical angles, slightly sinuate and obliquely 

 converging from near apical angles to posterior angles ; anterior margin arcu- 

 ately emarginate, with an indistinct, broadly rounded, median lobe ; base 

 arcuately emarginate on each side, median lobe slightly produced, broadly sub- 

 truncate in front of scute! lum ; disk uniformly convex, without depressions or 

 callosities; surface coarsely, deeply, sparsely punctate, more densely punctate 

 at sides, intervals densely granulose. 



Elytra distinctly wider than pronotum, nearly twice as long as wide, widest 

 behind middle ; sides slightly diverging from humeral angles to behind middle, 

 then arcuately converging to tips, which are conjointly broadly rounded ; lateral 

 margins coarsely serrate ; basal depressions broad and deep ; humeral depres- 

 sions obsolete; surface glabrous, without longitudinal costae, rather densely, 

 finely, uniformly punctate, intervals finely granulose, and each elytron with 

 five round, golden-green spots as follows: One in basal depression, a large de- 

 pressed one at middle, one slightly in front of median one at lateral margin, 

 and two situated transversely at apical third. 



Abdomen beneath very coarsely, sparsely punctate, clothed with a few short 

 hairs, without lateral callosities, intervals finely granulose ; last visible sternite 

 broadly, shallowly, arcuately emarginate at apex, without a submarginal ridge, 

 lateral margins not serrate ; eighth tergite densely granulose, coarsely, sparsely 

 punctate, broadly rounded at opex. Presternum coarsely, densely punctate, 

 transversely rugose, sparsely pubescent ; anterior margin truncate, with an in- 

 distinct, short, broad, median lobe. Anterior femur with a large, acute tooth, 

 which is not dentate on outer margin. Anterior tibia arcuate, with a slight 

 dilation at apex; middle tibia slightly arcuate, and slightly expanded at apex; 

 posterior tibia straight. 



Length 8 mm., width 3.5 mm. 



Redescribed from a male in the United States National Museum, 

 collected at Ft. Valley, Ga., April 4, 1921, by E. R. Selkregg. 



Female. — Differing from the male in having the front of the head uniformly 

 greenish black, with the punctures purplish, the last visible sternite usually 

 sinuately truncate at apex, with the angles strongly produced, and the anterior 

 tibia unarmed at apex. 



Type locality. — Of chrysoela, Georgia; of hyhernata, Carolina; of 

 mellicula, North America; present location of the types of these 

 three species unknown to the writer. Of viridipunctato :, North 

 America; type supposed to be in the collection of Rene Oberthiir, 

 but has not been examined by the writer. 



Distribution. — This species is distributed throughout the Southern 

 States and specimens have been examined from the District of 

 Columbia and various localities in the following States: Alabama, 

 Florida, Georgia, Louisiana, Mississippi, North Carolina, South 

 Carolina, Texas, and Virginia. It has been recorded by Provancher 

 (1877) from St. Hyacinthe, Quebec, Canada, but this record may be 

 from an erroneously identified specimen. 



Hosts. — This species has been found breeding in buttonwood (>Cono- 

 carpus erect a Linnaeus) at Key West, Fla., by E. A. Schwarz, and
