A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 11 



Colombia: Carthagena (type lebasi). 



Guatemala: Chacoj, Panzos, and Yzabel (Waterhouse 1882, 1889). 



Nicaragua: Chontales (Waterhouse 1882). 



Mexico: Matamoros (Chamberlin 1926). Zimapan, Oaxaca ; Orizaba, Jalapa, 



and Misantla in Vera Cruz, and Cuernavaca in Morelos (Waterhouse 



1882, 1889). 



Schwarz (1878) and LeConte (1878) record this species from 

 Florida, but all Florida records should be referred to acornis Say. 



Hosts. — Burke (1918) records the larvae mining the sapwood and 

 heartwood of dying and dead palo-verde (Gercidium torreyanum 

 (Watson) Sargent) and probably "bacchata" (Zizyphus obtusif olia) . 

 Chamberlin (1926) records it from peach, white oak, and hickory, but 

 these records should be referred to Chrysobothris calcarata Melsheimer 

 (not Chevrolat), which is a synonym of Chrysobothris floricola Gory. 

 Adults have been cut from huisache (Acacia famesiana (Linnaeus) 

 Willdenow) and collected on horsebean [Parhinsonia sp.). 



This species is rather uniform in coloration, but the cupreous 

 fasciae on the elytra are more distinct on some specimens than on 

 others. In some specimens examined the sides of the pronotum are 

 less divergent posteriorly, the median smooth space on the pronotum 

 obsolete, and the transverse depression variable in depth. The under- 

 side of the abdomen is foveolate -punctate in a few of the specimens 

 studied. The clypeus is usually sinuate, with a small median tooth, 

 but in a male from Arizona the anterior margin of the clypeus is 

 slightly, arcuately emarginate, without any indications of a median 

 tooth. The length is from 12 to 17 mm.

Male. — Rather broadly elongate, slightly convex above, subopaque, bronzy 

 green, with a distinct purplish tinge ; beneath olivaceous green, with distinct 

 purplish reflections in different lights, and more strongly shining than above. 



Head bronzy green, distinctly cupreous in different lights, with an inconspicu- 

 ous longitudinal carina on occiput, and a short, oblique, elevated carina on each 

 side above the antenna ; front flat ; surface glabrous, finely, sparsely punctate 

 on occiput, densely fossulate-punctate on vertex, and coarsely foveolate-punctate 

 or rugose on front ; clypeus sinuate in front. Antenna short, bronzy green, with 

 a faint cupreous tinge, gradually narrowed to apex ; intermediate segments 

 compact, subtriangular, as long as wide, broadly rounded at outer margins ; third 

 segment one-third longer than the fourth. Eyes separated from each other on 

 the occiput by about their width at widest part. 



Pronotum twice as wide as long, distinctly wider at base than at apex, 

 widest near base; sides slightly, arcuately converging from base to apex; 

 posterior angles rectangular ; base transversely sinuate on each side, the 

 median lobe slightly produced and broadly rounded; disk regularly convex, 

 with an obscure, oblique carina at the posterior angles ; surface densely, finely 

 granulose, finely, densely, transversely rugose, finely punctate between the 

 rugae. 



Elytra slightly wider than pronotum, twice as long as wide; sides nearly 

 parallel from humeral angles to apical third, then obliquely converging to the 

 tips, which are conjointly broadly rounded ; disk regularly convex, with vague, 

 longitudinal costae, but without basal or humeral depressions ; surface glabrous, 

 densely, finely, uniformly scabrous, slightly rugose basally.
