A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 203 



DISTRIBUTION 



From material examined : 



Texas: San Diego, April 3 to May 2 (E. A. Schwarz). Brownsville, June 8, 

 1934 (J. N. Knull). Cotulla, May 11, 1900 (F. C. Pratt). Corpus Christi, 

 June 6, 1906 (C. R. Jones). 



Host. — Knull (1937) records that adults were reared from dead 

 branches of "Acacia felicloides Car." collected at Brownsville, Tex. 

 The larvae work beneath the bark and enter the sapwood for 

 pupation. 



Very little variation was observed in the specimens examined 

 except in size. The length is from 15 to 20 mm. 



Specimen No. 1 (lectotype No. 3762) and specimen No. 2 (female 

 paratype), which are without locality labels in the LeConte collec- 

 tion, are without any doubt the specimens mentioned in the Original 

 description as having been collected by Dr. Berlandiere. LeConte 

 described both sexes and gave the distribution as Tamaulipas, extend- 

 ing to Matamoros and probably into Texas, and the lectotype is 

 labeled U C. acuminata Lee, Berlandiere." 



This species has been placed as a synonym of acutipennis Chevrolat, 

 but it differs from acutipennis in being usually larger, and in having 

 the foveae on the elytra smaller and more uniform in color with the 

 rest of the surface, the elytra narrowly rounded at the apices, the 

 tooth on the femur acutely triangular, and the apical segments of 

 the antenna in the male testaceous and the front of the head without 

 a projecting plate above the clypeus.

Male. — Moderately elongate, rather strongly depressed above, strongly shining, 

 piceous, with a distinct greenish tinge in different lights, cupreous in the foveae on 

 elytra ; beneath brownish cupreous, violaceous blue along margins of sternites and 

 on tarsi, more strongly shining than above. 



Head uniformly brownish cupreous, with a narrow, longitudinal carina on 

 occiput, and a small, distinctly elevated, transverse, projecting plate behind 

 clypeus; front slightly uneven and convex, transversely depressed behind clypeus; 

 surface coarsely, confluently fossulate-punctate, longitudinally rugose, rather 

 densely clothed with long, erect, whitish hairs; clypeus broadly, shallowly, 

 arcuately emarginate in front, arcuately rounded on each side. Antenna uniformly 

 brownish cupreous, with a distinct golden tinge, slightly narrowed to apex ; inter- 

 mediate segments compact, quadrate, slightly wider than long, broadly sub- 

 truncate at outer margins; third segment slightly longer than following three 

 segments united. 



Pronotum nearly twice as wide as long, narrower at apex than at base, widest 

 near apex ; sides arcuately converging at apical angles, obliquely converging and 

 more or less sinuate from near apical angles to posterior angles, which are
