COLEOPTERA OF THE LOWER RIO GRANDE. IZI 



broader than long; margin broad, more so at base, rather 

 widely reflexed, sides broadly regularly arcuate to near the 

 hind angles where they are slightly sinuate. Hind angles 

 obtuse, hardly rounded, a deep but vague foveiform depres- 

 sion within, which is limited anteriorly by a rather indistinct 

 carina. This carina is continued in the form of an elevated 

 line, parallel with the side margin, nearly to the apex. Disk 

 strongly transversely rugose. Elytra broad, sides nearly 

 parallel, slightly broader behind the middle, apex truncate 

 and slightly sinuate, sutural angle nearly right, not rounded. 

 Disk flattened, striate, stria? impressed, very finely sparsely 

 punctulate at bottom, interspaces broad, flat, or even slightly 

 concave in places, sparsely irregularly beset with punctures 

 which are larger than those of the striae. Beneath shining, 

 thorax indistinctly punctured, the abdomen finely rugose, the 

 rugosities transverse in the median region, at sides radiating 

 from vague impressions. Length 11.5 mm. Brownsville, 

 beaten from plants in July. Mr. Schwarz has compared my 

 specimen with Mexican examples and pronounces them identi- 

 cal. 



C. planulata Lee. Not uncommon, though by no means 

 abundant, on herbage in the tropical jungles. At the time of 

 Dr. Horn's revision of the genus, only one specimen, of 

 doubtful locality, was known. The above record will therefore 

 serve to fix the claim as native to the United States. Some 

 specimens are almost testaceous in color, bronzed or greenish 

 in the vicinity of the elytral humen. June and July; Town- 

 send and myself. 



C. viridipennis Say. Brownsville; Mr. Townsend, Found 

 in the Gulf States from Florida to Texas. 



C. decora Fabr. Abundant at Browsnville, during the 

 whole length of my stav. chief!)' in the more humid spots, on 

 herbage; not confined to the wooded regions, but common 

 also in fields. Included in Townsend's series. Extends 

 through the Gulf States and into Mexico. 



Philophuga viridicollis Lee. Two or three specimens
