distinct, not extended on the margins; basal lines distinct. <il> 

 lique; region of the posterior angles a little, but widely, dejiri'.ssed, 

 rufous or sanguineous, and by trausfuitted light it apjiears reti- 

 culated; impunctured ; posterior angles rounded, but not ob- 

 tusely so ; greatest width a little behind the midle ; elytra with 

 the striae continued parallel to the tip, well impressed, minutely 

 puuetured; iiiter.stitlai .spaces depressed, tliird with a >ingle 

 slight puncture on the posterior fifth from the base ; beneath 

 black; posterior angles of the pectus, epij)leura and feet piccous; 

 anterior tarsi with four not widely dilated sub(|uadrate joinL-^, the 

 fourth joint being as large as the tbird, and all beneath with 

 dense fastigiat»i hairs; intermediate tarsi also somewhat diluted. 



Ixjngth less than two-liftbs ol" an inch. 



The elytra are hardly perceptibly sinuous near the tip. 



The specimen, for which I am indebted to Mr. J. IJarabino of 

 New Orleans, is a doubtful congener of the 0. hrli>pnitl,,s Tabr-, 

 than which the body is somewhat more elongated, the thorax 

 more gradually narrowed before. It has at first sight more the 

 appearance of the Jlurpalus Unninatus or Ca/af/ius</rct/tin'us Say, 

 The intermediate tarsi are somewhat dilated, the anterior tarsi 

 are not widely dilated and the terminal joint is as large as the 

 preceding one. I place it in this genus provisionally, more speci- 

 mens may show this arrangement to be incorrect The parallel- 

 ism of the stria3 of the elytra to their termination is a remarka- 

 ble character, even more obvious than in the helopoides.

1. 1>. PURPURATUS Bonelli. — Since described by Dejean under 

 the name of chali/hasm Sp. Gen. 2. 



2. D. ELONQATUS Bouelli Say, Trans. Amer. Philos. Soc. — 

 Dejean is of the opinion that this is not the rhnj/itus of Bonelli, 

 and has described it with the name of yH;v7A«;, but be has not 

 stated the reasons for this opinion.
