distinct, not extended on the margins ; basal lines distinct, ob- 

 lique; region of the posterior angles a little, but widely, depressed, 

 rufous or sanguineous, and by transmitted light it appears reti- 

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

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

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

 punctured; interstitial spaces depressed, third with a single 

 slight puncture on the posterior fifth from the base ; beneath 

 black; posterior angles of the pectus, epipleura and feet piceous; 

 anterior tarsi with four not widely dilated subquadrate joints, the 

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

 dense fastigiate hairs ; intermediate tarsi also somewhat dilated. 



Length less than two-fifths of an inch. 



The elytra are hardly perceptibly sinuous near the tip. 



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

 New Orleans, is a doubtful congener of the 0. helopoides Fabr., 

 than which the body is somewhat more elongated, the thorax 

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

 appearance of the Harpalus terininatus ox Calathusgregarius 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 striae of the elytra to their termination is a remarka- 

 ble character, even more obvious than in the helopoides.

DIC^LUS Bonelli. 



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

 the name of chalybaeus Sp. Gen. 2. 



2. D. ELONGATUS Bonelli Say, Trans. Amer. Philos. Soc— 

 Dejean is of the opinion that this is not the elongatus of Bonelli, 

 and has described it with the name of furvus, but he has not 

 stated the reasons for this opinion. 



\_D. farvus Dej. is totally distinct from D. elongatus: it is 

 allied to, and perhaps identical with D. ovali's Lee. — Leg.]
