SMODICUM. 



Antennre 11 -articulate, breviusculae, glabrae. 

 Thorax capite vix latior, longiusculus, depressus. 

 Palpi breves aequales. 

 Elytra apice rotundata. 



The body is linear and very much depressed ; the anterior ace tabula have a 

 tendency to form a right angle externally. This genus connects the present group 

 with Callidium.

 large reniform slightly impressed spot on each side of the prosternum, which is 

 truncate posteriorly and marked with a short furrow. 



GRACILIA. 



Antennae longiusculae, tenues, pubescentes. 



Thorax capite vix latior, elongatus depressiusculus, lateribus paulo rotundatis. 



Palpi labiales brevissimi. 



Elytra apice rotundata. 



The body is elongate and depressed, the femoral club very large. 



1. G. FUSCA. — Opaca, fusca, cinereo-pubescens ; thorace latitudine sesqui longiore, dense punctate, linea 



dorsali Isevi ; elytris parce obsoletius punctatis, abdomine non brevioribus. Long. •27.

 JVothrus fuscus, Hald. 



From New York and Georgia, rare. On a superficial examination I see no 

 difference between this and the European G. pygmcea. 



2. G. MANCA. — Opaca, fusca, cinereo-pubescens ; thorace latitudine sesqui longiore, lateribus rotundatis 



punctato linea dorsali vix laevi, elytris minus parce punctatis abdomine brevioribus. Long. -32. 



New York, rare ; easily distinguished from the preceding by the shorter thorax 

 and the abbreviated elytra.

Antenna breviusculae, tenues, pubescentes. 



Oculi profunde emarginati fere divisi. 



Thorax capite latior, quadratus, transversus lateribus non rotundatus. 



Elytra thorace latiora apice truncata.
