ITHYCERUS,SchoeRb. 



I. eurmUonoides, Herbst. 



I have always considered the Cnrculio punctatulus, 

 Fabr. and Oliv. synonymous with this, but Germaris of 

 the opinion that it is a different insect. 



Cnrculio novaeboracensis, Forster. 



^ Genus THECESTERNUS, Nob. 

 Anterior part of the pectus excavated for the reception 

 of the rostrum. 



Natural Character. 

 Body convex, firm, unequal : rostrum very short, thick 

 entire : antennae rather slender, inserted near the middle 

 of the rostrum, in a deep, somewhat angulated groove; 

 first joint oblong turbinate, a little arquated; second and 

 third short, subturbinate, the latter shorter; fourth and 

 eighth very short, quadrate or transverse; club rather large 

 of vt^hich the basal joint f^or two joints?] is as long again 

 as the ultimate one, which is subacute: €?/e? a little ob- 

 lique, somew^hat acute before, oblong subovate : thorax 

 longitudinally son>ewhat quadrate : smtelnone: elytra con- 

 nate, rigid, hardly broader at base than the thorax, narrow- 

 ed at tip and concealing the podex : pectus anteriorly deep- 

 ly excavated to receive therjstrum r/es/, anterior piirs ap- 

 proximate: posterior pair distant : thighs not diiated : tibiae 

 with a short, thick, or double spine at tip : iarsi simple. 



Observations. 



I proposed this genus when describing the species, but 

 omitted the name. It differs from Brachycerus, F. & Epi« 

 sus, Billb. by the pectoral excavation; general form of the 

 body; less robust antennae, & larger club.
