 GNAPHALODES, Thorns. 

 A species belonging to this genus has occured in Texas. It should 

 be placed before Chwn with the following definition: 



Prothorax ivilh lateral spine behind /he middle; antenmr densely fring- 

 ed beneath, inner angle of joints 4-j spinose; elytra Inspinose at tip, episterna 

 of metathorax ivide, scent pores distinct. 



The scutellum is triangular, larger than in Chion, and the eyes are 

 less coarsely granulated; the prosternum is perpendicular behind, and the 

 mesosternum convex. The body is brown, uniformly clothed with gray 

 brown pubescence, paler and more dense on the scutellum. The species 

 may be considered an occasional visitor rather than a permanent addi- 

 tion to our fauna.

EBURIA, Sen: 



Contains several species of moderate size readily distinguished b\ 

 the two pairs of ivory spots on the elytra. We reproduce the Synopsis 

 offered by Dr. Leconte in 1873, ^^^ published in S. M.C., No. 264.

 at tip; 

 a. — Front co.\?e not angulated. fissure completely closed; prothorax abruptly con- 

 stricted before and behind, tuberculate and strongly armed on the sides: color 

 piceous; 



Body glabrous above, slightly pubescent beneath, prothorax feebly grossly 

 punctured, elytra with very small ivory spots of which the medial pair and 



the outer basal one are frequently wanting Ulkei.
