REVISION OF THE GENUS PLEUROPOMPHA 
LECONTE (COLEOP., MELOIDiE ) 1 
By F. G. Werner

Genus Pleuropompha LeConte 
LeConte, J. L., 1862, Smiths. Misc. Coll. 3:273. Wellman, C., 
1910, Ent. News 2 1 : 2, 2 15, 221, 2 1910, Can. Ent. 42 :394. Van 
Dyke, E. C., 1928, Univ. Calif. Publ. Ent. 4:400, 404. Geno- 
type: Lytta costata Lee., 1854, monobasic. 
The genus Pleuropompha belongs to the tribe Lyttini auct. 
and should be placed near Epicauta Dej. because of the patch 
of silky pubescence on the inner face of the anterior femora. 
From Epicauta it differs in having costae on the elytra. The 
other costate genus of the tribe, Pleuropasta Wellm., does not 
have the femoral patch and is glabrous. Elongate third to fifth 
antennal joints of the male distinguish it from all of the genera 
of the tribe. 
Head subquadrate, densely pubescent except for an impressed 
median line. Thorax campanuliform, also with an impressed 
median line. Antennal joints three to five in the male more or 
less elongate, smooth. All tibiae with two spurs, in both sexes. 
First joint of anterior tarsi of male slightly elongated but tarsi 
not otherwise modified. 
Two very distinct species are included, both from North 
America. These may be found to inhabit also the northern 
states of Mexico. 
Key to Species of Pleuropompha 
A. Each elytron with four strong costae, raised suture and mar- 
gin set off by denuded margins. Pubescence white 
costata (Lee.)
