in division C.,) although equally common, and less intimately related to the 
other groups, have not, however, been commemorated by a generic name. 
Tegrodera Lec. was established on a single Californian species, differing 
remarkably in appearance from all the other species known to me, and having 
the claws of the tarsi apparently toothed instead of bifid. On close examination 
I find that this apparent tooth is not a protuberance on the claw, as in Cysteo- 
demus, but merely the ordinary inferior division of the claw, which is here 
shorter and more intimately connected with the claw itself, the line of junction 
being visible quite to the base of the claw. 
In. consequence of the changes in classification, which are here proposed, I 
give the following as the diagnosis of Lytta:

Cantharis vulnerata Le Conte, Ann. Lyc. 5, 159. 
San Diego, September, abundant on a species of Baccharis. Black shining, 
above glabrous. Head sparsely punctured in front, scarcely so behind, slightly 
dilated behind the eyes, which are oblique; base subemarginate, posterior angles 
rounded, with a large rufous spot reaching almost to the eyes, and ¢xtending 
obliquely forwards meeting the opposite spot, so as to enclose a large occipital 
black spot, which is slightly channeled; clypeus and labrum punctured and pu- 
bescent with erect black hairs. Antenne about as long as the head and thorax, 
moderately thickened, with the external joints subglobular. Thorax scarcely 
wider than the head, pentagonal, sparsely punctured, disc flattened, lateral angles 
acute, marked with a large rufous spot. Elytra finely scabrous. Legs black, 
intermediate tibiz curved; posterior tibia armed with two broad spurs, which 
are concave and obtuse at their apex.
