stood than by representing them in tabular form; indeed I do not feel at all certain 
whether the modifications of the tarsus or of the breast should be treated as of superior 
value for taxonomical purposes. I incline to the opinion that the distinctions of the 
tarsus may prove to be of predominant importance, but they are very difficult to follow 
in a satisfactory manner without the aid of microscopical preparations, and the material 
we have received is insufficient for this purpose. Hence I feel very doubtful as to the 
correct generic position of some of the species I have described, especially those I have 
placed in Eustilbus. 
‘The species of Phalacride are usually found upon flowers or low plants. 
PHALACRUS. 
Phalacrus, Paykull, Fauna Suecica, iii. p. 438 (1798) (pars); Erichson, Nat. Ins. Deutsch. iii. 
p. 109. 
This is one of the most widely distributed genera of the family, and consists at 
present of about thirty species from various parts of the world. The representatives 
found in our region are in all probability really congeneric with those of Europe and 
North America.

Extremely similar to the European P. corruscus, but with very differently formed 
antenne. I possess some specimens named by Morrison and confirmed by Dr. Horn, 
but nevertheless am not sure that they are really Leconte’s species. From the localities 
other than Sonora we have a very poor supply of examples, only indeed either one or 
two specimens from each; these latter do not exactly agree with one another, and it 
may be that not all, or indeed any, of them are actually conspecific with the examples 
from Sonora. 
2. Phalacrus rufipes, sp. x. 
Breviter ovalis, convexus, niger, minus nitidus, pedibus rufis, antennis flavis, 
Long. 27 millim. 
Hab. Mexico, Cordova (Sallé). 
Of short form, scarcely narrower behind. Antenne yellow, the terminal joint of the 
club elongate. Head feebly punctate. Thorax large, not margined at the base in the 
middle. Elytra dull, with well-marked sutural stria, and extremely minute serial 
punctures. Sides of the thorax and the apex of the elytra picescent. Legs, including 
the front coxze, red; under surface piceous. ‘Two specimens.
