NOTES ON THE PADERINI. 
By Tuos. L. Casey. 
As preliminary to a revision of our Pederii,* it is desired at the 
present time to publish a few notes and descriptions in the form of a 
prodromus, 
HOMCEOTARSUS Hochh, 
At the time of publication of the description of Hesperodium (Bull. 
Cal. Acad. Sci., II, p. 33), the genus Homaofarsus was unknown to me 
in nature, but within the past year I have received from Herr Reitter of 
Vienna a perfect male specimen of HZ. Chaudoir7, the type of the genus, 
and find that our species should be generically associated with it, at 
least for the present. It is true that there are certain differences of 
minor value, as for instance in the antenne, which in the Armenian 
species have the joints strangulated at base, and the eleventh joint fusi- 
form and gradually pointed at apex. The sexual characters are also 
different, presenting a form of emargination of the fifth and sixth seg- 
ments, which is quite foreign to our species. These differences are, 
however, of a secondary or perhaps subgeneric value, and when the 
genus is thoroughly investigated the species assigned more particularly 
to Hesperobium, will form one only of a number of subgenera; until 
that time the name can very well be suppressed. 
In the remarkable collection recently made by Mr. H. H. Smith in 
Brazil, there are several very peculiar species; one, for example, in 
which the large lobe of the third segment in the male is deeply bilobed, 
giving the appearance of two well developed lobes, and another large 
slender species, having unusually long and slender legs, in which the 
posterior trochanters of the male are prolonged in a slender spine which 
extends to the apex of the femur, reminding us somewhat of the same 
part in the Carabide genus Platidius of Chaudoir. 
The following table indicates the differential characters of the 
eastern species allied to paliipes Grav. 
Elytra subequal in length to the prothorax.

* In order that this work may be as complete and useful as possible, it is earnestly 
hoped that those who have material to spare, may consent to its utilization in the pro- 
posed revision, In connection with this request it should be suggested, and I think 
most collectors will readily agree, that it would be far better for the ultimate welfare 
of Science if unique types could be retained in the cabinet of the reviser. The con- 
tributors would, however, in every case receive in return a larger set of carefully de- 
termined species than can probably be included in their individual series.
