Those, in which it is atjleast as long as the mesothorax, ba where 
the elytra, hardly longer than the abdomen, or shorter, are dilated 
at their base, and afterwards narrowed, form another subgenus, the 
Issus, Fab.(2) 
Sometimes the antennz are at least as long as the head, and most 
frequently inserted into an inferior emargination of the eYes. 
* . Anotia, Kirb., 
Which in a natural order comes near his Otiocerus, and approx- 
imates to Issus in the insertion of the antennz(3). 
Astraca, Lat.—Delphaz, Fab. 
Where the antennz are inserted into an inferior emargination of 
the eyes, are as long as the head and thorax united, and have their 
first joint usually longer than the second, compressed and angular. 
There are no simple eyes(4). 
De.pnax, Fab. » 
Where the antennz are inserted in a similar manner, but are never 
much longer than the head; the first joint is much shorter than the 
following one and without ridges. The simple eyes are apparent(5). 
DerseE, Fab. 
These Insects are unknown to me; I presume, however, that they 
approach those of the preceding subgenera, that of Anotia in Sena 
cular.
