The Irish Naturalist, 
August, 
The dorsal plates i-8, inclusive, are rounded at the 
posterior corners, but the posterior border of the 9th is 
more or less excavated towards the lateral extremities, 
tending to give the corners the effect of angular projections. 
These projections are much more developed in the case 
of the iith dorsal plate, and are even more marked still 
in the case of the 13th ; the other posterior dorsal plates 
are all more or less rectangular or rounded posteriorly. 
In some cases the 7th dorsal plate may exhibit a tendency 
towards the same lateral excavation of the posterior border 
as that here noted in the case of the 9th, iith, and 13th. 
All the dorsal plates are more or less completely marginated. 
Antennal segments varied in number from 28 to 34 ; 
the distal segment is generally about i| times the length 
of the penultimate one, but in one case it was noted that 
the last segment was of greater length than the two previous 
ones taken together in the following proportion : — 
The 32nd segment : 30th-t-3ist :: 19 : 15 
The antennae are markedly more hairy distally than 
proximally. The colour of the segments varies from yellow 
to dark brown, the last joint being the lightest.
