COLEOPTERA. 113 
. Rurnotracus, Dalm.*, 
Differs from the preceding one in the head, which is narrowed and 
prolonged anteriorly in the manner of a snout; in the palpi, of which 
the last joint is rather thicker than the preceding cones, and truncated 
at the end; in the antennez, shorter than the body, slightly dilated, 
and somewhat serrated at the extremity; and in the almost orbicular 
thorax. 
These Insects are evidently allied to those of the following genus; 
the 
Necypatis, Lin., 
The only one of this tribe in which the elytra are either very short, 
and squamiform, or prolonged, as usual, to the extremity of the ab- 
domen, but abruptly contracted a little beyond their origin, then 
much narrowed, and terminating in a point, or subulate. This is the 
only point in which these last mentioned Insects resemble the (Ede- 
mere, with which Fabricius has arranged them. The last joint of 
the palpi is a little longer, and almost obconical and compressed. 
Their abdomen is long, narrow, contracted, and as if pediculated at 
base. The wings are folded at their extremity. 
Those species in which the elytra are subulate will form a first 
subgenus, 
Srenoprervs, J/liq., 
From which we might separate various species, foreign to Europe, 
with shorter antenne, thickest, and almost serrated at the extremity f. 
In those that inhabit France, such as the 
N. rufa, L.; or the Lepiure & étuis étranglés, Geoff.; Ib., 74> 
i, 6, the antenne are filifurm and as long as the body f. 
Those in which the elytra are short and squamiform will constitute 
the subgenus 
NEcyYDALIS, proper, 
Which corresponds to the genus Molorchus of Fabricius. Its type 
is the Necydalis major of Linneus and Geoffroy—Oliy. Ib. I, 1. 
Found in old Willows in June and July§. 
Certain Insects generally proper to the African islands, New Hol- 
land, New Ireland and New Zealand, ambiguous in several respects, 
and which, in a natural order, should perhaps be placed between the

luridus, punctatus, albicans, of the Entom. Bras,, of Kliig.

{ The Necydales atra and preusta, Fab., and the N. femorata of Germar, are 
analogous. 
§ See Fabricius, Olivier, Kliig, Kirby, and Schcenherr. 
The Stenocorus hemipterus of Fabricius, which should apparently be placed here in 
a natural order, approximates more closely to the Stenocori of Germar and Dejean,
