cabinets of Mr. Dale and Mr. Waterhouse ; the fifth in that of the 
Rev. Wm. Little, captured at Raehills in Dumfries-shire ; the 
sixth received by Mr. 8. Stevens from Newcastle, and the seventh 
kindly presented to me by Mr. Heysham of Carlisle ; it appears 
to be rare and only found in the north.

This insect differs from the preceding in having the thorax sub- 
quadrate, the sides slightly rounded, sometimes nearly straight, 
and armed on each side adjacent to the anterior margin with a 
large tooth, behind which are several smaller ones ; the elytra less 
deeply punctate-striate, the interstices flat, broader than the striz, 
and very finely strigated transversely or coriaceous. I forwarded 
many specimens of this insect to Schénherr and Germar, with 
the name Cure. atramentarius of Marsham and Kirby, citing 
Curc. stygius as synonymous, with a note of mterrogation to the 
latter name ; all my specimens were referred by them to Magd. 
stygia of Gyll., aterrima of Fab. ; subsequently I have had an op- 
portunity of examining a typical example of Cure. stygius of Mar- 
sham, and I have now no doubt whatever it 1s but a small nar- 
row variety of his Cure. atramentarius. According to the mu- 
seums of Fabricius and Banks, the first examined by Germar and 
the last by myself, this species 1s doubtless the true Curc. ater- 
rimus of Fabricius ; but he refers it to Linnzeus ; yet the Linnean 
Cure. aterrimus, according to the insect in his cabinet, is the 
Apion marchicum of Herbst, and as it does not entirely agree 
with the description of Linnzeus, the name is sunk ito a syno- 
nym (see notes on Apion marchicum) ; under these circumstances 
I consider there will be less risk of confusion by followmg Ger- 
mar and Stephens in adopting the oldest name. 
This is rather a common insect im the south of England, but 
apparently very scarce in the north ; I have found it in Yorkshire, 
and plentifully near Gravesend, always upon the common elm- 
tree (Ulmus campestris), in July.
