to parallel at the sides, and the punctuation of its upper surface not quite so close. 
The anterior tibiae of wmbrosus, moreover, are scarcely perceptibly crenulated on 
the outer margin until the apical third, where there are about four very small | 
teeth, which are often almost obliterated, and of which the first and last are usually 
the most prominent ; whereac in mawrus the outer margin is gradually more strongly 
and sharply denticulated towards the apex, where the usual projecting and larger 
teeth are more distinct than in wmbrosus. 
Compared with wmbrosus, the British insect hitherto considered by us as — 
mawrus (and which agrees well with description of ovatus, and with my types of the 
latter corroborated by M. Brisout) is, on the average, half a line smaller; much 
more shining, having its punctuation not nearly so close, and with its thorax cer- 
tainly not longer or narrower in proportion, and its anterior tibizs: even more di- 
lated towards the apex, and with their outer margin very coarsely and irregularly 
“jagged.” This species varies considerably, both in size ard the armature of its 
anterior tibiz, and sometimes a little in the punctuation of its elytra; apse not 
qnite to such an extent as its immediate ally flavipes. 
According to M. Brisout (and this is corroborated by the only continental type 
of maurus I have seen), M. mawrus is rather larger than wmbrosus. 
M. incanus, Sturm. I have observed, among some unexamined specimens of © 
British Meligethes belonging to Mr. G. R. Waterhouse, an individual labelled 
incanus, Stm., Hr. (Ins. Deutschl., iii, p. 190), and, in my opinion, correctly 
referred to that species, which is new to our list. It certainly cannot be confused 
with any of our recorded Meligethes. This specimen was taken by Mr. Waterhouse 
at Darenth Wood, on Echium vulgare, in June, 1859. It is of the size of ordinary 
ovatus (maurus, Wat. Cat., nec Stm.), being apparently a small example of its 
species, which is given by Hrichson as only 4 lin. less shan wmbrosus ; and is of an 
exactly oval outline, convex, dull (being as closely and finely punctured as wmbrosus), 
clothed with very evident, depressed, grey hairs, with the two basal joints of the 
antenna pitchy-testaceous, and the anterior tibize considerably dilated towards the | 
apex, with their outer margin finely denticulated to a little below the middle, and 
then armed with three or four stronger and rather irregular teeth. 
According to M. Brisout, M. incanus has been found by him on Solanum 
dulcamara and Nepeta cataria. His characters for the species appear to agree 
well with the insect above recorded. 
M. seniculus, Er., according to M. Brisout, is only a slight variety of murinus, 
Er., which name he retains. He does not, however, refer to Erichson’s character 
for the latter, of the possession of stout seta on the entire outer edge of the pos- 
terior tibize. 
M. ovatus, on Labiacee. Not uncommon at Mickleham and Esher. <A constant 
character for this species seems to be afforded, according to M. Brisout, by the 
slight sinuation of the posterior margin of each elytron, the sutural angle of which 
forms a slight rounded projection (t.e., the apex is not truncate). 
M. flavipes, on Ballota nigra, Melilotus, and Cirsium lanceolatum. 
M. rotundicollis, on Trifolium mediwm and Genista. Since my original record 
of this species, I have observed it in the collections of Mr. Waterhouse, Dr. Power, 
and Mr, Champion. 
M. lugubris, on Mentha.
