which are found almost exclusively in Northern and Central Asia and 
in Europe; one or two, however, have occurred in Algeria; of the 
sixteen European species one only is indigenous to Britain, although a 
second, A. micans, has been very doubtfully introduced ; A. lineatocollis, 
as above pointed out, has the power of emitting a powerful and disagree- 
able odour, and also of making a strong stridulating noise by moving 
the thorax up and down, so that it rubs upon the neck of the elytra ;* 
the larva of A. lineatocollis is found in the stems of thistles (Cirswm) ; 
it scarcely differs from that of A. asphodeli, which is figured in profile 
by Perris (Larves des Coléoptéres, pl. xiii. figs. 5, 18); it is not much 
narrowed behind, and has the dorsal tubercles rather strongly developed ; 
the legs are wanting, and there is scarcely a trace of ocelli, 
A. lineatocollis, Don (wngusticollis, F.; Saperda cardui, Steph.). 
Elongate, black or pitchy black, pilose, clothed with yellowish pubes- 
cence, which is very thick on the under-side; head long, pubescent in 
front and at sides, and with a thick line on vertex, strongly punctured, 
antenne ringed with white ; thorax about as long as broad, very slightly 
narrowed in front, strongly and rather closely punctured, with three 
strongly-marked longitudinal lines of pubescence, of which the central 
one continues the line on vertex; scutellum densely clothed with 
pubescence ; elytra coarsely punctured at base, more finely at apex, 
irrorated with more or less close pubescence, and presenting a finely 
mottled appearance ; legs rather stout, clothed with greyish pubescence. 
L. 12-18 mm. 
Male smaller and more slender, with the antenne longer than the 
body and the fifth ventral segment broadly emarginate at apex. 
Female larger and broader, with the antenne as long as the body. 
On thistles and Heracleum spondylium ; very local and, as a rule, rare; Darenth 
Wood and West Wickham Wood; Monks Wood; Norfolk ; Weston-on-the-Green, 
Oxfordshire ; Wicken and Burwell Fens; Whittlesea Mere; I have taken it in 
abundance in Langworth Wood, near Lincoln, on a patch of Heracleum spondylium, 
not yet in flower; on June 11th, 1885, I took fifty specimens, and a few days 
previously as many as these had been taken in the same ride in the wood. The Rev. 
J. A. Mackonochie has found it in the same locality this year (1889), but much more 
sparingly. 
SAPERDA, Fabricius. 
This genus is closely allied to the preceding, from which it differs in 
having the antenne 11-jointed; it contains about fifty species, which 
are widely distributed throughout the world, and inhabit Europe, North, 
Central and South America, South Africa, &c. ; one or two also have 
been described from the Australian region ; they differ very much in 
size and general appearance, and have been divided into several sub- 
genera by Mulsant ; of the eight European species three are found in 
* I am not sure whether this sound is not, in part at least, produced by the 
friction of the back of the head against the under side of the front of the thorax.
