154 RHYNCHOPHORA. [Apton. 
Male usually smaller than female, with the anterior tibie curved at 
apex and armed witha small tooth, and with the first joint of the pos- 
terior tarsi furnished with a small hook on its internal apical border. 
On thistles; generally distributed and common throughout the kingdom; the 
larva has been observed in the central stalk of the leaf of the artichoke (Cynara 
aflame), in the stems of Cirsiwm arvense, and in the axils of the stems of species of 
ardwus. 
Group 11. 
Strie of elytra very fine, more-or less obsolete, thorax almost smooth 
(on Gnaphalium (Filago) gallicum, the narrow cudweed, very rare). 
A. levigatum, Kirby, nec Payk. (brunnetpes, Boh.). Black, rather 
shining, glabrous, with the elytra black, bluish, or slightly violet; head 
quadrate, forehead with a semicircular finely striated depression ; rostrum 
as long as head and thorax, curved and cylindrical, finely and diffusely 
punctured ; thorax cylindrical, about as long as broad, very finely punc- 
tured, almost smooth, and with the fovea before scutellum scarcely 
apparent ; scutellum very small; elytra convex, broadest a little behind 
middle with very fine and more or less obsolete strize and broad and flat 
interstices, which are shining; legs black or obscure pitchy-brown. 
L. 2-23 mm. 
Male with the rostrum shorter than in the female; according to 
Walton the male is entirely black, whereas the female has the elytra of 
a rich violet colour. 
By sweeping low plants, August and September, extremely rare; it occurs on 
Gnaphalium (Filago) gallicum, on which plant the larva lives in a gall on the 
terminal bud; taken many years ago in a corner of a field at Birch Wood, Kent, by 
Mr. Walton, Mr. Waterhouse, and Mr. S. Stevens; the latter gentleman informs me 
that the locality is destroyed ; it bas also been taken at Birch Wood by Mr. F. Smith 
and in the same locality on Gnaphalium gallicum by Dr. Power. 
Group 12. 
Small or very small species, with the sutural strie prolonged to the 
base of elytra (chiefly on species of Thymus and Mentha). 
A, flavimanum, Gy]ll. (picicorne, Steph.). A small and rather 
elongate species, black, pubescent ; head broad and short, with close 
rugose punctuation ; rostrum dull, pubescent almost to apex, as long as 
head and thorax; antenne slender, with the base pitchy-testaceous ; 
thorax almost as broad as long, strongly constricted in front, rounded at 
the sides, with the anterior margin raised, finely and closely punctured ; 
scutellum small; elytra a little broader at base than thorax, with the 
sides subparallel, strie rather strong and strongly punctured, interstices 
narrow; legs black, rather stout, tibie more or less pitchy, or pitchy- 
testaceous. L. 2-2} mm. 
Male with the rostrum shorter than in female, the head broader, and 
the eyes larger, and the antenne more plainly testaceous at base; the
