One example, S. Paulo, Upper Amazons. It is possible, not- 
withstanding the great difference in colour, that it may be but 
a local variety of A. lignicola. 
Two other species of AnisopoduSy in addition to the eleven 
here enumerated, have been described, namely, A. curvilineatus 
(White, Brit. Mus. Cat. ii. p. 350, pi. 9. f. 1) of South Brazil, and 
L. prolixus (Erichson, Consp. Ins. Peruana, p. 145) of Eastern 
Peru. The latter is the largest species at present known, and 
seems to be closely allied to A. arachnoides. I add a description, 
at the foot, of a fourteenth species*. 
Genus Lepturges, nov. gen. 
Body depressed, oblong, elliptical or elongate, free from irre- 
gularities or tubercles on its surface, and clothed with fine, 
prettily variegated tomentum. Antennae long and hair-like, 
sparsely clothed with short, stiff hairs ; the basal joint greatly 
elongated, gradually thickened from the base, the club thus 
formed being waved or not in its outline beneath; the remaining 
joints (except the second) very slender. Thorax trapezoidal, 
depressed, the lateral spines placed close to the hind angles, or 
at a short distance from them. Elytra free from centro-basal 
ridges or tubercles, more or less truncated at the tip, except in 
rare instances, where they are entire. Abdomen with the ter- 
minal segment slightly elongated in the females, the dorsal 
plate obtusely pointed at the tip, the ventral truncated or scarce 
perceptibly emarginated ; in the males the same terminal seg- 
ment has both its ventral and dorsal plates entire at the tips. 
Legs moderate in length, the thighs moderately clavate, and 
the basal joints of the tarsi elongated. 
This group, which comprises a large number of small Leiopo- 
dine Longicorns of Tropical America, is so closely allied to the 
European genus Leiopus that I have great hesitation in sepa- 
rating it. All the species, however, differ from the European 
Leiopus nehulosus (the type of the genus) in the shape of the 
thorax, and in the antennse having very slender and elongated 
joints more or less clothed with stiff hairs. The thorax has, in 
nearly all the species, a trapezoidal outline, the lateral spines 
being placed very near to, or coincident with, the hind angles, 
the surface depressed, and the sides widening from the head 
* A. canus. — Oblongus, planus, tomento denso canescente vestitus. An- 
tennse rufescentes, articulis apice nigris. Thorax punctatus, antice 
nigro bivittatus, spinis lateralibus tenuibus porrectis. Elytra lateribus 
parallelis, prope apicem subito attenuata, dorso insequalia, medio for- 
titer depressa, carinis lateralibus acutissimis, apieibus longe mucro- 
natis ; canescentia, maculis minutis nigris sparsa, quarum duabus di- 
stinctioribus prope apicem. Pedes nigricantes, femoribus tibiisque 
dimidiis basalibus rufis. Femora postica (maris?) elongata, subito 
clavata. Long. lin. Hab. Brasilia meridionalis. Coll. Bakewell.
