divergent, with a broad, acute tooth at the base) points to an 
affinity with the Caliianee ; and as I think this feature outweighs 
in importance the dissimilarity of general form and facies, I have 
placed the genus in the Callianse group, rather than amongst the 
Pogonocherin^e, with which it agrees in some points. The body 
is elongate-oblong, narrowed behind, depressed above, and beset 
with short bristles. The head is short, the crown, in profile, not 
forming an angle with the forehead, and the face very little pro- 
longed and narrowed below the eyes, which latter are large and 
convex. The thorax has a distinct acute tubercle on each side 
in the middle. The elytra are singly rounded at the apex. The 
antennae are half as long again as the body, filiform, and setose, 
the basal joint short and forming an oblong club, the third 
joint a little longer than the fourth, and the rest very gradu- 
ally decreasing in length. The legs are moderately long, the 
thighs slightly clavate ; the tarsi moderately short, with the claws, 
as before mentioned, armed each at the base Vvdth a large, acute 
tooth. 
Eumathes Amazonicus, n. sp. 
Eu. elongato-obloiigiis, supra planus, setosiis, viridi-cinereus, obscure 
fusco maculatus ; elytris dense et confuse punctatis ; maris tar- 
sorum posticorum articuio primo valde elongato. Long. 5-5-| lin. 
Head coarsely punctured, clothed with grey, pubescence. 
Antennse dingy grey. Thorax irregularly punctured on its sur- 
face, light-greenish ashy, obscurely varied with dusky ; lateral tu- 
bercles small, acute. Elytra slightly narrowed behind, plane 
above and free from costse, rather thickly but irregularly covered 
with small punctures, especially on the basal half, and clothed 
with short bristles ; pale-greenish ashy, obscurely varied with 
dusky spots of various sizes. Body beneath and legs clothed 
with ashy pubescence. First joint of the hind tarsi in the male 
as long as the remaining joints taken together. 
Ega. I am indebted to Mr. Alexander Fry for pointing out 
the differences between this species and its near relative Eumathes 
undatus (Pascoe) of Southern Brazil. The great length of the 
basal joint of the posterior tarsi in the male, and the closer punc- 
tation of the elytra, are the chief distinguishing characters. 
Genus Chalcolyne, nov. gen. 
Closely allied to Gryllica, Thoms. (Classif. des Cerambyc. 
p. 120), but differs in the thorax being armed on each side with 
an acute spiniform tubercle. Body oblong, clothed with short, 
stiff hairs; elytra snbtrigonal, rounded at the tip. Head with 
long, slightly retracted face ; mouth projecting ; palpi elongate, 
pointed; eyes ample both above and beneath, and nearly ap-
