MACROMERUS. 509 
7. Macromerus albofasciatus, sp.n. (Jab. XXV. figg. 8, 8a, 2.) 
Oblong-ovate, shining, black; thickly clothed with small scales, the prothorax with a narrow median vitta 
and the under surface (except at the base), the elytra with a broad fascia below the base, extending 
downwards over the lateral portion of the metasternum, and a large broad oval patch before the apex of 
each, and the second ventral segment, white, the rest of the vestiture of the upper surface dark brown, 
that of the legs sparse and cinereous. Head rugulosely punctate, the eyes very large and narrowly 
separated ; rostrum subcylindrical, curved, rugulosely punctate and carinate at the base, and for the rest 
almost smooth, the antennze inserted at about one-third from the base, joint 2 of the funiculus very 
elongate. Prothorax rather convex, slightly broader than long, rapidly narrowing from a little behind 
the middle, the sides becoming parallel towards the base; closely punctate, each puncture followed by 
a smooth crescentiform elevation, the interspaces also very minutely punctate, the disc canaliculate down 
the middle. Elytra seriate-punctate, the interstices almost flat, punctulate, and obsoletely granulate, the 
disc depressed along the suture anteriorly. Beneath with scattered coarse punctures intermixed with 
minute ones. Femora clavate, unidentate. 
Length 11, breadth 44 millim. (@.) 
Hab. Nicaracua, Chontales (Richardson); Costa Rica (Van Patten). 
Two specimens. ‘The white markings in this insect are very sharply defined, both 
above and beneath, as in various species of Ambates and Peridenetus. 
8. Macromerus leuconotus. (Tab. XXV. figg. 9, 9a, 6, ¢; 10, 2.) 
9. Macromerus leuconotus, Boh. in Schénh. Gen. Cure. vill. 1, p. 357°. 
Oblong-ovate, black, the antenne fusco-ferruginous ; mottled above with pale brownish, white, and dark 
brown scales, the white scales almost confined to the base of the prothorax and the depressed space on 
the disc of the elytra, the scales on the anterior half of the prothorax almost wholly dark brown, with a 
few fulvous ones intermixed; the vestiture of the under surface close and whitish, that on the legs 
similarly coloured. Head densely, rugulosely punctate between and above the eyes, the latter very large; 
rostrum subcylindrical, rugulose at the base, almost smooth in its outer half, the antenne inserted at the 
middle in the ¢ and at about one-third from the base in the 2, joints 1 and 2 of the funiculus subequal 
in length. Prothorax a little broader than long, rapidly narrowing from the middle forwards, the sides 
parallel behind; sparsely punctate, each puncture followed by a crescentiform elevation, the interspaces 
minutely punctate, the disc sharply carinate. Elytra coarsely seriate-punctate, the interstices more or 
less raised and granulate, the disc broadly depressed along the suture anteriorly. Beneath with coarse 
scattered punctures, the ventral segments 3-95 much smoother. All the femora strongly clavate in both 
sexes. Anterior tibie with a sharp median tooth on the inner side, and the two basal joints of the 
anterior tarsi broadly dilated and clothed with long projecting hairs, in the ¢. 
Length 81-83, breadth 33-37 millim. (3 @.) 
Hab. Panama, Chiriqui (ex Boucard), Bugaba (Champion). — CotomBia! (Mus. 
Brit.: 3). 
One pair, the male somewhat worn. ‘This species has the anterior femora strongly 
clavate and similarly formed in both sexes, the insect differing in this respect from 
its allies. 
If it is correctly identified, Boheman’s description must have been taken from a 
female.
