LONGICORNIA. 309 
Of described genera of Cerambycide this genus comes nearest to Lissozodes; but it 
is also closely allied to Ozodes and to Sthelenus, which last is placed by Lacordaire in 
the neighbourhood of the Molorchides, a widely different group. In Lissozodes the 
anterior haunches are salient, but not to the extent reached in Eucharassus. The 
antennee in all the genera, and in others still undescribed belonging to the same group, 
are similar in length and form, and in the proportions of the joints; but Hucharassus is 
distinguished for the remarkable clean-cut groove from the base to the apex of the third 
joint and the double groove (one on each of the compressed sides) of the fourth and 
following joints. The antenne and legs are not clothed with long and abundant hairs, 
as in Lissozodes and Ozodes. | 
1. Kucharassus dispar. (Tab. XXI. fig. 18, ¢.) 
d. Fusco-niger, thorace vitta mediana irregulari (medio interdum interrupta) scutelloque rufis; elytris 
pallidius fuscis, humeris et vittis utrinque duabus abbreviatis nigris, 14 a basi usque prope medium, 24 ab 
humeris usque prope apicem ; mesosterni epimeris, metasterno et abdomine rufis ; thorace longiori, disco 
utrinque confertim asperato-punctato subcalloso, subtus et lateribus confertissime rugoso-punctato. 
Q. Caput, antenne et pedes nigri; elytris sicut in ¢, thorace toto, scutello corporeque subtus (capite solum 
excepto) rufis; thorace multo breviori, subtilius ruguloso-punctulato, tuberculato, subtus fere levi 
nitido. 
Long. 5-8 lin. ¢ 9. 
Hab. Panama, Volcan de Chiriqui (Champion, Trétsch). 
Same habits as Aphysotes. 
RHOPALOPHORA (p. 61). 
Rhopalophora cupricollis (p. 62). 
To the localities given, add :—Mexico, Ventanas (Forrer), Cordova (Sallé, Hoge), 
Cerro de Plumas, Merida in Yucatan (Hoge), Chiapas (Sal/é). | 
In the great majority of the specimens the thorax is red beneath; this is not there- 
fore a distinctive character of R. rubecula; the latter differs from F. cupricollis more 
constantly in having a rather broad black dorsal vitta on the thorax. In K. cupricollts 
the surface of the thorax varies in being spotless, having a central dusky spot, a short 
dark line, or a continuous narrow dorsal line. The last mentioned approaches extremely 
near R. rubecula. 
Rhopalophora lineicollis (p. 62). 
To the locality given, add :—Muxico, Ventanas (Forrer), Cordova (Sallé), Almolonga 
(Hoge). 
3 (a). Rhopalophora longipes. |
