22 * LONGICORNTA. 
Hab. Mexico, Plan del Rio (Hége). 
A small and slender species for this genus, resembling the typical Eburodacrys. A 
distinguishing character is the absence of antero-lateral tubercles from the thorax, 
although the lateral spine is well-developed, conical, and acute. ‘The usual exterior 
spines of the hinder femora are quite obsolete. The geminated eburneous spots are 
closely contiguous, both basal and median pairs, and are narrowly margined with brown. 
10. Eburia laticollis. 
Obscure rufescenti-fusca, subtilissime pubescens et erecte pilosa; antennis scapo (¢) brevi, mox a basi in- 
crassato; thorace magno, subrotundato, spinis lateralibus minutissimis,.tuberculis duobus disci solum 
nigris politis ; elytris apice breviter bispinosis, supra crebre punctulatis punctisque majoribus intermixtis, 
lineolis brevibus utrinque quatuor geminatis sed haud contiguis, duabus basalibus brevissimis interiore 
longiore, duabus medianis paullo longioribus, in nebula nigra sitis, interiore multo minore ; femoribus 
quatuor posticis spinis brevissimis vix conspicuis, equalibus. 
Long. 83 lin. ¢. 
Hab. Muxico (Hegewisch). 
Although agreeing in the sculpture and clothing of the elytra with L. brevispinis, 
this species has quite a different facies, due chiefly to its broad rounded thorax. The 
short thick form of its antennal scape is a good specific character.

The elytra, according to the description, have each three successive and detached

This genus comprehends all those species, formerly included in Eburia, which have 
grooved antenne. ‘They are generally of smaller size and more slender form than the 
Hburie, and are about equally numerous, though fewer have yet been described. They 
are, however, more generally continental and tropical than the Eburie, only one being
