LOXANDRUS CALATHOIDES, n. sp. — Elongato-ellipticus, nigerrimus, 
lete wridescens, labro, palpis, antennarum basi, tarsisque piceo-ruyis ; 
thorace sub-quadrato, ad basin elytris paulo angustiori, lateribus paululum 
rotundatis, angulis posticis sub-obtusis, haud prominulis, supra, totidem levi, 
basi utrinque foved elongata profundd impresso ; elytris profunde striatis, 
striarum fundis subtiliter punctulatis ; subtus mesosternt episternis punctatis, 
Long. 44 lin. 8. 
Very closely allied to Z. /evicollis, differing chiefly in the conspi- 
cuously broader thorax, not perceptibly narrowed behind, and in the 
deeper elytral stria.

LoXANDRUS FULVICORNIS, n. sp.—LHlongato-ellipticus, nigerrimus, 
politus, supra iridescens, antennis, labro, palpis, tarsisque piceo-fulvis, 
pedibus piceis ; thorace elytris angustiori, sub-quadrato, postice paululum 
angustato, angulis posticis prominulis, sub-rectis, supra basi utrinque 
Soved elongata, profunda, grosse punctatd impresso, juxta angulos posticos 
impunctato ; elytris punctulato-striatis, interstitiis sub-planis, apicem 
versus angustis, convexis. Long. 45 lin. @. 
The elytra in this species are rather less deeply-striated, but the 
strie are punctulated as in ZL. politissimus, the strie becoming much 
deeper and the interstices more convex towards the apex.

LoxanDRUS XANTHOPUS, n. sp.—WMinor, elongato-oblongus, piceo 
niger, sub-iridescens, labro, palpis, antennarum bast, pedibusque testaceo- 
Jlavis ; thorace elytris multo angustiori, antice rotundato-dilatato, postice 
sinuato-angustato, angulis posticis prominulis, rectis, marginibus reflexis 
rufo-piceis, supra basi utrinque foved elongata, profundd, intus plagiatim 
punctata, impresso; elytris profunde simpliciter striatis; subtus metasterno 
solim grosse sparsim punctato. Long. 3—3} lin. 8 9. 
Differs from all the preceding species in its less elliptical and more 
oblong general form, and in its pitchy colour, with the flattened reflexed 
margins of the thorax, and the suture of its elytra behind more or less 
pallid-piceous. The thorax is very distinctly narrowed behind, and si- 
nuated before the hud angles, which are prominent and pointed. The 
punctures at the base -f the thorax are confined to a patch on the 
inner side and at the bottom of the deeply sulcated fovea. 
Generally distributed throughout the Amazons, and common.
