bus subangulatis ; elytris obscure piceis, distincte punctatis, 
utrisque spatio basilari elevato, fere impunctato. 
Long. 4 lin. 
Hab.—Madagascar. 
Head subquadrate; epistome thickened, transversely 
sulcate just behind the anterior margin, the sulcation nar- 
rowly interrupted in the middle; anterior border notched 
on either side close to the outer angle ; encarpz separated 
from the front by a deep transverse depression, trigonate, 
contiguous above, separated below by the apex of the epi- 
stome ; antenne rather more than half the length of the 
body, moderately robust. Thorax more than twice as 
broad as long; sides distinctly margined, bisinuate behind | 
the middle, the latter obtusely angulate; posterior angles 
produced, acute, anterior obliquely truncate ; upper sur- 
face coarsely but not closely punctured, transversely exca- 
vated just behind the anterior border; basal groove more 
distinct than in Xenaltica Murray?, extending the whole 
length between the longitudinal sulci, the latter ill-defined. 
Elytra broader than the thorax, convex, distinctly and 
somewhat strongly punctured, the punctures less coarse 
than those on the thorax; each elytron depressed along 
the suture and also transversely below the basilar space, 
the latter distinctly raised, nearly impunctate; humeral 
callus thickened. 
Genus EUPHITREA. 
Corpus rotundatum, convexum. Caput breve; antennis 
1l-articulatis, filiformibus, articulo secundo brevi, tertio 
illo vix longiori ; oculis modice prominulis; encarpis ob- 
liquis, non contiguis; carind obsoleta. Thorax transversus. 
Elytra thorace latiora, confuse punctata, limbo inflexo 
concayvo. Pedes modice robusti; coxis anticis vix elevatis; 
femoribus posticis modice incrassatis; ¢ibiis posticis non 
aut vix canaliculatis, apice spina acut& armatis; ¢2bzis 
anticis quatuor muticis; wnguiculis appendiculatis. _ Pro- 
sternum coxis fere equialtum, dorso canaliculatum, apice 
transversim dilatatum; acetabulis anticis integris. Meso- 
sternum breve, erectum, metasterni apice occultum. Meta- 
sternum inter mesocoxas ad prosterni marginem produc- 
tum.
