carinate, straight anteriorly, and behind it are two impressions 

 witli rugose surfaces, and the space between them isrugose; 

 the thorax, marginal stria very fine, with two well-marked 

 lateral striae; the inner stria continues behind the head and is 

 feebly sinuous behind the eyes, at the anterior angle the 

 interstice is punctured and there is a border-line of points 

 along the base; the elytra, striae deep and crenulate, outer 

 humeral short and basal, inner humeral and 1—3 dorsal com- 

 plete, 4 indistinctly shortened at the base, 5 apical and 

 nearly dimidiate, sutural is bent and clearly abbreviated at 

 the base ; the pygidia are densely punctate ; the mesosternum 

 anteriorly is straight and marginate ; the anterior tibise are 

 3-dentate, the apical tooth being very robust; this last cha- 

 racter is common to all the species of Exorliabdus, and it is 

 also seen in Uister fossa, vadutus, and others. 



The general sculpture of this species resembles that of 

 cvneas ; there is no band of thoracic punctures, but in one 

 specimen there are a few irregular points at the anterior 

 angle.

Breviter ovalis, convexiusculus, niger, nitidus ; fronte stria antice 

 sinuata ; pronoto lateribus conspicue rugoso-punctato ; elytris 

 striis fortibus crenatis, 1-4 integris, 5 dimidiata, suturali basi 

 abbreviata ; propygidio pygiclioque vix dense punetatis ; meso-

Shortly oval, rather convex, black, and shining ; the head 

 obscurely punctulate above, stria well marked and sinuous 

 anteriorly ; the thorax, inner lateral stria complete, clear and 

 crenulate behind the. head, laterally it is irregular owing to 

 the rugose sculpture, the outer stria ceases behind the eye 

 and is shortened before the base, the sides are strongly and 

 rugosely punctured, including the interstice ; the elytra, 

 outer humeral stria short, not reaching the base, and ceasing 

 at a point opposite to where the inner humeral begins, inner 

 humeral apical and dimidiate, striae 1-4 deep and complete 

 with crenulate edges, 5 apical and dimidiate, sutural well 

 shortened anteriorly and bent, turning away from the suture 

 at both ends, the interstices, especially those of the inner 

 humeral and the first and second striae are rugosely punc- 

 tured on the apical half, and the apical border is irregularly 

 rugose ; the pygidia are rather closely punctate, the pygidium
