angles of median part forming strong teeth ; clypeal wings al- 
most as prominent as teeth of median part, with outer angles 
narrowly rounded, separated from supra-antennal plates by 
distinct notches; eyes small, only slightly more prominent 
than supra-antennal plates, but not enclosed behind ; 2 
supra-orbital setae each side in all specimens; front not 
distinctly separated from clypeus, only slightly convex, with 
frontal sulci recurved; occiput without transverse impressed 
line; middle of front and usually sides and vertex also, but 
not occiput, closely punctate. Prothorax with lateral margins 
entire or nearly so, but in some specimens becoming vague 
or obsolete just before reaching basal margin; without 
longitudinal foveae on episterna; about as long as wide, 
with sides approximately parallel; front margin distinctly 
emarginate (as seen on a line perpendicular to pronotum) ; 
posterior angles broadly rounded ; anterior angles acute 
except finely blunted (as usual) ; disc with median line fine, 
but distinct, anterior transverse impression more or less 
obsolete, sub-basal lateral impressions long, reaching to 
slightly in front of middle; surface of disc finely, sparsely 
punctulate and with a few irregular transverse strioles; 
posterior declivity vaguely rugose. Elytra parallel, hardly 
1/20 wider than prothorax, truncate at base; 4 inner striae 
free at base, 5th united with 6th; subhumeral carina short, 
not very distinct; striae almost entire, but vague or obliter- 
ated just before apex, punctulate; intervals nearly flat, 3rd 
with usual 4 distinct setigerous punctures on outer edge, 
surface of intervals with some fine, irregular, transverse 
strioles, but not distinctly punctulate. Prosternal process 
very narrow (attenuate) between anterior parts of coxae; 
prosternal episterna and lower surface of head and abdo- 
men, especially at sides, with distinct isodj' ^.metric micro- 
sculpture; body virtually impunctate below. Anterior 
femora rather strongly lobed below; anterior tibiae each 
strongly 4-dentate externally, and with upper internal 
spine somewhat curved and thickened; middle tibiae each 
with a spur about 1/3 from apex externally. Length about 
6.3-7.0; width about 1.7 mm.
