Hab. Khasia (coll. Rothney). 
Scape of antenne, head, median segment and sides of ab- 
domen thickly covered with silvery pubescence; the tarsi on 
the underside are thickly covered with stiff pubescence and 
bear, on the apices of the joints, stiff spines. Sides of the head 
in front coarsely rugosely punctured, the punctures running 
into reticulations; the vertex closely punctured; the outer 
orbits bear shallow, scattered punctures. Apex of clypeus 
roundly, but not deeply, incised; the part between the antenne 
taised, transverse belaw. Pro- and mesonotum rugosely punc- 
rured, the punctures running into reticulations. The scntel- 
lum is more widely reticulated; it is flat above; at its base, 
laterally, the mesonotum forms two larze rounded masses, op- 
posite the tegule. The base of the median segment is flat, 
smooth ; on the middle are five stout, longitudinal keels; the 
outer side is deeply foveate. ‘lhe apex of the segment has on 
the top a large, deep, fovea, rounded behind, transverse below ; 
below this are 2 or 3 irregular reticulations; the sides project 
largely and have, shortly beyond the middle, a large, some- 
what triangular tooth. Propleure irregularly reticulated be- 
hind ; the apex below and the lower part depressed, the meso- 
pleure deeply and widely depressed, smooth, obscurely aud 
finely striated in the middle. Metapleure regularly reticulated. 
Abdomen smooth and shining at the base, the 2nd segment 
broadly in the middle and the others entirely and more strongly 
punctured.
