Sub-Family MELOLONTHIDES. 
151. M^chidius fissiceps,. n.sp. 
Chocolate-brown, sub-opaque, densely covered with rather coarse 
variolose punctures, each puncture bearing a small light coloui'ed 
scale. Head with the clypeus large, projecting laterally in front 
of the eyes in an acute point, narrowed and biemarginate from 
thence to the apex, deeply and narrowly emarginate at the apex, 
prominently and sub-acutely pointed on each side of the emargina- 
tion, and with the margin rather broadly reflected. Thorax twice 
as wide as long ; the antei’ior angles acute and slightly produced, 
the sides very slightly rounded, the widest part being about one 
third from the base, the anterior third of the sides slightly crenu- 
late, the posterior angles nearly rectangular. Elytra rather wider 
than the thorax at the base, and three times the length, a little 
ampliated, and broadly rounded at the apex, with on each elytron 
about twenty very regular I’ows of rather oblong variolose raised 
punctures, each furnished with a minute setiform scale, the inter- 
vals quite smooth. The anterior tibiie are rather strongly bidentate 
at the outer apex, with a minute tooth about the middle. 
Long. 5, lat. 2|- lines. 
152. MiECiiiDius Froggatti, n.sp. 
Dark brown, sub-opaque, of oblong-ovate form, punctate and 
scaly. Head roughly punctate, the clypeus reflected in front and 
emarginate but not deeply, the angles in fi'ont of the eyes not very 
prominent as in the last species, and a distinct transverse swelling 
extends along its middle. The thorax is moi’e finely punctate 
than in M. fissiceps, the anterior angles are more obtuse and 
produced, the sides slightly but regularly rounded, the posterior 
angles rectangular, and the base slightly rounded. Elytra not 
wider than the thorax and about three times the length, strongly 
punctate in numerous rows, the interstices all very narrow, but 
the alternate ones showing distinct lines, the i*ow from the humeral 
angle costiform for a third of its length, the a}>ex of the elytra is
