1. Lepidobaris acnisti, sp.n. (Tab. XX. figg. 17, 17 a, 4, 3.) 
Elongate, opaque, the inner half of the elytra, the median line of the prothorax, the abdomen, and meta- 
sternum shining, black, the antenne and tarsi in part or entirely ferruginous; the rostrum with the 
basal half (¢) or base (2) fulvo-squamose; the prothorax variegated with stout, erect, intermixed 
velvety-black and fulvous scales, the black ones clustered into two sinuous lines along the middle of the 
disc ; the elytra with irregular, coalescent, oblong patches of broad, imbricate, intermixed velvety-black, 
fulvous, and whitish scales extending down the disc from a little below the base to the apex ; the legs 
and the under surface of the prothorax fulvo-squamose, the rest of the ventral surface (except in the ¢ ) 
almost bare. Head closely punctate; rostrum ( ¢ ) stout, about as long as the head and prothorax, densely 
punctate, and opaque, ( 2) a little longer and more slender, flatter, very sparsely punctate, and bare from 
near the base. Prothorax strongly transverse, gradually narrowing from the base, constricted in front ; 
densely, finely punctate, except along the smooth central line. Elytra long, transversely depressed on 
the dise before and beyond the middle, the humeri rounded and slightly tumid; finely punctate-striate, 
the interstices broad, finely, confusedly punctate, flat, the fifth swollen into an oblong hump at its point 
of termination. Pygidium densely punctate. Beneath coarsely and closely, the ventral segments very 
sparsely and finely, punctate, 1 and 2 with a hollowed, closely punctate, densely fulvo-pilose space down 
the middle in the ¢, and 5 with a truncated prominence at the centre of the apical margin, on either 
side of which is a semicircular emargination, in this sex. Prosternum suicate, the sulcus deep and 
limited by a sharp ridge on each side anteriorly, shallow and V-shaped between the coxe, the latter 
hollowed within and separated by less than half their own width. Legs rugosely punctate, 
Length 4-54, breadth 14-23 millim. (d 2.)

Sent in abundance by the late P. Biolley, who found it on the leaves of the 
“ ouitite” (Acnistus arborescens, Schlecht.), a shrub of the order Solanacee. A 
remarkable form, with the general facies of an Ambates. 
2. Lepidobaris opacipennis, sp. n. (Tab. XX. figg. 18, 18a, ¢.) 
Oblong, opaque, the prothorax, metasternum, and abdomen, and sometimes the sutural region of the elytra 
also, shining, black, the antenne and tarsi ferruginous; the rostrum fulvo-squamose at the base; the 
prothorax thickly clothed with coarse, semierect, intermixed velvety-black, fulvous, and whitish scales, 
the black scales almost entirely condensed into two large triangular patches on the basal half; the elytra 
with a dense elongate patch of coarse velvety-black scales at about the middle of the second and third 
interstices and an oblong black spot at the apex of the fifth, the space between the median patch and the 
suture set with a few broad, triangular, fulvous or whitish scales, the vestiture of the rest of their 
surface in great part blackish and inconspicuous ; the under surface almost bare. Head finely punctate ; 
rostrum (¢ ) stout, a little longer than the head and prothorax, gibbous at the base, opaque, and densely 
punctate, (Q) strongly arcuate, longer, and smoother. Prothorax short, abruptly constricted in front, 
appearing angulate at the sides anteriorly ; densely, finely punctate. LElytra moderately long, flattened, 
transversely depressed on the disc before and beyond the middle, and compressed at the sides below the
