Opatrum dispersum, n. sp.’ 
Moderately elongate, subparallel, not very convex, rather 
narrow, pitchy-brown, opaque, somewhat sparsely clothed with 
moderately long, appressed yellowish-cinereous hairs, which on 
the elytra form a very irregular treble series on each of the 
interstices. Head somewhat exserted, densely punctured, the 
epistoma very deeply emarginate and confounded with the front, 
the eyes rather large and completely divided, the orbits narrow 
and rounded off behind ; antennez scarcely reaching the base of 
the prothorax, joints 8—10 transverse ; prothorax convex, twice as 
broad as long, rather feebly arcuate-emarginate in front (sub- 
truncate if viewed from above), strongly bisinuate at the base, 
moderately rounded at the sides, widest a little before the base, 
the hind angles subrectangular, the anterior angles rather obtuse, 
the surface densely, rather finely punctured ; elytra about four 
times the length of, and scarcely wider than, the prothorax, 
subparallel in their basal half, finely and lightly punctate-striate, 
the interstices almost flat, finely and closely punctured, the 
punctures slightly muricate ; tarsi thickly clothed with long silky 
hairs beneath, the anterior pair simple; anterior tibie slender, 
gradually widening outwardly, the outer apical angle sharp. 
Length 64—7, breadth 2?—3 mm. 
Hab. N. W. Australia-—Port Darwin. 
Two examples, apparently including both sexes; three 
others have also been sent to me by Mr. Walker from 
Damma Island. This insect is perhaps generically 
distinct from Opatrum, the tarsi being clothed with 
silky hairs beneath; but in the present imperfect state 
of our knowledge of the somewhat numerous Australian 
species of this group, it is inadvisable to separate it. 
The punctures of the striz are fine and very closely 
placed, not coarser than those of the interstices. It is 
not impossible that this insect may be referable to O. 
seriatum, Boisd., from Radack ; the description of that 
species, however, is wholly inadequate, consisting of 
seven words only. 
Opatrum vagabundum, n. sp. 
Moderately elongate, rather narrow, convex, subparallel, black 
or brownish black, opaque, sparsely clothed with short brownish 
hairs, which are subserially arranged on the elytral interstices. 
Head somewhat exserted, densely, rather coarsely punctured, the 
epistoma very deeply triangularly emarginate and confounded
