Opatrum villigerum. 
Opatrum villiger, Blanch., in Dumont d’Urville’s 
Voyage au Pole Sud, iv., Ins. p. 154, t. 10, 
fies £0; 
Hab. S. Australia—Port Adelaide. 
Two examples, perhaps belonging to this species, the 
original specimens of which were obtained at Raffles 
Bay. 
Opatrum torridum, n. sp. 
Rather elongate, subparallel, moderately convex, black, opaque, 
sparsely pubescent, and usually thickly covered with an adherent 
earthy coating. Head broad, thickly punctured, the epistoma very 
deeply emarginate, the sides of the front broadly, obliquely, sub- 
angularly dilated, and extending more than half way across the eyes, 
the latter rather large ; antenne almost extending to the base of the 
prothorax, the penultimate joints transverse ; prothorax strongly 
transverse, not very convex, moderately explanate at the sides, 
broadly and deeply emarginate in front, strongly bisinuate at the 
base, which is also feebly emarginate in the middle, the sides 
moderately rounded, obliquely converging in front, and slightly 
sinuous behind, the anterior angles sharp and prominent, the hind 
angles sharply rectangular, the surface thickly and finely punc- 
tured, the interspaces densely, very minutely punctate and also 
finely granulate ; elytra about four times as long as the prothorax, 
and a little wider than it, subparallel in their basal half, and with 
subrectangular somewhat prominent humeri, moderately deeply, 
rather finely punctate-striate, the interstices almost flat, densely, 
very minutely punctured and also finely granulate ; anterior tibize 
gradually widening outwardly, their outer apical angle sharp ; 
anterior tarsi sparsely clothed with rather coarse hairs beneath ; 
body fully winged. Length 8i—83, breadth 3}—4 mm. 
Hab. N.W. Australia—Adelaide River. 
Two examples, apparently male and female. This 
species (of which I have also received a specimen from 
the Kev. T’. Blackburn) closely resembles some of the 
common Kuropean forms, such as O. (Gonocephalum) 
rusticum, Oliv. As is frequently the case in this genus, 
the sculpture is almost completely hidden by an adherent 
earthy coating; when this is removed, the minute 
punctuation and the granular elevations of the inter- 
stices of the elytra are easily seen.
