Prothorax somewhat narrower than the posterior margin of 
the head, the apotom separated off by a distinct constriction. 
Meso- and ineta-notum naked (the rest of the body covered with 
stiff hairs.) 
Legs without peculiarities (so far as I could ascertain from 
these dry specimens). Front tarsi with the normal oval metatarsus, 
convex above,*for use in spinning. 
Extremity of the abdomen; loth tergite divided longitudi- 
nally ; the right half produced into a long pointed process, the left 
with a short round termination. The appendage of the gth sternite 
(penis ?) projects straight back and appears to be bifid ; its anterior 
portion is hidden by the middle part of the loth tergite. Basipodite 
of the left cercus flattened, produced inwards ; the first joint of the 
left cercus strongly club-shaped, posterior half produced inwards 
and toothed on that side ; the second joint short, thick and 
cylindrical. (It is difficult to determine the precise structure of the 
extremity of the abdomen in dry specimens). 
Colour. — Dark brown, meso and meta-notum and parts of the 
legs lighter; the first segments of the antennae yellowish brown. 
Dimensions. — Specimen i — length ii| mm. 
Specimen 2 — length 10 mm. 
Wings the same size in both specimens — length ii-io mm., 
breadth 2|-2j mm. 
Habitat. — Western Australia. Captured in Perth by Mr. G. 
H. Hardy, now at the Tasmanian Museum, Hobart. They flew 
into a room in company with several other individuals attracted by 
the light of a lamp in June, 1912. 
Remarks. — This species does not agree with the diagnosis of 
the genus Oligotoma given in either of the Monographs (those of 
Krauss and Enderlein). Yet, there is no doubt that O. hardyi is an 
Oligotoma. 
It differs from Enderlein’s diagnosis in the strong development 
of the median and the posterior branches of the radial ramus, and 
in the absence of a process on the left half of the lolh tergite. From 
Krauss’ diagnosis it differs in possessing teeth on the much-thick- 
ened first joint of the left cercus. O. heymonsi, End., also differs 
from this diagnosis in having the same organ toothed, whilst in 
0 . greeniana, End., the left process of the loth tergite is also 
absent.
