and about 13 from apex; base subtruncate or slightly 
sinuate; apex subtruncate, with anterior angles very 
slightly advanced; sub-basal impressions in form of deep, 
somewhat elongate foveae, each connected with the margin 
posteriorly by a deep, curved impression ; disc with median 
line light, transverse impressions obsolete, surface impunc- 
tate.. Elytra 1/5 or 1/4 wider than prothorax, not or moder- 
ately narrowed anteriorly (variable), with sides subparal- 
lel or slightly arcuate at middle, sinuate before apex, then 
rather narrowly and almost conjointly rounded; basal mar- 
gin either entire and conspicuously lobed or interrupted at 
1st, 3rd, and 5th intervals (variation individual, not geo- 
gi'aphical), approximately rectangular and strongly ele- 
vated at humeri ; striae rather deep, entire, impunctate, but 
finely granular at bottom; intervals alternately wide and 
narrow (1, 3, 5, and 7 wide), moderately convex on disc, 
more so laterally and apically; 3rd interval 2, 3, or 4 punc- 
tate, the punctures somewhat irregular in position as well 
as number; 8th and 9th intervals narrow and convex; frag- 
ments of a very narrow 10th (submarginal) interval post- 
eriorly. Prosternal process not margined, declivity flat, 
without setae; metepisterna short; sides of sterna not much 
punctate, but sides of abdomen especially anteriorly ex- 
tensively punctate, with the segments more or less im- 
pressed near sides. Fifth segment of tarsi without acces- 
sory setae below. Male with anterior tarsi a little dilated, 
first 3 segments biseriately squamulose; $ with 1, $ with 
2 setigerous punctures each side last ventral segment. 
Length 14-16.5; width 4. 1-5.0 mm. 
Holotype S (M. C. Z. Type No. 29,016) and 3 paratypes 
from Malanda, Atherton Tableland, North Queensland, 
Nov. 7 and 8, 1950, collected by Dr. W. L. Brown in rotten 
logs in rain forest; and also the following additional para- 
types : 3, Millaa Millaa, Atherton Tableland, about 2,500 ft. 
alFtude, April, 1932; and 1, Lake Barrine, Atherton Table- 
land, about 2,300 ft. altitude, April, 1932. 
This, the first Leiradira to be recorded from North 
Queensland, is very distinct from all species previously as- 
signed to the genus. The alternation in width of the elytral 
intervals is alone enough to distinguish it from, for ex- 
ample, L. auHcollis Cast, and all other known species of the
