fine and transverse on pronotum and elytra but not distinctly visible 
at 100X. Head, .86 and .84 width prothorax (in cf$ measured); 
eyes large, forming c. right angles with neck; antennae with middle 
segments scarcely longer than wide; frontal sulci moderate, irregular, 
ending before mid-eye level; 2 setae over each eye. Prothorax: width/ 
length 1.44 and 1.46; base/apex 1.01 and 1.05; disc with middle line 
distinct, transverse impressions vague, baso-lateral impressions slight; 
2 pair lateral setae present. Elytra 2/3 wider than prothorax (E/P 
1.68 and 1.66) ; impression behind puncture-triangle (near margin 
at 2/3 or 3/5 of elytral length) wide, flat-bottomed; discal striae 
indicated, first 2 or 3 slightly impressed, irregular but not distinctly 
punctate; intervals not or very sparsely punctulate, 3rd 3-punctate 
with anterior and middle punctures near 3rd stria and posterior one 
near 2nd stria. Inner wings fully developed. Power surface , legs , 
and secondary sexual characters normal; cf front tarsi scarcely 
dilated, 3 segments briefly biseriately squamulose. Measurements : 
length c. 3-4; width c. 1.4 mm. 
Holotype cf (M. C. Z. No. 30, 524) and 9 paratypes all from 
Kuranda, near Cairns, North Queensland, c. 1000 ft., Feb., 1958, 
taken by myself in piles of dead leaves under the heads of felled trees 
on the edge of rain forest. Also 1 specimen, not a type, from Rocky 
River, Cape York Peninsula, North Queensland, (late May or early 
June) 1958, also taken by myself. 
See preceding key for distinguishing characters of this new species. 
Perigona (Trechicus) picta n. sp. 
Figure 2 
Form as figured (Fig. 2), stouter than nigriceps or dorsata , with 
wider and more rounded prothorax and narrower head ; piceous black, 
with prothorax (including apex and base) and elytra (base, sides, 
and apex) margined with testaceous, the pale color expanded inward 
on elytra before subapical curve, and dark color reaching margin of 
elytra at the curve and extending forward along actual margin ; 
moderately shining, faintly iridescent, microsculpture absent or faint 
on head, apparently fine and strongly transverse on pronotum and 
elytra. Head .70 and .73 width prothorax (in cf 9 measured) ; eyes 
smaller than in preceding species, partly enclosed by genae, forming 
obtuse angles with neck; antennae with middle segments slightly 
longer than wide; frontal sulci impressed, diverging posteriorly, almost 
reaching anterior supraocular setae. Prothorax rounded-transverse, 
with basal angles very obtuse ; width/length 1.5 1 and 1.50; base/apex
