Psyche 
[September 
ments c. 3 X long as wide ; palpi slender, last segments rather long ( in 
genus) but slender, subulate. Pro thorax strongly narrowed anteriorly, 
slightly so posteriorly; width/length 1.32 & 1.33; base/apex c. 1.58 & 
1.47; base/head 1.38 & 1.37; apex subtruncate, slightly lobed at mid- 
dle; base subtruncate, broadly and slightly lobed at middle; sides 
broadly arcuate through much of length, broadly but rather slightly 
sinuate posteriorly; posterior angles c. right, well defined, costate; 
lateral margins moderate anteriorly, slightly broader posteriorly, each 
with usual 2 setae about 2/5 from apex and near basal angle; anterior 
transverse impression of disc broad, not sharply defined ; middle line 
rather coarse and well impressed, coarser basally and reaching base; 
basal sulcus distinct but not foveate, interrupted at middle by longi- 
tudinal impression; baso/lateral areas broadly depressed. Elytra broad 
(E/P 1.59 & 1 .6 1 ) , somewhat rounded at sides, widest about middle; 
striae moderately impressed, slightly, irregularly punctulate; dorsal 
punctures lacking. Length 3. 2-3.6; width 1.3- 1.6 mm. 
Holotype cf (M. C. Z. Type No. 30332) and 19 paratypes all 
from Bellangry Forest, northwest of Wauchope, New South Wales, 
about 3000 ft. altitude, April 1958, taken by myself. Also one speci- 
men, not a type, from Barrington Tops, Mount Royal Range, about 
4000 ft., October 1957, also taken by myself. All specimens were 
taken among lumps of dirt and in loose soil in damp situations. The 
first one at Bellangry Forest was washed from dirt and leaf litter 
from the ground in wet forest. After finding it, I searched for addi- 
tional specimens without success until I started kicking the actual 
broken earth bank of a small brook into the water. Then the series 
here recorded was collected without much trouble. The Barrington 
Tops individual was taken among lumps of earth beside a seepage near 
the top of the road that led up from the Allyn River toward (but at 
that time not quite to) the plateau. 
This species was very Trechus-MYe in life. It is somewhat Trechus- 
like even under the microscope, although its technical characters 
(subulate palpi, elytral striation, etc.) leave no doubt that it is a 
Tacky s. It is evidently related to ectromioides , but differs as indicated 
in the key. The absence of dorsal elytral punctures in this and the 
following species is unexpected, but I have examined all specimens of 
both the present and following species at about 100X under fluores- 
cent illumination, which reduces surface reflection and makes minute 
details clear, and have not found any trace of dorsal punctures in any 
specimen.
