580. DR. R. C. L. PERKINS ON THE 
obscure in the male, but is well developed in the other sex. Size 
of infernalis. 
Hab. North Queensland (Dodd), 1 2. 
5. PARALASTOR FRATERNUS Sauss. 
The male has the clypeus (at least for the most part), the frontal 
spot, and the front of the scape of the antenne orange or 
yellowish orange. The tegule are for the most part very minutely 
punctured and clothed with very short hairs or tomentum. 
Hab. The single male in the Oxford Museum is from New 
South Wales, the female type in the British Museum has no 
special locality assigned to it. 
6. PARALASTOR CONSPICUUS, Sp. N. 
3. Niger; clypeus, macula elongata frontalis huie adjuncta, 
articulus antennarum primus antice, maculeque 2 pronotales 
pallide flava, aut albido-flavescentia. Abdominis segmentum 
secundum fascia lata pallida basali, postice profunde triangulariter 
emarginata, et antice plus minus nigro-emarginata, ornatum, 
Clypeus profundissime emarginatus. Frons capitis ante ocellum 
anteriorem grosse punctata, punctis inter se distinctis. Anguli 
pronotales prominuli. Mesonotum sat grosse et distincte punc- 
tatum, exemplorum recentium dense nigro-tomentosum, pilisque 
erectis breviorilbus subpallidis vestitum. Scutellum tuberculo 
prominente munitum, propodeo antice grosse punctato. Tegule 
dense et minutissime ex parte majore punctate, punctis magnis 
nonnullis presentibus. Abdominis segmentum primum fortiter 
crebre punctatum, punctis sepe sub tomento denso abditis ; 
segmentum 2 ventrale post suleum valde fortiter elevatum, 
elevatione summa prominente; segmentum 7 ventrale_pilis 
erectis minus brevibus vestitum. Antennarum articuli 3 ultimi 
minimi., Al, costali parte excepta, hyaline. Long. 11-12 mm. 
Hab. North Queensland, Cairns district (Dodd). Vive 
examples. 
The sculpture of the tegule, as in fraternus, is quite different 
from that of P. imfernalis and its allies, the coarse punctures 
being altogether confined to their inner half (or almost so), the 
outer part bearing the very fine puncturation. 
7. PARALASTOR DUBIOSUS, sp. n. 
3. Hardly differs from P. conspicua in structure, and is pro- 
bably only a race of that species. The second abdominal segment 
is entirely pale, or has a more or less extensive median longitudinal 
dark marking, The silvery tomentum, that fills the ocular sinus 
and extends down over the deflexed sides of the clypeus, is more 
dense and conspicuous and the sculpture of the latter beneath it is 
somewhat changed in accordance. 
This form varies much in detail of colouring, as shown partly 
in the table of species above. In one example the pronotal spots
