Procirrus antiquus, n. sp. 



d • Opaque-black ; antennae, palpi, mandibles, and legs more or less red- 

 dish. Densely clothed with very short ashen pubescence. Length, 7.5 mm. 



Hab. — North-western Australia: Derby (W. D. Dodd). Type (unique), 



I. 12657. 



The dingy pubescence on the opaque derm give the whole insect a dingy, 

 rusty appearance; the darker parts of the abdomen (except the tip) are entirely 

 black, but the softer parts cause the tip of each segment to appear reddish. 

 Structurally it is very close to the preceding species, but differs in being much 

 smaller, black, the punctures on the head smaller and denser, and in consequence 

 less sharply defined, the ridge on the prothorax shorter and less conspicuous, 

 the notch on the abdomen much wider, and the slit on each side of the sixth 

 segment very faint. From some directions the elytra and most of the prothorax 

 appear multi-granulate. 



In forcing out the mandibles they were unfortunately injured, but the parts 

 that are visible are as on the preceding species. 



Procirrus ferrugineus, n. sp. 



? . Of a dingy rusty reddish-brown ; mouth parts, antennae, palpi, elytra^ 

 and legs paler, head almost black. Densely clothed with short, ashen pubescence, 

 becoming longer on tips of abdominal segments. 



Head rather small, moderately convex, hind angles strongly rounded off, 

 with a short narrow neck ; with crowded and rather small punctures. Mandibles 

 long and acute, a strong tooth near the middle. Antennae rather short, first 

 joint as long as second and third combined, second almost as long as third and 

 fourth combined, fifth to ninth as long as wide, or feebly transverse, tenth 

 longer, eleventh still longer. Prothorax about twice as long as wade, widest at 

 apex, which is about the width of head, sides feebly diminishing in width 

 posteriorly, all angles gently rounded off, with a faint median ridge on basal half ; 

 punctures crowded and slightly larger than on head. Elytra about as long as pro- 

 thorax, and somewhat; wider, shoulders rounded, sides thence parallel to near apex; 

 with rather coarse crowded punctures. Abdomen more than half total length; 

 with dense asperate punctures, becoming crowded at the base of each segment; 

 sides immarginate. Legs not very long; front tarsi with four basal joints 

 strongly dilated ; middle tarsi scarcely as long as the front ones, the basal 

 joint as long as the rest combined; hind tarsi slightly longer than the middle 

 ones, the basal joint considerably longer than the others combined ; hind tibiae
