type. The pale parts of the abdomen are the seventh segment, apical half and 

 sides of the sixth, and sides and tips of the others. 



A male, from Victoria (Blackburn's collection), evidently belongs to the 

 species, but dififers from the type in being larger, 4.75 mm., with less of the 

 sixth and seventh segments of abdomen pale, and more of the others; the 

 antennae are perfect, their median joints are slightly infuscated and apical ones 

 flavous, the fourth to tenth are each about as long as wide or very slightly 

 transverse, and the eleventh is longer. 



Hyperomma microps, n. sp. 



9 ■ Pale castaneous ; antennae, palpi, and legs still paler. Sides Avith a 

 few straggling hairs, abdomen rather sparsely clothed. 



Head subovate, with a large neck ; with fairly dense and large punctures ; 

 under-surface with a few scattered ones. Eyes minute and lateral. Mandibles 

 long, with a strong compound tooth, about one-third from base but normally 

 concealed. Antennae short, fourth to ninth joints slightly transverse, tenth about 

 as long as wide, eleventh slightly longer. Maxillary palpi with subapical' joint 

 large and swollen, apical one small and briefly conical. Prothorax much longer 

 than wide, apex scarcely wider than base and narrower than head, all angles 

 rounded off; with an irregular row of rather large pimctures on each side of 

 middle, and two still more irregular rows on each side, minute punctures scat- 

 tered about. Elytra very small, much shorter than prothorax, and at apex about 

 as wide, but feebly decreasing in width to base; with rather sparse and rather 

 large punctures, a few forming an irregular row on each side of suture. Abdomen 

 gently increasing in width posteriorly, sixth segment largest of all and distinctly 

 wider than head ; with fairly numerous punctures. Legs rather short, front 

 tarsi simple. Length, 4 mm. 



Hah. — Tasmania: Waratah, in moss (A. M. Lea). Unique. 



An anomalous species, for which probably a new genus should have been 

 proposed. The minute eyes, strictly lateral and consequently visible both from 

 above and below, are distinctive from all known species of Hyperomma and 

 Suniopsis, and the antennae with most of the joints transverse are also aberrant; 

 the front tarsi are simple as in Suniopsis, but the apical joint of the maxillary 

 palpi is distinct ; the mandibles are dentate, but they vary in Hyperomma. It 

 should possibly have been referred to Scimhaliiim, but as I know no apterous 

 species of that genus, and as in most generic details it agrees with Hyperomma, 

 it has been referred to the latter. In size it is only larger than H. inquilinum. 



Macrodicax, n. gen. 



Head large, with a wide neck. Eyes small, latero-frontal. Labrum trans- 

 verse, sides pointed. Mandibles long and powerful, strongly tridentate. Mentum 

 with two globular processes in front; labial palpi small and thin. Maxillary 

 palpi with subapical joint large, shorter than preceding joint, and about twice 

 the length of the apical one, which is conical. Antennae thin but not very long. 

 Prothorax large, somewhat dilated in front. Scutellum strongly transverse. 

 Elytra small. Abdomen rather short and wide, five segments strongly margined, 

 anal styles moderately long. Femora rather stout, edentate ; hind tibiae rather 

 long, the others shorter; front tarsi with four basal joints dilated to form a 

 conspicuous pad, the fifth rather long and thin; basal joint of each of the other 

 tarsi distinctly longer than the second, the others evenly decreasing in length to 

 fourth, fifth as on front tarsi. Body apterous. 



A remarkable genus with two ball-like objects in the mouth, as in 

 Hvperomma (they are visible from directly in front and very distinct from
