tip of abdomen with long and rather sparse hairs, rest of abdomen with (for the 

 genus) rather sparse clothing. 



Head oblong-ovate ; with large scattered punctures and a few minute ones ; 

 under-surface with a few scattered punctures. Labrum large, deeply notched 

 in middle, concealing most of mandibles when clenched. Eyes large, invisible 

 from below. Mandibles long and acute, with an acute tooth near middle 

 and two minute ones at base. Antennae thin, none of the joints transverse, first 

 as long as second and third combined, third very little longer than fourth. Sub- 

 apical joint of maxillary palpi large, the apical one small and briefly conical. 

 Prothorax distinctly longer than wide, widest near apex, thence obliquely 

 diminishing in width to near base, all angles rounded ofif ; with an irregular row 

 of large punctures on each side of middle, and some large ones on sides, a few 

 minute punctures scattered about. Elytra small, shorter than head, and much 

 shorter than prothorax, base rounded, sides slightly dilated posteriorly ; with 

 large and fairly dense punctures. Abdomen large, slightly dilated posteriorly, 

 sixth segment largest of all, under-surface of seventh deeply notched, anal styles 

 long; with numerous but not crowded punctures. Femora rather stout, four 

 basal joints of front tarsi rather strongly inflated. Length, 7.5-8.5 mm. 



$ . Differs in having the head somewhat smaller, abdomen not notched, 

 and front tarsi less strongly (although noticeably) inflated. 



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



The infuscated parts of the head and prothorax are almost circular, they 

 are very distinct on some specimens, but scarcely traceable on others ; from three 

 to five of the apical joints of antennae are flavous. The fairly wide front tarsi 

 and distinct fourth joint of maxillary palpi would seem to refer the species to 

 Hypero'inma, but the mandibles are armed, as in Suniopsis. It is allied to H. 

 pictipes, from which it differs in being paler, with the legs uniformly coloured 

 (there are five specimens of the present species before me, and two of pictipes). 

 I have not dissected out the mentum, but there appear to be two small globular 

 processes at its apex. 



Hyperomma inquilinum, n. sp. 



6 • Pale castaneous ; elytra and most of abdomen infuscated ; mouth parts,, 

 two basal joints of antennae (the others missing), palpi, and legs flavous. 

 Upper-surface with sparse hairs at sides, the abdomen moderately densely 

 clothed. 



Head oblong-ovate ; with fairly large scattered punctures, and some 

 minute ones ; under-surface shining and with scattered punctures. Labrum 

 deeply notched in middle. Mandibles long, thin, curved, and simple. Eyes 

 rather large, invisible from below. Subapical joint of maxillary palpi large and 

 stout, the apical one small and briefly conical. Prothorax distinctly longer than 

 wide, widest near apex, where the width is slightly more than that of head, sides 

 gently rounded and decreasing to base ; a row of large punctures on each side 

 of middle, and others on sides, minute ones scattered about. Elytra small, about 

 two-thirds the length of prothorax and decidedly narrower, base strongly rounded, 

 the sides moderately so ; each with four irregular rows of large punctures. 

 Abdomen about half the total length, sides feebly increasing in width to sixth 

 segment, which is the largest of all ; with fairly dense punctures, except at tips 

 of segments ; under-surface of seventh segment with an equilaterally triangular 

 notch at apex. Femora stout, front tarsi moderately wide. Length, 3.5 mm.
