PAEDERIDAE. 483 



Antennae distinctly pubescent, short ; basal joint not as long as follow- 

 ing two combined. Anterior tarsi with the basal three joints as long as 

 broad, not expanded, penultimate smaller, the terminal nearly as long as 

 all the others. Eyes moderate, nearly flat, with distinct facets. Mandibles 

 elongate, bidenticulate at the base, the inner, prominent tooth of each 

 subacute and placed between the middle and base. 



The shorter head differentiates this species from all but H. dispersum 

 (2454) ; the mandibles of the latter, however, though bidenticulate at the 

 base, are without the common elongate inner teeth. 



?. Length, 6| mm. ; breadth, I mm. 



Mount Alfred, near Lake Wakatipu ; 4th February, 1914. The single 

 female before me is another of Mr. T. Hall's discoveries ; elevation, 4,200 ft. 



3988. Hyperomma discrepans sp. nov. 



Subparallel, shining ; hind-body subaeneo-piceous, the head and thorax 

 more nigrescent, mandibles rufous ; labrum, palpi, antennae, and tarsi 

 rufo-testaceous ; legs castaneous ; pubescence ashy and depressed on the 

 hind-body, very scanty and suberect elsewhere. 



Head slightly longer than broad, its sides nearly straight, curvedly 

 narrowed behind ; with four interantennal punctures, the inner pair small, 

 there is a pair close to each eye and another nearer the middle more distant 

 from each other, behind the eyes and across the base there are several dis- 

 tinct punctures, there are also minute ones on the middle. Thorax not 

 broader than the head, a third longer, with straight sides and moderately 

 rounded angles ; along either side of the middle there is a series of about 

 thirteen definite punctures, those near the sides are less numerous and 

 irregular, between the rows there are many minute punctures. Scutellum 

 smooth. Elytra truncate and a« broad behind as the thorax, with curvedly 

 narrowed shoulders, they are distinctly but only subseriately punctate. 

 Hind-body half of the entire length, irregularly but distinctly punctured, 

 basal segment half as long as the transversely quadrate following four, 

 sixth rather longer ; seventh narrower, membranous, pale, and rounded 

 at the extremity, with a triangular but small impression there, this in some 

 aspects seems to be an incision ; the corresponding ventral segment has 

 a pair of pale cylindrical appendages which, though visible from above, 

 are much smaller than the coarsely setose styles. 



Mandibles, eyes, and palpi similar to those of H. picipenne ; basal joint 

 of antennae almost as long as the next two combined. Tibiae irregularly 

 and fijQely spinulose, the intermediate pair most distinctly. Anterior tarsi 

 setigerous, their basal four joints moderately dilated, each transversal. 



This, like H. lohatum, is another species in which the seventh dorsal 

 segment, and the corresponding ventral one, together, form the principal 

 distinguishing feature. 



S. Length, 8^ mm. ; breadth, 1^ mm.

Elongate, slightly convex ; head, thorax, and elytra shining chestnut- 

 red and nearly glabrous ; legs much paler, palpi, antennae, and tarsi
