482 COLEOPTERA. 



Head, exclusive of mandibles, rather longer than broad, its sides straight, 

 posterior angles curvedly narrowed ; there are two pairs of punctures on 

 the forehead, the inner much smaller than those near the antennae, it is 

 smooth along the middle, but there are some coarse punctures near the 

 sides. Thorax a third longer than broad, with straight sides and rounded 

 angles ; with a nearly regular series of about thirteen })unctures along each 

 side of the middle, which has several minute indistinct punctures, lateral 

 punctation irregularly biseriate. Scutellum smooth. Elytra small, almost 

 as broad as thorax, a third shorter, their shoulders curvedly narrowed, 

 apices truncate ; each elytron has three somewhat irregular series of punc- 

 tures, about six m each. Hind-body nearly half of the whole length, 

 irregularly but not deeply punctate ; basal segment very short, the follow- 

 ing four subequal, nearly quadrate, sixth slightly longer ; seventh as long 

 but narrower, with a subtriangular incision extending to its base, the 

 extremity of each side is rounded and appears lobate ; the supplementary 

 or eighth segment occupies the incision and is prolonged almost as far as 

 the terminal styles ; the corresponding ventral segments are similar, their 

 predecessor is smooth and sUghtly impressed along the middle. 



Antennae shorter than head and thorax. Mandibles elongate, each 

 bidenticulate at the base and with an inner, acute, prominent tooth behind 

 the middle. Labrum short, with a deep central notch. Labial palpi very 

 slender. Eyes moderate, not large, nearly flat, indistinctly facetted. 

 Anterior tarsi setigerous, their basal four joints distinctly dilated, the inter- 

 mediate ones rather larger than the basal or fourth, fifth short and slender ; 

 posterior tarsi elongate, their second and third joints, together, slightly 

 longer than first. 



More slender than 2708, H. sanguineum (Ann. Mag. Nat. Hist., ser. 6, 

 vol. xiv, p. 425), the head smooth in the middle, the inner teeth of the 

 mandibles not truncate at the extremity, the anterior tarsi similar to those 

 of other species, but the bilobate seventh dorsal segment is utterly unlike 

 that of any New Zealand member of the genus.

Glenhope. A solitarv male discovered by Mr. T. Hall on the 3rd March, 

 1915. 



3987. Hyperomma picipenne sp. nov. 



Elongate, nitid, fusco-rufous, elytra piceous. mandibles ruifescent, the 

 palpi, legs, and basal two joints of antennae fusco-testaceous, remaining 

 articulations more infuscate ; pubescence ashy, becoming thicker towards 

 the end of the hind-body, scanty but erect on the head and thorax. 



Head, excluding the mandibles, subquadrate, with rounded posterior 

 angles, its sides nearly straight ; there are four punctures between the 

 antennae, the inner pair the smaller, three distinct ones near each eye, and 

 a few others near the sides and base. Thorax a third longer than broad, 

 as much longer than the head, its sides straight, basal angles curvedly 

 narrowed, the anterior less so ; disc smooth along the middle, with a row 

 of about a dozen punctures along each side of it, those near the sides 

 irregular. Scutellum smooth. Elytra as broad as thorax, fully a third 

 shorter, shoulders curvedly narrowed, apices truncate, distinctly but some- 

 what irregularly punctured. Hind-body half the whole length, distantly 

 and irregularly punctate, basal segment hardly at all exposed, 2-5 trans- 

 versely quadrate, sixth rather longer, seventh shorter and narrower, rounded 

 behind, simple underneath, terminal styles prolonged.
