OF NEW ZEALAND. 1417 



Female. Colour darker. Antenna with the second joint nearly 

 as large as the first ; third and fourth small ; fifth larger than the 

 contiguous ones ; eighth and ninth transverse, the latter the larger ; 

 tenth twice as large as ninth, also transverse ; eleventh largest. 

 Underside simple, metasternum convex. 



Differs from B. conspicua in having smaller and less prominent 

 eyes, stouter legs, differently-formed antennae, &c. The abdominal 

 costae are distinctive. No. 1347 is also closely allied ; it has the 

 ninth and tenth antennal joints more transversal, and not exactly 

 of the same shape. 



Length, f ; breadth, nearly line. 



Eiccarton Bush, Christchurch. Five specimens were placed at 

 my disposal by Mr. Suter. This and Tyrus spinipes are the only 

 species of Pselaphidce as yet found in Canterbury east of the 

 mountains. 



232. B. platyarthra. Body nearly glabrous, shining, dark- 

 red, the legs, elytra, and antennae paler, tarsi and palpi fulvous. 



Head depressed between the antennal tubercles, the foveae of 

 the vertex small or indistinct. Thorax but little longer than broad, 

 widest at the middle, the sides behind flattened, but not obviously 

 foveate. Elytra large, slightly narrowed near the shoulders, with 

 fine sutural striae. Abdomen short, deflexed, with fine greyish 

 pubescence. 



Male. Antenna ten-jointed, the basal joint longer and thicker 

 than the second ; third longer than the small fourth joint ; fifth 

 rather longer than sixth ; seventh and eighth small, subquadrate ; 

 ninth very large, much prolonged outwardly, this external portion 

 not more than half the length of the other, on the inner face it is 

 deeply notched, and has also a cavity at that point, there is an 

 indistinct suture between the basal portion and the transversely- 

 enlarged part, showing that the almost complete anchylosis of the 

 ninth and tenth joints has taken place; tenth joint short, sub- 

 conical, one-half the width of the preceding one ; these large ter- 

 minal joints are asperate, and bear obvious yellow hairs. 



Anterior coxa 1 , distinctly spined ; metasternum slightly impressed ; 

 basal segment of the abdomen large, with two small tubercles, the 

 last segment simple, the others short. 



Distinguishable by the structure of the ninth joint of the 

 antennae. 



$ . Length, f ; breadth, f line. 



Tairua, two males ; Hunua Eange, one. The name B. clavata 

 having been used before, I now rename and redescribe the species 

 No. 232. 



236. B. munduluS. Shining rufescent, the head and thorax 

 usually darker than the elytra, tarsi yellow ; nearly nude. 



Head with indistinct interocular foveae. Thorax not much longer 

 than broad, widest just before the middle. Elytra large, slightly 

 narrowed near the base, the sutural striae distinct but fine. Hind-
