OF NEW ZEALAND. 1149 



Group— PTINIDiE. 



Cyphanobium. 



Nov. gen. 



Body short, broad, and convex, like a convex Cyphon. Head 

 moderate, broad, greatly inflexed. Eijes large and prominent, with 

 a small triangular notch or impression in front. Palpi small, 

 terminal joint securiform. Antcnuce- 11-articulate ; basal joint large 

 and thick, excavated in front and along the external side ; second 

 moderately stout ; joints 3-8 small and slender ; ninth and tenth 

 elongate, each with a long bicurvate tooth or lobe directed inwards, 

 nearly twice as long as the joint itself, these lobes proceed from the 

 base and are curved in opposite directions ; eleventh longer than 

 tenth, considerably thicker, nearly straight on the outside but widely 

 emarginated inwardly so as to appear sublunate. Thorax as broad 

 as elytra at base, apex rounded medially but strongly sinuated 

 laterally, the base too sinuate, the side forming merely an acute 

 angle ; in front, and underneath, deeply hollowed for the reception 

 of the head. Scutcllum small. Eb/lra oblong. Le/js moderate, 

 capable of being packed like those of the Byrrhidse ; tarsi short, 

 basal joints largest, 2-4 very transverse. Front cox<e elongate ; 

 middle cox'ce small, widely separated, the space between them un- 

 impressed. 



Fem. Antenme smaller ; ninth joint strongly produced inwardly, 

 so that the tooth or lobe is larger than the joint ; tenth large, 

 triangular; eleventh oviform. 



The type of the genus (No. 626, p. 313) is a remarkable creature, 

 of which I now give a brief specific description : — 



626. C. illustris. Piceous, a little nitid, covered with greyish 

 hairs, legs piceo-rufous, tarsi rufo-testaceous, basal joint of antenuce 

 red, remaining joints infuscate or testaceous. The punctation rather 

 line, that of the elytra somewhat irregular, being close on some parts 

 but on others nearly absent, thus leaving ill-defined smooth spaces. 



Length, 1^ lines ; breadth, -| line. 



Tairua. One male and two females. 



Xenogonus. 



2038. X. obSCUrus, n-s. (SJiarj]; Trans. Roy. Dub. Soc, 1886, 

 p. 405.) ^abcylindricus, sat elongatus, ferrugiueo-brunneus, brevis- 

 sime pubescens, elytris ad latera vage fusco-plagiatis. 



Long., 3mm. 



Covered with a dense, excessively minute pubescence of a pallid 

 fuscous tint, not variegate, though a darker patch appears vaguely 

 defined on each wing-case ; this is probably due to some arrange- 

 ment of the pubescence, as the position and shape of the darker 

 patch vary according to the light and point of view. The antenna 

 and legs are ferruginous, the former largely developed, the fifth joint 

 being broad as well as long, its width at the apex being, in fact, but
