Coleoptera from New Zealand. 165 



visible strife ; along" the sides a few long slender setas occur ; 

 the broad pygidium is uncovered. 



AntenncB stout, they reach backwards to the shoulders, 

 pubescent ; second joint almost as long and stout as the first, 

 not quite glabrous, 3 to 10 moniliform, third not longer 

 than fourth, only about half the bulk of the second, eleventh 

 largest. Maxillary imlpi stout, not elongate, the penultimate 

 joint somewhat dilated on the inner side, so as to be sub- 

 securiform, the terminal short and indistinct. Legs elongate, 

 with fine setfB ; anterior tihice stout, much bent, and some- 

 what thickened near the extremity ; tarsi with small joints, 

 none expanded, claws slender. No eyes can be detected. 



This is congeneric with No. 1644 ; it is slightly larger, the 

 thorax is much less contracted beliind, and the humeral 

 margins are more distinct and explanate. Dr. Sharp's 

 Cillenum suhca^cum has a transverse thorax. It bears more 

 resemblance to the European Anillus ccecus than to the New 

 Zealand Cillena.

Riccarton Bush, Christchurch. One found by Mr. H. 

 Suter amongst leaves on the ground. May 1893. 



Group Pselaphidae. 

 Tyrogetus, gen. nov. 



Body elongate, narrowed anteriorly, slightly convex. 

 Head oval. Antennal tubercles prominent, almost connate, 

 they extend forwards as far, or nearly as far, as the muzzle. 

 Maxillary palpi elongate, nearly as long as the antennae, first 

 joint small, second curyate, very slender and stalk-like for 

 more than half its length, its apical portion clavate and ovi- 

 form ; third nearly as long as the preceding one, its clavate 

 portion nearly half the whole length, tlie basal part forms a 

 straight slender stem ; fourth about as long as tiie third, its 

 apical half more gradually and less clavate, this portion 

 appears to be cleft longitudinally, as in Pselaphus^ the basal 

 part is stalk-like. Antennm 11-articulate. Tarsi rather 

 short, basal joint small, second and third about equal; with 

 two small claws, these, however, are so closely applied to 

 each other as to appear like one. Eyes small, coarsely 

 facetted, situated at the middle of each side of the head. 



This is distinct from Tyrus. The hind body is more like 

 that of Pselaphus. Tychus has but one claw. The Austra- 

 lian genera Tyraphus, Gerallus, and Durhos appear, according 

 to their descriptions, to be very different in some important 

 points.
