I 82 COLEOPTERA 



pubescence is more conspicuous, and the margins are a little more 

 conspicuous. 



Tairua. I have received one individual from Captain Broun ; a 

 second was destroyed on the journey. 



FAMILY COLYDIIDES. 



Ligula horny. Maxilla bilobed. Palpi and Mandibles very short. 

 Antenna with eleven or ten, very rarely with eight joints, sometimes 

 gradually incrassated, generally terminating in a club. Anterior and 

 intermediate coxa globose, sunk in their cotyloid cavities ; the posterior 

 transversal, contiguous or not ; tarsi with four joints, simple ; so also 

 their claws. Abdomen composed of five segments ; the two last, or the 

 last only, mobile. 



Group SYNCHITID^E. 



Posterior coxa contiguous. Abdominal segments of equal size. 

 Last joint of \hzpalpi not aciculate. 



Tarphiomimus. 



Wollaston. 



This genus is closely allied to Ulonotus, from which it differs chiefly 

 in the structure of the tarsi, the two basal joints of which are stout, and, 

 conjointly, almost triangular in form, the third minute, and the apical 

 elongate, and longer than the other three taken together. The coxa are 

 nearly equidistant, the posterior being rather more widely separated 

 than the two front pairs. The tibia are flexuose, and externally com- 

 pressed and slightly dentate. The antenna are not so long as the head 

 and thorax, with a stout basal joint ; the second is about half as long as 

 the first, and not so stout ; the third is longer than those which follow, 

 sub-cylindrical, though more slender at the base than the apex ; fourth 

 shorter than third ; joints five to eight nearly equal ; club three-jointed 

 and rather large, the ninth and tenth joints transverse; eleventh rounded. 

 Eyes rounded, prominent, coarsely facetted. Head dilated laterally in 

 front of the eyes, so as to conceal the base of the first antennal joint, 

 Thorax cordate, disc considerably elevated, the sides widely dilated, 

 and deeply indented. Scutellum small. Elytra oblong, moderately 

 convex transversely, margins serrate. Epipleura not very broad. 



These characters will lead to the recognition of this form. I have 

 not seen Mr. Wollaston's description. 



324. T. indentatus, Wollaston. Oblong, variegated with testa- 

 ceous and fuscous scales and pubescence, antennae and tarsi infuscate- 

 red. The head bears numerous minute tubercles. Thorax with three 

 lateral lobes, the anterior the largest, and deeply indented in the middle, 

 it forms the acute, prominent, front angle; the second is situate near the
