Broun. — Revision of the New Zealand Cossonidfe. 211 



rowed and declivous near the extremity ; rather coarsely striate-punctate, 

 the punctures regular and distinctly separated, quite striate behind ; the 

 suture and interstices with fine serial punctures, 3rd and 5th slightly elevated 

 throughout, the 2nd towards the extremity only. 2nd joint of the funiculus 

 longer than the 3rd. Penultimate joint of the tarsi distinctly broader than 

 the 2nd, not lobate. 



Underside shining, piceo-fuscous, minutely pubescent, rather coarsely 

 and irregularly punctate, mesosternura smooth in front, metasternum and 

 basal segment broadly impressed. 



When compared with A. sternaUs, its nearest ally, the cordiform elytra 

 are seen to be broader and regularly sculptured, the thorax is much less 

 narrowed in front, with more rugose and closer punctures, the rostrum is 

 subopaque instead of shining, and the vestiture is entirely different. 



Length, IJ lines ; breadth, nearly ^ line. 



Clevedon, Hunua Range. 



Pselactus, Broun. Man. N.Z. Coleopt., p. 972. 



Body robust, transversely convex, slightly nitid, sparsely but distinctly 

 setigerous. 



Rostrum about as long as the thorax, stout and moderately broad, 

 parallel ; female rather more slender and elongate, but not very narrow. 

 Head globose, rather short, curvedly narrowed anteriorly, a little depressed 

 towards the rostrum, which is about half the width of the occiput. Scrobes 

 directed obliquely downwards. Scape short, moderately curvate and 

 slender, thicker at the extremity, inserted medially, a little further back in 

 the female, it reaches the eye. Funiculus much longer than the scape, 

 basal joint stout, 2nd rather longer than 3rd, joints 3-7 submoniliform, 

 transverse, 7th larger than the preceding one. Club oblong-oval, densely 

 pubescent, indistinctly annulate. Eyes placed in front of the head, widely 

 distant, depressed, transverse, suboval, truncate in front. Thorax of nearly 

 equal length and breadth, its sides distinctly rounded, obsoletely constricted 

 in front, base truncate. Scutellum absent. Elytra oblong, evidently 

 broader than the thorax, the shoulders a little curvedly narrowed, their 

 sides slightly rounded, posterior declivity nearly vertical. Legs moderate, 

 tibial hooks strongly developed. Tarsi very long and slender, penultimate 

 joint slightly expanded and bilobed ; claws minute. 



Anterior coxse contiguous. Prosternum deeply incurved. Mesosternum 

 on an abruptly lower level than the metasternum, which is shorter than 

 the basal 2 ventral segments and somewhat angularly impressed behind, 

 2ncl segment rather shorter than the 1st, the suture sinuate. 



In some respects similar in structure to the Crotian Cotaster, but the 

 thickset body, depressed transverse eyes, the short slender somewhat 

 arciiate scape of the male (which, however, is longer and less curved in the 

 female), the short rounded thorax, abbreviated metasternum, contiguous 

 anterior coxae, and the absence of the scutellum, taken together, prevent 

 its location in the vicinity of the section in which Cotaster has been placed. 

 The front of the prosternum, too, is angularly depressed, but in front of 

 and beyond the coxte an elevated area comes in contact with them, whilst 

 a slight angular process, apparently cariniform in the middle, projects 

 behind them. The seta? are suberect, slender, and in unabraded specimens 

 rather thickly scattered over the elytra. It is an inhabitant of the sea- 

 shore.
