18 Mr. D. Sharp oti the 



should have almost preferred to use Mr. Wollaston's TarpMo- 

 miinetes had it not been objectionably polysyllabic. 



4. I'arphiomimcfes Laicsoni, Woll. This speciesmay also 

 be at present classed in the genus Ulonotus, though it is aber- 

 rant from the sides of the thorax being without notches. 



5. Tarphiomimus tndentatus, Woll. With this Ectomida 

 lacerata, Pasc, is specifically identical, as I judge both from 

 the descriptions and from information received from Mr. Pascoe. 



6. Bitoma visulari's, White, which is at present correctly 

 associated wnth the generic name given to it by White. 



I have included in the eighteen species I have described a 

 very interesting insect allied to AgJycyderes setifer, West. 

 Though AgJycyderes has not yet been referred to the Colydiidte, 

 it appears to me that this may at present be done with ad- 

 vantage. 



Thus the number of species of Colydiidas at present known 

 to me from New Zealand is twenty-four. This number, though 

 large, will undoubtedly be much increased (more than doubled 

 I have no doubt, and highly probably even quadrupled) ; and 

 it is pretty certain that, like the Atlantic islands. New Zealand 

 will prove to be very rich in species closely allied to TarpJiius ; 

 the genus Syncalus, indeed, here described, is especially close to 

 the European and Atlantic TarpMits. I anticipate that some 

 very interesting comparisons wnll be suggested w^ien the New- 

 Zealand forms of the family are better known, as I hope may 

 soon be the case. 



The Colydiidffi form one of the less specialized of the Coleo- 

 pterous families. Many species appear to feed on the woody 

 tissue of phanerogamic plants, others on dry cryptogamic 

 products, while others, again, are found amongst much-decayed 

 leaves and woody matter in dark woods. Other species, on 

 the contrary, prey on the larvae of wood-feeding Coleoptera ; 

 and these species are often slender, elongate, and subeylindric 

 in form, to enable them to penetrate the burrows formed by 

 their victims. It is probable that New-Zealand species will 

 be found of all these groups. 



Ulonotus Brouni, n. sp. 



U. oblongus, piceus, supra variegatus, ina^qualis (et in elytris tuber- 

 culatus), Bubtiis setulis brevissimis tenuissimisque adspersus ; pro- 

 thorace lateribus bis indentatis ; antennis, tibiis tarsisque rufo- 

 ferrugineis, clava, tibiisque in medio nigrescentibus. Long. corp. 

 4^ m. m. 

 This species is very closely allied to TarpMomimetes viri- 



dtpictus, Woll., but is larger, and has the indentations at the
