164 Transactiojis. 



Toura, gen. nov. 



Body fusiform-cylindric. Rostrum of nearly the same length, as thorax, 

 nearly twice as long as that of 903. much more slender, evidently arcuate ; 

 very slightly, just perceptibly, broader in front than behind ; a little dilated 

 medially underneath ; nearly as stout but quite parallel in the female. 

 Scrobes elongate. Scape somewhat curved, moderately incrassate apicallv, 

 inserted distmctly before the middle, but only reaching the front of the 

 eye. Funiculus rather elongate, 2nd joint nearly as long as the 1st, joints 

 3-5 somewhat laxly articulated. Club indistinctly annulate, moderate. 

 Eyes rotundate, moderately prominent. The smooth occiput marked oft" 

 in line with the back of the eyes. Thorax triangularly ovate, constricted 

 in front. Scutellum distinct. Elytra slightly biarcuate at the base and 

 rather broader than that of the thorax, subfusiform. Legs elongate and 

 rather slender ; tibiae only a little expanded towards the extremity ; 

 3rd joint of the tarsi expanded and moderately bilobed. 



Prosternum elongate, intercoxal suture strongly curved. Basal 2 ventral 

 segments as long as the metasternum. Rostrum bisulcate and tricarinate 

 underneath. 



The nearly similar rostrum of both sexes, its upper curvature and unusual 

 length, the antennal insertion, different scrobes, curved scape, slender legs, 

 expanded and lobate 3rd tarsal joint, and more approximated front coxae 

 are sufficient for generic separation of Wollaston's Pentarthrmn longirostre, 

 which I adopt as the type of Toura. In the female the antenna? are im- 

 planted before the middle, just the reverse of what is the case in Pentarthrum. 

 It bears some resemblance to PhJceophagosoma. 



Toura longirostre, Wollaston. 904. Man. N.Z. Coleopt., p. 508. (Plate XV. 



fig- 5.) ... 



Nitid, piceous or nigro-piceous. legs and antennae pitchy-red. 



Rostrum rather finely and closely punctate, the interocular sculpture 

 similar, the occiput smooth. Thorax rather abruptly contracted near the 

 apex, finely punctured there; disc convex, moderately coarsely punctured, 

 its sides moderately rounded. Elytra not perfectly parallel, slightly nar- 

 rowed backwards : punctate-striate, sutural stride deep, the suture and 

 interstices with fine serial punctures and slightly transversely rugose. 



Underside a little glossy, nigrescent, with some minute hairs, moderately 

 coarsely punctate. Basal ventral segment broadly depressed, the terminal 

 one with a large transverse oviform depression which is densely and minutely 

 sculptured.

Parua, Whangarei. Both sexes. 



T. fulva, Broun. 2188. Man. N.Z. Coleopt., p. 1243. 



Shining, fulvescent, club fuscous, tarsi yellowish. 



Smaller than 904. Rostrum very finely punctate. Thorax rather small, 

 narrower than the elytra, more cylindrical, their sides very slightly and 

 regularly rounded from the truncate base to the apical contraction, the 

 disc more finely but less closely punctured. Elytra subparallel before the 

 middle, gradually narrowed posteriorly, each slightly rounded at the base, 

 their striae and punctures finer.
