tate. The prothorax bears two oblique confluent depressions which 

 extend from the sides in front to the base ; its surface is rather coarsely 

 and almost rugosely punctured. Scutellum sub-triangular. The elytra 

 are coarsely, rugosely, and closely punctured. 



Length, nearly 3 lines. 



OBS. This insect, of which I found one specimen only at Tairua, is 

 allied to but not congeneric with Tec/imessa, from which it differs in the 

 structure of the eyes, antennae, palpi, &c. 



Its chief structural characteristics are, as follow : 



Antenna, eleven-jointed, sub-filiform, inserted on the head in front of 

 the eyes ; basal joint sub-pyriform ; second very small and transverse ; 

 third shorter than fourth ; joints four to ten about equal ; eleventh sub- 

 fusiform. Last joint of maxillary palpi almost cultriform ; apex almost 

 obtuse. Eyes large, slightly convex, and a little excised in front. Pro- 

 thorax rather small, somewhat transverse, considerably rounded and 

 narrowed in front and behind ; posterior angles not prominent, sub- 

 acute ; apex truncate, base finely margined and nearly truncate. Elytra 

 elongate, wider than thorax, widest behind, slightly convex, apex 

 obtusely rounded, sub-truncate. Legs of normal length ; femora sub- 

 linear, yet a little incrassated ; tibia straight, with minute apical spurs ; 

 tarsi with the fourth and third (anterior pairs) joints small, but dilated 

 laterally, the apical as long as the basal joint. 



FAMILY CURCULIONIDES. 



The head prolonged into a rostrum, bearing at its extremity the 

 organs of the mouth ; the latter complete, except the labrum, which is 

 absent. Mentum lodged in a hollow of the under-chin, or borne by a 

 peduncle proceeding from it. Ligula concealed by the mentum or 

 uncovered. The maxilla generally with one lobe only. Palpi very 

 short, conical or sub- cylindrical ; the labial with three, the maxillary 

 with four joints. Mandibles short, of variable form. Antenna inserted 

 on the rostrum, consisting of eight or twelve joints, geniculated in the 

 majority, and nearly always terminating in a club. Eyes very variable. 

 The pronotum confounded with the flanks of the prothorax. Anterior 

 coxce contiguous or otherwise, having their cotyloid cavities closed 

 behind ; the others separated ; tarsi generally spongy underneath, sub- 

 pentamerous ; their third joint often bilobed. Abdomen composed of 

 five (rarely of six) segments, the third and fourth ordinarily shorter than 

 the others. 



Group BRACHYDERID^E. 



The antenna geniculated \ scape of variable length ; funiculus with 

 seven (rarely with six) joints ; the club of normal structure. Rostral 

 scrobes often linear and directed downwards.

 furnished on the inner side with bent, rigid hairs. Labial palpi very
