Tairua (Capt. Broun). 



Like Tychius schneideri, but, in consequence of its more or less 

 exposed pygidium, I refer it to Sibinia. 



Group— CRYPTORHYNCHID^. 



Rostrum variable, Antennal funiculus with seven, rarely with six 

 joints. Eyes usually very large, and to some extent covered during the 

 retraction of the rostrum. Prothorax often prominent in the middle of 

 its front margin, or sinuated towards each side ; generally with ocular 

 lobes; prosternum canaliculate. The scutclluni distinct, or not. Elytra 

 nearly always covering the pygidium. Front coxc?. prominent ; tibicz 

 spurred or mucronated at the extremity ; claws of the tarsi simple. 

 The three intermediate segments of the abdomen of variable relative 

 length. 



Body of variable form.

Forehead vertical, plane ; rostrum hardly longer than the head, 

 parallel, impressed at the end, with somewhat prominent angles ; its 

 scrobes profound, oblique, reaching the lower margin of the eyes. 

 Antenncz short, robust, scape strongly clavate at the extremity, attaining 

 the eyes ; first joint of i\\Q funiculus stout, obconical, second very much 

 shorter and not so thick, joints three to seven transversal, compact ; 

 club oblong-oval, scarcely articulate, obtuse at the end. Eyes rather 

 convex, oblique. Prothorax transversal, convex, gradually narrowed, 

 then almost tubular in front, sinuated at the middle of its apex, bisinu- 

 ated at the base ; prosternum widely and somewhat deeply canaliculate, 

 terminated by a cavity for the reception of the tip of the beak. Scutel- 

 lum elongate-triangular. Elytra convex, oval, not wider than the pro- 

 thorax, and, conjointly, hollowed at their base, shoulders obsolete. Legs 

 short, robust, compressed ; femora sublinear, the anterior inflated and 

 dentate below ; front tibia strongly, the others more briefly produced to 

 a point, mucronate, the anterior having the inner apical angle dentiform, 

 the intermediate furnished externally with a stout tooth near the middle ; 

 tarsi rather long, first and second joints narrow, the former nodose at 

 the extremity, both imperfectly spongy below, third moderately wide, 

 fourth rather long, also its claws. Second abdominal segment longer 

 than third and fourth united, separated from the first by a strongly
