OF NEW ZEALAND. 583. 



Tritocosmia, the other two genera of the " groupe. " These he differen- 

 tiates by the one having a tuft of hairs on the third joint of the antennae, 

 which the other has not. At best this is a doubtful character ; one 

 objection to it is, that the tuft very often, apparently, belongs to the 

 insect only in its earlier life. 



1019. S. pallidus, Pascoe; Ann. Mag. Nat. Hist., Sept., 1875. 

 S. elongatus, fulvescens, vix nitidus, capite prothoraceque saturatioribus 

 illo in medio canaliculate ; rostra longitudine paulo latiore, planato- 

 marginato ; antennis leviter piloso-fimbriatis, articulo tertio quam sequen- 

 tibus multo breviore ; prothorace latitudine sesquilongiore, postice grada- 

 tim latiore, pone apicem parum incurvato, supra lineis duabus pilosis 

 notato ; scutello subrotundato ; elytris prothorace quintuple longioribus, 

 supra planatis, singulis costulis duabus longitudinalibus instructis ; infra 

 pedibusque pube tenuissime indutis. 



Long., 7 lin. 



NOTE. Capt. Hutton found this species in the Waikato district, 

 and I found it at Tairua and Whangarei Harbour, but only some six 

 individuals. 



Drotus. 



Sharp ; Ent. Mon. Mag., Feb., 1877. 

 ( Cerambyddce, ex aff. Calliprasonis.) 



Head obliquely declivous in front, and produced into a broad pro- 

 cess, which has an elongate impression on each side in front of the 

 eyes ; eyes distinctly (but still only a little) emarginate, (less than in 

 Stenopotes but more than in Calliprason sinclairi) ; antennce with the 

 basal joint very elongate, and swollen towards the extremity; third 

 joint elongate ; thorax very uneven, constricted in the middle and again 

 at the base ; elytra slender, elongate, depressed ; legs very elongate, 

 slender ; femora not abruptly broader towards the apex. General form 

 very elongate and slender, especially posteriorly. 



The allies of this species are almost certainly Calliprason sinclairi 

 (unknown to Lacordaire) and Stenopotes pallidus ; from the former it 

 differs by the elongate and obliquely declivous front of the head, and 

 by the peculiar form of the thorax ; the antennae and legs of the two 

 being rather similar. The insect apparently agrees with Stenopotes pal- 

 lidus in the form of the head, but departs from it in the form of the 

 thorax and antennae. 



Lacordaire's groups of the allies are evidently artificial, but the pre- 

 sent insect would doubtless be placed by him in one of the first three 

 " groupes " of his Section B. Cerambyddes. 



1020. D. elegans, Sharp / Ent. Mon. Mag., Feb., 1877. Elon- 

 gatus, perangustus, minus convexus, fusco-rufus, capite thoraceque 

 obscurioribus, parcius griseo-pubescens, prothorace inaequali, bicon- 

 stricto, elytris sutura, lineisque duabus pubescentia pallida.
