Zoology. 
In habit and colour the only representative of this genus is like the 
Chilian Phymatioderus bizonatus ; but its characters ally it with Grammico- 
sum and Hesperophanes, from both of which it differs in the prothorax and 
antenne. 
Xuthodes punctipennis, 
X. eapite prothoraceque fulvis, opacis; elytris nitide flavescentibus, 
nigro-punctatis, punetis apicem versus minutis, pone medium fascia 
angusta fusca ornatis; antennis, pedibus abdomineque luteis; pro- 
thorace impunctato, disco 5-tuberculato. Long. 73 lin. 
Hab.: Pitt Island. 
Xyloteles costatus. 
X. elongatus, fusco-metallieus, antennis pedibusque castaneis sub- 
tilissime tomentosis; ilis artieulis basi plerumque pallidioribus ; 
capite prothoraceque lvigatis, hoc in medio tenuiter cor- 
rugato; scutello semicireulari, griseo-pubescenti ; elytris ob- 
longo-obovatis, apicibus rotundatis, singulis fortiter quinquecosta- 
tis, costis duabus exterioribus basi conjunctis, interstitiis sparsim 
impresso-punetatis; corpore infra subtiliter punctulato ; abdomine 
segmentis quatuor basalibus utrinque macula grisea pilosa notatis. 
Long. 71-9 lin. 
Hab.: Pitt Island. 
What, from its narrower abdomen, I take to be the male, has shorter 
elytra less drawn out at the apex than the female ; the antenne are about 
. the same length—a little shorter than the body in both. This fine species, 
which at first sight might be taken to be generically distinct trom JXyloteles, 
was, like the last, found by Mr. Travers in Pitt Island, one of the Chatham 
group.
