])unctured, even on the legs and the antennae ; the tibiae of all the 

 legs are considerably bent at their origin. 



This was obtained on the voyage of H.M.S. Sulphur, and is more 

 likely to be from the west coast of America than from China. 



5. Anisocerus onca. 



A. pallide ochraceus Tufescenti tinctus ; capite thoraceque nigra 

 maculatis et fasciatis ; elytris singulis 17—18 maculis nigris ; 

 corpore subtus nigra fasciato ; antennis articulo tertio opice 

 nigro-fasciculato ; tihiis tarsisque pallidis, tihiis apice nigris. 



6. Anisocerus capucinus. 



A. ater, genis miniaceo vittatis ; scutello nigra ; elytris miniaceis, 

 fasciis tribus transversis et macula ante apicem nigris, sutura 

 nigra. 



7. Anisocerus dulcissimus. 



A. ater, genis miniaceo vittatis ; elytris sulphureis seu albida- 

 Jlavescentibus ; fascia basali angusta et scutello miniaceis, 

 fascia lata ante medium obscure miniacea ; marginibus apicali 

 et laterali miniaceis ; punctis quatuor nigris in parte postica 

 elytrorum. 

 These three fine species of the peculiarly Brazilian genus Aniso- 

 cerus are described in the second part of the Museum Catalogue of 

 Longicorn Beetles, pp. 405, 406. It is just possible that the two 

 last so-called species may eventually be found to be one. We have 

 two specimens of the last which differ from each other in coloration, 

 and probably connecting varieties may yet be sent to our collections 

 from the banks of the Amazon. The A. capucinus was first ob- 

 tained at Para by J. P. George Smith, Esq. of Liverpool ; the A. 

 dulcissimus was found on the Tapayos, a tributary of the Amazon, 

 by Mr. Bates, who also sent the A. Onca from Ega, a locality on the 

 same great river, which has proved to be very prolific in insect life. 



8. Ph^dinus xanthomelas, n. s. 



P. niger ; abdomine subtus pallida, elytris sulphureis, apice macu- 

 laque ante medium nigris; femaribus subtus ultra medium 

 cilia tis.

Head rather wide, black ; eyes ferruginous ; a yellow mark on the 

 clypeus, with many scattered punctures. Antennae with the two basal 

 joints shining, the others dull ; joints from the third to the tenth 

 dilated triangularly at the tip on the inner edge ; terminal joint ob- 

 long, sides parallel, tip pointed. Thorax densely punctured and 

 hairy, a smooth spear-shaped space on the back in the middle, pointed
