llie'aiitcrior angles terminate in a elioi't spine, and the long lateral 

 spine is exactly in the middle, the surface being covered a\ illi coarse 

 rugged sculpture, and with two irregular longitudinal ridges. 



The male of this fine insect is in the possession of Dr. F. Baden of 

 Altona, to whom my collection is indebted for the female specimen. 



Lamiidje, sub-fam. Anisocerince. 

 Phacellocera plagiata, n. sp. 



P. plumicorni roiustior ; fusca,, vitta lata mediana a vertice usque prope ely- 

 trorum apicem {ibique dilalata) ducta, ochraceo-cinerea ; antennis minus elongatis, 

 nigro-piceis, articulo 3'o apice nodosa. Long. 6i lin. 



Of rather broader and more robust form than either P. plumi- 

 cornis or Batesii, and totally different in colour, the upper surface 

 being dark brown, with a broad central ochreous-ashy vitta extending 

 from the top of the forehead, along the cro^vvn, thorax, and sutural 

 region of the elytra, nearly to the apex, just before which it is widely 

 dilated, thus leaving only a narrow apical border of the dark ground 

 colour. The sculpture of the elytra is very different from that of the 

 other species, the brown portion (especially towards the base) being 

 thickly punctured, with the anterior edges of the punctures raised iu 

 granula?. The body beneath scantily pubescent. Antenna? piceous ; 

 apex of third joint enlarged and hairy, fourth and following simple. 

 Tarsi testaceous tawny. The pro- and meso-sterna are narrow and 

 simple.

ClIALASTI>-US RECTICORNIS, 11. Sp. 



C. Egaensi (White) simillimus, at antennis ariiculis 5 — 7 c? red is ; fuscus, 

 ochraceo-irrorattis, lineaque dorsali thoracis ochracea ; elylris maculis majoribus 

 iionnuUisfulvis,fasciaque obliqua ante apicem ochracea, an/ ire late nigro-marginata. 



Long. 6 — 7 tin. $ . 



Much resembling O. Egaensis, but distinguished by the antennal 

 joints being quite straight in the ^, instead of the 5th to 7th being 

 curved and produced interiorly at their apex ; these joints also arc 

 considerably longer than iu C. Egaensis. In other points there are 

 several minor differences. The elytra are much more triangular, and 

 the basal crests much more elevated. The posterior ochreous fascia 

 is sub-interrupted near the suture (as in Egaensis), but prcceiled by 

 a much broader black fascia, and there is a conspicuous oblong black 

 spot on the disc of each, near the suture.
