joint as long as the rest together; body beneath with a pale-greyish 

 pile. Length 10 lines. 



The crescent-shaped scries of short crests on the prothorax will 

 readily distinguish this species ; the hairs on the elytra appear to 

 be very deciduous, and are generally rubbed off the more prominent 

 portions.

Symphyletes pubiventris. 



S. subcyhndricus, pube cinerascente Mvaque variiis ; elytrorum lateribus 

 maciilis duabus albis; maris abdominis segmento secundo ampliato, 

 densissime hirsute. 



Hah. Australia (Kangaroo Island^. 



Subcylindrical, black, covered with a short, very pale ashy pile, varied 

 with light fulvous, and spotted with coarse black pimctures; head 

 rather nan-ow, the vertex very convex ; antennae nearly equal in both 

 sexes, not so long as the body, dark brown, not spotted, and very 

 slightly ciliated beneath ; prothorax nearly equal in length and breadth, 

 the anterior margin scarcely naiTOwer than the posterior, the side a little 

 roimded, although uregularly, the disk with the two usual shallow 

 transverse depressions; scutellum subtriangular, roimded posteriorly; 

 elytra subparallel, the apex entire, several black shining granules 

 arranged in in-egular rows, and extending to near the apex, two white 

 in'egxilar spots on each side partially margined with dark brown ; legs 

 and body beneath covered with a similar varied pile ; the second abdo- 

 minal segment in the male larger than in the female, and densely 

 covered with short erect hairs. Length 8 luies. 



A more cylindrical species than most others of this genus, in 

 general colour approaching S. fronticornis, Fab. ; but the two white 

 spots on the sides of the elytra will readily distinguish it. The 

 peculiar structure of the second abdominal segTuent is very rarely 

 met with among the Longicorns, and appears to be confined to the 

 males. There is nothing to distiaguish Si/mpliyletes from Rlujtipliora, 

 Serv., except that the latter has not the lateral tooth on the protho- 

 rax, which generally characterizes the former ; the last joint of the 

 antennaj, "apke repente curvato,'" which Newman gives as a character, 

 is only found in two or three species. How PentJiea, Lap., is to be 

 distinguished I don't know ; it is a stouter form, with shorter and 

 more robust legs, than either Symphyletes or Rhytiphom. My Penthea 

 conferta (Aru), from its toothed mesosternum and absence of an ten - 

 nary tubercles, must be excluded from the genus. Perhaps it should 

 be placed near Coptops, Serv. The spine on the anterior coxsc of the
