cxxviii Mr. E. Newman's Descriptions 



raised longitudinal lines are much less pinky and well denned in consequence of a 

 yellow colour, the spots upon them are much larger and scarcer than on the other 

 parts of the body. The shorter tentacula are of an uniform, dirty, transparent white ; 

 the longer the same, but having, in addition, blotches of pink and puce : in the in- 

 terior of each are visible, small, oval, cream-coloured bodies: oral disk pellucid, with 

 the appearance of chalk having been sprinkled over it. I have satisfied myself by 

 examination that this is not the young of any of our described species. The descrip- 

 tion is very particular, but I thought, claiming it as new, I could not be too much so. 

 Hab. — I found this Actinia attached to the rocks under Sandsfoot Castle, in Wey- 

 mouth Bay, at extreme low-water mark, spring tides.

 By Edward Newman. 



Family — Cerambycixle. 



Genus — Pempsamacra, Newman. 



Pempsamacra pygm^ea. 



Supra aheneo-fusca, subtus argenteo-albida ; antennarum articulo 5to, elytri utriusque 

 macula subrotundd submediand fiavescentibus. (Corp. long. '3 unc. Elytrorum 

 lat. max. "09 unc.) 



The prevalent and very uniform colour of the upper surface of this little longicom 

 is a brassy brown, that of the under surface a silvery but not brilliant white ; in the 

 antennas, the fifth joint, the comparatively great length of which has been employed 

 as a distinguishing character of the genus, is yellow except at the apex, which together 

 with the remainder of the antenna is brassy brown ; on each elytron, at half its length 

 and near its costal margin is a nearly round yellowish spot. 



Hab. — A single specimen taken at Wonboyn River, near Cape Howe on the east 

 coast of Australia, was taken by Mr. Mossman, and consigned to Mr. S. Stevens. 



Cerambyx pullus. 



Niger, concolor, lanugine brevissimd pallidiori undique obsita : prothoracis tuberes 5 : 

 1 utrinque lateralis 3 dorsalibus in triangulo dispositis. (Corp. long. *75 unc. 

 Elytrorum lat. max. '2 unc.) 



Black and perfectly concolorous, except that a very short, paler down clothes the 

 upper surface of the insect, while the lower surface is glabrous and almost naked : the 

 antenna? are 1 l-jointed, rather slender, and not half the length of the body ; the pro- 

 thorax is short, scarcely longer than the head ; about the middle of each side it 

 has a strong tubercle, and dorsally it has three tubercles arranged in a triangle, two
