cxxx Mr. E. Newman's Descriptions 



white costal vitta, are sufficient to distinguish it immediately : I will, however, add a 

 more detailed description. Antennae pitchy-brown, the basal joint glabrous and 

 naked, all the rest fringed on one side with black hairs ; the basal portion of each 

 joint is also clothed with short gray down : head brown, but nearly covered in patches 

 with a short fulvous down : an impressed, epicranial, glabrous line is prolonged an- 

 teriorly almost to the clypeus : prothorax brown with impressed rings, which are filled 

 with short fulvous down, thus appearing as fulvous rings, but these are attenuated 

 and almost interrupted on the back : elytra brown, with numerous, slightly raised 

 black tubercles near the base, numerous fulvous downy markings all over the sutural 

 and dorsal regions, a slender, gray, sutural vitta extending from the middle to the apex, 

 and a costal white vitta extending from near the shoulder to the apex ; beneath the 

 humeral angle, which is prominent and highly glabrous, is a white downy spot, con- 

 nected with the costal vitta by an extremely attenuated marginal line : beneath, the 

 body is covered with short down ; that on the sides of the mesosternum is pure white ; 

 that on the abdominal segments is gray, sprinkled with small, round, glabrous spots, 

 the margins of each segment being fulvous : legs short, stout, and variegated with 

 downy markings of gray and fulvous. 



Hab. — New Holland : I have seen many specimens of this insect ; that described 

 is in the possession of Mr. S. Stevens, consigned to that gentleman by Mr. Wilson. 



Genus — Acanthocinus, Megerle. 



ACANTHOCINUS LINEOLA. 



Niger, punctus, maculis minutis lanuginosis irroratus ; prothoracis lineold laterali 

 longitudinali alba. (Corp. long. '55 unc. Elytrorum lat. max. '225 unc.) 



Antennae black, fringed beneath with black hairs : prothorax black, with a slender, 

 longitudinal, white line on each side above the lateral spine : elytra deeply punctured, 

 indistinctly ribbed : beneath clothed with whitish down. 



Hab. — Kangaroo Island : in my own collection. 



This form in Lamia is very numerous in individuals if not in species, throughout 

 New Holland : the present species somewhat resembles the annulicornis of Latreille, 

 described under the name of Acanthocinus marginicol, by Boisduval, ' Faune de 

 l'Oceanie,' p. 490, but from this very common species it differs in wanting the beau- 

 tiful annulations of the antennae, and in having the broad, gray, lateral vitta of the 

 prothorax replaced by a slender white line. 



Acanthocinus ? plumula. 



Antennce corpore paullb longiores, basi sat proximce, 10-articulata, articulo secundo 

 sesquialtero, quinto apice plumoso, nigra, maculis elytrorum nonnullis, incertis, 

 lanuginosis, canis. (Corp. long. '475 unc. Elytrorum lat. max. '2 unc.) 



Antennae rather longer than the body, somewhat approximate at the base, the head 

 being longitudinally grooved between them, 10-jointed; the first joint long and stout, 

 the second less than half the length of the first, rather stout and apparently divided 

 into two, but whether this division is apparent only or real, is a point on which, with-
