Ctexoplectron sericeum, n.sp. 



Blackish ; under surface and appendages of a dingy reddish- 

 castaneous. Densely clothed with extremely short, silken pubes- 

 cence. 



Head rather convex. Eyes large, suhreniforni. Antennae 

 moderately long and thin, second joint about half the length of 

 third, the latter slightly shorter than first. Prothorax about 

 as long as wide, base lightly bisinuate and near base with three 

 shallow round depressions, hind angles obtuse, front ones 

 strongly rounded off; marginal carina on each side acute from 

 base to slightly beyond the middle, but vanishing before the 

 apical third. Elytra long, thin, and parallel-sided to beyond 

 the middle, striatum fairly well-defined. Four hind tibiae 

 strongly serrated on the upper surface, spurs to hind pair very 

 unequal, the longer about twice the length of the other, and 

 about half the leng-th of the following joint. Length, 8 mm. 



Hub. — Tasmania: Ulverstone, unique (A. M. Lea). 



With the general appearance of C. agile, but elytra more 

 strongly striated, the suture not serrated posteriorly, and the 

 pronotum with the median line absent except for a vague basal 

 depression. The punctures are dense and everywhere very 

 minute, so that they are scarcely to be seen under a Coddington 

 lens. 



CERAMBYCIDAE. 



Cremys diophthalmus, Pasc. 

 A specimen from New South Wales possibly represents a 

 variety of this species; it differs from the description in hav- 

 ing the derm of the prothorax entirely black, and the elytra 

 black except for a narrow line on each elytron; this line com- 

 mences near the side about the middle, is directed obliquely to- 

 wards the suture, and is then deflected upwards parallel with 

 the suture half-way to the base; the femora and tibiae are dark. 

 In the original description the elytra are noted as having only 

 the apical half black, and with a pale line apparently as on my 

 specimen ; the prothorax was also noted as having two black 

 spots. Later, in diagnosing the genus, Pascoe again commented 

 upon two black prothoracic spots. Lacordaire, however, shows* 

 the elytra as having a postmedian fascia and the suture pale
