Longicornia of Australia and Tasmania. 177 
20. Sisyrium ? plagiatum, sp. n. 
Setis suberectis sparse obtectum; capite pronotoque infuscatis ; 
prothorace quam latiori distincte longiori, lateraliter in medio 
leviter tuberculato, supra sat dense punctato; elytris flavescentibus, 
fascia lata inter medium apicemque et plaga subquadrata utrinque 
ante medium fuscis, fortiter, sat dense et subseriatim punctatis, 
punctis paullo pone medium minutis; corpore subtus pedibusque 
flavescentibus, antennis obscure testaceis, quam corpore paullo 
brevioribus. Long. 8 mm. 
Hab. Tasmanta: Hobart and Launceston (Walker). 
The prothorax is about one-fourth longer than its greatest 
breadth; it is feebly tubercled at the middle of each side, and 
slightly constricted both a little in front of and behind these 
tubercles; above it is rather thickly punctured, and is without 
definite smooth spaces. The elytra are rather strongly and thickly 
punctured from the base up to the beginning of the posterior dark 
brown band, with the punctures arranged in tolerably regular 
rows; beyond this point the punctures are much smaller, and 
towards the apex become obsolete ; the yellow portion of the elytra 
between the post-median band and the ante-median plage is in the 
form of a transverse band, which is produced anteriorly along the 
suture, gradually narrowing in front until it joins the basal yellow 
portion. 
The two examples taken by Mr. Walker are both 
females ; so that, until the male sex is known, the species 
can only be provisionally placed in Sisyrium.

The Callidium diversicorne of White, which is here 
placed as a synonym, is to be found in the Catalogue of 
Gemminger and Harold under the genus Ceratophorus, 
to which it is in no way allied. The locality (New Zea- 
land) given by White, is probably erroneous.
