256 Mr. C. 0. Waterhouse on Tasmanian Coleoptera. 



these parasitic Isopoda differ from other Crustacea in having 

 motile spermatozoa, which will be generally admitted to be 

 more improbable than the existence of hermaphroditism in a 

 parasitic animal. 



XXII. — Additions to the Coleojjterous Fauna of Tasmania. 

 By Charles O. Watekhouse. 



The following Coleopterous insects have just been added to 

 the national collection. In the collection from which they 

 were selected were specimens of Dorcadida biocularisj a species, 

 I believe, not previously recorded from this locality. 



MELOLONTHID^. 



Telura vitticoUis, Er. 



The male of this species appears never to have been 

 recorded. It differs from the female in having the eyes very 

 prominent, the club of the antennaj is composed of five long 

 leaflets instead of three, and the elytra are more narrowed 

 towards the base. 



HETEROMERA. 



Mordellafeltx, sp. n. 



Atra ; capite thora'ceque aureo-tomentosis, hoc vitta media et 

 utrinque puncto nigris ; elytris macula basali fasciisque duabua 

 (una ante medium angulata, secunda transversa ante apicem) 

 aureo-tomentosis ; pectore abdomineque albido maculatis. 



Long. 2 1 lin. 



Head and thorax clothed with golden pubescence, the 

 former with a distinct longitudinal impressed line on the 

 vertex ; thorax with a round black spot on each side, and a 

 central longitudinal black stripe which is interrupted ante- 

 riorly ; the posterior margin lobed in the middle. Scutellum 

 golden. Elytra with a short, scarcely oblique spot joining 

 the base near the scutellum, a well-marked fascia a little 

 before the middle in the form of a W, and a transverse spot 

 before the apex, all golden. Underside clothed with whitish 

 pubescence ; a triangular spot on each side of the basal abdo- 

 minal segments and the two anal segments black. Palpi, two 

 basal joints of the antennge, anterior femora and tibise, and 

 spurs to the posterior tibiae pitchy.
