202 Mr. C *. Waterhouse’s descriptions 
Lepidoderma albo-hirtum, sp. nov. 
Oblongum, nigrum, dense albo-hirtum. Capite magno; 
clypeo brevi, antice rotundato, in medio leviter reflexo- 
exciso. ‘horace longitudine duplo latiori, convexo, antice 
angustato, lateribus rotundatis. Scutello apice rotundato. 
Iilytris basi thorace vix latioribus, postice paulo ampliatis, 
ad apicem deflexis. Abdomine supra cinereo. 
Long. 15 lin. ; lat. 7 lin. 
Thorax more narrowed in front than behind, the base 
obliquely truncate at each side, the posterior angles nearly 
rectangles. The elytra are a trifle more than three times 
as long as the thorax, not costate, the apex deflexed. 
Legs black, sparingly covered with long yellowish hair. 
Head, thorax, elytra, sides of the abdomen and the pygi- 
dium densely clothed with white scale-like hair, that on 
the sides of the abdomen finer. ‘The upper side of the 
abdomen is clothed with fine ashy pubescence; the meta- 
sternum with longer brownish pubescence. 
Hab.—Port Bowen. B. M. 
SERRICORNIA. 
Rhipidocera mystacina, Fab. 
The type specimen of this species in the Banksian 
Collection has the thorax entirely clothed with white 
pubescence, the abdomen maculate, and the elytra rather 
roughly sculptured. The specimens from Port Bowen 
agree perfectly with the type. The common form having 
the thorax spotted with white, I take to be merely a 
variety. The number of joints in the antennz of the 
$ examples from Port Bowen varies from 22 to 34; a 9 
example appears to have 18 jomts to one antenna and 19 
to the other. Specimens from Swan River, which I 
suppose to be &. pumilio, have black femora; one male 
example has 43 joints in the antenne. 
Specimens with the abdomen immaculate and with the 
elytra less densely and less strongly sculptured appear to 
belong toa distinct species, but I cannot satisfactorily name 
it from descriptions which I have seen.
