546 NEAV SPECIES OF AUSTRALIAN COLEOPTERA, 



dense; in the males, however, the scales are sometimes sooty with 

 a sprinkling of white scales. The elytra of the $ are dark brown, 

 of the 9 pale brown; the abdomen is somewhat paler in the 9 

 than in the $. Specimens may be taken occasionally under sea- 

 weed, but abundantly about plants growing justal)Ove high-water 

 mark ; during the day they remain concealed just under the 

 surface, but move about freely at night. I have taken specimens 

 just under the surface several yards away from any plant both at 

 Fremantle and Albany. The species does not appear to extend 

 so far north as Geraldton, as I have unsuccessfully searched there 

 for it on a number of occasions. 



Phycosecis algarum, Pasc. — I have a specimen from Sydney 

 agreeing with the description of this species (originally described 

 from Melbourne). It appears to be but slightly different from 

 lltoralis and is possibly only a variety. 



Phycosecis ammophilus, n.sp. 



(J. Rather narrow, slightly convex. Black; prosternum and 

 legs reddish. Prothorax densely clothed with large silvery scales, 

 a roundish patch at apex greyish; elytra with short, stout, setose, 

 silvery scales in regular lines not concealing derm; prothorax and 

 elytra fringed with white setose scales; under surface, legs and 

 head with sparse short whitish sette. 



Head densely punctate, feebly longitudinally grooved, a semi- 

 circular ridge in front Protliorax slightly transverse, base 

 rounded, apex produced and partially overhanging head, anterior 

 angles slightly produced; densely punctate, punctures concealed: 

 base with a feeble longitudinal line or groove. Elytra subovate, 

 not much wider than and about once and one-half the length of 

 prothorax; densely and strongly punctate, each puncture contain- 

 ing a scale. Under surface finely punctate. Length 14, width 

 1 (vix) mm.
