157. — Physol(esthus geandtpalpis. n. sp. 



Lensrth 21 lines 



Brownish black, subnitid and of rather flattened form. Head 

 as in the last species, with the last joint of the palpi large and 

 obliquely truncated. Thorax rather transversal, with the anterior 

 angles advanced, the posterior square and slightly reflexed, the 

 median line deep, and the basal impressions broad and long. 

 Elytra of an elongated ovate form, strongly striated and with 

 the interstices convex. Legs, antennas, and palpi reddish. 



This completes the Garabidce in the Gayndah collection, with 

 the exception of five species of Glivina. These I cannot venture 

 to name as I have been unable to procure the works of M. Putzeys, 

 who has paid special attention to this group, and who has de- 

 scribed, I believe, a large number of Australian species.

158. — Hydroporus bifasciatus. n. sp. 

 Length 2 lines. 

 Ovate, subconvex, covered with a close puncturation, and of a 

 testaceous red colour. Head bordered in front, and with a very 

 short oblique lightly impressed line at the inner and anterior 

 angle of the eyes. Thorax broad, short, narrowly margined on 

 the sides, and broader behind than in front, with tbe anterior 

 angles advanced, the posterior subacute, the base slightly bisinuate 

 on each side, and a large patch of a dark brown colour on 

 each side of the central lobe. Elytra broader than the thorax, 

 rounded at the humeral angles and on the sides, and narrowed and 

 rounded at the apex, with a very zigzag black fascia about the 

 middle, extending from the suture to near the sides, and another 

 of the same hue, and rather broader near the apex, extending 

 from the sides almost to the suture, the two fasciae being joined 

 near the suture, and nearly joined about the middle of the width. 

 On each elytron may be traced an obsolete stria a little way from 

 the suture, and also a number of small round obsolete looking 

 depressions. The tarsi of the male are black and much dilated, 

 the third joint being the largest.
