and Gyrinidae of Australasia. 417 



I am indebted to Dr. Schaum for a typical example of this species 

 from the cabinet of Germar.

19. H. multimaculatus, n. sp. 



H. ovatus, subparallelus, sat latus, valde punctatus, flavo-ferrugineus, 

 elytris nigro maculatis. 



Long. corp. 1 lin., lat. \ lin. 



Subparallel, thickly and coarsely punctate throughout, impubescent, 

 in colour flavo-ferruginous : head finely punctate, rufo-flavous, the basal 

 line being fuscous : the sides of the thorax are parallel, the surface 

 thickly punctate ; between and connecting the fovea3, near the basal 

 line, is a well-defined transverse fovea ; the. surface in colour is flavo- 

 ferruginous, the margination and anterior margin being narrowly fus- 

 cous, and the basal line more broadly so, with a dark conspicuous cloud 

 of fuscous situated medially and extending to the anterior margin ; the 

 black basal marking extends on either side only to the lateral fovea : 

 elytra subparallel, thickly and coarsely punctate, in colour flavo-fer- 

 ruginous, with thickly scattered fuscous markings ; these markings are 

 sometimes isolated, subcircular in form, and minute ; sometimes, espe- 

 cially transversely, post-medially, they are confluent, and give an appear- 

 ance of a transverse band ; they present also the appearance of a longi- 

 tudinal marking near to and parallel to the suture, and it is probable that 

 in different examples the degree of these markings may differ : legs and 

 antenna flavous. 



H. multimaculatus is closely allied to H. sinuatocollis ; the macula- 

 tions on the elytra are more numerous, and the sides of the thorax 

 are parallel. It corresponds more closely still to pale examples of 

 H. Meaclfootii ; it is longer in form, the transverse thoracic fovea is 

 much more abrupt and distinct, the punctations of the surface are 

 deeper, and the maculations of the elytra are smaller, more nume- 

 rous, and less confluent. 



I possess a single example of this species, received some years 

 ago from Mr. Stevens : locality " South Australia." 



20. H. Ransarclii, n. sp. 



H. oblongo-ovatus, postice attenuatus, crebre punctatus, niger, flavo 

 maculatus. 



Long. corp. 1\ lin., lat. ^-f lin. 



Oblong-ovate, parallel, somewhat attenuated at the apex, thickly and 

 deeply punctate, black : head with two small punctations between the 

 eyes, black, with a medial longitudinal line of dark rufous : thorax 

 broad, subparallel, in front the anterior angles rounded ; the surface is
