614 Capt. T. Broun on new 



Zeadolopus, gen. nov. 



Body compact, convex, short, oviform. Falpi short, 

 terminal joint oblong. Antennce 10-articulate, inserted 

 below the angles of the forehead ; their basal two joints stout 

 and almost equal, third rather longer than broad, slender at 

 base, the following three short, sixth quite transverse ; club 

 large, with four transverse joints. Head transversely quad- 

 rate, almost truncate, and finely margined in front. Eyes 

 moderately large, rather flat, distant from thorax. Lahrum 

 exposed and notched. Thorax broader than long, closely 

 adapted to base of elytra, its sides finely margined and but 

 little curved, apex widely but not deeply emarginate. Scu- 

 tellum large, triangular. Elytra short, not striate. Legs 

 short. Tibioi broad, the anterior with distinct spurs, the 

 others with straight apical calcars. Tarsi 5-]o'mted, the basal 

 four compact and nearly equal, fifth longer than the preceding 

 two taken together in the front pairs, but, owing to the longer 

 intermediate joints,- the last joint of the posterior seems 

 shorter ; they are finely pubescent ; claws slender. 



The antennal structure might seem to exclude this genus 

 from the Hydrophilid^B, but in habit, general appearance, 

 armature of tibial, and tarsal structure it is like other genera 

 of the family, and should, I think, be located near Tormus 

 and Adolojyus. 



Zeadolopus spinipes, sp. n. 



Convex, broadly oval, nitid, glabrous, rufo-piceous ; palpi 

 and antennae testaceous; club opaque, fuscous, densely and 

 finely pubescent ; legs reddish. 



Ihad moderately finely and not closely punctured, nearly 

 smooth behind. Thorax with very fine and rather distant 

 punctures on the disk, but becoming closer towards the 

 sides. Elytra not striate, but with series of distinct punc- 

 tures, which, however, become more or less obsolete on the 

 paler posterior portion, where there are fine sutural strias ; 

 interstices broad, with some small punctures on the basal 

 half. 



Tihice broad, the anterior with four or five slender spines 

 along their outer edge, the intermediate with more prominent 

 ones. 



Length 1, breadth | lino. 



Westport. 



Unfortunately one mounted specimen only is available, so 

 that the lower surface could not be satisfactorily examined. 

 It is from Mr. J. J. Walker^'s collection.
