OF NEW ZEALAND. 1015 



articulo ultimo quam prtecedente paulo longioreet tenuiore ; mcntum 

 latum vakle transvei'sum, anterius emarginatum. Antenna 9-ai'ti- 

 culatae, clava laxa elongata; inesosternum muticum ; femora subtus 

 pubescentia ; tarsi posteriores nullo modo remiformes, breves, subtus 

 pubescentes haud rigide ciliati, articulo basali brevissimo ; uiigui- 

 culi parvi simplices. Pronotum basi obsolete marginato ; elytra 

 striata. 



This genus consists of insects having the appearance and colora- 

 tion of convex PhUydri, but is more nearly allied to Hydrohius, 

 from which it differs by the more feeble palpi, broad and emarginate 

 mentum, unarmed mesosternum, and by the more laxly articulated 

 tarsal joints, furnished beneath with pubescence instead of rigid 

 cilia3. Although very different in size and appearance from the 

 genus Anaemia, the systematic characters bring the two near 

 together ; but Sai^liydrus has striate elytra, and the inflexed 

 epipleura is pubescent for all its length, and marked off" by a raised 

 line extending four-fifths of the length of the wing-case. It comes 

 equally close to Bygmodus, but the claws are small, with indistinct 

 basal lobe. 



The genus will probably prove peculiar to New Zealand. The 

 nearest ally I know of to it is a Chilian genus not yet described. 



I have at present included in the genus insects having glabrous 

 and others having punctate-pubescent femora ; it is probable, how- 

 ever, that it will prove a correct course to ultimately separate the 

 former as a distinct genus, between Sapliydrus and Bygmodus ; 

 but, as the few species known to me appear to indicate that the 

 sculpture of the femora may, when more species are known, not 

 prove a sufficiently definite distinction, I do not think it necessary 

 to propose two genera at present. 



The four new species known to me may be tabulated thus : —

Long., 5ium. ; lat., 3Jmm. 



The liead and thorax are closely and rather coarsely punctate, 

 shining, blackish, the anterior part of the clypeus more or less 

 flavescent, and the sides of the thorax yellow. Elytra densely 

 punctate, with a very fine indistinct pubescence, and with eight or 

 nine rows of closely placed punctures, which are not very distinct 

 amongst the general punctuation, while the external are quite in-
