534 COLEOPTERA. 



antennal joint in the male of Sericospilus is almost exactly the same as that 

 of the third in Odontria halli, which has a pentamerous club. 



Fern. — Third antennal joint moderately elongate, its base attached to 

 the apex of the second, fourth and fifth short, both dentiform in front. 



Length, 13 mm. ; brcadtli, 7 mm. 



Glenhope. Two males found on the 18th July. 1915 ; one female after- 

 wards. Named in honour of Mr. T. Hall, who discovered all three 

 specimens. 



Xylostygnus Broun. Man. N.Z. Coleopt., p. 956. 



4060. Xylostygnus brookesi sp. nov. 



Suboblong-oval, moderately convex, nitid ; with numerous minute, 

 inconspicuous greyish setae above, its sides and basal joint of antennae 

 with some longer outstanding ones ; castaneo-rufous, slightly aeneous, 

 antennae paler. 



Head moderately closely and coarsely punctured, nearly smooth between 

 the eyes ; the clypeus more closely, wdth well-developed reflexed margins, 

 its sides narrowed anteriorly, the apex truncate. Thorax in the middle 

 about twice as broad as long but with the subacute anterior angles ex- 

 tending as far as the centre of the eyes, posterior angles rectangular, base 

 slightly bisinuate and finely marginate, the sides but little curved, some- 

 what sinuously narrowed behind the middle, sometimes slightly asperate 

 near the front ; discal punctation like that of the head but a little irregular, 

 not as close between the middle and sides, its a])ex smooth. Scutellum 

 broadly triangular, smooth behind. Elytra slightly broader than thorax 

 at the base, thrice its length, rather wider and gently rounded at the sides, 

 broadly truncate behind ; coarsely but not seriately jjunctured, sutural 

 striae obsolete. Pygidium vertical, hardly visible from above, not closely 

 punctate. 



Anterior tibiae bidentate and, like the longer tarsi, bearing some yellow 

 setae. 



Underside similar, with some elongate yellow setae on the femora and 

 front of prosternum, the latter with its triangular basal process acutely 

 projecting between the almost contiguous coxae. Metasternum coarsely 

 punctate towards the sides, nearly smooth and impressed along the middle. 

 Basal segment of abdomen almost covered by the femora, 2-5 slightly 

 diminish, with some linear longitudinal impressions, sixth very short. 



Differentiated from X. piceous (1723) by its somewhat shining aeneo- 

 rufous surface, less evenly rounded sides of thorax, rather more ])rominent 

 posterior angles, obsolete sutural striae of the elytra, and sHghtly different 

 sculpture. 



Length, 9J-10mm. ; breadth, 5.^ mm. 



Takapuna seaside, near Auckland ; 17th March, 1915. It bears the 

 name of its discoverer, Mr. A. E. Brookes, of Mount Albert. I have seen 

 three specimens, all but one without antennae, which are of normal struc- 

 ture, rather short, 9-articulate, the last three forming the rather short club. 



Group Dascyllidae. 

 Atopida White. Man. N.Z. Coleopt., p. 311. 



4061. Atopida villosa sp. nov. 



Oblong, slightly convex, covered with slender, very long, upright, 

 yellowish-grey hairs ; head, thorax, and scutellum dull, light chestnut-red ;
