strongly rounded, front angles produced and acute, hind ones 

 rounded off ; punctures rather small and not very dense, but 

 becoming denser in front and on parts of base. Scutellum 

 punctate on basal half. Elytra slightly dilated to beyond the 

 middle ; discal costae fairly well denned and bounded by 

 geminate rows of punctures, the interstices with punctures 

 much as on prothorax ; suture briefly mucronate. Pygidium 

 with dense punctures at base, small and sparse elsewhere. 

 Front tibiae strongly tridentate. Length, 22 mm.

Commencing near the base of each elytron there is a 

 dense even fringe projecting downwards; from the base itself 

 there is another fringe, but of longer and sparser hairs or 

 setae mostly projecting outwards. The basal joint of the hind 

 tarsi is fully as long as the second, but from most directions 

 it appears to be slightly shorter. It is much the build of 

 sol tela, of Blackburn's Group 4, whose elytra have similar 

 double fringes, but the prothorax is rather densely clothed in 

 front, and at the base has the long hairs characteristic of 

 Group 2 ; in the table of that group it would be associated 

 with latebricola, from which, as from all others of the group, 

 it may be distinguished by its clothing. 



Haplonycha suavis, n. sp. 

 PI. xxvi., fig. 56. 



Flavous and brightly iridescent, head, some marginal 

 parts, and teeth of front tibiae reddish. Sterna moderately 

 densely clothed with whitish hair. 



Head smooth at extreme base, but with crowded punc- 

 tures elsewhere. Clypeus widely rounded and strongly up- 

 turned in front. Antennae nine-, club three-jointed ; fourth 

 joint the length of third and slightly shorter than fifth. 

 Penultimate joint of maxillary palpi slightly shorter than the 

 adjacent ones. Prothorax widely transverse, sides strongly 

 rounded in middle, front angles produced and not very acute, 

 hind ones obtuse, but not rounded off ; punctures very minute. 

 Scutellum impunctate at apex. Elytra slightly dilated pos- 

 teriorly; with rather small and not very dense punctures, 

 geminate rows and discal costae ill-defined; suture not 

 mucronate. Pygidium with fairly numerous punctures, except 

 at apex. Front tibiae strongly bidentate ; two basal joints 

 of hind tibiae subequal. Length, 17 mm.
