t.O [March, 



13. — Dianous tortuosus, n. sp. 



Black, with a brassy lustre in certain lights, tbe under surface obscure 

 cvaneous ; shining, very sparsely, finely pubescent. Head moderately broad, 

 closely, rather coarsely punctate, the intra-ocular grooves deep ; eyes not very 

 large ; antennae long. Prothorax narrow, about as long as broad, the sides 

 rounded anteriorly and parallel at the base ; closely, rather coarsely punctate, 

 depressed and rugosely punctured posteriorly, grooved down the middle an- 

 teriorly, and with a very deep oblique sulcus on each side, the sulci extending 

 inward to the basal depression, which is finely carinate in the centre. Elytra 

 much wider than the head, subquadrate, rounded at the sides posteriorly, about 

 as long as broad ; coarsely, rugosely, confluently punctate, depressed along tlie 

 suture auteriorly and within the humeri, and with a broad, transverse, sub- 

 median depression, the sculpture in these spaces strongly vorticose. Abdomen 

 closely, minutely punctate, the sixth segment with coarser punctures ; ventral 

 segments uniformly punctured ; anal brushes long. Legs moderately elongate, 

 the tarsi not very slender, the fourth joint without definite lobes. 



c? . Fifth ventral segment feebly, the sixth deeply, emarginate, the fifth 

 depressed in the middle behind. Genital armature (fig. 8) : lateral lobes long, 

 slender, slightly sinuate, pilose towards the apex within ; median lobe dilated 

 and broadly bifurcate at the tip, the apex deeply emarginate. 



Length 6-6^ mm. ( c? $ •)

Ten specimens. More rugose than D. cameroni, the legs shorter 

 and not so slender, the antennae shorter, the elyti-al sculpture strongly 

 vorticose, the fourth tarsal joint simply excavate at the apex, without 

 definite narrow lobes. Compared with the abundant D. radiatus, the 

 present species has the elytral sculpture less coarsely vorticose, the punc- 

 turing of the head and prothorax closer, the eyes not so large, and the 

 S armature very different. 



14. — Dianous sithvorticosus, n. sj). 



Black, with brassy and bluish reflections in certain lights, the antennae 

 and palpi black, the under surface uigro-cyaneous ; moderately shining, finely 

 pubescent, cinereo-variegate on the elytra. Head not verv lai'ge, closely punc- 

 tate, the intra-ocular grooves deep ; eyes rather large ; antennae moderately 

 long. Prothorax much narrower than the head, about as broad as long, rounded 

 at the sides anteriorly, constricted before the base; closely, rather finely punc- 

 tate, with a deep oblique groove on each side of the disc and a short median 

 sulcus between them. Elytra subquadrate, rounded at the sides posteriori v, 

 much wider than the head, about as long as broad ; densely, rather coarsely, 

 rugosely punctate, longitudinally depressed near the suture anteriorly and 

 within the humeri, with a transverse, rather broad excavation just behind the 

 middle, the sculpture in this space and along the suture in front of it vorticose. 

 Abdomen densely, minutely punctate ; ventral segments uniformly punctured ; 

 anal brushes long. Legs moderately elongate, the tarsi comparatively stout.
