Astathes and allied Genera of Longicorn Coleoptera. 45 



13. Astathes perversa, sp. n. (PI. IV, fig. 3.) 



Reddish-testaceous ; antennce with the last eight joints more or 

 less deeply infuscate ; elytra metallic-blue from the base to a little 

 beyond the middle ; metasternum with a large black spot on each 

 side. Head rather closely punctured in front, less closely above. 

 Prothorax sparsely punctured, except on the centro-notal tubercle ; 

 the latter having the form characteristic of this section, but somewhat 

 less strongly raised than in the preceding species. Elytra rather 

 thickly punctured ; each with two short dorsal costse, in addition to 

 one alongside the suture. 



Long. 9 mm. lat. 4 mm. 



ffab. West Borneo, Pontianak. Type in coll.

This species seems to link the present section with the 

 next. The centro-notal tubercle is less raised, and the 

 transverse ridges between it and the sides of the prothorax 

 less broad and obtuse, than they are in the other species of 

 this section. By these characters, and by the more ex- 

 tended metallic-blue area of the elytra, as well as by the 

 presence of two tolerably distinct dorsal costse on each 

 elytron, the species may be distinguished from A. dimidiata, 

 Gory, to which it has a considerable resemblance in colour. 



SECTION III. 



Prothorax much narrower at the apex than at the base ; the lateral 

 tubercles short, gradually sloped in front, abruptly raised and some- 

 what sharply edged behind ; the centro-dorsal tubercle moderately 

 raised, somewhat pyramidal in form, sloped gradually in front and 

 prolonged to interrupt the anterior transverse groove, impressed on 

 each side in front with a deep horizontal pit. Elytra each with 

 three distinctly raised costae, in addition to an acute sutural costa.
