and blunt. Thorax thickly covered with depressed golden pubes- 

 cence ; the sternum, the base of the meso- and metapleurse, the 

 space between the scutellums and the wings, and the base of the 

 median segment are black. The sides of the pronotum are broadly- 

 rounded behind ; the post-scutellum is raised above the level of 

 the scutellum, and is clearly separated from it by a wide, rounded 

 depression ; its top is smooth and shining. The metanotal tuber- 

 cles are large, prominent, bluntly rounded above ; the basal and 

 apical slopes are about equal in length. The wings have a slight 

 violaceous tinge..; the first and second transverse cubital nervures 

 above are separated by a slightly greater distance than the second 

 is from the third; the third transverse cubital nervure has a rounded 

 slope ; the first recurrent nervure is distinctly separated from 

 the transverse cubital ; the second is received shortly behind 

 the apex of the basal third of the cellule. Except for black marks 

 on the four posterior coxae behind and a broad black line on the 

 hinder femora, the legs are coloured like the body ; the single 

 tooth on the claws is large, stout, and curved. Abdomen black, 

 with a plumbeous hue ; the petiole luteous, black at the base and 

 apex ; the penultimate ventral segment is thickly covered with 

 long black hairs. 



This species is only represented by males. It is certainly not 

 the male of S. insularis, as apart from the marked difference in 

 coloration, the two differ in important structural characters not 

 of a sexual nature, e. g. in S. basimacula the post-scutellum is 

 raised above the level of the scutellum, which is not the case with 

 insularis. 



Salius willeyi, sp. nov. 



iMieus, abdomine nigro ; alis violaceis ; aniennis nigris, hasi

Long. 12 mm. 



Antennas black, the scape clear, the base of the flagellum dark 

 luteous ; the third joint is shortly, but distinctly, longer than the 

 fourth. On the head the vertex, the occiput, and the front, 

 except at the sides, are black. Eyes distinctly curved on the 

 inner side ; the ocelli form a triangle, the hinder are separated 

 from each other by a distinctly less distance than they are from 

 the eyes. Apex of clypeus broadly rounded. The apical tooth of 

 the mandibles is large, triangular; the lower oblique, not projecting. 

 Prothorax broadly rounded at the base. The thorax has the 

 following parts black : — the mesonotum except in the middle 

 behind, the space at the sides of the scutellums, the median 

 segment broadly on the basal half, the apex slightly in the middle, 

 the mesosternum, the lower half of the mesopleurse at the base, 

 and the metapleurae except at the apex. Post-scutellum and 

 scutellum roundly convex ; the former is large and is on a level 

 with the scutellum. The median segment is not transversely 

 striated; the tubercles are large and rounded. "Wings uniformly 

 fuscous violaceous, strongly iridescent; the cubital cellules are equal
