DESCRIPTIONS OF THREE NEW SPECIES OF ODYNERINiK. 287 



sides to the middle, which is bluntly rounded. Apex of metanotum 

 smooth, spcarsely punctured round the edges, the middle below with a 

 triangular transversely striated band ; the sides bluntly rounded, 

 without teeth. Base of metapleurae smooth above, sparsely punctured 

 below, the rest irregularly longitudinally striated. Propleura^ coarsely 

 punctured above, below irregularly slightly obhquely striated. Meso- 

 pleurae closely, deeply, strongly punctured $ . Total length 

 15 mm. 



Base of pronotum transverse, narrower than the head. Post- 

 scutellum very shghtly raised above the level of the flat scutellum. 

 Sides of metanotum at the base reticulated. Basal segment of abdo- 

 men large, cup-shaped, not much larger than the second. Antennal 

 hook, slender, reaching to the base of the eleventh segment. 



Allied to R. argentatum, metallicum, and maldivense ; it wants 

 the dense white silky pile and the white mark on the top of the 

 clypeus of these species ; it is larger and stouter than most of 

 the examples I have seen of them, the post-scutellum is more 

 distinctly, gradually narrowed from the base to the apex, the 

 base of the thorax is more sharply transverse and the punctura- 

 tion is stronger. 



Rliijncldum fiikaii, sp. n. 



Rufo-testaceous, the clypeus, a large mark twice wider than long, 

 transverse above, broadly rounded below on the lower part of the 

 front and a line on the lower part of the eye incision, lemon-yellow ; 

 the following parts are black : the face and the part betw^een the 

 antennce, the front except along the eyes, the lower outer part sharply 

 projecting towards the eyes, roundly narrowed above and enclosing 

 the lower ocellus, the part enclosing the ocelli, except for a curved line 

 outside the ocelli ; the occiput, the outer edge of the outer orbits, 

 the inner more narrowly, a broader oblique line, uniting the two at 

 the top of the eyes, the base and apex of mesonotum broadly, more 

 or less of the sides, the metanotum wholly or in part, the greater 

 part of the pleurse, the mesopleurai with a large pyriform, rufous 

 spot at the base above, the greater part of the basal two abdominal 

 segments, the line on the second narrowly laterally, the base of the 

 third and fourth and the basal three or four ventral segments, black. 

 Legs coloured like the body, all the coxae and trochanters, the base 

 of the four anterior femora and the hinder entirely black. Wings 

 rufous hyaline, the apex violaceous. 3 • Length 14 mm. 



Clypeus longer than wide, broadly rounded above, the apex with 

 a shght but distinct incision. Front and, to a less extent, the vertex, 

 densely covered with fuscous pubescence. Apex of post-scutellum 

 broadly rounded. Apex of metanotum closely, somewhat strongly 

 obliquely striated, the sides margined above, the middle with a large 

 upper and a smaller lower spine. The apices of the abdominal 

 segments are more strongly punctured than the base, especially the 

 middle ones, which have the apices depressed, with the extreme apex 

 slightly reilexed. 



Allied to R. hcemorrhoidale ; it has the puncturation stronger 

 and closer ; the clypeus wider compared with the leugth, the
