pile; lateral edges of the coxae, the knees and apices of the 

 tibiae more or less yellowish ; the hind femora entirely, and 

 the four anterior more or less underneath, rufous ; the hind 

 tibiae more or less rufous beneath. The second cubital 

 cellule is longly pedunculated ; the second recurrent nervure 

 is almost interstitial ; tegulse red. 



The tibiae are not spined, nor the clypeus keeled ; the 

 metanotum is not bilobate. In some specimens there is a 

 small yellow mark on the sides of the third and fourth 

 abdominal segments.

4. Nysson erythropoda, sp. nov. (PI. IX., Fig. head 18, 

 i8 a antenna). 



Niger, argenteo pilosus, capite etthorace rugoso-pimctatis ; 

 antennis subtus pedibusque rujis, linea pronoti, tegulis, linea 

 scutelli macirtisque abdominis segmentis 1 — 2 flavis ; alts 

 fuscis. Long. 6*5 mm. 



Agrees closely with rugosus; differs in having the 

 antennae rufous beneath, the legs entirely red, except the 

 base of the coxae ; the base of the abdomen is not red ; the 

 yellow line on the pronotum is continuous ; the basal joint 

 of the antennae is more globular, thicker, and shorter ; the 

 second is not much shorter than the third; the eyes are 

 more curved, the ocelli more raised ; the mesopleurae at its 

 hinder edge has a stout keel interrupted in the middle, and 

 prolonged beneath near to the sternal groove ; the hypo- 

 pygium is more sharply convex in the middle ; the second 

 cubital cellule is longer, being as long, on the lower side, as 

 the third, whereas in rugosus it is clearly shorter. 



The clypeus is bi-dentate at the apex ; the mandibles 

 and palpi obscure rufous ; there are four keels on the median 

 segment; its sides are densely covered with pale pubescence; 

 its spine is blunt ; the white pile on the tibiae is very dense, 

 almost hiding the color.
