A NEW NEOTROPIGAL GENUS OF REDUVIID.^ 



bj E Kergroth 



In describing the genus Ixopus in my paper on Bornean Redu- 

 viidse (Sarawak Muséum Journal I, 3, p. 25-38) I mentioned an 

 undescribed genus of the subfamily Zelinaî having, like Ixopus and 

 the Apiomerinse, the legs clothed with hairs exuding a gluey tluid. 

 The two species forming this genus are both from French Guiana 

 and, being big and showy insects, it is curious that they bave 

 remained undescribed until now. Judging from the long hemelytra 

 and wings they are strong flyers and when on the wing possibly 

 simulate certain large neotropical wasps with dark metallic wings. 

 Their strong sticky legs and partly curved tibise make them power- 

 ful enough to get the better of even large insects, such as wasps, 

 Asilids and dragon-flies. In contrast to Ixopus this genus bears no 

 resemblance (apart from the legs) to the Apiomerinœ.
