Allied to the variety of Exoclius iwnnotus, Grav., described by 

 Thomson (Dent. Eiit. Zeit. 1S87, p. 211), but much more profusely 

 pale-marked, with the petiolar carinae shorter, uervellus intercepted 

 lower, etc. 



Only two males of this beautiful species are known to me. 



211. Exoclius flavicaput, sp. n. 



J . A nitidulous black species with the head (except posteriorly), 

 mesothorax bi'oadly, scut ell um and legs, bright flavous ; hind 

 coxaj black ; basal nervure not continuous. 



So similar is this insect to the last species that I am able to 

 dilferentiate them satisfactorily only by the metanotal ax*eae and 

 alar neuration ; from E. coronelJm the present differs in having 

 no rufescent thoracic markings, the lateral sutures (but not the 

 disc) of the mesonotum broadly flavous, the mesopleurae only 

 centrally concolorous and the mesosternum immaculate black ; 

 the metathorax is entirely black, witii only the basal lateral area) 

 punctate, all the areaj entire with the areola apically strong, 

 both lateral carina) present and the petiolar area discrete ; the 

 abdomen is entirely black above with its basal segment bicarinate 

 to the centre ; the legs are bright stramineous with only the 

 pulvilli and whole of the hind coxoe and trociianters black; the 

 nervellus is sinnlarly intercepted, but the basal nervure of 

 the front wing is very distinctly postfurcal and for some distance 

 merged in the median ; and the size is distinctly larger.
