EXOCIIUS. 297 



and not very shining, punctulate, black, with the superficial 

 notauli and a broad central vitta flavescent. becoming centrally 

 red ; mesopleura? flavous, with a basal fascia and a broad 

 line below radices black ; mesosternum testaceous, with the 

 interpectoral sulcus black ; metathorax glabrous and rufescent, 

 with its base punctulate and black ; areola strong to the con- 

 spicuous costulse, thence all arese are wanting. The convex and 

 punctate scutellum, its frenum and the postscutellura flavous. 

 Abdomen elongate-fusiform, broader behind centre, punctulate, 

 pilose, black, with apices of all the segments badious, or red, with 

 base of the basal three nigrescent ; basal segment strongly 

 margined laterally, and discally bicariuate only at its base ; venter 

 piceous. Legs bright stramineous, with only the pulvilli and 

 sometimes the hind trochanters blackish, hind coxso and their 

 tarsi reddish ; posterior calcaria very unequal in length. Wings 

 hyaline and not broad, radix and tegulae flavous, stigma and 

 nervures piceous ; basal nervures subcontinuous ; nervellus ante- 

 furcal and intercepted at its lower angle. 



Length 5 millim.

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

 Thomson (Deut. Ent. Zeit. 1887, p. 211), but much more profusely 

 pale-marked, with the petiolar carinse shorter, nervellus intercepted 

 lower, etc. 



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



211. Exochus flavicaput, sp. n. 



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

 niesothorax broadly, scutellum and legs, bright flavous ; hind 

 coxee black ; basal nervure not continuous. 



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

 differentiate them satisfactorily only by the metanotal arese and 

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

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

 disc) of the mesonotum broadly flavous, the mesopleurse only 

 centrally concolorous and the mesosternum immaculate black ; 

 the metathorax is entirely black, with only the basal lateral areae 

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

 both lateral carina3 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 COXEB and trochanters black ; the 

 nervellus is similarly 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. 



Lencjili 7 millim.
