sternitisque 3-6 fascia transversa flavis ; alis flavo-hyalinis, venis 

 ferrugineis ; clypeo apice dentibus tribus minutis armato ; 

 seginento mediano area basali nitida, impunctata ; sternito 

 secuudo area basali elevata nulla ; petiolo latitudine lougiore ; 

 sternito sexto angulis apicalibus dente armato. 

 Long. 13 mm. 



<$ . Antennae inserted a little more than half as far again 

 from the anterior ocellus as fi*om the hase of the clypeus ; 

 the interantennal carina short, but strong ; face below the 

 antennae and the clypeus with large sparse punctures; middle 

 lobe of the clypeus much longer than its greatest breadth. 

 Apical joint of the flagellum distinctly, but not very strongly 

 curved, scarcely longer than the penultimate, and truncate at 

 the apex. Vertex, temples, mesonotum, and rnesopleurse 

 closely and rather strongly punctured ; scutellum and median 

 segment rather less closely punctured ; postscutellum very 

 sparsely punctured. Abdomen rather deeply but not closely 

 punctured ; the first segment longer than its greatest breadth 

 and strongly narrowed at the apex ; sternites smooth ; 

 pygidial area parallel-sided, nearly twice as long as broad, 

 truncate at the apex, sparsely punctured. 



Hub. Tonkin ; May, 1917. 



The spines at the apex of the sixth sternite are short, the 

 species resembles C. vijilans, Sin., in the form of the clypeus 

 and pygidial area. 



Philanthus angustatus, sp. n. 



d . Niger ; clypeo apice anguste, macula curvata inter antennas, 

 pronoto margine postico, tegulis, callis humeralibus, scutello 

 macula magna, postscutello macula parva transversa, tergito 

 secundo macula apicali transversa utrinque, tergitis 3-5 fascia 

 angusta apicali, tibiis anticia intermediisque supra, tarsisque 

 flavis ; articulis tarsalibus apice nigris ; alis hyalinis, venis 

 nigris ; abdomine petiolato. 



Long. 10 mm. 



<$ . Clypeus very broadly rounded anteriorly, closely 

 punctured, and clothed with long whitish hairs, a row of 

 stout blackish setae springing from beneath the clypeus. 

 Head very closely punctured-rugulose, opaque; posterior 

 ocelli nearly twice as far from each other as from the eyes. 

 Antennae very little longer than the thorax without the 

 median segment, the apical joint rounded at the apex. 

 Thorax and median segment closely and rather strongly 

 punctured. Abdomen sparsely punctured ; first tergite more
