T. D. A. COCKERELL. 223 



with pale ochreous hair-bands ; head a little broader than long ; man- 

 dibles largely dark reddish ; face covered with ochreous hair ; tongue 

 short, broad basally, rapidly narrowing to the finely linear apical part; 

 flagellum dull ferruginous beneath ; mesothorax and scutellum strongly 

 and closely punctured ; hair of thorax above short, pale ochreous, 

 dense on postscutellum and upper border of prothorax ; hair of pleura 

 shining yellowish ; area of metathorax ill-defined, plicatulate ; tegulse 

 small, shining dark rufous; wings dusky yellowish; b. n. meeting t. 

 m., its lower section only faintly arched (not at all as in Halictus)', 

 second s. m. rather large, receiving first r. n. a little beyond middle; 

 stigma large, dark reddish ; legs very dark reddish, the tarsi ferrugin- 

 ous ; hind legs slender, not deformed, the tibire somewhat produced 

 at apex in front, the projecting angle ferruginous ; first abdominal 

 segment much longer than broad, distinctly punctured ; on the other 

 segments the sculpture becomes more indefinite ; disc of fourth ven- 

 tral covered with ochreous tomentum. 



Not a typical Nomia ; it belongs to a Malayan group, and 

 is almost identical with A 7 ", ceratina (Sm.) from Sarawak ; N. 

 clavata Sm. from Gilolo is also allied. Perhaps all these 

 insects are geographical forms of a single species.
