142 Mr. T. D. A. Cockerell — Descripiions and 



posterior apical corners of the secoud to fourth reddish 

 orange or orange ferruginous. 



Hub. Sydney, New South Wales, at flowers of Angophora, 

 December 1, 1910 {W. W. Froygatt, 111). 



Known from all the other Padujprosopis by the black 

 abdomen with light apex. On account of the small size, 

 and quite different sculpture of head and thorax, I cannot 

 regard this as the female of P. angophora. Two specimens 

 were sent. 



Pachyprosopis humeralis, sp. u. 



(^ . — Length about 4^ mm. 



Black, the abdomen very dark brown, with yellow bands 

 at the extreme bases of the second to fourth segments, or 

 only on the second ; face below antennje, labrum, mandibles 

 (except tips), cheeks (ending some distance below top of 

 eye), scape and frontal mark, all brilliant chrome-yellow ; 

 the frontal mark, connecting with the supraclypeal, is large 

 and circular or subquadrate ; the yellow lateral marks 

 extend above the level of the antennse very broadly, with a 

 further linear extension along the orbit, the whole like a 

 hand with the index-finger pointed ; flagellum dull yellowish 

 beneath ; third antennal joint extremely short, a mere ring, 

 fourth twice as broad as long ; facial foveae linear, sharply 

 pointed above ; upper part of head and thorax dull, rather 

 coarsely microscopically tessellate, with scattered punctures ; 

 the broad base of metathorax more shining, with a micro- 

 scopic cancellation; upper part of thorax all black, except 

 broad anterior corners of mesothorax, which are yellow, the 

 yellow ending in a sharp point over the tegulae ; sides of 

 prothorax, tubercles {except a dark dot), anterior part of 

 pleura, a small stripe invading mesopleura, and under side 

 of thorax all yellow ; legs yellow, the hind tibite with a dark 

 stripe ; hind legs quite normal ; tegulte pale testaceous. 

 AVings clear, nervurcs piceous ; first r. n. entering apical 

 corner of first s.m. ; second s.m. narrow, its upper apical 

 angle variably produced, but always essentially in tlie 

 Pachyprosopis manner; stigma large, sepia-brown. Abdo- 

 men broad, the apex ferruginous : venter yellow. 



Hab. Sydney, New South AValcs, three at flowers of 

 Angopliora, Dec. 1, lUlO (IT. TI'. FroggalL li:.^ = type, and 

 115 in part). 



Quite unlike all other Pac/iypi'osopis by its yellow 

 markings, in which it resembles one of the groups of Eury- 

 g/ossa. The head also is formed as in Euryr/lossa. The 

 abdomen has a minute transverse tessellation, but no distinct 

 punctures.
