144 Mr. T. D. A. Cockerell — Descriptions and 



second t.-c. straight. Legs entirely dark, witli thin pale 

 hair. Abdomen flattened, dull at base, more shining apieally, 

 ■with black hair. Under the microscope the sculpture o£ 

 the thorax above is seen to consist of a veiy minute net- 

 Mork, the meshes elongate ; there are no punctures. 



Hab. Sydney, New South Wales, Nov. 29, 1910 (/F. W. 

 Froggatt,'l^2). 



Unfortunately tlie specimen was broken in transit and the 

 antennae lost. 



Very close to E. geminata, Ckll., but differing by the 

 absence of yellow spots on the abdomen, the darker nervures, 

 and the much longer second submargiual cell. Also related 

 to E. quadrimaculata , Smith, which has four yellow spots on 

 the abdomen. These insects closely resemble species of 

 Prosopis. 



Meroglossa {sulcifrons subsp. ?) persulcata, sp. n. 



^ . — Length about 9 mm. 



Black, with the face deeply sulcate on each side of the 

 clypeus, the middle of which is strongly elevated; face- 

 marks creamy -white; thoracic markings (consisting of 

 tubercles), a large rounded patch behind, scutellum and 

 postscutellum (but not axillae) bright chrome-yellow; light 

 marks of face consisting of elevated part of clypeus, a large 

 triangular patch on each side, a supraclypeal dot, and lateral 

 face-marks, ending in a broad truncation a little below 

 middle of front; there is a dark shade on each lateral mark 

 next to the eye : malar space, labrum, and cheeks black ; 

 tongue slender and pointed ; maxillary palpi very long ; 

 scape black ; flagellum dark red beneath, the last joint 

 pointed ; front depressed, smooth and shining above autenme, 

 but beyond this punctate ; mesothorax shining, strongly 

 punctured ; basal area of metathorax longitudinally finely 

 ridged or striate ; legs black, with some of the hair shining 

 silvery ; tegulie piceous, with a yellow dot. Wings dusky, 

 nervures and stigma dark brown, second s.m. receiving both 

 recurrent nervures. Abdomen shining, conspicuously punc- 

 tured, punctures on first segment conspicuously finer than 

 those on second. 



Hab. Southern Queensland [Froggatt, 36). Certainly very 

 near to Meroglossa sidc'ifrons {Prosopis sulcifrons, Smith), 

 but the lateral face-marks of sulcifrons are much more 

 reduced. The large white area on clypeus in persulcata is 

 long and narrow, a truncated cone, not *' bell-shaped " ; the 

 wings of persulcata are distinctly dusky, not "hyaline . . . 

 their extreme apex slightly clouded." It is possible, how- 

 ever, that persulcata is a race of sulcifruus.
