3. CLOSTEROCERUS WESTWOODI new species. 



Female: — Length, 1.30 mm. 



Dark metallic green, the abdomen, head and legs dark blue, the tarsi and first two 

 tibiae whitish. Parapsidal furrows distinct but cephalad near the pronotum turned off rather 

 abruptly laterad not reaching the pronotum. Agrees otherwise with mints but the bands of 

 the fore wing are blacker, the apical one covers nearly the whole of the apical edge of the wing 

 while the proximal blotch is replaced by a distinct loop or hook-shaped black marking which 

 leaves the marginal vein a little distad of its middle, runs a rather short distance disto-caudad 

 and then curves rather sharply at right angles to the caudal margin running diffusely along 

 this proximad over half way to base. Scutellmn longer and less rounded at apex than as with 

 mirus. Mandibles tridentate. First two tibiae dusky just below knees. 



From one female caught in jungle, May 2, 1914 (A. P. Dodd). 



Habitat: Tweed Heads (Tweed River), New South Wales. 



Type : No. Hy 2538, Queensland Museum, Brisbane, the specimen on a slide. 



Dedicated to John Obadiah Westwood. 



4. CLOSTEROCERUS ROSTANDI new species. 



Female: — Length, 1.20 mm. 



Bright metallic green, the abdomen except at base above, legs and the antennae dark blue, 

 the tarsi white. Parapsidal furrows curving off before reaching pronotum, the thorax densely 

 scaly. Postmarginal vein as long as the stigmal. Characterized by the fore wing which is 

 without stripes, only with a distinct black substigmal spot which, however, nearly reaches caudal 

 margin opposite but fades rapidly from the middle of the wing, the latter broad. Mandibles 

 bidentate. Funicle joints subequal, subquadrate, larger than the club joints taken separately. 

 Terminal spur of club distinct. Hind wings with about 11 lines of discal cilia where widest. 



From one female caught May 30, 1914, in forest (A. P. Dodd). 



Habitat: Maclean (Clarence River), New South Wales. 



Type : No. Hy 2539, Queensland Museum, Brisbane, the specimen on a slide with slide 

 type of Parahorismenus spissipunctatus Girault. 



Dedicated to Edmond Rostand. 



5. CLOSTEROCERUS CURTISI new species. 



Female: — Length, 1.25 mm. A most beautiful species. 



Agrees with the description of westwoodi but the propodeum is also blue. Wings like 

 Ihose of westivoodi but the second band is distinctly caret-shaped, the apex of the caret jointed 

 distinctly along center of blade to the middle of the apical or third cross-stripe, forming more 

 • or less distinctly the letter K. Also the first caret-shaped band is exactly similar to that of
