AUSTRALIAN TIYMENOFTEBA CJIALCIDOIDEA.—GIEAULT. 213 



OOTETRASTICHUS BEATUS Perkins. 



Synonym: The variety affinis of Dodd and Girault. 



There are on each margin of the abdomen a dot at base and four widiT 

 than long spots, the last spot at base of about distal third. The propodeum is 

 metallic except laterad of the spiracles. 



From specimens in the U.S.N.IM., reared from the eggs of PerkinsicJhi 

 saccharicida at Honolulu. 



TETRASTICHODES FROGGATTI Ashmead. 



This is a species of Aprostocetus. The original description is correct but 

 the scutum is concolorous (i.e. pale golden yellow) broadly at its cephalo-lateral 

 corner; the dot caudad on each parapside is longer than wide (and appears to be 

 on the acute apex of the much advanced axillai) ; it is cephalad of a line drawn 

 through the tegula^. The propodeum is concolorous laterad of the spiracle. The 

 spot at mesal base of the scutellum rounded. The black is really brown-black ; that 

 on the abdomen forms three rather distinct cross-stripes at the middle, all rather 

 broad. Propodeum with a median carina only. ]\Iarginal fringes of the fore wing 

 a little longer than usual. Stigmal vein tolerably long. Postscutellum dusky. 

 Scutum with a delicate median groove. Abdomen elliptical, narrower than the 

 thorax. Face of pronotum black. Caudal margin of propodeum carinated. 

 Mandibles tridentate. Fuuicle joints subquadrate but 3 longest, a little longer 

 than wide, slightly shorter than the pedicel, the latter dusky above at base. Club 

 with a distinct terminal nipple. A well-marked species. 



From three female types and nine paratypes in the U.S.N.M. A specimen 

 mounted as a male type was entirely black except the legs but the head was 

 missing. A female type head has been mounted on a slide. 



PSEUDIGLYPHOMYIA SILV-ffi new species. 



Female: — Length, 1.45 mm. 



Dull orange yellow, the postscutellum and the dorsal thorax laterad of it, 

 the pronotum, parapsides and coxie pale lemon yellow; fore wing infuscated 

 from apex to base of the marginal vein but a clear area extends along the whole 

 of the marginal vein and along the distal side of the stigmal vein. A U-shaped 

 marking over the centre of the occiput, a twice longer than wide spot on scutellum 

 just out from base at meson, median carina and a spot at mesal apex (caudad) 

 of propodeum : parapsidal furrows and grooves of the scutellum ; a dot at 

 extreme latero-cephalic angle of each axilla; cephalic margin of propodeum out 

 to the spiracle ; dorsal margin of caudal femur narrowly ; apex or more of stigmal 

 vein; and eight cross-stripes on abdomen, the first at base, the last across a 

 little before apex; stripe 4 is a double one (here counted as two), 7 and 8 

 are suffusedly connected along the meson, making a rather large black area. 

 Extreme lateral angle of pronotum (dorsal aspect) black. Body finely scaly. 

 Funicle 1 a half longer than wide, 2 a little shorter, longer than the pedicel 

 which is somewhat longer than wide at apex ; club joints 1 and 2 subquadrate 

 or a little wider than long; club with a terminal spine. Mandibles about 

 6-dentate. 



Described from a female captured by sweeping "fir" bushes, forest low- 

 land, Hawkesbury River, Brooklyn, New South Wales, November 9, 1914. 



Type: No. 77^/ 55.56', Queensland Museum, the specimen on a slide.
