Frosopis melanocephala n. sp. 

 Female. Length about 5 mm., head and thorax black, without light markings, 

 but flagellum bright chestnut-red ; leg.s black, the tarsi more or less reddish ; 

 abdomen shining chestnut-red, with a black patch on middle of first segment, and 

 the other segments more or less suffused with dusky medially, the basal part of third 

 and fourth segments slightly purplish ; tegulse black ; wings hyaline, stigma black ; 

 second submarginal cell broad, receiving recurrent nervures very near base and 

 apex ; clypeus broad ; face and front striato-punctate ; a slender groove (visible 

 under compound microscope) up middle of front ; mesothorax dull and closely 

 punctured ; base of metathorax coarsely rugose. 



Type from Darra. 14-10-13 [Hacker). Also from Brisbane, 14-11-12 (Hacker).- 

 A very distinct species, running out at 7 in my table. 



Frosopis ancorata var. subconstricta n. var. 

 Male. Length about 5 mm., face-marks cream-colour ; firs - abdominal 

 segment dark red. Very close to P. constricta Ckll., with the same face-markings, 

 antennae, &c.. but abdomen black with the first segment dark red (bright chestnut- 

 red at sides of base) and second with apical margin narrowly reddened ; tubercles 

 black with a slight red edge ; wings brownish. 



On flowers of Malaleuca preissiana, Brisbane [Hacker). P. ancorata appears 

 distinct from P. constricta Ckll., but the variety now described is intermediate, and 

 it will probably prove that all three are forms of a single species. 



Frosopis scintillans n. sp. 

 Male. Length hardly 3-5 mm., slender, clypeus, labru-m, mandibles, and 

 narrow bands along orbits (ending very slenderly about halfway up front) all white ; 

 scape and second antennal joint pale yellowish beneath, the rest of antennae pale 

 red beneath ; head round seen from in front ; mesothorax and scutellum dullish ; 

 the compound microscope shows vertex, mesothorax, and scutellum all with distinct 

 well separated punctures on a tessellated surface ; metathorax rounded, the broad 

 base with microscopic transverse lineolation, more or less joined to form tessellation, 

 but Avith no trace of plicae or rugae ; tegulse dark brown, wings hyaline, faintly dusky, 

 iridescent ; stigma dark brown ; second submarginal cell small, recurrent nervures 

 meeting the intercubitals ; upper border of prothorax dark, but tubercles apically 

 yellow ; anterior knees and tibiae very pale-reddish, the tibiae with a faint dusky 

 cloud ; middle and hind tibiae white or reddish-white at base and apex ; all the 

 tar.si light ; abdomen shining reddish-black, the venter simple. There is a very 

 small supraclypeal mark. 



Brisbane, 26-9-16 [Hacker). Goes to 34 in my table, and appears to be close 

 to P. scintilla Ckll., but with white face-markings. It may possibly be a subspecies, 

 of Scintilla.
