224 MEMOIRS OF THE QUEENSLAND MUSEUM . 
Forewing with 1st cubital cell subequal with 2nd in length and 
clearly longer than broad ; 1st transverse cubital vein set at much 
less than a right angle to the 2nd. [Palps of mouthparts generally 
much reduced ; antennae short, subclavate, with regular annular 
segments. Preapical spines to middle and hind tibiae very short. 
Forewing generally with 4 cubital cells of which the 2nd receives 
both recurrent veins. Propodeum strongly emarginate behind in the 
middle leaving a large blotch as in Acordulecera.] 
Genera : Acorduleceridea Rohwer, Giladeus Brethes, Lagideus Konow and 
Paralypia Kirby (South American Region) Paralypiin^ subfamily new. 
6. Antenna short, not more than 8-segmented, tending to become clavate ; 
segments normal. Propodeum not emarginate behind. 
Genera : Incalia Cameron, Parasyzygonia Rohwer, Syzygonia Klug and 
Syzygonidea Ashmead (South America Region) Syzygoniinae. 
Antenna long, many segmented (15-22) ; each segment broader apically 
than basally so that it is triangular in shape. Propodeum emarginate 
behind, leaving a blotch, though this is sometimes chitinized and not 
easy to distinguish. 
Genera : ? Cerospastus Konow (Chile) and Philomastix Froggatt (E. 
Australia) Philomastigin^e. 
STYRACOTECHYS genus, nov. 
Small broad species (about 4 mm. long). 
Head very little developed behind the eyes (fig. 9a) ; mouthparts normal 
with 4-segmented labial and 6-segmented maxillary palps ; eyes converge in 
front so that malar space is but linear ; labrum asymmetrical, and produced 
on the right side ; clypeus very short (shorter than length of pedicel) ; antennae 
very close to hind margin of clypeus (at a distance of about half length of 
pedicel) : antenna short (flagellum being about as long as the breadth of the 
head) ; funiculum and pedicel broader than flagellar segments and about as 
broad as long ; flagellum not increasing in breadth apically ; basal flagellar 
segments viewed from the side, with apical margin concave, and with a 
prolongation beneath (fig. 9b) ; frontal area with furrows obsolete ; ocellar 
region slightly raised ; ocelli arranged nearly in a line, the triangle being very 
broad based ; behind the two hind ocelli is a carina. 
Thorax. — Pronotum without a clear accessory suture ; sternauli separating 
mesepisternum from mesosternum well developed ; third pleural suture ungulate 
in the middle, the angle pointing backwards. Wings as in Diphamorphos Rohwer
