elongate pedicel. Scape yellow except at apex above. King-joint 2 extremely short, the other 

 three large. Mandibles bidentate, tooth 2 broadly truncate. The yellow of abdomen at side 

 of base is distinct but less than a sixth of its length. The spot above at base of abdomen 

 also shorter than in the compared species. 



From one female caught in forest, May 15, 1914 (A. P. Dodd). 



Habitat: Chindera (Tweed Elver), New South Wales. 



Type: No. Hy 2633. Queensland Museum, Brisbane, the specimen on a tag; head on a. 

 slide. 



Compared with type of the Trichaporoides. 



Genus EPENTASTICHUS Girault. 

 1. EPENTASTICHUS WALLACEI new name. 

 Aprostocetus sexguttatus Girault, preoccupied. 



Female: — Length, 0.S0 mm. 



Agrees with the description of Epcntastichus flavella but only the meson of propodeum 

 is dusky, the body is golden yellow, the abdomen bears three roundish marginal dots on 

 a little over proximal half and is dusky across base narrowly. Also funicle 1 is shortest, 

 quadrate, 2 and 3 somewhat longer than wide, each somewhat shorter than the pedicel which is 

 somewhat shorter than with flavus. An oblique dusky stripe along cephalic margin of 

 propodeum on each side of meson. Otherwise, like flavus. Club with a short terminal sjiine. 

 Mandibles tridentate. Propodeum with a median carina. Wings broad. Hind wings with 

 about five lines of discal cilia where widest. 



From one female captured in forest, April 15, 1914 (A. P. Dodd), Cloncurry, Queensland.. 



2. EPENTASTICHUS QUADRIMACULiS new species. 



Female: — The same as wallacei but the abdomen bears ouly two of the marginal 

 dots, the proximal two, and the body is a third larger. 



From one female captured with the above (wallacei), April 15, 1914. 



Habitat: Cloncurry, Queensland. Forest. 



Type: No. HyS63S. Queensland Museum, Brisbane, the specimen on a slide. 



3. EPENTASTICHUS FLAVELLA new species. 



See antea (these Memoirs, II), p. 243, Epentastichus flavus (Girault) which, together 

 with Quadrastichodes flaws Girault, is a nomen nudum. Additional characters are: Length, 

 1.18 mm. Antennae inserted a little above the ventral ends of the eyes. Mandibles tridentate. 

 Marginal cilia of fore wings short. Scape long, compressed. Club terminating in a nipple.- 

 The type is a head on a slide. The type female was captured on forest downs, July 14, 1912. 



Genus SYNTOMOSPHYBELLA Girault. 

 1 SYNTOMOSPHYRELLA FUSCIPENNIS Girault, 



One female, type locality, December 4, forest. Compared with type. The head is more 

 or less brownish and the postmarginal vein really only a fourth the length of the stigmal. The- 

 species resembles Selitrichodelia fuseipennis. 



This species must stand as it is though it is exceedingly similar to Selitriclwdelia 

 fusdpennis. Yet the latter is said to have a solid club and a groove on the scutum. Both 

 species have a short propodeum at meson which bears a complete median carina (very short) 

 and no others. The wings are identical but distinctly broader in the Selitrichodelia and the-
