The submarginal vein in this genus is broken (statements to contrary notwithstanding). 

 Removed from Elachertini. 



1. SECODELLA DIVERSIPENNIS new species. 



Female: — Lengtli, about ].75 mm. 



Differs from all the species in having the postmarginal vein a little shorter tliau the 

 stigmal and the lines of ciliation on the fore wing are less distinct. Dark metallic blue, the 

 abdomen dark aeneous green, the abdomen ventrad suffused with brownish. Scape yellowish 

 brown, the proximal three tarsal joinfs whitish. Funicle joints all somewhat wider than long, 

 the last two a little the longest; pedicel longer than fimicle 1. 



From one female captured by sweeping in forest, February 16, 1912 (A. il. Lea and 

 A.A.G.). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. By 3505, Queensland Jluseuni, Brisbane, the specimen on a tag; head and a 

 pair of wings on a slide. 



2. SECODELLA PULCHRA ACUMINATA new variety. 



Female: — Length, 2.75 mm., e.xcluding oviiiositor which is extruded for a tliird the 

 length of the abdomen. 



Like jndehra Girault but the abdomen still longer. In both there is a distinct stylus 

 from apex of the abdomen which is not quite as long as the extruded portion of the ovipositor. 

 In lincata, this stylus is very short and the ovipositor valves are very slightly extruded (same 

 in rufiseapus, (liversipennis and cenea). 



From one female captured November 19, 1913 (H. Hacker). 



Habitat : Brisbane, Queensland. 



Type: No. Hy 3506, Queensland Museum, Brisliane, the specimen on a tag. 



3. SECODELLA ffiNEA new species of Girault and A. P. Dodd. 



Female: — Length, 2.60 mm. 



Like lineata Girault but the first joint of the funicle is longest, one third longer than 

 wide, 2-i gradually shortening, 4 plainly wider than long. Abdomen a little longer than the 

 head and thorax united. 



From one female caiitnred by sweeping in forest, .Tiily 24, 191.3 (A.A.G.). 



Haliitat: Gordonvale (Cairns), Queensland. 



Type: No. HyS507, Queensland Museum, Brisbane, the specimen on a tag, the head 

 or. a slide. 



OMPHALOMORPIIELLA new genus of Girault and A. P. Dodd. 

 Like OmphalomorpJta but the mandibles bidentate, the fore wings densely and normally 

 ciliate, the ring-joints large and distinct, the postmarginal vein very long and slender, some- 

 what longer than the marginal, over twice the length of the long stigmal. Pedicel elongate. 

 Marginal vein somewhat over half the length of the submarginal which is distinctly broken. 

 Propodeum with a ridge-like median carina. Abdomen depressed, from dorsal aspect rounded- 

 ovate. The male is the same but the abdomen with straight lateral margins, longer than wide.
