196 MEMOIRS OF THE QUEENSLAND MUSEUM. 



Genus SECODELLA Girault. 

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

 Removed from Elachertini. 



1. SECODELLA DIVERSIPENNIS new species. 



Female: — Length, about 1.75 mm. 



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

 stigma! and the lines of filiation on the fore wing are less distinct. Dark metallic blue, the 

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

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

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



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

 A.A.G.). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2505, Queensland Museum, 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., excluding ovipositor which is extruded for a third the 

 length of the abdomen. 



Like pulchra 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 lineata, this stylus is very short and the ovipositor valves are very slightly extruded (same 

 in rufiscapus, diver sipennis and cenea). 



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



Habitat: Brisbane, Queensland. 



Type: No. Hy2506, Queensland Museum, Brisbane, the specimen on a tag. 



3. SECODELLA 33NEA 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, 2-4 gradually shortening, 4 plainly wider than long. Abdomen a little longer than the 

 head and thorax united. 



From one female captured by sweeping in forest, July 24, 1913 (A.A.G.). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2507 , Queensland Museum, Brisbane, the specimen on a tag, the head 

 on a slide. 



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

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

 eiliate, 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 Bubmarginal which is distinctly broken. 

 Propodeum witli 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. 



1. OMPHALOMORPHELLA AURIPES Girault. Male, female. Genotype. 



Length, 2.70 mm. 



Bright ameous green, the wings lightly stained throughout, the coxae concolorous, the 

 legs rich golden yellow, also the scape except above at tip; rest of antenna black. Pedicel 

 nearly as long as the next four joints taken together, about twice the length of either joint 3 

 or 4 of funicle which are largest but distinctly wider than long; scape slender. Hind femur
