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- 

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

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

 brown, the proximal three tarsal joint's whitish. Eunicle 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. Hy 2505, 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 rwfiscapus, 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 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, 2-4 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 3507, Queensland Museum, Brisbane, the specimen on a tag, the head 

 on a slide. 



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

 Like Omphalomorpha but the mandibjes 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. 



1. O.MPHALOMORPHELLA AURDPES Girault. Male, female. Genotype. 



Length, 2.70 mm. 



Bright Eeueous green, the wings lightly stained throughout, the coxaa 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
