302 MEMOIRS OF THE QUEENSLAND MUSEUM. 



abdomen. The punctures on the scutum in brisbanensis are finer than those on the other two 

 species. In all of them, the cephalic ocellus is within the serobicular cavity. 



Male: — Not known. 



From two females taken January 17, 1912 and January 27, 1912 (H. Hacker). 



Habitat: Brisbane, Queensland. 



Types: No. Hy 27 id, Queensland Museum, Brisbane, the specimens on a tag. 



1. PERILAMPUS AQUILONARIS new species. 



Male: — Length, 1.50 mm. 



Agrees with Walker's saleius but the head and abdomen are dark blue and most probably 

 not that species; tibiae yellowish brown, tarsi yellow; femora concolorous ; thorax aeneous green. 

 Pore wings slightly stained throughout. Scape metallic green, also the pedicel; rest of antenna 

 rich brown; funicle 1 subquadrate, 6 somewhat wider than long. Head smooth but with con- 

 spicuous short pubescence. Axillae with only the extreme mesal angle punctate (usually some- 

 what more in the other species), the rest scaly and with a lateral aspect. Abdomen smooth. 

 Postmarginal vein twice the length of the stigmal or nearly, subequal to the marginal. Pro- 

 podeum with a median carina with foveas down each side of it, the first ones large, followed 

 laterad by smaller ones, the fourth transverse, then two with others following laterad bounding 

 the large impunctate area on each side of meson which is scaly, its edges just within the circle 

 of bounding foveas and carinate. 



Female: — Not known. 



Described from one male taken in forest, November 10, 1913 (G. F. Hill). 



Habitat: Port Darwin, Northern Territory. 



Type : No. Hy 2750, Queensland Museum, Brisbane, the specimen on a tag. 



8. PERILAMPUS RELIQUUS new species. 



Female: — Length, 2.75 mm. 



iEneous green, the wings hyaline ; head, abdomen, coxae and femora very dark blue-black. 

 Head smooth, also abdomen. Occiput finely, circularly striate. Caudal aspect, obscure pin- 

 punctures on abdomen dorso-laterad mesad of margins, this aspect consisting of but two 

 segments, the second or distal very small (really segments 2 and 3). 



Differs from queenslandensis in that the tibiae are not dark metallic but reddish brown, 

 washed along the middle dorsad with dark metallic green ; the antennae are not wholly dark but 

 the distal three funicle joints reddish brown ventrad, also base of club; the body is more robust, 

 the abdomen dark green, the scutum coppery. Differs from levifacics in that the ocelli are more 

 distinctly in a triangle, the tibiae are not dark metallic, the thorax is dark metallic green. From 

 aquilonaris in that the venation is dark, the flagellum mostly so, the upper face bare or nearly, 

 the tibiae metallic dorsad centrally. All four species have the disk of parapsides glabrous. 

 Funicle 1 slightly shorter than the pedicel, slightly wider than long, the others slightly 

 shortening in succession distad. 



From one female captured by sweeping swamp in forest, May 14, 1914 (A. P. Dodd). 



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



Type: No. Hy 2751, Queensland Museum, Brisbane, the specimen on a tag; antennae on a 

 slide. 



The species tasmaniensis measures 2.50 mm. ; australiensis, 3.25 mm. ; mittagongensis, 

 1.85 mm. The ' ' fiery red spots ' ' on tasmanicus Cameron are not red but merely highly metallic 

 spots which would vary. 1
