MEMOIRS OF THE QUEENSLAND MUSEUM. 
Fore wings of moderate width, bearing about 25 lines of very fine ciliation 
(widest portion). 
Funicle joints quadrate or a little wider than long; club 1 plainly not half 
the length of club 2. grotiusi Girault. 
Yellow species, the -wings infuscated. 
Dull honey yellow with obscure transverse stripes across abdomen; both funicle joints 
transverse and equal ; an indefinite fuscous patch below the stigmal vein ; cilia 
proximad of hairless line arranged in about 10 lines. fuscipennis Howard. 
Genus PERISSOPTERUS Howard. 
Fore wings with an oblique hairless line from stigmal vein; antennas 6-jointed with two 
small funicle joints; ovipositor plainly exserted; fore wings with an irregular pattern of spots 
or lines; postscutellnm acutely triangular. 
A species of this genus was reared in large numbers at Nelson (Cairns), Queensland, in 
December, 1911, from a Cltionaspis on the foliage of a native forest tree, but the material 
unfortunately was badly preserved, and 1 could not make out with certainty its complicated 
wing pattern. It is probably a native species and unknown to science. 
Later better specimens were found and I am now able to describe the species. The 
specimens were of the same lot. 
1. PE RISSOPTERUS INEXPLICABILIS new species. 
Female: — Length, 0.60 mm. 
Brown with a (or several) row r of round dots down each margin of abdomen; legs 
white, conspicuously spotted and banded with black; fore wings with a reticulate pattern of 
fuscous as in mexicanus Howard and pulchellus Howard, but there is a less number of inclosed 
hyaline areas and the arrangement is different; proximad of hairless line, a small patch of 
coarser dise-al cilia against origin of stigmal vein and the larger patch incloses a conic-ovate 
hyaline space; midway between the apex of venation and apex of wing a little cephalad of 
centre there are two large rounded inclosed clear spaces, their bounding fuscous ciliation forming 
a complete figure 8; the whole apical margin of the wing is dear, none of the fuscous bands 
reaching it; femora with four unequal dusky spots, the tibia) with two (the hind tibiae with 
three) encircling bands, the distal two on hind tibiae adjacent, apparently confluent in one 
aspect Proximal and distal tarsal joints in all legs dusky black. Scape -white at tip and 
beneath; third funicle joint white toward tip, narrowing there; antennae black. 
Male : — Not known. 
Habitat: Nelson (Cairns), Queensland. 
Type: No. Hy 1720, Queensland Museum, two females on a slide with the types of Casca

2. PERISSOPTERUS CAPILLATUS Howard. 
Howard, 1907, p. 87. 
The principal characteristics of this species are taken from its original description: 
Head uniformly orange yellow; mesonotum lemon yellow; metanotum darker; abdomen marked 
with alternating transverse bands of light yellow and honey yellow r ; antennas light yellowish; 
legs pallid, femora dusky at tip; middle and hind tibiae dusky at tips, aud with two other
