3. Paniscus ( productus, Brullé?). {Fam. Ophionoide.] (Plate CLXXl 
Fig. 4.) This is a large yellowish-brown clear-winged insect, having the bm") 
body, that is usually held in an arched position, compressed from side to side am 
widened towards its extremity. It measures nearly 1 inch in length, and ha” 
wing expansion of 1} inches. Unlike the first-mentioned ichneumon, the * | 
in this are much alike. However, the female’ has a short ovipositor that 18 ™} 
however, always exserted. It also differs from it insomuch as the Paniscus 8 | 
is not an internal feeder, although when the caterpillar transforms in al 
chrysalis it becomes enclosed therein, though covered subsequently by its, 
special cocoon. It also has a comparatively slow flight, and does not “) 
hither and thither when on the wing, and in alighting it seems to do 80 wy 
some hesitation. In attacking a caterpillar it fastens its dark-coloured eggs 
the surface near the head. These eggs are pedunculated or stalked, an¢* 
attached by these stalks being inserted through and beneath the skin of fol 
victim, this being in the first instance punctured by the parent ichneumo?” | 
the purpose. In feeding, the ichneumon grub does not wholly leave the eff 
shell whence it has emanated, and ultimately this remains fixed to it at one &} 
Only a single ichneumon grub appears to mature in each chrysalis. f | 
brown ichneumons were of very common occurrence amongst the Leucania 
pillars met with on the Darling Downs and elsewhere. 4 
Brullé (Lepelletier de Saint Fargeau’s ‘‘ Histoiré naturelle des Inscctes Hymenoptéres, Wal 
156) described, in 1846, an Australian species of Paniscus, but it does not appear that the P ot 
insect is identical with the one noticed by him. The following technical description will se’ 
distinguish the latter :— joe | 
Female.—Y ellowish brown, spot on vertex including ocelli, scabbard of ovipositor and fine! 
of feet black ; posterior orbital band yellowish ; legs passing outwardly to pale testaceous; | 
punctured and for the most part clothed with appressed pale-colonred pubescence, a few tort 
hairs on fore-border of clypeus. Head, depression containing antennary fossie not divided. 
scutellum with disc bounded by straight posteriorly approaching keels ; metathorax transy inh 
wrinkled, without distinct surface areas, fore-border-roundly excavated, the excavation pat 
bounded vy aridge. Abdomen, 1st joint with spiracles long before middle; ovipositor coma 
tively well developed, measuring when exserted nearly as long as first body segment; sal | 
divisions of scabbard curved upwards at origin. Wings with dark-brown veins and brown 1 
yellow stigma, areola present, 2nd recurrent (discoido-cubital transverse) continuous wit : 
cubital transverse, veins interrupted by—usually oval—clear glabrous spaces having the fo lore 
disposition, one in the middle of 1st abscissa (present) of cubital, one in the outer cubital trans¥" | 
two in the 2nd recurrent (discoido-cubital), and one in the discoidal—between origin ot nn 
discoidal and posterior margin. Claws with comb-like teeth—as in other Ophionoidie. F 
length, 20 mm.; expanse wings, 17 mm.; hind legs, 20 mm. : she 
Male.—Smaller, with abdomen more slender, and less wide at extremity. ‘The face i8 oi 
yellow, or much paler coloured than remainder of body ; last abdominal segment represente™ 
two oblong valves instead of a single sheathing scale. | 
4, Apanteles ruficrus, Haliday. (Braconide.] (Plate CLX X1V., Figs. 5,50) | 
This is a minute insect, measuring about 1+ lines long, with a wing expansiO™ 
2% lines. It is black in colour, with pale yellowish brown legs (the first j0!"4,) 
the hindmost pair being black), and four clear wings. It is best known troll) 
cocoons, that are small, white, oblong bodies measuring each about 2 i: nl
