lepta. C. lepta fFe,sh Abdomen greyish-brown, thorax more whitish. Forewing white, scantily striated greyish- 
brown. A faded greyish-brown spot from the cross-vein obliquely to the costal margin near the apex. Hind¬ 
wing greyish-brown. $ 29 mm. Luzon, Mindanao. 
rufidorsia. C. rufidorsia Hmps. (93 i) is at least very similar to chloratus. Body reddish-brown. Forewing reddish- 
brown in the interior area with dark brown striae. Some irregular dark lines close behind the centre. The 
whole marginal area is lighter. Hindwing dark brown. <$ 34 mm. Sikkim. 
2. Genus: Ciilama Wkr. 
Antennae of long-pectinated to the tips. Palpi very long. Wings shaped similarly as in Cossus. Fore¬ 
wing: veins 2, 3, 4, 5 at almost equal distances. 6 below the upper cell-angle. 7 from near the apex of 
the areole, 8 + 9 from its apex, 10 + 11 from its anterior edge. Hindwing: veins 6 and 7 from the same 
basis. Hind tibiae with 2 pair of spurs. Type: australis Wkr. 
australis. C. australis Wkr. (93 i). Body and forewing greyish-brown, with a violet gloss, with numerous dark 
reticulate lines. One of them in the centre and one before the margin mostly somewhat stronger, besides a 
short longitudinal streak in the cell-end. Hindwing much lighter brown. $ 65 mm. New South Wales, Queens¬ 
land. The larva is flattened, bright pinkish red, 50 mm long, not unlike a Carabid larva. It lives between 
the bark and the wood. 50 specimens may feed in a single tree. A Latin name is not mentioned for the 
tree, it is only called: “red india-rubber tree”. 
catiginosa. C. caliginosa Wkr. (= rhytiphorus Lower). Body dark slate-coloured. Thorax with a black trans¬ 
verse band in front and 2 lateral stripes. Forewing slate-coloured with numerous black transverse striae 
which are edged with white and ochre, forming erect lines. 5 irregular black streaks in the interior half of 
the costal margin extend interruptedly to the inner margin. A Y-shaped mark in the middle of the costal 
margin, extending indistinctly to y 2 of the inner margin . 5 or 6 similar indistinct darker places in the distal 
half of the costal margin. Dark reticulate lines near the anal angle are cut by a black line extending from 
the base to the anal angle. Hindwing greyish-white. 6G —70 mm. South Australia, Victoria. 
cxpressa. C. expressa Lucas. Palpi short. Body grey, with dark brown and black hair. Forewing grey with 
slaty grey and dark grey places and deep black striae. Whitish at the costal margin, the lines and streaks 
in the distal area reticulate. Hindwing from dark grey to black. Similar to caliginosa , but much smaller and 
with stronger lines. 25—40 mm. Brisbane. 
3. Genus: Paraeossus Hmps. 
Palpi not reaching the frons. Antennae of shortly pectinated to the tips. Hind tibiae with two 
pair of spurs. Forewing: veins 3, 4, and 5 equably separated. Vein 6 from the upper cell-angle or below it. 
7 + 10 + 8 + 9 stalked. Hindwing: veins 3 and 4 from the same basis, 5 a little above it, 6 and 7 well 
separated. Type: parva Hmps. 
parva. P. parva Hmps. Vein 6 of forewing from the cell-angle. Body and forewing pale greyish-brown, darker 
on the abdomen above. Forewing with fine dark striae, the interior area reddish-brown. A feeble black 
median line is slightly angled at the median vein, and excurved below it. A short line from the cross-vein to 
the costal margin, then continued inwardly at the median vein, extra-angular at vein 2 and then again 
inwards. The exterior line is more distinct, obliquely outwards, forming an outward angle at vein 4, then 
vertical and undulate to the inner margin, connected at vein 4 with the undulate submarginal line by a bar. 
Hindwing dark brown with darker veins, somewhat diaphanous. <$ 26 mm. Ceylon. 
/ areata. P. furcata Hmps. (93 k). Pale greyish-brown. Forewing with darker striae and red-brown lines. The 
interior one forked, enclosing an elliptic spot in the middle. Median line rather straight, connected in the 
submedian fold with the exterior line by a streak. Exterior line excurved as far as vein 5, bent inward at vein 
4 and connected with the irregular submarginal line at vein 1. Hindwing pale brown. $ 32 mm. Pegu. 
4. Genus: Aretlocossus Fldr. 
Kirby places one Australian species to this genus which has been dealt with in Vol. XIV, p. 543.
