pectinate hair, two latéral sharply pointed smooth hairs and one médian thick and smooth 

 hair. The paratarsi are small, scarcely longer than wide, very heterodactyle ; the external 

 claw is feather-like and resembles the empodium of Cheletinae\ the internai claw is claw-like 

 with granulate surface; the empodium is claw-like, slenderer and longer than the internai 

 claw, proximally and distally nodded, and distally blunt. 

 Habitat: on a kind of ant.

 n°. 23, p. 223. 



Patria : New Guinea, near the Lake of Jamûr. 

 Found by Messrs. Lorentz and de Beaufort. 



Larva (Fig. 88 — 93). LengtJi of body very variable; length of dorsal shield 304 — 320 y-, 

 of coxal plate 240 — 250 ,«. Colour most probably orange-coloured, or scarlet, for several spéc- 

 imens prepared in spirits contained still a drop of orange-coloured fluid, or oil. Shape in 

 gênerai broad-oval, top forward. Texture of the shields marked with long hexangulars (Fig. 90), 

 like the cells of the epidermis of the Liliaceae; of the legs and rostrum smooth; of the skin 

 between the coxal plates punctured ; of the remaining skin finely wrinkled. 



Dorsal side (Fig. 88). Shield long, with slightly convex sides, suddenly narrower be- 

 hind the second pair of eyes, tapering forward with slightly concave oblique edges, anter- 

 iorly rounded ; posteriorly rounded. Its latéral margin lies under the skin. Eyes four in number, 

 lying underneath the wrinkled skin, not prominent ; the anterior ones larger with distinct 

 lense; the posterior ones smaller, dull. Hairs: in the anterior triangular portion of the shield 

 3 pairs of hairs, one pair on a line with the anterior eyes; one pair on a line which goes 

 exactly between the anterior and posterior eyes; one pair a little behind the posterior eyes. 

 On the weak skin two pairs of hairs; one pair a little behind the foremost third of the shield ; 

 the other pair a little behind the second third of the shield. 



Ventral side (Fig. 89). Coxal shields fused together on each side to one plate, leaving, 

 however, distinct démarcations. Coxa I long and narrow; coxa II longer and narrow; coxa 

 III much larger than coxa I and II together, internally straight, posteriorly and externally 

 rounded. Each large plate, formed by the fusion of the three coxae, internally straight, anter- 

 iorly excavate obliquely to the side of the rostrum ; externally and posteriorly rounded ; so 

 that when the two plates and the rostrum are brought together and touch one another (which 

 must be the case in newly born larvae) thèse three parts from together an oval, top forward. 

 Urtrachee small, round, behind trochanter I. Anus in the middle of the belly, between the 

 coxal plates and the posterior edge of the abdomen. (In newly born larvae the anus most 

 probably is situated between the two posterior angles of the coxal plates. Hairs: in the 

 middle of the posterior (oblique) margin of the coxal plate I a hair; near the anterior internai 

 corner of coxal plate III a hair; a pair of hairs on a line before the anus; 4 hairs posteriorly 

 of which the internai pair as long as coxal plate III.
