 the body a series of 29 — 31 large projecting 

 tubercles (fig. 2), each bearing at the extremity 

 several short stiff spines, and at the sides a 

 few fine hairs and small circular spinnerets. 

 Anal lobes, a little larger than those at the 

 margin, have a single long hair at the apex, 

 and a few short spines. Antennae (fig. 3) of 

 8 joints ; 3 and 8 longest ; 1 and 2 a little 

 shorter and widest ; 4, 5, 6, and 7, shortest 

 and equal ; all with a few fine short hairs 

 Mentum biarticulate, has many fine hairs at 

 the apes. Legs stout, shorter than antennae ; 

 digitules very slender. Anal ring with six very long hairs. Dermis above with four 

 large eye-like glands : two above the rostrum, and two on the penultimate segment. 



Long., 150 — 2 mm. 



Hah. : Madagascar, in iiests of Crematogaster ScheiiJci, For. This 

 most remarkable insect clearly belongs to the DactyJopiidoe, and is 

 unique in having the large marginal tubercles. 



Dacttlopius hirsutus, n. sp. 



? adult short-ovate. Antennae (fig. 1) of 8 joints ; 4, 5, and 6 shortest, and 

 in length equal ; 8 much the longest, and slightly fusiform. Mentum biarticulate, 

 long, conical, with three or four long hairs at apex, and one or two at the sides ; 

 unexpanded filaments a little longer than mentum. 

 Legs short, stout, about one-third longer than antennae, 

 with a few short isolated hairs ; digitules of the tarsi 

 simple ; those of the claw more dilated and stouter. 

 Anal ring with six long hairs. Anal lobes minute, each 

 with a number of hairs of the same length as those of 

 the anal ring ; the usual long hairs are wanting in all 

 the specimens examined. There are two large eye-like 

 glands just behind the antennae, and two on the last abdo- 

 minal segment. Dermis above thickly set with long fine 

 hairs. Long., 2 — 2"50 mm. 



? second stage short-ovate, attenuated beln'nd. Antennre of 6 joints, of which 

 the last is much the longest and widest. Mentum biarticulate. Anal lobes normal ; 

 each with a single long hair, and several others almost as long. Anal ring of six 

 hairs. Dermis above with fewer, but longer, hairs than those in the adult ; those at 

 the margin still longer, and almost forming a fringe. Dorsal glands as in the adult. 

 Larva with very long hairs at margin and on the dermis above ; those of the 

 latter forming three broad longitudinal lines.

 matogaster sp., and Sima nigra, J.
