Loc. Ternate and Galela in Halmahera. 
Recorded by Thorell from Ternate. 
Gasteracantha bruijnii Thorell. 
Pl. XXV, fig. 4. 
Ann. Mus. Genova XVII, p. 21 (1881). 
Of this species, recorded originally from Ternate, Dr. Kükenthal obtained specimens 
from Ternate and Batjan. 
Gasteracantha tondanae sp. n. 
DL, OO, ilez, 8 
Colour: Carapace and mandibles black; legs black, with yellow rings at the base of the 
tibia, protarsus and tarsus, on the lower side of the legs there is also a yellow spot on the 
coxa and on the base of the femur; palpi annulate like the legs; maxillae distally flavous; 
sternum with a large anterior flavous spot; lower side of abdomen black with small yellow 
spots; upper side yellow, with black spines and sigilla and a narrow black rim. 
Abdomen transversely oblong, more than twice as wide as long; the anterior border 
nearly transverse, a little advanced in the middle, sinuous, lateral border between the spines 
nearly straight, directed obliquely backwards; posterior border external to the posterior spines 
transversely convex ; spines short, the anterior lateral a little smaller than the posterior lateral 
and directed obliquely outwards and forwards, the posterior lateral direeted obliquely out- 
wards and backwards; the posterior spines a good deal longer than the posterior laterals. 
Measurements in millimetres. Length of abdomen 5.5, width 13.3. 
Loc. Tondano in Celebes (C. Hose); Minahassa (W. Kükenthal). 
This species is very nearly allied to @. dutleri Thorell from Kandari (Ann. Mus. 
Genova X, p. 350, 1877); but according to one of Thorell’s examples in the British Museum, 
may be recognised by its wider abdomen and much shorter spines. Perhaps it may prove 
to be a sub-species of that form. It is also without doubt nearly related to @. ewrygaster 
Thorell from Gorontalo in Celebes (Ann. Mus. Genova XXVIN, p. 25, 1890; see also van 
Hasselt, Tijdschr. Ent. XXII, p. 217, 1879); but according to the description of the latter 
may be recognised by having the abdomen distinetly less than three times as wide as long 
instead of more, van Hasselt’s words being „abdominis seuto....paralleloegrammum 
transversum fereregulare, plus quam triplo latius quam longius formante.“
