Black ; a transverse band on each side of the first and third ab¬ 
dominal segments, a small spot on each side of the second, a triangu¬ 
lar spot at the apex of the first ventral segment and a small spot on 
each side of the front above the base of the antennae yellow ; the flagel¬ 
lum and the base of the mandibles fuscous 
Length 16 mm. 
Hab. Mafor, Dutch New Guinea (Fruhstorfer). 
Type in Hungarian National Museum. 
Allied to T. serriger Sharp. It may possibly prova to be the female 
of T. olivaceus Turn, which belongs to the same group. 
Other species from New Guinea in the collection are : 
1. Tachynomyia ^cornata . Sm. Jonrn. Proc. Linn. Soc. Zool. VII. p. 27. (1863) cf 
Sattelberg, Hnon Golf (Biró). 
2. Thynnus (Aeolothynnus) abductor Sm. Proc. Linn. Soc. Zool. VIII. p. 78. 
(1864) c? . FriedrichAVilhehnshafen (Biró); Erima, Astrolabe Bay (Biró). 
3. Thynnus (Aeolothynnus) laevissimus Sm. Proc. Linn. Soc. Zool. VITL 
p. 77. (1864) $. Erima, Astrolabe Bay (Biró). Probably the female of 
abductor . 
4. Thynnus olivaceus Turn. Proc. Linn. Soc. N. S. W. XXXIII. p. 251. 
(1908) cf. Boon (Fruhstorfer). 
The yellow markings on the thorax and abdomen are larger and more 
numerous than in the type, especially on the mesothorax and abdomen. 
Thynnidæ will probably prove to be few in number in New Guinea, 
though it is possible they may be more numerous in the mountains. 
The absence of Rhagigaster is remarkable considering that the genus 
is as well represented in tropical Queensland as in any other part of 
Australia. 
Thynnus celebensis sp. nov. 
cT. Clypeus pointed at the base and touching the apex of the 
interantennal prominence, slightly depressed to the apex and closely 
longitudinally rugose striate, the apical margin very broadly truncated 
with slightly prominent angles. Antennæ a little longer than the thorax, 
of even thickness throughout, inserted further from each other than 
from the eyes; the interantennal prominence smooth and shining, divi¬ 
ded almost to the apex by a broad punctured sulcus which does not 
extend to the anterior ocellus. Head very closely punctured, the poste¬ 
rior ocelli nearer to each other than to the eyes. Pronotum as broad 
as the head, the anterior margin very slightly raised ; the whole thorax 
and abdomen rather finely and very closely punctured ; the mesonotum 
with the usual two longitudinal sulci on each side. Scutellum large,
