oculos plana et recte truncata. 2. Long. corp. lin, 25. 
Habitat in Terra Van Diemenii. In Mus. D. W. W. Saunders, F. L. 8. 
Species X.—Mutilla elegans, Westw. (Plate 53, fig. 2.) M. tota cerulea nitida punc- 
tata, cinerascenti-hirta, antennis longis tarsisque nigris, abdomine elongato, segmento 1mo

Expans. alar. lin. 62. 
Habitat in Terra Van Diemenii. D. Ewing. Mus. Brit. et Westw. 
In this species the veins separating the submarginal cells are 
inserted into the marginal cell at nearly equal distances apart ; 
and the first recurrent vein is received by the second submarginal 
cell rather beyond the middle, whilst the second recurrent vein is 
received nearly at the extremity of the third submarginal cell, 
forming nearly a straight line with the extremity of the third sub- 
marginal cell. 
Species XI.— Mutilla abdominalis, Westw. (Plate 53, fig. 1.) M. nigra tenuiter punctata 
hirta, capite scutelloque cinerascenti hirtis, abdomine obscure purpureo tenuissime punc- 
tato pilis albis utrinque ad apicem segmentorum 2di et ultimi; pedibus nigris, tibiarum 
4 posticarum et articulo basali tarsorum albis; alis fuscis, hyalino-variegatis, segmente 
basali abdominis parvo nodum parvum transversum ad basin formanti, 2do magno cam- 
panulato. @. Long, corp. lin. 6. Expans. alar. lin. 11. 
Habitat in Australasia. In Mus. Brit. 
The insertion of the veins in this species is very similar to that 
of the preceding species. 
Species XII.—Mutilla morosa, Westw. (Plate 54, fig. 1.) M. nigra punctata nigro- 
hirta, thorace rugose-punctato, abdomine fascia pilorum alborum ad apicem segmentorum 
Imi et 2di, hoc parum constricto, alis hyalino et fusco variis, apice late fusco. Long. corp. 
lin. 6. Expaus. alar. lin. 94. 
Habitat “Swan River.”? In Mus. Brit. 
Species XIII.—Mutilla concinna, Westw. (Plate 53, fig. 3.) M. capite magno, cyaneo 
punctato antice bicorniculato, thorace parvo nigro oblongo-punctato, lateribus et subtus 
ferrugineis, abdomine magno eneo nitido, sericeo, postice pilis aureis in maculas dispositis 
ornato, antennarum articulo basali mandibulisque (nisi ad apices oblique emarginatos) 
pedibusque ferrugineis. Long. corp. lin. 43. 
Habitat in Terra Van Diemenii. Mus. Newman, Westwood, etc. The trophi do not differ 
in this curious species from those of the rest of the genus. 
Gznus.—PSAMATHA, Shuckard. 
This genus was established by Mr. Shuckard, in the Transactions 
of the Entomological Society of London, for the reception of an 
insect having precisely the habit of a male Mellinus, but remark- 
able as being the only one yet characterized among the Mutillide 
in which the second sub-marginal cell receives both the recurrent 
nervures,* in which respect it also differs from all the species of 
insects of which Thynnus is the typical form, except the genus 
Tachypterus Guérin. Dr. Klug having on this account omitted 
the genus and its supposed female in his beautiful memoir on the 
Thynni, recently published in the Berlin Transactions, I have been
