Described from a small colony (collected by A. M. Lea) in the 
South Australian Museum collection. The Victorian specimens (col- 
lected by C. Oke, July, 1924, and the New South Wales specimens 
collected by 4V. W. hToggatt, 30.10.24) are almost certainly correctly 
referred to this species. 
Affinities. — The imago appears to be most closely allied to 
M. parviceps Mjob., from which species it is differentiated by its 
smaller and less prominent eyes, markedly less hairy head, thorax 
and abdomen, smaller and paler wings and entirely different Aving 
micrasters (cf. Figs. 185 and 187). The soldiers of these two species 
have not been compared, but Mjoberg s figure indicates a marked 
difference in the shape of the mandibles. The (hieensland species, 
moreover, has Id-jointed antennae (13-jointed in all other Australian 
species). 
Types (imago, soldier and worker) m the South Australian 
Museum. 
Microcerotermes nervosus, n. sp. 
Plate 111., figs. 77-81 ; Plate VI., fig. 188 ; Plate IX., fig. 189 ; 
Plate VIL, fig. 218. 
Imago. 
Colour. — Chestnut, head a little darker than pronotnm and 
abdomen ; postclypeus tawny olive ; antennae, mouth parts and 
legs clay colour pleura and sternites suffused Avith broAvn ; AAungs 
light fuscous (as in M. lead). 
Very similar to M. parciceps Mjob. in colour, &c., but smaller 
and lighter coloured ; eyes as in M. parviceps, i.e., small, circular 
(O' 204 X 0'204), rather prominent. O' 085 from loAA^er margin of 
head • ocelli as in M. parviceps, very small, AAudely separated from 
the eyes, i.e., by a space equal to their long diameter. Antennae 
(Fig. 77) 14-jointed, the joints short and AAude, the 14th as Avide 
as 13th.
