interstice, one level with it on tlie fifth, and the other on the 

 third, slightly beyond the others; the latter one is sometimes 

 entirely composed of whitish scales, and sometimes of sooty 

 and whitish ones, and the striae at its sides are deflected out 

 of straight lines by the slight swelling on which it is 

 supported. 



A specimen from Wollongong differs in being very small 

 (2 J mm.) and with the elytral scales mostly sooty, but with 

 the pale fascia distinct. Another, of the same size, from 

 Cairns, has the scales on the upper-surface of an uniform pale 

 slaty-grey, with a sooty spot on each side. On all the speci- 

 mens, however, the postmedian sinuation of the second and 

 third striae is distinct, 



Meniomorpha inconstans, Lea. 

 Some specimens, from the Northern Territory, have 

 whitish scales occupying most of the upper-surface. On one 

 specimen the dark scales occupy a subquadrate medio-basal 

 patch on the prothorax, a patch on each elytron at the base 

 between scutellum and shoulder, and an irregular postmedian 

 band, the band irregularly dilated on suture both in front 

 and behind. Queensland specimens usually have the white* 

 occupying much less of the surface — usually a strongly curved 

 mark on each side of elytra at the base, the two meeting at 

 the scutellum, and an irregular patch on each side of apex. 

 On the prothorax the only white markings are remnants (at 

 base and apex) of a median line. 



Tychreus. 

 In the diagnosis of this genus, ^23) based largely on the 

 typical species fcamelus ), the eyes were described as finely 

 faceted, the rostrum thin, and the mesosternal receptacle 

 almost open ; and these characters apply to most species of the 

 genus. But some of the smaller ones have the eyes moderately 

 or rather coarsely faceted, and with the rostrum of the males 

 rather wide. In three species also (sellatus, incanns, and 

 nigronotatus) the receptacle, although its emargination is 

 U-shaped, has the base considerably wider than the sides, 

 although not to such an extent as is usual in PsPvrJometyrus 

 and M etyrus S'^'^^ 



Tychreus eeversus, Lea. 



The facets of the eyes of this species, although hardly 

 coarse, are still larger than in most species of the genus. A 

 small (3 mm.) male from Cairns has a conspicuous dark fascia

(24) This to a certain extent is sexual; as in T. sellatus, the base 

 is wider in the male than female.
