the Australian Longicornia. 543 



the apical portion, which is luteous, partially spotted with grey, and 

 having at the side a large luteous patch, with one larger nearly 

 white spot and two or three smaller spots marked on it ; body 

 beneath glossy luteous, the pectus somewhat pubescent, with a 

 greyish patch enclosing a single shining spot on each side of the 

 four basal abdominal segments ; legs sparsely pilose. 



Length 4 — 5 lines. 



This species has a small, abrupt tooth at the side of its 

 prothorax, which, however, has otherwise quite the character 

 of those in which the disc is not tuberculate. It also differs in the 

 rounded apex, and in the absence of the elevated line which runs 

 into the outermost of the two spines, which always occurs when 

 the apex is bispinous. 



Genus Oricopis. 

 Caput imraersum, fronte quadrata. Oculi emarginati. An- 

 tennce mediocres, subapproximatse, articulo basali subturbi- 

 nato, tertio quarto breviori, cseteris multo brevioribus. 

 Prothorax elevatus, bituberosus, lateribus dentatus. Elytra 

 tuberculifera. Pedes mediocres, femoribus clavatis. Pro- 

 sternum simplex. Mesosternum antice productum. Corpus 

 ovatum, rugosum. 

 It is with some hesitation that I have separated the species de- 

 scribed below from Zygocera, but there is such an amount of 

 variation in its aspect and characters as would, I believe, preclude 

 any one from searching for it in that genus. The characters, 

 however, considering how variable they are in Zygocera itself, are 

 but slight ; the form of the basal joint of the antennae, and the 

 difference in the length of the third as compared with the fourth 

 joint (in direct opposition to the true Zygocene), being certainly 

 the principal. 



1. Oricopis umhrosus. (PI. XXIII. fig. 2.) 

 O. rufo-fusca, pube pallidiori tecta ; prothoracis disco tuberibus 

 bifidis remotis ; elytris tuberculorum lineis duabus obliquis 

 instructis. 

 Port Denison. 



Dark chocolate brown, covered, except on the tubercles, with a 

 paler pubescence ; antennae scarcely longer than the body, slightly 

 ciliated beneath, the basal joint short, swelling out towards the 

 apex, the third much shorter than the fourth joint, each of the re- 

 mainder not half the length of the fourth ; prothorax rather broader
