Mr. F. P. Pascoe on some new Australian Longicornia. 373 
of the antennal joints, as well as the number having spines, will pro- 
bably be found to vary, should other species be discovered. At least, 
such is the case in Phacodes. The type is 
Thersalus bispinus. 
Phacodes bispinus, Pascoe, Trans. Ent. Soc. ser. 3, i. p. 562,| 
- Phacodes elusus. 
P. fuscescens ; prothorace irregulariter griseo pubescente, punctis dispersis 
annulatis; elytris pubescentibus, maculis glabris adspersis, apice singulis 
rotundatis. 
Hab, South Australia (Mr. Odewahn). 
Brownish, paler on the elytra; head and prothorax dull brown, with 
a short, greyish, irregular pile, the latter slightly transverse, much 
broader than the head, the sides rounded ; the disk without any tubercles 
or elevations, but under a strong lens it is seen to be thickly punctured, 
and each puncture surrounded by a narrow, elevated margin ; scutellum 
nearly circular; elytra rather elongate, closely punctured, the spaces 
between the punctures rising into short, indefinite, transversely undu- 
lating lines, the pubescence irregular, with small glabrous spots, apex 
of each elytron rounded; body beneath and legs with much closer 
pubescence, the former with numerous glabrous points; antennz about 
as long as the body, the third and fourth joints equal, or nearly so, and 
unarmed, Length 10 lines. 
Resembles a small narrow example of P. obscurus, Fab. ; but, 
besides the absence of tubercles on the prothorax, puncturing, &c., 
it will be distinguished by the fourth antennal joint scarcely shorter 
than the third, and the absence of the apical spine. These two cha- 
racters, indeed, might be considered sufficient to justify their generic 
separation, were it not that the two species have precisely the same 
habit. 
Phacodes fuscus. 
P. fuscus, sparse setulosus; prothorace crebre reticulato-punctato ; elytris 
setulosis, vix pubescentibus, apice singuli rotundatis. 
Hab, South Australia (Mr. Odewahn). 
Resembles the last in most of its characters, but is scarcely pubescent ; 
and the prothorax is so closely and deeply punctured that the intervals 
have a completely reticulated appearance, very different from P. elusus. 
Length 10 lines. 
Phacodes distinctus. 
P. fusco-brunneus; prothorace glabro, creberrime punctato; elytris di- 
sperse pubescentibus, fulvo biplagiatis, apice rotundatis. 
Hab. South Australia (Mr. Bathurst). 
Dark reddish brown; head rugose, with scattered greyish hairs;
