MR. F. P. PASCOE ON THE LONaiCOENIA OF AUSTRALIA. 93 



It will be seen from the diagnosis tliat the form of the apices 

 of the elytra is very different from that of U. triangularis, to 

 which it bears a close resemblance. 



Uracanthus miniattts. 



U. supra ferrugineus, pube miniata tectus ; abdomine, antennis pedibus- 

 que nigris ; apicibus elytrorum rotundatis. 



Hab. Western AustraHa. 



Ferruginous above, covered with a coarse yellowish-red pubescence ; 

 abdomen, legs, and antennae black, with a very sbght pale-greyish 

 pubescence; sterna reddish ; head slightly punctured; clypeus strongly 

 marked ; posterior half of the prothorax much broader than the an- 

 terior, elytra a little incurved at the sides, the apices rounded ; eyes 

 smaller than in other species of the genus, and considerably less ap- 

 proximate beneath ; antennae not reaching to the end of the elytra ; 

 mandibles and palpi brownish, the former irregularly punctured. 

 Length 8 lines. 



A slightly aberrant form of the genus, owing to its colour and 

 smaller eyes. The specimen in the British Museum, the only one 

 I have seen, is probably a female. 



OmOPHCENA TiElSriATA. 



O. nigra, confertim punctata ; elytris singulis lineis duabus subelevatis 

 et vitta aurantiaca ornatis ; antennis nigris, articulis 4'°, 6'°, et 6*° di- 

 midio basali, albis. 



Hab. . 



Black, slightly nitid, with numerous slender erect hairs on the upper 

 parts and legs ; a bright orange stripe running from the shoulder to 

 the apex ; head and prothorax closely punctured, the latter broader 

 than the head, narrower at the base, the sides somewhat parallel, 

 the disk with three almost obsolete tubercles ; elytra scarcely broader 

 than the prothorax, the sides parallel, two indistinct elevated lines 

 on each ; body beneath black, the abdomen brownish, shining ; legs 

 and antennae black, the fourth, fifth, and sixth joints of the latter 

 with their basal halves white. Length 4 lines. 



Omophoena is distinguished from its allies by its 10-jointed an- 

 tennae. The type (0. Krueslerce) differs from the present more 

 particularly in the form of its* prothorax, which is narrower, and 

 more rounded at the sides, and in the absence of any raised lines 

 on the elytra. In the British Museum. 



SiDIS. 



Caput triangulare. Oculi magni, reniformes, supra distantes. Antenna 

 breves, basi remotse, scapo basin versus attenuato et curvato, articulo
