the Australian Longicornia, 531 



versim plicato ; elytrissubtrigonatis, apice sinuato-truncatis, 

 lateribus maculis duabus magnis albo-pubescentibus. 

 Interior of Northern Australia. 



Black, slightly nitid, with a few exceedingly delicate scattered 

 white hairs ; head remotely punctured, with a deeply impressed 

 line in front ; lip, epistome and palpi dark ferruginous ; antennae 

 strongly fimbriated beneath ; prothorax full and rounded at the 

 sides, somewhat abruptly constricted in front, the disc transversely 

 impressed with waved lines, two slight tubercles in the middle 

 and another strongly marked at the side anteriorly ; scutellum 

 scutifoi'm ; elytra subtrigonate, the shoulders produced, two very 

 slightly marked ridges at the base, where it is also more coarsely 

 punctured, the apex sinuately truncate, the side with two very- 

 large pure white hairy patches of irregular figure ; body beneath 

 black, shining, each abdominal segment bordered with closely set 

 white hairs ; legs black, subnitid, anterior coxae in the male with 

 a short incurved spine. 



Length 14 lines. 



A noble and very distinct species, approaching in coloration 

 Rhytiphora cretata, Pasc. Rhytiphora, Newm., may be dis-

 form, more transverse prothorax with nearly parallel sides, and 

 larger head, especially manifested in the strongly developed vertex, 

 which has the effect of throwing the eyes far below the level 

 of the upper line of the prothorax. Symphyletes is masculine 

 (Ivfi^vXirrjQ) and not feminine, as Mr. Newman and others make it. 



2. Symj)liyletes fulvescens. 



S. fulvescente-pubescens, ochraceo varius ; elytris subcylin- 

 dricis, non tuberculatis, apice emarginatis. 



Port Denison. 



Somewhat narrovir, covered with a short, dense, rich fulvous 

 pile, varied with ochraceous ; head rather broad and convex in 

 front, the eyes small ; antennae slightly ciliated, spotted at the 

 base with ochraceous ; prothorax scarcely narrower anteriorly, 

 the tooth at the side well marked, the disc irregular, with two 

 small tubercles ; scutellum subquadrate ; elytra somewhat cylin- 

 drical, without tubercles, the apex of each slightly emarginate, 

 the ochraceous markings consisting principally of a patch at the 

 side, an oblique band commencing at the suture behind the middle 

 and continued downwards and outwards, another on each side the
