[Long. 5 J, lat. f^ line (vix). 



As in 0. humeralis, Saund., the head, the prothorax, the basal 

 five or six joints of the antennae, and the legs, are clothed with 

 long hairs. The front part of the elytra also is hairy. The extreme 

 apex of the antennae is obscurely yellow. Rather more than the 

 basal I of the elytra is bright blue, whence this colour gradually 

 fades into dull ferruginous with a slight metallic tone. 



Western Australia ; taken by E. Meyrick, Esq. 



Amphirhoe sloanei, sp.nov. 



Picea ; capite, antennarum basi, prothorace antice, elytris basin 

 versus, pedibusque (femorum clava excepta), rufis ; abdomine 

 nonnullis exemplis rufescenti; elytris intus subtilius, extus fortius, 

 crebre rugulose punctulatis; his apice biapiculatis vittis 2, interna 

 elongata, externa perbrevi, flavo-eburatis ; prothorace quam latiori 

 longiori; tarsorum anticorum articulo basali elongato subparallelo.

This species appears to be mixed in collections with A . decora, 

 Newm., to which it bears much resemblance, and from which it 

 differs as follows : — it is a more slender insect, with the ferruginous 

 parts much brighter, — the head especially (which in decora is 

 piceous behind) being unicolorous and of quite an orange ferru- 

 ginous tone ; the prothorax is more elongate and less swollen on 

 the sides (in decora by measurement it is scarcely longer than its 

 greatest width, in this species decidedly so) ; the inner extremity 

 of the apical truncation of the elytra is obsoletely, the outer 

 distinctly, spinose ; the basal joint of the anterior tarsi in both 

 sexes is much longer than wide and is almost parallel-sided, whereas 

 the same joint in decora is of a triangular shape and is scarcely 

 longer than its width across the apex. 



My specimens of decora were taken near Port Lincoln, — and 

 they are evidently identical with the species figured by Lacordaire
