yidion they are scarcely longer than the body, the basal joint being 

 shorter than the third and foiirth, which are nearly equal, and the 

 remainder rapidly diminishing. The habit, however, is so similar 

 to Cercegidion, and is in itself so remarkable, that it would be natur- 

 ally inferred that they were not only nearly allied — as in tn^th they 

 are — but that they were also natives of the same regions. This 

 supposition is, however, doubtful, — Major Parry, to whom this, I be- 

 lieve, unique Longicorn belongs, having a note to the eiFect that it 

 was taken from a box of Mexican insects. Notwithstanding, I can- 

 not help thinking that, Uke Oercegidion, it is a native of Australia, 



EchtJiistatus spinosus. (PI. XYII. fig. 8.) 



E. fusco-piceiis, sparse pilosus ; prothorace disco subqiiinquespinoso. 



Hah. Australia? 



Dark pitchy brown, roughly tuberculate above the interstices, with 

 small patches of short fulvous hairs ; head with a V-shaped impression 

 above the epistome ; prothorax wider than long, the posterior margin 

 naiTowest, the side with a strong median spine, surrounded with tuber- 

 cles at its base, the disk with short spines, three of which only are at 

 all prominent, two anterior and one posterior, and behind each of the 

 anterior ones two smaller tubercles ; scutelliun quadrate-cordate, con- 

 vex, hairy ; elytra short, broader than the prothorax at its base, pro- 

 minent at the shoulder, thence sHghtly dilating to one-third its length, 

 and gradually rising above into a large somewhat cvu-ved spine, then 

 narrowing rapidly to the apex, which is truncate, with the external 

 angle pointed; legs slightly pubescent, the thighs pitchy, tibife oh- 

 scm-ely ringed with white, tarsi bro^^^l ; antennte twice as long as the 

 body ; beneath pitchy, with a few dull fulvous hairs. Length 6 lines.

Serixia ornata. (PI. XYII. fig. 9.)

 Ilab. Moluccas (Batchian). 



Rather broad ; head reddish testaceous, sparingly pubescent ; eyes 

 and mandibles black ; prothorax greyish brown, the sides varied with 

 rufous ; scutellmn transverse ; elytra remotely seriate-punctate, pale

 middle and towards the side, pure white ; antennae brownish, the third 

 and fourth joints pale at the base; body beneath and legs pale rufous 

 testaceous. Length 4 lines.
