354 Mr. A. White on Telocera Wollastoni. 



Callidia, the antennae are by no means conspicuous for length. 

 Again, if we restrict ourselves to Australian Longicorns, how 

 strange are the curiously lamellated antennae of the beautiful 

 genus Petalodes of Newman, of which a second species exists in 

 the Museum Collection, which I have named P. plagiatus*, from 

 the long pale-yellow smooth spot so conspicuous on each ely- 

 tron from the middle to near the tip, — the basal half of the elytra 

 being strongly punctured, a yellow punctured patch before the 

 smooth patch, and only separated from it by a narrow stripe, of 

 the general pale brown of the elytra ! How different must be the 

 economy of this insect, so far as the male uses these finely lamel- 

 lated antennae, from the economy of the Scolecobrotus Westwoodii 

 of Hope, whose antennae have their fore-edges strangely ser- 

 rated ! and yet the insects are not very distantly related. Then, 

 again, the dilated antennae giving Telocera somewhat of a Lan- 

 guria appearance, or of a Triplet w, must have a purpose and use 

 different from the simple linear antennae of the Callidia and 

 Pytheus, to which it is allied. 



The genus which I describe under the name of Telocera is 

 allied to Pytheus of Newman, one species of which only is known, 

 the Pytheus jugosus from Sydney. As the genus Brachytria, 

 close to Pytheus, varies in its coloration, and apparently in the 

 different sexes, I thought that Pytheus and Telocera might pos- 

 sibly be sexes of one genus, and even of the same species, in that 

 country of anomalies in structure, where the female of Disticho- 

 cera y for instance, is totally unlike her partner. It would be 

 very rash, in our present state of knowledge, to regard Telocera 

 as such. There were three specimens of this pretty beetle in the 

 collection bought by Mr. Stevens. One of these only I have 

 seen. It is in the British Museum ; the other belongs to Mr. 

 Pascoe; while Mr. Thompson of Paris procured the third for 

 his noble collection, during his late passage through London, 

 on his route from America to the French capital. The figure, 

 carefully drawn on the block by Mr. Ford, but much magnified, 

 shows its curious form.

 usual small, somewhat globular at apex; third and fourth
