310 Mr. F. P. Pascoe on some new Genera of 



tially dissimilar. In the case of the eyes, the upper lobe entirely 

 disappears; and it is worthy of remark that in the subfamily* 

 to which this insect belongs there has as yet been found no in- 

 termediate form of eye : it is either normal or at once reduced 

 to a single, and always lower, lobe. 



Demomisis filum. 



D. rufo-brunnea J elytris costulatis, interspatiis punctis seriebus 



duabus instructis. 



Hab. Western Australia (Champion Bay). 



Reddish brown, bases of the joints of the antennae and tibiae 

 paler; head finely and sparsely punctured, a groove on each 

 side between the eye and the mouth ; prothorax finely corru- 

 gated transversely ; scutellum large, triangular ; elytra with four 

 elevated lines on each, the second and fourth united near the 

 apex, the intervals with two rows of coarse punctures at the 

 base, but uniting to form a single row posteriorly ; body beneath 

 dark brown. Length 3 lines. 



ZORION. 



Caput pone oculos sensim attenuatum ; oculi parvi, profunde emar- 



ginati. ^ 



Prothorax basi apiceque constrictus, postice tenuior. 

 Femora abrupte clavata. 



Head somewhat quadrate, transverse in front ; the antennary 

 tubers prominent, rising gradually from each side of the mesial 

 line. Eyes small, deeply emarginate, finely granulate. Antennae 

 as long as the body, linear, distant at the base ; the scape cylin- 

 drical and longer than any one of the other joints ; the third, 

 fourth, and fifth nearly equal, the rest gradually shorter. Pro- 

 thorax narrower than the head, deeply constricted at the base 

 and apex, the posterior very much narrower than the anterior 

 portion, the sides angulated at the middle. Elytra short, obo- 

 vate. Legs increasing in length from the anterior to the poste- 

 rior; femora abruptly clavate; tibiae slender; tarsi of nearly 

 equal length, not dilated. 



The type of this genus is Callidium minutumj Fab. (Syst. Ent. 

 p. 192, 1775). Prof. Westwood has since described a second 

 species, under the name of Obrium guttigerum (Arc. Ent. ii. p. 25). 



* Having recently obtained a male example of Diotima allied to, or 

 possibly identical with, D. lindulata, and belonging to the same subfamily, 

 I may mention here that the antennai are much longer than the body, and 

 nearly twice as long as in the female, and that they are, moreover, twelve- 

 jointed. 1 have also a female specimen, from Clarence River, scarcely 

 more than half the length of the specimen described by me, and which 

 seems by its characters to belong to yet another species of the genus.
