This interesting Australian insect formed a portion of the col- 

 lections made by Peron in the South Seas, and is now in the 

 museum of Mr. Hope, obtained from that of the late M. Gory, 

 and inscribed with the manuscript name which I have adopted, 

 and whicli was, I believe, proposed for it by M. Latrielle. It 

 agrees with L. Menalcas in the form of its very curved mandibles, 

 but its maxillae are not armed with a curved spine ; the mando is 

 straight and acute. How far this character will, however, inter- 

 fere with the sectional arrangement of the family proposed by Dr. 

 Burmeister remains to be determined.

Obs. — Both sexes of this species have the mando of the maxillae 

 furnished with a corneous hook ; the mandibles of the male are 

 very similar to those of Z. Cancroides.
