than wide ; femur 1-6 times as wide as tibia. Tibial spur on legs 1 to 11. 

 Tergites (fig. 9) with anterior and posterior angles all rounded ; a slight 

 posterior emargination is evident on the 8th tergite, increasing in depth 

 in posterior segments. 



Length 9 mm. 



Log. — Riccarton, Christchurch (G-. A.). 



Xote. — I have identified the specimens included under this name on 

 the colour alone. The type specimen appears to have been lost, and the 

 character used by Newport to define the species- — i.e., the dentition of the 

 prosternum — is common to many species of the genus, if, indeed, it be not 

 a generic character. Newport examined a preserved specimen when he 

 described L. emarginatus, and the specimens here included under this name 

 were the only preserved ones in my collection which retained the ferru- 

 ginous colour. The determination is as unsatisfactory as can be, and can 

 only be regarded as a compromise until the type is found or the matter is 

 otherwise settled.
