Type, Macrolema vittata, Baly. 



This striking genus stands in close proximity to Brachydactyla, 

 Lac, agreeing in having a distinct prosternum and in not possessing 

 conical anterior coxae, but differing in the third and fourth joints of 

 the tarsi being formed in accordance with the ordinary type of the 

 family, and in the anterior coxae being transverse instead of hemi- 

 spherical. From all the remaining genera, the transverse anterior 

 coxae and (Megascelis and the first section of Crioceris excepted) 

 the possession of a prosternum separate it. 



The beautiful insect on which the genus is founded has been 

 recently sent by Mr. Diggles from Dawson's Biver, a new settle- 

 ment in the northern part of Queensland, Australia.
