semiopaque, their epipleurae continued below the middle, below

 the posterior ones entirely of that colour with a metallic blue

 apex, with a long spine, tarsi iiavous, the metatarsus of the 

 posterior legs rather lunger than the following joints together; 

 presternum narrowed between the coxae, the anterior coxa] 

 cavities open. 



Hub. Da Dime al Bass Narok, August- Septemb. 1896. Many 

 specimens. 



The structure of the anterior portion of the head in this species 

 is very peculiar and resembles somewhat that of Loxoprosopus 

 amongst the bladder clawed Hulticinae also the Galerucid genus 

 Pseudocrania. Nothing of the kind is known to me amongst the 

 other members of the genus Phyllotreta and it is probable that 

 the species will have to be placed in another genus if other 

 similarly structured should turn up, in general appearance how- 

 ever and in other respects the insect agrees with Phyllotreta.
