376 Mr. A. M. Lea's Notes on 



coppery reflections. The sides near the shoulders are 

 usually diluted with red ; the scutellum is usually pallid 

 except at the base, but in five specimens it is entirely 

 dark. The five basal joints of antennae are more or less 

 red ; I have never seen them entirely dark as they 

 frequently are in cyanipcnnis. 



The species may be distinguished from cyanijiennis and 

 its varieties by its elytral punctures (not mentioned by 

 Saunders) being much smaller, those on the head more 

 numerous and more or less confluent or strigose, the 

 scutellum more elevated and rounded posteriorly, and the 

 sixth, seventh and eighth joints of antennae of different 

 shape (in cyanipennis they are connected in the middle, in 

 pidchella more towards one side). 



The male was unknown to Saunders, it differs from the 

 female in being smaller and narrower, with longer and 

 thinner antennae, prothorax more deeply impressed, elytra 

 with larger punctures, and the eyes larger and closer 

 together. 



Two males before me have the elytra metallic green 

 shading off to purple at the apex and sides, the scutellum 

 black and the greater part of the prothorax black (with a 

 metallic tinge) in one and infuscate in parts in the other.

The sex of his specimen was not mentioned by Saunders ; 

 a female was subsequently described by Chapuis under the 

 name of Loxopleitrus nigrihts. The specimens of both 

 entomologists were from Tasmania, where the species is 

 fairly common. I have specimens also from Sydney and 

 Mt. Victoria (N. S. Wales). 



The sexes are alike in colour; the male, however, is 

 smaller than the female, with longer antennae, and the 

 space separating the eyes considerably less. 



Two specimens (sexes) from S. Australia have the 

 punctures (especially on the prothorax) considerably larger 

 (although perhaps not more numerous) than in the normal 

 form, but as there appear to be no other differences (even 

 in colour) I can only regard them as representing a variety.
