DESCRIPTIONS OF CHALCIDITES. 4G9 



the praescutum and scutum being very short and external, but 

 covered above by the mesothoracic scutellum, and the meta-

 vestigation of this subject, by examining the highly-magnified 

 figures contained in the four anatomical plates, published in 

 Mr. Griffiths's Translation of the Animal Kingdom, in which, 

 for the purpose of elucidation, I have uniformly represented 

 each of the three thoracic segments in the different orders by 

 a different colour, — the prothorax pink, the mesothorax blue, 

 and the metathorax yellow.
