I have named this species after Mr. G. Compere, of W. Aus- 

 tralia, who is rendering very valuable service in his investigations 

 of insect parasites. 



N.B. — Since writing the above description I have seen male 

 examples in the collection of Mr. Griffith (which I hesitate to 

 separate from this species) evidently more nitid than the type and 

 having the frontal tubercles prolonged into considerable h irns 

 and the front of the pronotum quite strongly retuse.
