INTRODUCTORY PAPERS ON ICHNEUMONID^. 205 



All the genus Heinalus were observed this month. H. velleda 

 was found on the moor, but very local. Calligenia miniata was 

 not very plentiful. 



Cidaria popidata came out in extra force the earlier part of 

 this month, and assisted the more numerous Y. ehitata in 

 bewildering the collector and preventing the capture of the more 

 aristocratic members of the Geometrina, supposing such to have 

 been present. 



About the middle of August the second brood of Eiqnthecia 

 jmnulata were obtained by beating furze-bushes, and towards the 

 end Larentia olivata turned up. Cidaria immanata and C. prunata 

 were not uncommon, neither was Botys asinalis ; this last is an 

 insect that requires breeding to get really fine specimens ; I took 

 a good number, but many examples were too poor in condition to 

 be worth setting. In the foregoing notes I have not set down 

 any of the Micro-Lepidoptera I met with, but will do so shortly 

 in a separate paper.
