 Common Rotche (Mergulus Alle).

 duced and notched with an oblong depression, and two 

 transverse semicircular chestnut lines proceeding from the 

 trabeculae to the centre, and two diagonal chestnut bands 

 from the eyes to the occiput, lateral margin deeply sinuated, 

 base convex and rotundate ; trabeculae large, strong, and 

 curved ; eyes dark and prominent ; antennae slender, sub- 

 clavate, and pale tawny ; prothorax small, transverse, with 

 a fuscous channel in the centre, posterior margin convex ; 

 metathorax about the width of the head, acutely angular 

 behind with a row of setigerous punctures ; abdomen large, 

 pale yellow white, with the first segment and the lateral 

 fasciae to the six following ferruginous, becoming gradually 

 darker towards the apex, the last two segments fuscous; legs 

 strong and thick ; anterior femora angular. Length . 



I find this species not uncommon upon the Jay (Gar- 

 rulus glandarius), and have received it from my brother, 

 found on the same bird in Norfolk.
