-204 MR. A. THOMSON'S REPORT ON THE INSECT-HOUSE. [Mar. 18, 



longitudinally sulcate and slightly rugose or wrinkled, also more 

 or less distinctly punctured. 



Hob. Ohanchamayo, Peru. 



Of the spotted form, a single specimen is before me ; these spots 

 are nearly round, one is placed at the base near the scutellum, 

 the other in a line near the apex. I look upon this specimen as 

 the normal form, although four others, contained in my collection, 

 have no elytral spots ; there are no other differences between the 

 two forms.
