Hah. — Pebas^ Upper Amazons. 



The present insect forms almost an intermediate link 

 between G. regalis and G. cliscors, agreeing in colouring 

 with the former J and in form of thorax, antennee, and 

 sculpture of elytra with the latter : from G. regalis it 

 may be at once known by the much more slender an- 

 tennee, and by the finer sculpture of the elytra ; the form 

 of the thorax is also entirely different; in G. regalis this 

 part of the body is much broader, and the sides are 

 obliquely rounded, and dilated considerably beyond their 

 middle ; in G. connectens (as also in G. cliscors) the thorax 

 is narrower, its sides are first produced almost directly 

 outwards (being only slightly and obliquely rounded) 

 to their middle : thence to their base they are nearly 

 parallel, and very obtusely rounded. The diagnosis 

 between G. discors and the species under considera- 

 tion is rather more clifiicult : the two insects entirely 

 agreeing in the slender antennse and form of thorax, but 

 difii"ering both in colouring and in the general form of 

 the body. The $ of G. connectens (judging from a single 

 specimen in my collection) is more rotundate and less 

 narrowed towards the apex of the elytra ; whilst the $ 

 is more decidedly triangular in form, the elytra being 

 broader and less narrowed at the shoulders than in G. 

 discors; the red colour on the elytra is confined in G. 

 discors to a large ovate patch on the anterior half of the 

 dilated border; in G. connectens it forms a broad sub- 

 marginal stripe, similar to that on the elytra of G. regalis.
