Long. 10|-12l millim. 



Agrees in some respects botli with 0. alpinus (Cliaud.) from Cliimborazo, 

 and C. dijschromus (Cliaud.) from Colombia, but the author's descriptions 

 founded on too few individuals, and imperfect in other respects, leave one in 

 doubt. I do not find an insect amongst Mr. Whymper's numerous series 

 having simply emarginated fourth joint to the middle tarsi like G. alpinus, 

 as Chaudoir's description implies, and the number of large punctures on the 

 third interstice is not 3 (except in rare instances) as in G. dyschromus but 4 

 or 5 ; they are very variable in position, and are very conspicuous on the 

 sericeous -opaque elytra of the $. The male is unusually brilliant in its 

 lilack colour. The thorax ^•aries greatly in -^v-idtli and rotundity of the sides.

Ent. Fr., 1878, p. 340. 

 A common insect in Colombia. Mr. Whymper obtained one example 

 from Milligalli (6200 feet). 



This is the only -species of Golpodes collected by Mr. Whymper belonging 

 to the third and most numerous section of the genus, characterised by its long 

 and narrow metathoracic episteina and almost universally metallic colours. 

 All the other species have very short episterna, and black or dark-brown 

 colours. 



Subfam. TRECHiNiE. 



39. Trechus ■? One Inoken specimen, undoubtedly of this genus, was 



taken on Cayamlie at 15,000 feet.

Hub. Tortorillas to Chuquipoquio, Chimborazo (12-13,000 feet); Haci- 

 enda of Antisana (13,300 feet); Valley of Collanes, Altar (12,500 feet); 

 Pichincha, first camp (14,000 feet); Cayambe (15,000 feet). Seven examples.
