Long. 9 millim. ^ . 



A slender and elongated species with relatively long but not large head, 

 ehjugated mandililes, prominent eyes, and narrow elongate-ovate elytra, the 

 4-7th stria^ of which are very faintly impressed. The legs are slender, the 

 tarsi clothed beneath rather densely with moderately fine hairs, and the fourth 

 joint in all bilobed, the outer lobes a little longer and broader than the inner. 

 The metathoracic episterna are very short. The thorax differs from that of 

 0. piceolus and allied species in not being deeply sinuated behind or having 

 produced posterior angles, the lateral margin being straight for some distance 

 Ijefore the angle. The colour of the thorax is a little redder than that of the 

 head and elytra. 



This species is evidently closely related to C. alpinus (Chaudoir) also irom 

 Chimborazo ; but the author's description of the stria3 does not accord with 

 G. Icevilateris, and the claw joint of the tarsi is without cilia. 



32. G. jnceolus, Chaudoir, Ann. Soc. Ent. Fr., 1878, p. 299. 



Originally taken in Colombia by Steinheil. Two examples taken by 

 Mr. Whymper on Cayambe at 12-14,000 feet agree very well with Chaudoir's 

 description ; but according to the author's synoptical table the foui-th joint of 

 the posterior tarsi ought to be without external lobe. Mr. Whymper's insect 

 has a distinct narrow pointed lobe ; it is, however, difficult of detection, and 

 may possibly have been overlooked. I am unwilling to consider it as a dis- 

 tinct species. An example sent me by M. Putzeys (who supplied M. de 

 Chaudoir with specimens) as G. yiceolus^ is extremely like Mr. Wliympei''s, 

 but the basal plica of the elytra is obsolete and the base so narrow that the 

 humeral angles are brought near to the base of the thoi'ax ; it cannot there- 

 fore be Chaudoir's species, and was evidently mistaken for it by Mr. Putzeys 

 owing to its close resemblance.
