HYMENOPTERA. 

 Family FORMICHLE. 



A dark-colored species of the genus Camponotus was collected, one 

 male from Albemarle Island, numerous males and two females from 

 Charles Island. 



Of a light-colored species of the same genus seven males were taken 

 on Charles Island, and one male on Albemarle Island. 



Family APID^E. 



Two females of the genus Xylocopa of a purple-black color, even the 

 wings, were taken on Indefatigable Island. On this island was also 

 collected a male specimen that may be of the same species. It has 

 transparent wings, and the body is covered with pale rufous hairs. 



DIPTERA. 



Family CULICID.E. 



Twelve specimens of the genus Cule.r were collected, of a luteous 

 color, with blackish mesonotum. 



CHILI AND STRAITS OF MAGELLAN. 

 COLEOPTERA. 



Family CICINDELID^E. 

 Agrius fallaciosus Clievr., Ann. Fr., 1854. 



A specimen was collected on Elizabeth Island of this rare and ex- 

 ceedingly interesting form. It occurs ouly at the straits, aud is the 

 only South American representative of the group to which our genera 

 Amblychila and Omns belong. 



Family CARABID^E. 

 Carabus suturalis Fab. 



Three specimens from Sandy Point, aud one from Laredo Bay, of this 

 species. It occurs also in Chili, and is of a graceful form and brilliant 

 color, like the other Chilian species of Carabus. Some authors sepa- 

 rate them into the genus Ceroplossus. 



Migadops ovalis Wateih., Ann. Nat. Hist., 1842. 



One specimen from Laredo Bay. The genus is peculiar to Patago- 

 nia aud the Falkland Islands. 



Six different species belonging to the genus Antarctia were collected. 

 Two specimens of one species were caught on board near Chiloe, another 

 pair- of a different species on board a long distance southwest from 

 Chiloe. At Sandy Point were taken nineteen specimens of three species, 

 and at Laredo Bay two specimens of the sixth species. The species are 

 so nearly allied, and so large a number have been described from Chili 

 and Patagonia, that it is not safe to identify them without comparison
