64 MR. E. C. REED ON CHILIAN COLEOPTERA. [Jan. 6, 



distinct hind angles to the thorax ; and the sutural and ninth striae 

 only are deeply impressed throughout. Iu some examples there is 

 along and fine scutellar striole exterior to the sutural striae. Dejean 

 had only one example. 

 Southern Chili. 



Bradycellus tibialis, Sol. I. c. p. 268 {Acupalpus). 

 Very similar to B. unistriatus, but much smaller, with black 

 femora and rounded hind angles to the thorax. 

 Central Chili. 



Bradycellus chilensis. 



Bradycellus chilensis, Dej. I. c. p. 850 (Acupalpus) ; Sol. I. c. 

 p. 271 {Acupalpus). 



Common throughout Chili. 



Bradycellus arcobasis, Sol. /. c. p. 270 (Acupalpus). 



Differs from B. chilensis almost solely in its larger size. Equally 

 common. 



Obs. — All the above species have a distinct tooth in the emargi- 

 gination of the mentum, and therefore beloug to the genus Brady- 

 cellus of modern authors, and not to Acupalpus. The males have 

 the anterior tarsi only very slightly dilated ; and when there is a 

 scutellar striole, it is always exterior to the first stria. 



Acupalpus (?) pallidus, Sol. 1. c. p. 264. 



Acupalpus (?) bifossulatus, Sol. /. c. p. 266. 



I have not been able to recognize either of the above among the 

 large series of this group which I have collected in Chili ; I do not 

 know, therefore, whether they really belong to the genus Acupalpus. 



Subfamily Trechin^e. 

 Merizodus angusticollis, Sol. /. c. p. 186. 



This genus is very closely allied to Oopterus of New Zealand ; and 

 I am informed by Mr. H. W. Bates that his Oopterus maceyi, from 

 the Falkland Islands, is a Merizodus, having a bifid tooth to the 

 mentum ; in Oopterus this tooth is simple. 



This species is not uncommon in Southern Chili. 



Trechus chloroticus, Putzeys, Stett. Zeit. 1870, p. 19. 



Trechus ferrugineus. 



Trechus ferrugineus, Brulle, D'Orb. Voy. Ins. p. 43 ; Putz. I. c. 

 p. 20. 



Trechus ruficollis, Putz. I. c. p. 31. 



Trechus obscuricornis, Putz. /. c. p. 32. 



Trechus cyclopterus, Putz. I. c. p. 40.
