to 2 lines in breadth. Mr. Darwin took three specimens at Monte 

 Video. (Id. 126). 



17. Feronia Patogonica. Black, the underside inclining more or 

 less to pitchy red : this little insect Mr. Waterhouse thinks may pro- 

 bably be the Feronia ohlita or Fer. Bonariensis of Dejean : the pro- 

 thorax is subquadrate, rather narrower posteriorly, without punctures 

 and having the foveae groove-like : the elytra are considerably broader 

 than the prothorax, and striate, the striae being impunctate. This is 

 an Argutor of our British arrangements : it is 85: lines in length and 

 1^ in breadth. There are specimens from Maldonado, Monte Video, 

 Santa Fe &c. ; all, with the exception of one from Monte Video, are 

 furnished with wings. (Id. 126). 



18. Feronia Brullei. Pitchy black, the suture and outer margins 

 of the elytra inclining to pitchy red : the prothorax is subquadrate, 

 narrower posteriorly ; the posterior foveae are long, narrow grooves, 

 extending to the posterior margin : the elytra are considerably broader 

 than the prothorax, and deeply puncto-striated. This species is also 

 an Argutor, and is furnished with wings ; it is 3f lines in length and 1 J 

 in breadth. A single specimen was brought from Santa Fe. (Id. 127). 



19. Feronia Audouini. Black : the prothorax is subquadrate and 

 without punctures, broader than long, the angles being slightly round- 

 ed : the posterior foveae are long, narrow grooves, extending to the 

 posterior margin, and are connected by a transverse groove ; the ely- 

 tra are striated, but the striae are impunctate. This species (also an 

 Argutor) is furnished with wings ; it is 4 lines long and li broad. — 

 Mr. Darwin brought it from Santa Fe. (Id. 128). 



20. Feronia apicalis. Black, with a distinct pitchy red patch at 

 the tip of the elytra, which are striated, the striae near the suture being 

 deeper, the lateral one faint, and all without punctures : the prothorax 

 is subquadrate, rather narrower irojteriorly, and without punctures. — 

 This species (also an Argutor) is furnished with wings, and is 4^ lines 

 in length and If in width : it is from Maldonado. (Id. 128). 



21. Feronia (Argtitor J Chilensis, Dejean, iii. 251. Of this species 

 Mr. Darwin brought two specimens from Valparaiso, and one from 

 South Childe.
