indicated by Mr. Waterhouse as belonging to that portion of Feronia 

 to which the name of Pterostichus has been assigned : it is apterous, 

 and measures 5j lines in length and nearly 2 in breadth. Mr. Darwin 

 brought specimens from Ynche Island, Valdivia and East Chiloe. 

 (Id. 123). 



8. Feronia area, Dejean, iii. 279 ; synonymous with Osmaseus mar- 

 ginalis of Curtis, Linn. Trans, xviii. 191. Five specimens from Val- 

 paraiso.

 xviii. 191. Two specimens from East Chiloe, one from Valparaiso, 

 and a fourth from Conception. 



10. Feronia lucida, the Pterostichus lucidus, Curtis, Lin. Trans.

11. Feronia meticulosa, Dejean, Supp. v. 762. Mr. Darwin brought 

 three specimens of this insect from Valparaiso. (Id, 124). 



12. Feronia marginata. Black or piceous, with the antennae and 

 feet rufo-piceous : the prothorax is subquadrate, and rather broader 

 before than behind, and has all the angles rounded : the posterior fo- 

 vea? are indistinct : the elytra are but little wider than the prothorax, 

 and striated ; the sutural stria is quite distinct, the following four are 

 scarcely so, the third has a basal and median impressed point, the la- 

 teral margins have three distinct striae. Mr. Waterhouse places this 

 insect in the section that has been called Steropus : it is 3f lines in 

 length and 1 J in breadth. Mr. Darwin brought many specimens from 

 Valparaiso and Conception. (Id. 124). 



13. Feronia Peruviana, Dejean, iii. 233. 



14. Feronia Chaudoirii, Guerin. 



15. Feronia Guerinii. Black, shining: prothorax subquadrate,

 tween them being punctured : the elytra are striate, and the striae indis- 

 tinctly punctured : the three basal joints of the antennae are nearly black 

 in the middle, with the extremities red. Mr. Waterhouse considers this 

 species as belonging to the division Poecillus : it is 5 lines in length 

 and 2 in breadth. Mr. Darwin found a specimen of this insect at 

 sea, 60 miles from Rio de la Plata. (Id. 125). 



16. Feronia depressa. Black, cupreous or aeneo-cupreous above : 

 prothorax nearly square, somewhat contracted anteriorly : all the an- 

 gles rather obtuse : the posterior foveae long, impunctate, groove-like, 

 situate midway between the dorsal channel and the outer margin : the 

 antennae are rather short and stout, with the three basal joints testa- 

 ceous. This is also a Poecillus : it is 5j to 5f lines in length and If
