I. c. p. 251 (Feronia (Argutor)) ; Sol. I. p. 232 (Feronia). This species has the metathoracic episterna long and narrow, the presternum distinctly margined at the end, the hind tarsi gloved at the sides ; but the elytra have a long scutellar striole, unlike the typical Lagari. The thoracic foveae are single on each side and sulciform, similar to the North-American Lagarus erythropus. Common in Central Chili. PTEROSTICHUS ERRATICUS. Pterostichus erraticus, Guer. Mag.

Elongatus, subparallelus, niger subnitidus, palpis piceis ; capite postice hand angustato, oculis vix prominentibus; antennis paulo compressis; thorace elongato quadrato-cordato, postice gradatim sinuatim angustato, angulis posticis rectis, busi lavi, foveis profundis; elytris humeris rotundatis, postice paululum dilatatis, apice late rotundatis sinuatis, supra punctato-siriatis, interslitiis paulo convexis, tertio unipunctato. Long. 9-9£ lin. 6 $ • This species offers all the chief characters of the European genus Percus, of which it has also the facies, resembling a small, slender P. siculus. The elytra are destitute of basal fold, the scutellum lying on the depressed pedicle; behind, the margins are a little ex-planated before the sinuation, and have there two marginal striae exterior to the row of large punctures. There are no humeral carinae ; and the striae are rather loosely and not deeply punctured ; a rudiment of basal striole exists in the form of a fovea on each side of the apex of the scutellum. The fovea on each side of the base of the thorax is distant from the angle, broad and deep; the dorsal line also terminates behind in a deep impression. This species is possibly the Feronia (Platysma) convexipennis, Fairmaire, Coleop. Chil. pt. i. p. I ; but as that author places it in the section Platysma, to which it has not the slightest resemblance, and does not mention the absence of basal fold to the elytra, which is the most conspicuous feature of the species, the identity is much open to doubt. Even if it be the same, Fairmaire's name cannot be |
