at the skies and base, apex smootli ; under-side and legs shining castaneons, with

 smooth, the fi'ontal eraargination shallow, almost lunate ; metasternum faintly trans-

Elongate-oval, shining testaceous, the prothorax sometimes with a tinge of red- 

 dish-brown, or varied with fuscous on the disc ; the elytra usually with the suture, 

 and one or two dorsal stripes, of a dark brown ; head and prothorax apparently 

 impunctate, sides of the latter very feebly rounded ; elytra convex, the greatest con- 

 vexity before the middle, finely seriate-punctate, obsoletely so at base and sides, apex 

 smootli ; under-side shining testaceous, varied with brownish, or entirely brownish, 

 the legs in all cases a little paler ; outer joints of antennae black ; prosternum as in 

 cBneomicans ; mesosternum rather more deeply notched than in that species, slightly 

 convex, usually plane, sometimes with an angular impression at each side ; meta-

Note on the Carabideous genus Maraga, WalJcei'. — Baron Chaudoir, in his 

 recently published monograph of the genus Orthogonitis and its allies, expresses sur- 

 prise at the genus Maraga being united by von Harold and Gemminger with Ortlio- 

 gonius. Maraga is, however, undoubtedly identical with Orthogonius, and Baron 

 Chaudoir's surprise is probably to be accounted for by the fact of the characters given 

 by Mr. Walker being in part erroneous ; as the palpi are not " sub-securiform," 

 and the posterior femora are not " bidentate " in the type of M. planigera before 

 me. This species is the smallest (9 mill.) in the Musemn collection ; the head is 

 finely (but distinctly) and not very thickly punctured, with a distinct transverse 

 impressed line between the antennae. The thorax is transverse, slightly narrower in 

 front than behind, the anterior margin nearly straight, the sides evenly rounded, the 

 anterior angles much rounded, the posterior angles bluntly rounded ; the upper
