American Caraboidea 285 



Pinacodera were well known at that time, it is probably a true 

 Cymindis as described. In ampUata the upper surface of the tarsi 

 is glabrous and canaliculate along the middle, this depression not 

 being discoverable in the other species; the sculpture and hairs 

 of the strial intervals also render it quite isolated in the genus. 



The species fuscicollis and Icevigata of Motschulsky, the latter 

 at least being from Mobile, I have not seen, and can therefore 

 form no estimate of their systematic position; they are said to be 

 identical with limhata by Horn, but this is altogether improbable, 

 limhata being a northern species and peculiarly marked. I have 

 also been unable to examine any representatives of semisulcata 

 and sulcipennis of Horn, from Lower California. Platicollis is 

 very peculiar in the greater number of dorsal setigerous punctures 

 of the elytra and their extension to other intervals than the third; 

 as Dejean is careful to mention three dorsal punctures, and his 

 description accords otherwise, there is barely a doubt that the 

 complanata of that author is the same species; the synonymy of 

 russata is, however, taken from Horn and may or may not be correct. 



Cymindis Latr. 

 This genus is closely allied to Pinacodera but, besides differing 

 in the hairy upper surface of the tarsi, the form of body is more 

 slender as a rule, the sculpture deeper, coarser and more conspicu- 

 ous and the pubescence more abundant and coarser, giving to the 

 species a different and characteristic habitus. Several of the special 

 features noted under the preceding genus can also be observed here, 

 for example, the small cluster of setse at the apical angles of the 

 prothorax and the irregular setigerous dorsal punctures of the 

 elytra — very rare in Pinacodera but noticeable in platicollis. The 

 revision of the genus given by the writer a few years ago (Mem. 

 Col., IV, p. 177) is to be modified by the removal of atroliicens, 

 blanda and planipennis Csy. nee Lee. {Pinacodera ampliata Csy.), 

 to form part of the genus Pinacodera, and the addition of the three 

 following: 



* Cymindis agitata n. sp. — Moderately convex and ventricose, polished 

 throughout, piceous-black, the elytra black, with the reflexed margin 

 pale, the pronotum also diaphanously pale at the sides; under surface 

 rufo-piceous, the abdomen black at the sides and apex — a form of color- 

 ation generally visible in Pinacodera, the legs rufous; head four-fifths
