This species would be better placed in the group having punctate-striate elytra than 



in the A. cenea group ; the foveolae of the elytra are caused, not by the coalescence of 



the striae-punctures, but by the number and size of the large punctures of the second, 



fourth, and sixth striae. The apical ventral segment has a triangular notch almost as 

 in A. auronitens. 



It is doubtful if the specimen described 



from the isthmus of Panama 



I 



think it probable that it was taken by Mr. Salmon, who collected chiefly in the Cauca 

 valley of Colombia. 





25. Agra rufoaBnea. 



Agra rufoanea, Chevrolat, Col. Mex. ii. no. 182 l . 



Hab. Mexico, Cordova (Salle x ). 



The type specimen (a female) in the Salle collection appears not to 

 with since it was taken by M. Salle, some time before 1835, the date of the description. 

 It is closely allied to A. panamensis, and has the apical ventral segment similarly 



have been met 



notched in the middle ; the punctures of 



alternate elytral 



however, very 



much smaller, and the legs &c. differently coloured 



26. Agra dimidiata. (Tab. xn. fig. 23.)

Hab. Mexico \ Toxpam (Salle). 



Unique in the Salle collection. The specimen is a female, with an extraordinary modi- 

 fication of the apical ventral segment, the apex being very broadly and deeply excised, 

 with a central spine curving down the middle of the excision from the body of the 

 segment. The eighth antennal joint is not abbreviated. 













27. Agra champion! 



A. dimidiates affinis; nigra nitida, elytris et abdomine castaneo-fulvis ; capite post oculos late quadrato, 

 occipite punctis nonnullis parvis; thorace post medium sat rotundato-dilatato, ante basin fere subito 

 constricto, antice gradatim attenuate, dorso lineatim grosse punctate ; elytris apice utrinque valde bispi- 

 nosis, punctulato-striatis, striis secunda et quarta punctis majoribus parum conspicuis. 



2 segmento ultimo ventrali apice late exciso, excisura bilobata, medio breviter spinosa ; antennis articulo 

 octavo haud abbreviate. 



Long. 19 millim. 







Hab. Panama, Volcan de Chiriqui (Champion).

One example only. 



The excision in the apical margin of the terminal ventral segment is so complex ii 

 outline that a verbal description is scarcely possible. It is a very broad bilobed notch 

 the body of the segment projecting as a square plate between the two lobes, and th( 

 front edge of the plate being spinose in the middle.
