4 SEEEICOENIA. 



This species resembles P. frontalis in general form, but is larger, has the thorax 

 more strongly punctured in front and at the sides. The elytra have not the purple 

 spots, the punctures are closer and smaller, and the scutellar region is smooth. 



5. Pelecopselaphus lateralis. (Tab. I. fig. 4.) 



Supra oliyaceus, subtus lsete cupreus ; capite cupreo, fortiter punctato, thorace lato, ante medium parum 

 angustato, sat crebre fortiter punctato, linea mediana impressa margineque laterali cupreis; elytris 

 tborace haud latioribus, singulis costis tribus bene elevatis, interstitiis crebre punctulatis, regione 

 scutellari lseviore. 



Long. 11 lin. 



Bab. Mexico, Tuxtla, Playa Vicente (Salle); Nicakagua, Chontales (Belt). 



P. lateralis is nearest to P. angularis ; but it is shorter, the thorax is less narrowed 

 in front, and the lateral line (viewed from the side) instead of being greatly oblique, 

 suddenly bends down in the middle (Tab. I. fig. 4, a). 



AGJEOCERA. 



This genus is inserted in Mr. E. Saunders's ' Catalogue of Buprestidse,' p. 50; but it 

 appears never to have been characterized. The species for which it is proposed is 

 Anthaccia gigas, Lap. & Gory. This species stands under Pelecopselaphus in Gemminger 

 and Harold's catalogue, and in its generic characters (in the structure of the sterna and 

 intercoxal process of the abdomen) it undoubtedly approaches very nearly to that 

 genus. I think, however, that it may be better to adopt the genus Agwocera as 

 distinct from Pelecopselaphus, on account of the trisulcate thorax, the suture of the 

 elytra not depressed at the base, and joined by a short costa near the scutellum, the 

 apical margins of the elytra not acutely dentate, but with a few crenulations or quite 

 simple.

Anthaxia gigas, Lap. & Gory, Mon. ii. (Anthax.) p. 2, t. 1. f. I 1 . 

 Hab. Mexico, Orizaba (Salle), Plan del Rio (Edge). 



Originally described as from the East Indies 1 , this species has since been found 

 to inhabit Mexico. A specimen in the British Museum compared by Mr. Saunders 

 with the original type bears this latter locality. It varies in size from 6f to 8| lines. 

 The colour varies from green (with the suture of the elytra narrowly coppery) to deep 

 copper-colour. 



2. AgsBocera scintillans. 



Yindis ; elytris confertim ruguloso-punctatis, singulis costis tribus nitidis, prima tertiaque abbreviatis.
