A. vitticolli sat similis, supra opaca, subtus viridis vel cyanea, nitida ; capite antice leviter concavo, viridi, con- 

 fertim rugoso ; thorace reticulato, viridi, disco nigro-fusco, linea mediana viridi ssepe postice abbreviata ; 

 elytris subtiliter rugosis, striatis, obscure purpurascentibus, fascia paullo ante mediam obscure rufa 

 ornatis, sutura basi et ad apicem viridi. 



Long. 2| lin. 



Hah. Mexico, Presidio (Forrer), Acapulco in Guerrero (Hbge). 



This species resembles A. vitticollis, but is relatively a little shorter. The head is 

 less impressed in front. The thorax is rather more convex, lightly impressed near the 

 hind angles, with a fovea in front of the scutellum, which is green. The elytra are 

 less narrowed at the apex. In some specimens the green colour in the middle and at 

 the sides of the thorax is very obscure or absent, as is also the red fascia of the elytra. 



POLYCESTA (p. 18). 



I have now before me five specimens of this genus, belonging to four or five species, 

 but without making a study of the genus and an examination of original types, it is 

 impossible to name them satisfactorily. The following was overlooked in the earlier 

 part of this work. 



3. Polycesta cribrana. 



Polycesta cribrana, Mann. Bull. Mosc. 1859, iii. p. 182 \ 

 Hab. Mexico 1 . 

 Only known to me from description. 



ACHERUSIA. (To precede the genus Thrincopyge*, p. 19.) 

 Acherusia, Lap. & Gory, Mon. i. p. 1 (1836). 



Three species of this genus have been described, all from Brazil. 



l. Acherusia piliventris. 



Acherusia piliventris, Saund. Trans. Ent. Soc. Lond. 1869, p. 8, t. 1. fig. 7 1 . 

 Hab. Mexico, Temax in Northern Yucatan (Gaumer). — Brazil 1 . 



The Mexican specimen differs from the type in being larger (5J lines long), and in 

 having the elytra darker with scarcely any trace of the coppery-red colour on the 

 shoulders. 



ACM^EODERA (p. 20). 



Acmaeodera cuprina (p. 20). 



To the Mexican localities given, add : — Tacambaro in Michoacan (Edge), Amula in 

 Guerrero 6000 feet (H. H. Smith). 



* This name was accidentally misprinted Trincopyge, on p. 19.
