SUPPLEMENT. 



Duking the publication of the foregoing account of the Central- American Buprestidse 

 several small collections have been received, containing many species new to our fauna 

 and additional specimens of recorded species from localities other than those already 

 noted. Hence this Supplement. 



CHALCOPHORA (p. 1). 



Chalcophora virginiensis (p. 2). 



To the localities given, add : — Mexico, Zapotlan in Jalisco (Edge); Honduras, Bonacca 

 Island, Bay of Honduras (Gaumer). 



In my remarks on this species mention is made of two Mexican examples which 

 differed from the typical form in having the smooth parts of the thorax wider and the 

 sides sinuate before the posterior angles. A good series of this form has now been 

 received from Zapotlan (Edge), but I still hesitate to give it a distinctive name. 

 All the specimens agree in having the smooth parts, and especially the median line, 

 broader than in any North-American examples before me ; but there is a specimen 

 in the British-Museum Collection labelled Mexico which, while agreeing in general 

 aspect and the sinuous sides of the thorax with the others from Zapotlan, has the 

 median smooth line of the thorax narrow. The specimens from Zapotlan vary greatly 

 in the form of the thorax, some having the sides very strongly angular before the 

 middle and sinuous before the posterior angles ; most of them have the sinuosity only 

 moderate, and one or two examples have the sides almost parallel behind. The elytra 

 in the Zapotlan specimens have the longitudinal submarginal impression at their apex 

 narrow and rather sharply denned, a character in which they differ from the North- 

 American examples. The two Mexican specimens in the British Museum are slightly 

 intermediate. 



PELECOPSELAPHUS (p. 3). 



Pelecopselaphus acutus (p. 3). 



To the locality given, add : — Guatemala, Chimaltenango (Conradt) ; Panama, Bugaba, 

 800 to 1500 feet (Champion). 



MIXOCHLOEUS (to precede the genus Agceocera, p. 4). 

 MixocUorus, Waterhouse, Trans. Ent. Soc. Lond. 1887, p. 177. 



The species upon which this genus is founded has much the appearance and coloration
