List of Species Collected in the Centennial Buildings in Foreign Exhibits. 



COLEOPTERA. 



SlLVANUS SURINAMENSIS. 



Argentine Confederation and Brazil, in various materials. 



L;EMOPHL(EUS FERRUGINEUS. 



In beans, Brazil. These two species lived upon the debris of Bruchus, and were ac- 

 companied by a species of Fsocus. 



Bruchus picturatus, Fahrceus. 



Argentine Confederation ; in seeds of two leguminous plants, one of which produces 

 a screw bean, resembling Stromhocurpus of Arizona. 



Bruchus, sp. 



Allied to B. prosopis, of Arizona and New Mexico. Argentine Confederation ; also 

 in the screw bean. These two Bruchi are depredated upon by three small species of Ich- 

 neumonidae. 



Bruchus, sp. 



Of larger size and more uniform colour. Argentine Confederation, in the seeds of 

 another leguminous plant, allied to Prosopis. 



Bruchus, sp. 



Of larger size and more mottled colour ; in the seeds of three other leguminous 

 plants of the Argentine Confederation. 



Bruchus scutellaris. 

 Venezuela, in beans. 



Bruchus obsoletus. 



In beans from various countries of both coutiueuts. 



Bruchus pisi. 



In peas ; Spain and Portugal. 



Bruchus, sp. 



A small broad species, with traverse prothorax ; male rather uniformly clothed with 

 grey-brown pubescence ; antennm as long as the body ; female black, with a grayish-brown 

 broad dorsal stripe on the prothorax, and a small transverse white band on each elytron, 

 extending from the side margin nearly to the suture, a little in front of the middle ; thighs 

 not toothed. Length -09 inch. 



Brazil, in a bluish-gray variety of bean. I cannot identify this species among those 

 described in Schonherr's work ; it is of the same form, and belongs to the same division 

 as B. pisi, but is much smaller, and quite different in other characters. It is the only one 

 of the species here mentioned which is capable of being introduced ; and I have, therefore, 

 given such a description as will enable it to be recognised. The antennse are only feebly 

 serrate. This species is mentioned by Mr. Riley as B. granarius, but it does not agree 

 with the figure of Olivier. 



Rhizopektha pusilla. 



Victoria, Australia ; in wheat. This insect has been previously introduced into the 

 "United States in Persian wheat, distributed by the Patent office. {Vide Lee. Class, Col. 

 N. Am. p. 208.) 



Calandra oryz^. 



This destructive insect abounded in exhibits of corn (maize), wheat, and rice from 

 every part of the globe. I also observed it in arrowroot from Brazil.
