tyiwpanum of Fabricius. The Fabrician species is a well 

 known Brazilian form wliicli belongs to tlie . genus 

 Zam^nara Amyot. The last named author has added to 

 the confusion by referring the species of Beauvois to the 

 largest and finest form of Zammara yet discovered in 

 Brazil, and has given it the name Z. strepens. This 

 Zammara has nearly the same markings of pronotum 

 and wings as our species from San Domingo, but it 

 belongs to a different genus. The Brazilian one is much 

 too large and broad to agree with the figure of Beauvois. 

 Morever, the species of Beauvois was given as from San 

 Domingo, presumably from near Cape Haitien, where he 

 lived and collected many insects, and from which country 

 no large Zammara of this type has yet been collected. 

 The Z. strepe7is Amyot, Hemipt. p. 469, No. 2, is common 

 near Rio de Janeiro, and it appears to be merely the 

 best developed form of Z. tympanum Fabricius.
