Micronotus caudatus (Saussure). 



1861. T[cUix] caudata Saussure/ Revue et Magasin de Zoologie, 2e ser., 

 XIII, p. 399. [Guiana.] 



Igarape-assu. Three males, five females. 



These specimens are typical of this relatively widely distributed 

 species. It seems to us very probable that Bruner's Tettix gracilis 

 from Trinidad'^ equals the present species. 



Apotettix bruneri (Hancock). 



1906. Apotettix bruneri Hancock, in Bruner, Proc. U. S. Nat. Mus., XXX, 

 p. 614. [Paraguay.] 



Igarape-assu. One female. 



This specimen is inseparable from Paraguayan and Argentinian 

 individuals of the same sex. The range of the species is much 

 extended to the northward by this record. 



Tettigidea hancocki Brun^^r, 



1910. Tettigidea hancocki Bruner, Ann. Carneg. Mus., VII, p. 131. [Cor- 

 umba, Brazil.] 



Igarape-assii. One male. 



This specimen fully agrees with the description of hancocki, but 

 in size it is somewhat smaller, showing the following proportions: 

 length of body, 8.8 mm.; length of pronotum, 9.1; length of tegmen, 

 1.7; length of wing distad of pronotum, 2.5; length of caudal femur, 

 5.4. 



The two localities from which this species are known are widely 



separated, but doubtless it will be found in suitable situations in 



the intervening region. 



Proscopinse. 



Proscopia scabra Klug. 



1820. Proscopia scabra Klug, in Nees ab Esenbeck, Horse Physicae Berolin., 

 p. 19, pi. Ill, fig. 2. [Pard, Brazil.] 



Para. (C. F. Baker.) One male. 



The male is particularly interesting in having a striking type of 

 coloration, a median supra-clypeal area on the lower face, the ventral 

 section of the gense, the cephalic supracoxal plate, a wash along each 

 side of the meso- and metapleura and the greater portion of the 

 immediate apex of the abdomen, being yellowish. The species 

 Taxiarchus paraensis described by us from Obidos, Amazon River,^* 

 we find to be a synonym of the present species. The unsatisfactory 

 character of Brunner's generic key and lack of comparable material 

 were largely responsible for the reference of this insect to Taxiarchus.
