Igarape-assu. Three males. 



These specimens fully agree with the description of the species. 

 The status of three unquestionably related forms, i. e. lateralis 

 Burmeister, minutissima (DeGeer)^ and pumila (Stal), we are 

 compelled to leave in abeyance for the present, although it is quite 

 probable that one at least is the same as the present species. The 

 original descriptions are so brief that little other than the general 

 relationship of the species can be ascertained from them, and the 

 desired more detailed information can only be gleaned from the 

 types or topotypic material. 

 Anaplecta bivittata Bnmner. 



1865. A[naplecta] bivittata Brunner, Nouv. Syst. Blatt., p. 63. [Brazil.] 



Igarape-assu. One male. 



This specimen shows some points of difference from the original 

 description, but it is apparently the same species. The head is not 

 wholly rust color, as described, the interocular region of the vertex 

 being blackish brown, while the tegminal maculation does not 

 reach the costal margin of the same, but does, however, border 

 the humeral trunk to the distal squarely truncate margin of the 

 maculation. 



This is apparently the first definite locality for the species. 



Pseudomopinse. 



Pseudomops annulicornis (Burmeister). 



1838. Th[yrsocera] annulicornis Burmeister, Handb. der Entom., II, abth. 

 II, pt. 1, p. 500. [Bahia, Brazil.] 



Igarape-assii. Two males, four females. 



These specimens fully agree with the description of Walker's 

 Pseudomops deceptura from an unknown locality, which is considered 

 a synonym of Burmeister 's species by Shelf ord. The original 

 description of annulicornis is extremely brief, so little can be learned 



3 We cannot agree with Shelf ord in his placing this species as a Holocompsa 

 (Trans. Entom. Soc. London, 1908, p. 464) from the evidence of the alleged type. 

 The description and figure given by DeGeer are undoubtedly of an Anaplecta 

 and it is not at all difficult to see which species are its closest relatives. It seems 

 evident that Shelford did not see the material on which DeGeer based his species 

 and ad interim the Holocompsa specimen was probably by accident associated with 

 DeGeer's label. DeGeer's original description says of the insect: "Sa couleur 

 est d'un brun noiratre et tres luisant; c'est aussi la couleur de la plaque du corce- 

 let, qui est arrondie, mais dont les deux bords lateraux sont blancs & tres trans- 

 parents." This would clearly apply to an Anaplecta of the present group and 

 certain other characters mentioned, as the folding of the wings, make the identifi- 

 cation even stronger. The redescription of the "type" by Shelford presents the 



following features comparable to those quoted above from DeGeer: "Head 



with rufous pubescence. Pronotum fuscous with a recumbent rufous pubescence. 

 Tegmina with marginal area with rufous pubescence." Further comment seems 

 unnecessary.
