also those only genetically identified) not heretofore known 

 from this part of South America. The genera not heretofore 

 reported including the 6 above, are 24 in number. It will be 

 seen that in spite of the smallness of the number of forms it is 

 not without interest as a help to the proper knowledge of the 

 distribution of forms in the Neotropical Region. 



Attention is called to certain variations in classification and 

 ir family names. This is owing to the arrangement of fami- 

 lies being in accordance with Reuter's masterly new system 

 (Bemerkungen iiber mein neues Heteropterensystem," Ofr. 

 Finsk. Vet. Soc. Fort. Bd. liv: 1911-12, afd. A, No. 6, pp. 1-62 

 [of separate?]), a system which, while in my opinion suscep- 

 tible of certain modifications, is nevertheless a most distinct ad- 

 vance on any now recognized. 



It is hoped that this fragment may be found of use and in- 

 terest in a survey of the neotropical fauna. 



Family THYREOCORIDAE. 

 Cydnus sp. One specimen from Mallali. 



Family SCUTELLERIDAE Reut. 



Augocoris sexpunctatus Fabr. Four specimens from Mallali. 



Family CIMICIDAE (Kirk.) 

 (= Pentatomidae Reut. et auctt.) 



Mormidea ypsilon Linneus. Mallali and Bartica in numbers. 

 This is seemingly the most abundant Cimicid as well as one of 

 great range in America South of the Rio Grande. It is somewhat 

 variable in coloration, size, and form of the thoracic spines. 



Solubea ypsilongriseus de G. Bartica and Mallali, common. Ap- 

 parently not heretofore recorded from British, although known 

 from Dutch, Guiana. 



Sibaria armata Dallas. One only from Bartica, although both 

 Van Duzee and Osborn have received it in abundance from the 

 same place. 



Galedanta myops Fabr. One example from Mallali. 



Euschistus acutus Dallas. One each from Mallali and Bartica. 



Euschistus heros Fabr. Mallali, one only. 



Berecynthus delirator Fabr. Four from Bartica and one from 

 Mallali. 



Taurocerus edessoides Spinola. This pretty species is repre- 

 sented by three examples from Bartica. 



Arvelius albopunctatus Deg. Mallali, one specimen.
