 tions du Musee Civique de Genes. < An. Mus. Civ. 

 Stor. Nat. Geneva, Serie 2 a , Vol. xx (XL), pp. 531- 

 541. 



Treats principally of Pentatomidse, but describes Belosto- 

 ma gestroi on page 537. 



(18) 1900. Hemipteres exotiques ou peu connus des collec 



tions du Musee National Hongroise. < Termesztrajzi 

 Fiizetek, Vol. xxxn, pp. 414-422.

geographiques, descriptions d'especes nouvelles. 



< Bull. Soc. Sci. Buc., An. xn, No. 1-2, pp. 97-121. 



Describes new species in Nepidse and discusses others in 

 the family, including Nepa apiculata Uhler, and goes more 

 at length into synonymy of the belostomatid genera and 

 species. Very necessary for nomenclature of the latter 

 family. 



(20) 1903. Deux nouvelles especes du genre Belostoma Latr.

Describes three extremely interesting forms from South 

 America, one being a species of the genus Matinus Stal, 

 heretofore known only from Australia.

This list of papers, as finally worked out, with an index of 

 families, subfamilies, genera, and species added, becomes prac 

 tically a preliminary check list of these families of Cryptocerata 

 for America, and will for this reason be useful to workers in 

 this section of the Hemiptera.
