NOTES ON GUATEMALAN HEMIPTERA WITH 

 DESCRIPTIONS OF A FEW NEW SPECIES. 



Herbert Osborn. 



During the winter of 1905 Prof. J. S. Hine made a collecting 

 trip in Guatemala and the Hemiptera collected, except the 

 aquatics, have been turned over to me. As the material in this 

 collection adds new localities for many of the species recorded 

 in the Biologia Centrali Americana, in some instances entirely 

 new records for the Central American region, and also some few 

 species that appear to be new to science, it seems desirable to 

 give a list of all the species so far as determined with the records 

 of the localities where collected and such notes on distribution 

 as may add to our knowledge of the geographical range of the 

 species. The localities worked by Prof. Hine were Puerto Bar- 

 rios near the coast and Morales, Los Amates, Gaulan, for the 

 Atlantic slope; and Guatemala City, Amatitlan, Santa Lucia, 

 Mazatenango, San Jose, for the Pacific slope. Considering the 

 time during which the collections were made and that quite a 

 number of species are still undetermined, this list must be con- 

 sidered as quite extended particularly if we note that Hemiptera 

 were only one group in which collections were made. 



As it is but a few years since the appearance of the "Biologia" 

 articles on Hemiptera of this region, it seems unnecessary to 

 attempt a full bibliography and only such citations of references 

 or synonomy are given as seem necessary to properly locate 

 the species or to correct what appear to be erroneous references 

 in previous articles. The work in the " Biologia" seems to have 

 been done with too little regard to determination of the previously 

 described forms and there is a large number of new species des- 

 cribed which will probably have to be reduced to synonyms 

 when the fauna is more carefully worked.
