No. 115, Harris' Collection. " Sutton, Mass., Dr. Smith." 



This is a variety of P. circumcinctus Stal, and is named Pentatoma 

 clauda Say in Dr. Harris' list ; and was determined by Say. It is a 

 more robust form than the typical one of the latter author, and differs 

 from it in various particulars unnecessary to reproduce here ; but, 

 until we have fuller knowledge of the two species, it will be more 

 satisfactory to keep them separate. 



The extraordinary range of this species is worthy of remark. It 

 extends from the island of Trinidad, near the mouth of the Orinoco 

 River, and from Panama to Nebraska, Canada, and New England.

Another specimen in the collection has a printed number (400) and

 No. 19. Dr. Harris' Collection, <?, ?. "June 10, 1822." 

 Dr. Harris received the name Pentatoma maculiventris from Say, 

 but did not know whether its description was published or not. Cer- 

 tainly no description of it is to be found in the printed papers of Mr. 

 Say. 



3. P. serieventris . 



Podisus serieventris Uhler, Proc. Bost. Soc. N. H., 1871, p. 95. 



Similar to the preceding species in form and appearance, but of a 

 more blackish-gray color. Pronotum not so much sinuated each 

 side, the humeral angles less prominent, obtusely triangular, blackish; 

 the surface a little less regularly punctured, each side anteriorly and
