The shape of the head is more quadrate than in the preceding 

 •species, but in generic characters the two agree very well.

 °N. hilaris.

Determined by Mr. Say as his P. hilaris. Other synonyms will 

 probably be hereafter added to this species. It is found in the West 

 Indies, and extends as far south as Para, Brazil. Specimens have 

 been sent to me from Canada, Maine, Massachusetts, New York, 

 New Jersey, Pennsylvania, Maryland, Florida, Louisiana, Texas, 

 Panama, Cuba, Hayti, and the above-named locality. Another spec- 

 imen with the printed number 249, "Wilcox ? N. Y.," is in the col- 

 lection. 



Khaphigaster Amyot et Serv. 

 R. pennsylvanicus. 



Cimex viridis pennsylvanicus De Geer, Memoires, nr, 330, pi. 34, 

 fig. 5. Pentatoma abrupta Say, Heteropt., 6, 10. 



No. 129, Harris' Collection. " Cambridge, Mass., Mr. Randall." 



Through the courtesy of Dr. Stal, of Stockholm, Sweden, I have 

 been able to recognize this species of De Geer, which has hitherto 

 remained unknown to our entomologists. Say's specimen came from 

 Georgia, but I have a poor specimen from Panama, and I have exam- 

 • ined others from New Jersey, Mass. , and Illinois. The decidedly 

 rounded outline and bluntly rounded humeri well agree with De 

 Geer's figure, while the preceding species, to which it has been re- 

 ferred, is much more angular, particularly on the humeri. 



Thyanta Stal. 

 T. custator. 



Cimex custator Fab., Syst. Rhyng., 164, No. 43. Pentatoma cus- 

 tator H.-Schf., Wanz. Ins., vn, 96 and 106, fig. 771. Pentatoma 

 calceolata Say, Heteropt., 8, 19. 



No. 117, Harris' Collection, <S. "Cambridge, Mass., Mr. Randall." 

 The specimen in this collection is so soiled, that if so during the 

 lifetime of Dr. Harris he could hardly have been able to recognize in 

 it either the species of Fabricius or that of Say.
