Named Miris vagans ? Fab., by Mr. Say. The species appears 

 but little like a Miris, and it is surprising tliat so close an observer as 

 Mr. Say should confound the two genera. Although similar to the 

 European N. vagans Fab., it is, nevertheless, sufficiently distinct 

 from it. Our species is widely distributed throughout North Amer- 

 ica, and offers several varieties, particularly in the number and 

 length of the nervures of the membrane. Harris says " does not 

 seem to agree with the Swedish vagans."

 dull ochreous yellow, sometimes tinged with rosaceous. Form rather 

 elliptical; pubescent. Head ochreo-testaceous, sparingly incanous 

 pubescent, mixed with longer hairs; behind the eye a large black- 

 ish spot, and before the eye a blackish trace; tylus yellow, nar-

 flattened between the eyes, having two abbreviated fuscous lines 

 extending from the ocelli and divaricating anteriorly. Antennae tes- 

 taceous, remotely pubescent, the tip of third and the whole of the 

 fourth and fifth joints infuscated. Rostrum reaching to the inter- 

 mediate coxse, testaceous, piceous at tip. Pronotum gradually widen- 

 ing to the base, sparingly incanous pubescent; a longitudinal im- 

 pressed dark line on the middle, with impressed waved lines like 

 those of N.ferus-, the posterior lobe a little flattened above, the sides 

 emarginated before the humeri, the adjoining edge defined by a sub- 

 mirginal impressed line, the lateral carina sharply defined as far as 

 the line behind the collum. Pectus paler than the upper surface, 

 minutely pubescent; the pleurse with an interrupted blackish vitta 

 which becomes broader behind and is continued along the sides of the 

 venter; meso- and metasternum deep black. Legs pale testaceous, a

 and dotted in irregular rows with brown, not so stout as in M. dorsa- 

 lis Duf. Intermediate femora also ribbed, more sparingly dotted;
