Common and widely distributed from northern Canada to south- 

 ern Mexico. The typical tridigmuti, of which the luridus Dallas is 

 a strict synonym, is the more northern form, with prominent hut 

 rounded humeri and with the apical two joints of the antennre, 

 excej)t at their base, black. In this form the ventral row of black 

 spots is well developed, at least in all the specimens I have recently 

 examined. 



Vai'. pyrrhocerns H. S. ? I have placed under this name the form 

 with the humeri more produced, either acute or spinose, and the 

 anteiimie v^eiy little if at all darker on their apical two joints. In 

 this form the ventral row of black spcjts is frequently reduced to a 

 slender longitudinal line on the sixth ventral segment. It is more 

 common to the soutii, where it seems to replace the other form. 



Eu»i<fhistiiN variolar! IIS ?. 6. 



Inhabits almost the whole of the United States and Canada, and 

 is especially abundant in the northern States. In this species the 

 humeri vary from subacute to spinose; the apical two joints of the 

 an ten me are black, with the base of at least the fourth pale; the 

 aj)ex of the scutellum is usually slender, with the extreme tip pale, 

 and the genital segment of the male has a rather large blackish spot 

 near its base. Yvom figsUh and servus it can be distinguished by its 

 slightly smaller size and tlie absence of black points at the incisures 

 on the edge of the abdomen. This is the typical "stinck-bug" or 

 " berry-bug" of the northeastern United States. 



? Euschi!<itiis jugalis Pmv. 



I have no knowledge of this species, except the description given 

 by Provancher, but judging from that I would be very much 

 inclined to consider it a not fully developed example of fissUis or 

 variolarius. When not well hardened the juices are apt to settle 

 under the pronotum forming a black spot or band there. The type 

 was taken at Vancouver. 

 EuNCIiistiis ictericiis Linn. 



Found in the northern States and Canada across the whole width 

 of the continent. It is generally to be found on sedges in swampy
