In this species the basis of the markings may be regarded as four 

 spots, one subhumeral, one subsutural near the middle, one submar- 

 ginal behind the middle and one subapical. There is also a sutural 

 stripe, more or less developed. 



In the true siniiata the spots unite to form a vitta arcuately sinuate 

 posteriorly. Sometimes the union is incomplete, the apical spot be- 

 ing separated {amcricana Cr. ). The sutural stripe is narrow and 

 reaches nearly to the apex. The color is quite reddish. All the 

 specimens I have seen are from New Mexico. 



In the variety spuria Lee, the subhumeral spot is usually separate 

 and the three posterior spots are wholly or partly united, forming an 

 arcuate spot as in pare/itfiesis. The subhumeral spot, however, may 

 also be united, in which case we have the form called complex by 

 Casey. I include under spuria Lee, also oregoncnsis, differing only by 

 the absence of discal thoracic lines, a character instable in a preceding 

 species. In spuria Lee, the sutural stripe is a short broad mark sur- 

 rounding the scutellum as in parenthesis. The color is paler than 

 in si/iuata. The home of this variety is in Vancouver, Oregon, and 

 Washington, but I have a specimen collected by Mr. Warren Knaus in 

 Kansas, which could be placed here. 



In the variety trivittafa the vitta of sinuaia is almost reproduced, 

 but I have seen no specimens in which the vitta is broken by the sepa- 

 ration of the apical spot and the sinuation in the vitta is less marked, 

 so that, as Major Casey says, the design is very much like that of Para- 

 ncemia vitfigera. The sutural stripe is usually very long, but it is some- 

 times a short scutellar blotch as in the preceding variety which makes 

 the form called crotclii by Casey. The color is comparatively pale in 

 this variety. Its home is in California. It is probable xSxzX fa Itinera Cr. , 

 differing only by the absence of discal thoracic lines, is to be included 

 here in which cases Crotch's name must be used ; but I have seen no 

 specimens from the locality named by him (Slave Lake, Hudson's Bay) 

 and I prefer to leave this name in doubt for the present. 



In the variety called spuria in Major Casey's paper (but which is 

 really nameless for, as I read the descriptions, spuria is preoccupied) 

 the four spots are entirely separated, or the two middle spots may be 

 united, or some of the spots may be lacking. The sutural stripe is 

 usually short and narrow. The color is yellow, or reddish-yellow in 

 specimens from New Mexico. I have specimens from Utah, Colo- 

 rado, Kansas, New Mexico, Nevada, Dakota, Idaho and Wyoming
