'Three species of the lnteus group described by Norton are distinguishable by the 
color characteristics. The types are lost, with the possible exception of trivitfatus. 
Stigmatus may prove to be a good species. Mendicus and trivittatus are closely 
allied, and probably identical, the older name, mendicus, holding. Monochroma may 
prove to be a light form of mendicus. These species all fall in the table with mendi- 
cus, with which they are closely allied. Stigmatus and monochroma may be good spe- 
cies, and the original descriptions of them are appended (Nos. 47 and 48). The fol- 
lowing synopsis indicates the color differences of this group: 
Dorsum pale, except tip of scutellum, metanotum, and stripe down tergum 
9 49. stigmatus Nort. 
Dorsum with a black spot about ocelli and three on lobes of mesonotum ; body other- 
wise pale 9 39. trivitfatus Nort. 
Dorsum with two spots on mesonotum, tip of scutellum, and spots on metanotum 
black 9 39. mendicus Walsh. 
Insect altogether pale, including antenna? 9 50. monochroma Nort. 
"In this character the two following species depart in this sex from the character- 
ization of the genus.
