variations in size, shape, colour and sculpture, represents undoubtedly one 

 species only, and must be referred to laticollis Csy. I have five specimens 

 of pitnalis Csy. before me (three from the author himself, two from 

 Wickham), none of them specifically difi"erent from laticollis. 



32. wickhami Csy. — Possibly a synonym oi helenœ Csy. 



33. brwinescens Csy. — Without much doubt identical with nigrella 

 Lee. I have two specimens in my collection from New York, which can 

 be referred to bnmnescens, and which I cannot separate satisfactorily 

 from nigrella. 



34. boulderoisis Csy. — Probably a synonym of helenœ Csy. 



35. oblata Csy. — Probably also a synonym ot helenœ Csy. 



36. pallidipes Csy. — Possibly a synonym of harfordi Csy. 



37. ttteana Csy. — Unknown to me. 



38. modica Csy. — Probably a synonym oi laticollis Csy. 



39. sensilis Csy. — Is experta Csy. 



40. limatula Csy. — Is a synonym of laticollis Csy.
