THE CANADIAN ENTOMOLOGIST. 109 



\^. floridana Csy. — Can be distinguished by the strongly-dilated 

 abdomen and the very long antenna! joint. I have only one male before 

 me, from Enterprise in Florida; it makes the impression of belonging to a 

 good species, possibly from the Central American fauna. 



15. bockiafia Csy. — Can be distinguished from nigrella Lee. by the 

 presence of two foveolse in the transverse basal impression of the prothorax, 

 and by the absence of punctuation in the transverse impressions of the 

 first three tergites. Of this form I have only males before me, one each 

 from Arkansas (Little Rock) ; Tennessee (Nashville), and Texas (Vaco). 

 Casey does not mention the sex of the type, which is from Missouri (St. 

 Louis). 



16. ijianitohœ Csy. — Unknown to me; possibly a more northern 

 form of bockia?ia Csy. 



17. brevicornis^ Csy. — A specimen in my cabinet (collected by 

 Wickham, and labelled ''brevicoriiis"), from British Columbia, makes the 

 impression of being a good species ; it has the prothorax bifoveolate at 

 base, and can be recognized by the rather short antennae and the pale colour. 



18. incrassata Csy. — Five specimens from Montana (Kalispell) in 

 my collection make the impression of a good species, recognizable by the 

 long antennae and the unusually long third antennal joint. 



19. leviventris Csy. — Is a close relative oï i?icrassata, and may prove 

 to be conspecific with the latter. I have seen nine specimens from the 

 type locality (Ojai Valley in California), they have shorter antennae than 

 my specimens of incrassata, but do not seem to present other characters 

 of specific value. 



20. oregofia Csy. — A synonym oï heletiœ Csy. (vide Casey, Mem. Col., 

 II, 191 1, 167). 



21. impressiceps, Csy. — Unknown to me, possibly a synonym of 

 laticollis Csy. 



22. curtipennis Csy.; 23. abduce?is Csy.; 24. shastana Csy.; are, I 

 believe, synonyms of harfordi Csy. I have specimens from British 

 Columbia (Duncans), Washington (Baring) and California (Cole) before 

 me, which, after careful study, must be referred to harfordi Csy., yet 

 exhibit some slight differences in the general form of the body and in the 

 length of the elytra. 



25. majuscida Csy. — Unknown to me ; perhaps a synonym of 

 laticollis Csy. 



26. sparsella Csy.; 27. elsifiorica Csy.; 28. tra?isversa Csy.; 29. 

 mollis Csy.; 2,0. pitnaiis Csy., and 31. citrina Csy., are all synonyms oi lati- 

 collis Csy. My large series of Southern Californian specimens, while showing
