This is the species which has been classed. in the National Museum 

 as belonging to Walker's Caloptenus scripius, and is tlieretore prob 

 ably the species so named by Cockerell ' as coining" from ('olorado. It 

 is, however, not that si)ecies, a female si)eciinen of the present species 

 having at my recjuest been compared with tlie types In* Mr. S. llenshaw 

 during a recent visit in London. As compared with this, he finds the 

 true svripiuH to be " much larger, heavier, and with shorter, heavier, 

 and more clumsy i)rosternal spine; thoracic carinae, especially the 

 median, shai])er and more prominent; cui>s of upper valves ot ovii)osit()r 

 much deeper; lower valves much heavier.*' He also compared this 

 with the ty[)e of Walker's Caloptenus hilifuratu.s and found it the same, 

 "agreein<i^ as to front, eyes, thoracic carinae, prosternal spine, and 

 mesost' ^bes.'' 



"'hii^ /aries somewhat, and runs very close indeed to ^l.tttUntis: 



VL e northern examples from British Coluinbia and Wash 



in, those from Nevada; and were it not for the considera 



bleu 1 f Nevada specimens, in which the male erci are alwiiys 



relati , and slender, and their marked distincw.on from Utah 



specin M. athoiis, I should have hesitated to regard the species as 



di!:tint ^ Ji. rt</««t.s', especially in view of the great variation in tlie 

 latter s^ «. As it is, I have been in much doubt where to pla<e 

 females fi *ritish Columbia and Washington, where the two si)ecit'S 

 occur toge
