For a description of this species see tliat of sulcatfia Meinert. 



I'nderwood in his synopsis of the species of this genus has regarded 

 millM-rti, aspcripcti, and siilcatits as valid species, but it seems to niethat 

 they are all identical with lti/aliini.<<. I have examined a large amount 

 of material from nine ditfereiit States and have been able to tiiid only 

 one species.

A recent examination of the type of Cryptopn po-Htiva Say, which is de- 

 posited in the British museum, by Mr. Iv. Innes Pocock,* has proven 

 that Newjunt was mistaken as to Say's spe<*ies having eyes. The 

 elimination of this (character makes Theatops identical with Opin- 

 thetneya; but as the former is oldest it must be used in place of the lat- 

 ter, notwithstanding the fact that it is based in part upon an erroneous 

 character. This conclusion was publislied by me some time before Mr. 

 Poiock's i)ai)er api)eared (T. craHsipes Bollman, Am. X. Y. Lye. N. H., 

 110, 1888; T. spinicaudus Boll., Eut. Amer., 6, 1888).
