TACHYSPHEX SYRIACUS, Kohl 
Mr. Saunders in his MS. list calls this species “ heliopo- 
lites, Morice.” But I am satisfied that it is not the species 
described by me under that name from Egypt. It is far 
larger. The hairs of the face are silvery in the 9, fuscous 
or even black in the f. (In heliopolites both sexes have 
the face white-haired.) The pygidial area of the @ is 
different both in shape and sculpture (vide infra—in helio- 
polites it is tectiform, shining, and very slightly striated, 
almost smooth except for a few large but ill-defined 
punctures). The ff quite agree with specimens from 
Egypt which were determined for me as syriacus by the 
author, and so I venture to call it. (In rubbed specimens 
only two bands of silvery hairs appear on the abdomen, 
and Kohl’s original description gives this as a character of 
his species. But others in better condition show 3 or even 
4 complete silvery bands in a good light. They are best 
seen by looking at the specimen from in front.) 
As I am not aware that the 2? has yet been described, I 
give a diagnosis of its characters.
