Types in Berlin Museum. 



The types of this species J have seen in IJerlin. Westwood's type 

 of Sd€roc}ermatlioracwa\» labeled "Carolina, Zimmermann" while it is 

 accompanied by another specimen bearing label "Baltimore, Md." 

 King's type of Pi-istocera atni is in good condition. As suggested by 

 Prof. Westwood, these insects are sexes of a single species. It is the 

 largest species known, and the male miglit easily be mistaken for a 

 Tiphiid, My collection ccmtains specimens compared with the types 

 iu Berlin. I have seen specimens from various parts of the country, 

 the $ not being rare. The 9 is extremely rare. The National Museum 

 contains <a single 9 specimen collected by Mr. E. A. Schwarz, under
