The spination and lamellation of the limlxs is more irregular 

 in this insect than would be expected from Redtenbacher 's 

 figure. The specimen before us is slightly smaller, but agrees 

 closely with the t3q^e. The pair of long sharp spines at the 

 caudal margin of the pronotum arc^ conspicuous.
