Clerus quadriguttatus Oliv. 



A jet-black beetle only }{ inch long and with silvery white markings on the wing 

 covers, occurs in midsummer on pines. 



This, one of our smaller beneficial species, is only 

 ^_^, inch in Icni^^th. The head, thorax and posterior por- 

 tions of the wins^' covers are jet-black except for transverse, 

 silvery white markings on the latter; the basal [)ortion of 

 the winy covers is reddish. This little beetle occurs rather 

 commonly on hard and [jrobabh' other pines infested by 

 Tomicus or other borers, on which it undoubtedly preys. 

 Adults were taken from the latter part of June throughout
