sembles Sclcrodcnnus in its biology, as luiglir be expected 

 from its relationship t<3 that genus. 



So far as we have knowledge of the habits of tlie Bctlivli- 

 dae Ave may group them in three groups : 



(1) The Epyris group, in which the adult is markedly 

 fdssorial in hiibits, feeds on sweets as well as upon the juices 

 of the prey, and lays ])iir a single egg per host. 'I'lic habits of 

 Epyris extraneits Bridwell have l>een worked <mt by Dr. F. 

 X. Williams, the Avrircr has observed fossorial liabits in a 

 South African species, and Williams and the author have 

 observed Hole/>yris Jian-diiciisis. ;nid Silvestri, an Italian spe- 

 cies of this genus. 



(2) The Goniozus grou}), in which the adult attacks con- 

 cealed Le])i(l()]iterous larvae and lays several eggs u])on them 

 without moving them. These species require saccharine food. 

 Several species of (jonioziis. Pprislcrola and Sierola are 

 known to attack in this manner. IjdcJiiis also apparently be- 

 longs with these. 



(3) The Sclerodermus group, in which the adults feed 

 exclusively upon the juices of their prey which they attack in 

 hiding and do not move, and several eggs may be laid upon the 

 in-ey.

Head parallfl sided, i-lnngatc ()t)lon£r, greatly prolonged behind the 

 eyes: eyes sligjitly hairy, ovale; mandibles nearly straight, crossed in
