sembles Sclciodermus in its biology, as nijoht be expeerod 

 from its relationship to that genus. 



So far as ^\c have knowledge of the habits of the Bcthyli- 

 dae Ave may group them in three groups: 



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

 fossorial in habits, feeds on sweets as well as upon the juices 

 of the prey, and lays but a single egg per host. The habits of 

 Epyrls e.rtraiu'us Bridwell have been worked out by Dr. F. 

 X. Williams, the writer has observed fossorial habits in a 

 South African species, and Williams and the author have 

 observed Holepyris hairaiiensis, and Silvestri, an Italian spe- 

 cies- of this genus. 



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

 cealed Lepidopterous larvae and lays several eggs upon them 

 without uioving them. These species require saccharine food. 

 Several species of (lon'wzns, Perisierola. and Sierola are 

 known to attack in this manner. LaeliKs also ap})arently be- 

 longs with these. 



(3) The ScJcrodo-iniis 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 

 l)rey.

Nesepyris new genus. 



Head parallel sided, elongate oblong, greatly prolonged behind the 

 eyes; eyes slightly hairy, ovate; mandibles nearly straight, crossed in 

 repose, bidentate within before the acute apical tooth ; antennae 13- 

 jointed ; ocelli in an acute triangle. 



Pronotum not margined nor furrowed, as long as the mesonotunt 

 and scutellum together; mesonotum transverse, lateral furrows abbrevi 

 ated in front, parapsidal furrows percurrent ; scutellum with oblique 

 lateral fossae at base connected by a shallower impressed line : propo- 

 deum margined laterally and behind, with an imperfect median raised 

 line; calcaria 1-1-2; ungues simple; posterior tibiae with a few denticles 

 outwardly; wings with closed costal, median and submedian cells; 

 nervulus interstitial with the basal ; stigma very short and poorly
