 apices soinetinies with an indeterminate black putcli ; the 

 autennaj in one specimen luseo-uimulate. Head slightly 

 produced anteriorly, the labrum transverse ; eyes very 

 large aud subcontiguous in (J, narrowly separated in ? ; 

 antenuic slender, joint 11a little longer than 10. Pro- 

 thorax about as wide as the head in (^, longer than broad,
