This genus and the next four are grouped by LeConte under 

 the name Phofiui. All five genera have the head covered by the 

 hood-like thorax. The elytra vary in color, but in all our species 

 without ^^■ell developed light organs they are black. Of the group 

 he says: "There are in many families of Coleoptera strong resem- 

 blances between species of different genera, but I Imow of none 

 more deceptive than those presented by this group of Phofini. The 

 inexperienced student should, therefore, always ascertain the genus 

 to which his specimen belongs before attempting its specific deter- 

 mination." The genus Lucidofa is easily known 1)y the very 

 broadly compressed antenna^ which are not serrate, but graduall>- 

 narrowed externally, with the second joint very short and trans- 

 verse. The light organs are feebl>- devehtped and indicated by yel 

 low spots on the last ventral of the female or last two ventrals of 

 male. The two species belonging to it are diurnal and fropienl 

 shady places.
