This and the three succeeding genera belong to a group, Apli- 

 tlioiuc of the Halt id iii, having the form oval; antenna? 11-jointed; 

 front coxal cavities open behind ; thorax without trace of basal im- 

 pressions; hind tibia 1 grooved, at least near the apex, and ter- 

 minated by a rather long spur; hind tarsi with last joint not in- 

 flated, the claws simple. The members of the genus Lottuifiirxus are 

 very small oval or oblong convex species, usually uniform dull yel- 

 low, brownish or piceous in hue, with the elytral punctures much 

 confused; tarsi slender, the first joint of the hind pair nearly or 

 fully half the length of tibia 1 and as long as all the following joints 

 united. The following species have been taken in the State:
