STRANGALIA Serville. 

 The torni is elongate in all the species of Sinxngalia, very 

 niarkedly in all but sexnotata, and the last ventral segment of the 

 male is excavated, strongly in all but the last two. The poriferous 

 system of the antennae is lacking in delicata, but is present in the 

 others, and is contained in small, oval, depressed spaces, situated 

 near the tip of the sixth and following joints. The following syn- 

 opsis is copied from Dr. LeConte's of i§73, with delicata the only 

 new species since f(^und, interpolated. It will be noted that the 

 generic characters become weaker in the last .species. There is far 

 less variation in color in this genus than in Acmceops.
