Biotoay: The only information on the biology of this species 
consists of the following host-plant records taken from the material 
examined: ‘‘On Cuscuta sp.,’’ Berwyn, Md., July 20 (USNM); ‘‘on 
blue weed and dodder,” El Paso, Tex., July 8 (DMA). 
Discussion: This species, with its small size, black color, white 
scales, and ‘‘pebbled”’ prothorax is not easily confused with any other 
species in the S. sculpticollis group, except S. seriatus LeConte. ‘The 
differences between S. apionides and S. seriatus LeConte are given in 
the discussion of S. seriatus. 
DistRIBUTION: Present records indicate that the range of S. 
apionides includes the Atlantic and Gulf coastal plains and the south- 
ern and middle Appalachian highlands; a single record (El Paso) 
indicates the presence of this species in the basin and range portion 
of Texas. The following specimens were examined:
