We estimate the dust extinction laws in two intermediate redshift galaxies .
The dust in the lens galaxy of LBQS 1009–0252 , which has an estimated lens redshift of z _ { l } \simeq 0.88 , appears to be similar to that of the SMC with no significant feature at 2175Å .
Only if the lens galaxy is at a redshift of z _ { l } \simeq 0.3 , completely inconsistent with the galaxy colors , luminosity or location on the fundamental plane , can the data be fit with a normal Galactic extinction curve .
The dust in the z _ { l } = 0.68 lens galaxy for B 0218+357 , whose reddened image lies behind a molecular cloud , requires a very flat ultraviolet extinction curve with ( formally ) R _ { V } = 12 \pm 2 .
Both lens systems seem to have unusual extinction curves by Galactic standards .
