Ce$_{5}$Rh$_4$Sn$_{10}$ is known as an heavy-fermion antiferromagnet with temperature of magnetic ordering $T_{N2}=$4.3 K. We report a new antiferromagnetic phase transition at $T_{N1}=1.4$ K. In the series of Ce$_{1-x}$La$_{x}$Rh$_4$Sn$_{10}$ compounds both magnetic phase transitions at $T_{N1}$ and $T_{N2}$ shift towards lower temperatures. For Ce$_{3}$La$_2$Rh$_4$Sn$_{10}$ and Ce$_{3.5}$La$_{1.5}$Rh$_4$Sn$_{10}$ we found the only one transition. In the temperature region $T_{N1}
