SUMMARY From the foregoing morphological descriptions of the main genera of the British Melolonthinae, it will be seen how much more closely allied Amphimallus is to Melolontha than is Serica. In nearly all details where the former species differs only slightly from Melolontha, Serica is found to differ more widely. This therefore gives support to the practice of separating this subfamily into the two tribes of Sericini and Melolonthini. Since Scarabaeid larvae other than those of the Melolonthinae are also found damaging crops in the British Isles, a table for the rough identification of the most common genera is appended. All species of the Scarabaeoidea are not however included, and since genera such as Geotrupes and Aphodius may be found at the roots of crops, confusion may occasionally arise in their identification, although they are not known to cause damage to plants. In such cases therefore reference should be made to the foregoing descriptions for exact identification.1 (2) Body club‐shaped at caudal end, antennae long with joints of unequal length. 3. 2 (1) Body thickest at middle, antennae short with joints of equal length. Cetonia.3 (4) Spines of radula arranged in two longitudinal rows 5. 4 (3) Spines of radula arranged in one transverse row Serica.5 (6) Longitudinal rows of spines on radula parallel or slightly converging at ends 7 6 (5) Longitudinal rows of spines on radula diverging especially at caudal end. Amphimallus.7 (8) Caudal aspect of mandibles with stridulating area made up of small pits. Melolontha.8 (7) Caudal aspect of mandibles with stridulating area made up of transverse file‐like ridges Phyllopertha.
