Abstract: Pyralidae can be distinguished from other families by the following characters: - On prothorax k group bisetore, and abdominal segments 1-8π and η on the same pinaculum (Pl. I Fig. 1 A, B). Pyralidae can be divided into 3 groups: Group 1, π group in mesothorax and metathorax bisetose, including Gallerinae Crambinae (Pl. I Fig. 3). Group 2, π group on metathorax unistore, k, η and μ of 9th abdominal segment present on the same pinaculum, including Epipirchinae Pyralinae Phyeitinae (Pl. I Fig. 4). Group 3, π group on mesothorax unistore, k and μ on 9th abdominal segment absent, including all other sub families. In Siginae, crochets uniordinal arranged in a complete circle (Pl. I Fig. 7). In Nymphalinae Scoparinae, crochets biodinal arraged in a complete circle (Pl. II Fig. 8). In Pyraustinae, crochets triordinal arranged in a mesal penellipse (Pl. II Fig. 9). Then, from the standpoint of chaetotaxy of the larvae Pyraustinae will be defined as follows: on prothorax k and π group bisitore, on the 9th abdominal segment, both of β present on the same pinaculum, η long, k and μ absent (Pl. I Fig. 6). From the habit of larvae this subfamily will be divide into two groups; one covers the borers of stems, pods and roots, the other covers the leaf-spinners or rollers. The former includes Dichocrocis punctiferalis, Omphisa phagialis, Maruca testulis, Pyrusta nubilalis and Pyrusta memnialis, the latter includes other spices. The borers group has extra pinaculum with no seta or with micro seta on the mesothorax and metathorax, presenting micro seta of ε on abdominal segments (Pl. II Fig. 12. 13). But in the leaf roller group, these are absent. Maruca testalis, and Pyrausta nubilalis belong to the intermediate of two (Pl. III Fig. 14.15). Head markings are good specific characters as shown in Pl. II 16-PI. IV Fig. 32.
