Indian forest insects of economic importance Coleoptera . iv, 68 (1897). Habitat.—Calcutta, Dehra Dun, Darrang, Assam. Also reported fromMurshidabad, Sikkim, Shillong, and Andaman Islands. Trees Attacked.—Spondias mangiferae : Calcutta (C. O. Bateman), DehraDun (jjiihi) ; Ficus elastica : Charduar, Assam. FAMILY CHRYSOMELIDAE -59 Beetle.—Oblong, thick-set. Head, prothorax, antennae, and legsshining ; eyes canary-yellow, and mouth parts black ; elytra a bright salmon-pink in colour, each with eight spots,Description. the upper and lower ones of which coalesce when the elytra are closed, and thus give fourteen spots. Beneath the basal median spot is a large roundor square one on each elytron, another large one beneath this, andthen the large apical one. On the outer margin of each elytronare four smaller spots placed more or less equidistantly from oneanother. These spots sometimes coalesce to form transversebands. Under-surface of abdomen canary-yellow, darker onthoracic region. Length, 13 mm. to 17 mm. ; breadth, 7 mm. FIG. 183. Podontia i^-punctata,Linn. United Pro- Larva.—Dirty yellow or yellow-brown, the body thick andcorrugated. The grub is thick, soft, and fleshy, and has a black shining head, a black patch on dorsal side of prothorax, and three pairs of black shining , 16 mm. The larva covers its body with its own excrement, and so has the appearanceof the droppings of a bird, and is thus able to escape the attacks of foes. Cocoon and Pupa.—The grub pupates in a coarse earthen cocoon in the soil. Thiscocoon resembles in size and shape a hazel-nut. In October 1895 Mr. C. O. Bateman of the Indian Museum, Calcutta,presented specimens of this insect in all stages of larva, Life History. pupa, and imago to the museum, with the informationthat the insect stripped the leaves from a Spojidias mangiferae tree in his compound in Calcutta. Mr. Bateman stated that thebeetles appeared almost every year when the tree was in full foliag
