There is a prominent l)lack scutellum developed on the first segment, measuring a])out mm. in length x .3 mm. wide. The caudal segment is somewhat rugose, and is pale brown shading to olive-brown on its anterior half. Abdomen concolorous with body. Legs, pale brown. Prolegs concolorous with body, the claspers black. Spiracles oval, large, conspicuous, and Ijlackish brown. Head, pale l)rown, sparingly covered with short yellowish- brown hairs. The surface is finely granular. The segmental lines separating lobes and clypeus are slightly lighter in color than the contiguous parts. Ocelli, minute, dark brown. Mouth parts, dark brown, par- ticularly the mandil)les which shade into blackish-brown. The head is small in comparison with the body, measuring about 3 mm. from crest to mouth, and about mm. from side to side. The entire body of the caterpillar is covered with minute brownish pile, discernible only with a lens. A pair of these hairs on the dorsum of each segment are much elongated, and a num- ber of hairs are particularly well developed and thickened over the caudal segment. See Plate PLATE 29 Mature larva of Megathymiis stephensi enlarged x ]%. Photo by Menke As the larva reaches maturity it produces, in some unknown manner, a soa})v or fiakv white material, composed of small white platelets, resembling pads of silk, with which it lines the interior of the burrow, and also covers itself. At this period it rests in the lower portion of the burrow with its head toward the opening. Ptipation occurs at this site. The larvae are heavilv parasitized by Apaiitclcs iiirc/atlixnii. 85.
