The hody is rel- atively uniform in width except for the taj>ering caudal segments and the first thoracic. Head, ocelli and mouth parts, jet black, except for the edge of the glabella and the proximal joints of antennae, which are ivory white. The head is retractile and is seldom extended beyond the fleshy cowl even during the act of feeding. The cervical shield is grayish-black, mottled, and is free of pile. A narrow gray-white line bi- sects it longitudinally, and there are a number of minute Ijlack nodules scattered over its lower half. The first segment is fleshy, and is black al)0ve and dirty gray beneath. Over its surface are scattered numerous black tubercles, each one of which bears a single hair. The upper series of these hairs is l:)lack or gray, while the lower hairs are white. In the mid-dorsal area there is a longitudinal row of subovate gray large spots, one to a seg- ment, each of which is connected with its fellow anteriorly and posteriorly. The surface of this area is sparsely covered with minute black papil- lae, some of which carry minute spiculiferous PLATE .54 Larva of Strymon cali- fornica. enlarged x 4. Photo by Menke Lateral to each one of these large spots is a narrow soiled white line, which fades out as the middle of the segment is reached, and which is widest at the anterior edge of the segment. Over this line there are scattered series of prominent black papillae, each one of which bears a long black hair. The area lateral to these hairs is brown (lighter brown on the segmental junctures) as far down as the overlap. This brown area is sparsely covered with minute papillae similar to those oc- curring over the mid-dorsal area. There is a gray indistinct area al)Ove each spiracle, edged above and below with dirty white dashes. These dashes or inter- rupted lines take a triangularly d
