R. Zweifel June 25, 1930 Rhincbchus lemmei 2 mi W Senora Crossing, San Diego Co., Calif. June 21, 1951. 1504 R. Zweifel Whereas in number 1505 the light rings contain only red markings on the cream, on this specimen the lateral portions of the light rings are characterized by the presence of dark markings centrally in every scale. The scales of three to five central rows are mostly red (within the light ring), forming a series of square red blotches. The dark blotches are narrowed laterally, while in 1505 they are of about the same width right down to the ventrale. There are a few light centered scales laterally in each of the dark blotches, but because of the shape of the blotch, they form a triangle rather than an oval as in 1505. The ventral surface is without dark markings.
