JACOBY O N N E W [Feb. 17, There is only a single specimen of this species before me, seems to be closely allied to C. limbellus, Mannerh., or rather to its black variety, which is almost identical in its coloration; but the sculpture of the thorax in C. limbatipennis is quite distinct from the allied and other similarly coloured species, forming elongate confluent rugosities at the sides, which will prevent the insect being mistaken for any of the allied forms. CRYPTOCEPHALUS PARTITUS, n. sp. (Plate XL fig. 8.) Cylindrical, convex ; black ; base of antennae and the legs fulvous ; anterior and lateral margins of the thorax and two spots at the base yellow; surface finely strigose; elytra regularly punctate-striate, yellow, a sutural and discoidal longitudinal band black. Length 1 line. Head flat, yellow, the extreme base and a short longitudinal central band, connected with the latter, black ; antennae nearly as long as the body, the five lower joints fulvous, the rest black, third and fourth joints equal. Thorax rather transverse, the sides very little rounded ; surface entirely covered with very fine confluent longitudinal strigee, black ; the anterior and lateral margins (the former slightly widened at the middle), and two large, closely-approached transverse spots, placed at the middle of the base, yellow. Scutellum black. Elytra strongly and regularly punctate-striate, the interior of the spots black, the sutural band widened at the base and connected at its end with the broader discoidal band in some specimens, but in others isolated ; the latter commences at the shoulder, where it is rather narrow, and after widening slightly immediately below the base, continues straight towards the apex, where it is interrupted at some distance from the latter ; the same band extends generally in width from the fifth to the ninth row of punctures, the rest of the disk of the elytra and their apices being bright yellow. Legs robust, fulvous. Underside black. Wada toge. From all other nearly similarly coloured species (C. boehmi, limbellus, lateralis) the present may be at once distinguished by the sculpture of the thorax, the close striae of which give the latter a silkv appearance, punctuation being altogether absent. In one of the specimens the yellow spots of the thorax are very small, and the two black elytral bands are almost connected anteriorly by an indistinct transverse piceous stain. CRYPTOCEPHALUS NIGROFASCIATUS, n. sp. <S. Below black ; apex of the abdomen, legs, and base of the antennee flavous; above testaceous ; thorax distinctly punctured ; elytra strongly punctate-striate, each elytron with a longitudinal black band, abbreviated behind. 2 • Larger, entirely flavous or pale fulvous. Var. a. The elytral band very obsolete, sometimes entirely absent. Var. b. Elytra black, the sutural and lateral margin flavous. |
