They are Chlamisus rugvsus Zhou et T'an, sp. nov. , C. wuyiensis Zhou et T'an, sp. nov. , zyxwv C. flavomaculatus T'an et Zhou , sp. nov. and zyxwvu C. speciosus T'an et Zhou , sp. nov. . For each of the new species, illustrations of dorsal view of zyxwvu body, pygidium and the patterns of tubercles and ridges on ely- tra are given. All the type specimens are kept in the Institute of Zoology, Academia Sinica. Key words Coleoptera , Eumolpidae , Chlamisinae , Chlamisus, new species In this paper, 4 beetle species of Chlamisus Rafinesque of Eumolpidae from Fujian Province, China, are described as new to science. All the type specimens are kept in the In- stitute of Zoology , Academia Sinica. CMurnisus rugosus Zhou et T'an, sp. nov. (Fig. 1) Black, elytra with slight cupreous sheen. Head normally marked by two reddish spots which may reduce in size or even totally disappear, or expand to the whole face except for the central black spot. Labrum and antennae red brown or yellow brown, the outer side of the 1st antenna1 segment darkly patched. Near the middle of the anterior margin of prono- tum there are two reddish spots which meet each other internally in some case. All tarsi red brown. Most part of femora and the apex of tibiae of fore and middle legs red brown, the rest of the tibiae black; hind legs with most part of femur and tibia black, the apex of tibia red brown. Head finely and densely punctured, pubescence not distinct except near the lateral mar- gins of labrum, where minute pale hairs relatively long. The 1st segment of antennae ro- bust, stick-shaped; 2nd small; 3rd and 4th slender; 5-10th serrate; the apical one elongate- ly elliptical. pronotum sparsely punctured , lateral parts rugosissimus with silky tinge; in the middle a very high and large tubercle engraved by a broad longitudinal furrow on its apex, the furrow well defined by a longitudinal ridge on each side; the posterior end of the ridge bent ectally, more or less U-formed; on the posterior part of the large median tubercle, near the apex, a small tubercle followed caudally by a short furrow on each side of the mid- dle line. Scutellum trapezoid , posterolateral angles protruding posteriorly , the posterior margin arced. Elytra loosely and irregularly distributed with minute punctures , carinal ridges incomplete and partly disappeared. The arrangement of tubercles and fidges of elytra as shown in Fig. 1B. Sutural ridge, the innermost one, not obvious and replaced by three
