﻿NEW SPECIES OF COLEOPTERA FROM CHINA. 117 



insect is of a violaceous-cupreous colour; the thorax is very 

 finely punctured on the disc, coarsely at the sides, which latter 

 have a deep longitudinal depression at the base ; the elytra have 

 four double rows of deep punctures, with numerous finer ones 

 on the interstices. 



Phytodecta flavo-plagiata, n. sp. (PI. I. fig. 8). 



Black; the head, apical joints of the antennae, and the legs partly, 

 fulvous ; thorax finely punctured ; elytra more strongly and serni-regularly 

 punctate, black, a transverse spot on the shoulder and another near the 

 apex, flavous. Length, 2| — 3 lines. 



Of subquadrate and moderately convex shape, the head fulvous, finely 

 and rather closely punctured ; antennae not extending beyond the thorax, the 

 lower five joints fulvous, the others black, very broadly dilated; thorax 

 about three times broader than long, the sides rather strongly rounded, the 

 surface finely and rather closely punctured on the disc, the punctures of 

 various size, those at the sides much larger, the lateral margins slightly 

 thickened, smooth and fulvous, the rest of the disc black ; scutellum very 

 broad, impunctate ; elytra not broader at the base than the thorax, more 

 strongly punctured than the latter, the punctures partly arranged in rows, 

 the shoulders with a transversely-shaped flavous spot, and another one of 

 similar shape placed at the sides and at some distance from the apex ; the 

 under side and legs nearly black, the femora and tibiae more or less fulvous. 

 Easily known from its congeners by the coloration of the elytra ; the sub- 

 apical spot of the latter is generally more or less constricted at its middle. 



Four specimens. 



Melasoma maculicollis, n. sp. (PI. I., fig. 9.) 



Metallic violaceous blue ; thorax flavous, finely punctured with five 

 spots, placed transversely ; elytra semi -regularly punctured, longitudinally 

 impressed below the shoulder ; sides of abdomen fulvous, spotted with 

 black. Length, 5 — 6 lines. 



Head finely punctured at the sides ; antennae not extending beyond the 

 thorax, the terminal joints gradually thickened, black, the basal four joints 

 more or less fulvous below ; thorax narrowly transverse, the anterior 

 margin concave at the middle, the sides strongly rounded anteriorly, the 

 surface very finely punctured, flavous, with five black spots, a small one at 

 each side, another at the middle of the base, and two large spots at the 

 middle of the disc ; scutellum black ; elytra broader than the thorax, 

 metallic dark blue, rather closely and finely punctured, the punctures 

 arranged partly in single or double rows ; a short distinctly raised costa is 

 seen in front of the shoulder near the base (female), which in the male 

 insect is replaced by a longitudinal smooth space ; the shoulders are 

 prominent and swollen ; the underside and legs are metallic blackish blue, 

 but the sides of the abdomen are bright flavous, each segment having a 

 black spot at the sides, the last segment with two central spots. 



Of this large and handsome species several specimens were 

 obtained ; the elytral short costa in the female is very peculiar, 

 and is followed at the sides below the shoulder by a short longi- 

 tudinal groove, visible in both sexes. 



Phyllodecta multipunctata, n. sp. 

 Metallic dark blue ; the head and thorax closely punctured, elytra 

 deeply punctate-striate, the strise rather irregular, the interstices finely
