Coleoptera from Hainan Island^ China. 311 



part almost smooth ; the vertex, the lateral ridges (which are 

 strongly marked and converge considerably anteriorly), and 

 the extreme front margin black. Thorax bhick, narrowly 

 bordered with green, the middle with scarcely any punctua- 

 tion, the sides linely and rather closely punctured but shining. 

 Scutellum green, with two black spots, or almost entirely 

 black. Elytra very much flattened^ rather tinely punc- 

 tured, the punctures having a tendency to form lines, the 

 sides almost smooth, with a iew transverse rugai on the 

 outside of the apical callosity. Pygidium not very closely 

 punctured. Anterior femora red above, with a slight projec- 

 tion on the anterior margin near the apex. Tibiae subparallel, 

 with a slight dilatation near the base posteriorly, and with 

 numerous tubercles on the posterior surface. Middle femora 

 red above. Posterior femora with a red spot. Posterior 

 coxse and apex of abdomen red. 



$ . — Lateral ridges on tlie head nearly parallel ; front of 

 the clypeus broadly black and coarsely rugose. Thorax with 

 the middle distinctly and moderately thickly punctured. 

 Pygidium with the punctures more asperate. Anterior femora 

 with the subapical jjrojection less prominent ; tibiae broad, 

 with a broad triangular tooth on the outer edge, not tuber- 

 culate posteriorly. 



Tceniodera Wki'teheadi, sp. n. 



Statura T. ornatce ; nigra, opaca, supra plaoiuscula ; thorace sat 

 rugose, flavo trivittato, vitta mediana abbreviata ; scutello vitta 

 flava ornato ; elytris rubris, tlavo-maculatis, sutura usque post 

 medium sat late nigra ; pygidio rugose, nitido, macula basali 

 triangulari flava. 5 . 



Long, ly mm. 



This species is very close to T. ornata, Saund. It differs 

 in having the sides of the thorax more parallel posteriorly, so 

 that the hind angles are less rounded ; the median yellow 

 vitta extends to the middle, the lateral vittse occupy the 

 greater part of the sides. The elytra are red except the 

 broad sutural patch, which extends to the second pair of 

 yellow spots. There is a yellow spot at the base inside the 

 humeral callosity. There are two quadrate spots near the 

 suture (one on each elytron), not united as in T. ornata, and 

 there are two similar spots considerably behind the middle ; 

 there is a spot at the side behind the shoulder and another 

 rather beyond the middle. The pygidium is very rugose, 

 shining, and has a broad triangular yellow patch at the base. 

 The whole of the metasternum is yellow except the middle.
