﻿COLEOPTERA COLLECTED ON THE BORDERS OP TIBET. 213 



the eyes ; frontal farrows faintly impressed, flexuous ; antennae nearly half 

 the length of the body. Thorax as long as broad, gradually and slightly 

 narrowed behind to the apex of the nearly rectangular angles ; lateral rim 

 accompanied by a sharply incised furrow ; basal foveee sharply impressed, 

 two on each side, the inner one long, the outer very short and communicating 

 with the inner one by a short basal furrow. Elytra elongated, rounded at 

 the shoulders, obliquely sinuated at apex, broadest far behind the middle, 

 deeply striated ; scutellar stride null, except a short oblique incision close to 

 the basal fold ; interstices moderately convex, much narrowed near the apex, 

 and the 9th narrow throughout ; one dorsal puncture only on the 3rd inter- 

 stice far behind the middle ; the 8th stria regularly ocellate-punctate. 

 Beneath nearly smooth. $■ . Terminal ventral segment with a central sharp 

 carina strongly elevated in the middle. Long. 23 — 26 millim. $ , $ . 



Wa-shan. A large series of examples. The species, like 

 P. simillimus (Fairm.), is allied to the European P. melas, but it 

 is a much larger insect than either, and the thorax is differently 

 shaped. The palpi in the male are somewhat dilated, especially 

 the labials, and truncated at the apex. The middle episterna are 

 short and broad. 



Trigonotoma dohrnii, Chandoir. 



Ichang. A species of South-eastern China, found at Hong 

 Kong, and also at Saigon in Cambodia. 



DOLICHUS FLAVICORNIS, Fllbr. 



Wa-shan. Found in the warmer temperate latitudes through- 

 out Europe and Asia. 



COLPODES AM03NUS, ClldUcloir. 



Wa-shan. A widely distributed East Asiatic species. C. su- 

 perlita, Bates (Proc. Zool. Soc. 1888, p. 383), from Kiu Kiang, 

 is probably only a variety, in which the produced apex of elytra 

 is truncated and spined at the sutural angle ; the thorax is, how- 

 ever, a little shorter and more sinuated behind. The single 

 example from Wa-shan is nearly intermediate between the two 

 forms. 



Family COPBIDvE, 



Synapsis davidis, Fairmaire, Ann. Soc. Ent. Fr. 1878, p. 96, 



pi. 14, f. 5. 

 Wa-shan. Originally taken by Pere David in " Central 

 China." The species is very distinct from the Indian forms pre- 

 viously described, by its subopaque and finely reticulated elytra, 

 in which the striae are scarcely visible. 



Enoplotrupes sinensis, Lucas. 

 Wa-shan, alt. C000 feet. Taken by Pere David in the district 

 of Moupin, Eastern Tibet. 



Enoplotrupes variicolor, Fairmaire. 

 Wa-shan, alt. 6000 feet. Recorded by Fairmaire as taken in 

 the interior of China. 



(To be concluded.)
