182 THAUMASTOPEUS SHANGAICUS. 



The elytra almost parallel or slightly narrowed posteriorly , 

 rounded at the apex , the apical callus strongly developed ; 

 smooth on the disk , with the aid of a magnifying-glass 

 only, some rows of punctures may be seen ; along the outer 

 margin and between the suture and the apical callus finely 

 strigose. 



Pygidium closely and finely strigose. 



The mesosternal process slender, nearly straight, the top 

 slightly incurved. 



The undersurface with a few scattered large but shallow 

 punctures; the thighs of the forelegs clothed with black 

 hairs; the anterior tibiae with two teeth before the termi- 

 nal one. 



I found two male specimens of this species in Chevrolat's 

 collection, labelled » Shanghai, Bowriug"; Wallace has also 

 enumerated examples of the same locality among Th. pullus 

 Billb., and he rightly remarks »The Hongkong specimens 

 are very fine and glossy , with the punctuation of the elytra 

 almost entirely wanting." 



Although very closely allied to Th. pullus Billb., Th. an- 

 thracina Wied. and Th. cupripres Waterh., this species differs 

 from all these by its slender form , short thorax and strong 

 apical callus; moreover pullus has the elytra rather deeply 

 punctate-striate , and cupripres is at once distinguished by 

 the peculiar semicircular deep striae between the apical 

 callus and the suture. I may still add that the forceps of 

 Shangaicus differs largely from that of the allied species.
