12. Chrysopilus correctus 0. S. 1882. 

 A very distinct endemic species. 



13. Laphria dimidiata Macq. 1846. 



Widely spread over the Malayan Archipelago. 



14. Philodicus longipes Schin. 1868. 



An endemic species. I think it very probable that Erax 

 integer Macq., 1846, is the same species. 



15. Ommatius chinensis Fabr. 1794. 



This is 0. fulvidus of Osten Sacken's paper, a common species 

 in the Oriental Region. 



16.. Emphysomera aliena 0. S. 1882. 

 An endemic species. 



17. Systrophus sphecoides Walk. 1860. 



We have a single specimen which corresponds well enough 

 with the description of this species. Previously known only 

 from Celebes and Macassar. 



Thorax entirely black, with a yellow vertical stripe from the 

 humeri to the front coxae which are black ; metasternum distinctly 

 bluish, with many transverse furrows. Front legs almost en- 

 tirely yellow, only the femora brownish below, and the last 

 tarsal joints dark. 



18. Agonosoma vittatum Wied. 1819. 



A beautiful species, widely spread over the Oriental Region. 



19. Paragus serratus Fab. 1805. 



Common in the Oriental (and also in the Ethiopian) Region, 

 and also known from Formosa. 



20. Melanostoma planifacies Macq. 1848. 



A true Melanostoma, very distinct by the form of the face 

 as described by de Meijere. Previously known only from Java. 

 The previously unknown male has the abdomen entirely yellow, 

 with very narrow black lines at the hind margins of the seg- 

 ments ; genitalia of greater size, black, placed asymmetrically, the 

 strong yellow penis prominent below. Legs entirely yellow. 



21. Asarcina segrota Fabr. 1805. 



A common oriental species, known also from Formosa. Sack 

 places it in the genus Didea, but it seems better to allow it to 

 remain in the present genus, on account of the form of the 

 oral opening, of the position of the ocelli, and of the presence
