2. Ptilocera smaxagdina Walk. 1849. 



I think that Osten Sacken's specimens are identical with these. 



3. Rosapha bicolor Big. 1877. 



An endemic and very characteristic species. 



4. Negritomyia maculipennis Macq. 1849. 



A common species, widely spread over the Malayan Archipel- 

 ago and New Guinea. 



5. Microclirysa flaviventris Wied. 1824. 



Common throughout the whole Oriental Eegion, and found 

 also in New Guinea. 



6. Solva flavipes Dol. 1858. 



Described from Amboina and recorded also from New Guinea^ 

 In our specimens the antennae are yellow at the base, and the 

 dark abdominal spots are almost fused together, forming a 

 longitudinal stripe. 



7. Solva vittipes nom. nov. (vittata DoL, 1858, not of Walker, 



1837.) 

 Very distinct by the black longitudinal stripe on the underside 

 of the hind femora. The abdomen is sometimes entirely black. 

 The wings are wholly hyaline, not infuscated at the tip; the 

 coxae, however, are yellow, and the stripe of the femora is com- 

 plete, differing therefore from the recently described S. javana 

 Meij. of Java. 



8. Chrysops signifer Walk. 1861. 



Previously known from Batchian and Borneo. 



9. Tabanus rubidus Wied. 1821. 



Recorded from India, Java, and Sumatra. The single speci- 

 men examined shows the pattern of the abdomen as described 

 by Schiner for his T. manilensis; but in regard to the form of 

 the frontal callus, I think that Ricardo is right in considering 

 the latter species as synonjmious with the following. 



10. Tabanus striatus Fabr. 1794. 



Common over all the Oriental Region. Both sexes are rep- 

 resented in the collection, the males being the more numerous. 



11. Chrysopilus ferruginosus Wied. 1879. 



A common oriental species. Our specimens correspond very 

 well with others formerly received from Formosa.
