This species, by the structure of the pronotal angles, is 

 allied to P. tauriformis described above ; it difFers, however, 

 not only in the uniform brownish-ochraceous hue, but also 

 in having the head and pronotum longer and the apex of the 

 scutellum more deeply sulcate. It is also apparently allied 

 to the Philippine species P. bovillus, Stal ; but the different 

 punctuation of the pronotu»v. and the colour of the head, an- 

 tenna}, &c. are sufficient to distinguish it from the description 

 of that species.

 The type was from Malacca. I possess a specimen from 

 the adjoining province of Perak.

I now possess several examples of this species from Assam, 

 the habitat from which it was described. It belongs to the 

 genus Mattiphus. All ray specimens are broader tlian the 

 one figured by Herrich-Schaffer, and the beautifully bright 

 coloration is seldom retained, though one of my specimens is 

 perfect in that respect and exactly resembles the figure. Stal 

 had not seen, but only recorded the species.
