body it is densely variegated or marbled with small, irre- 

 gular, bare spots. 



Head and scape of antennae faintly rugose by a strong 

 and rather confluent punctuation. Thorax faintly rugose , 

 a little narrower and longer than in the allied species, the 

 sides nearly straight and parallel , with scarcely any trace 

 of lateral spine. The scutellum broadly truncated at the 

 apex , the angles rounded ; the sides nearly parallel ; a tri- 

 angular smooth space on the middle along two-thirds of 

 its length. The elytra rather strongly punctured , with 

 glossy granules at the base; the apices obliquely truncate, 

 the sutural angle rounded , the outer one pointed and 

 slightly produced. Body beneath and legs finely and 

 distantly punctured ; on the sides of the metasternum some 

 faint transverse wrinkles may be observed. 



Two female specimens from Sumatra (Muller and Scha- 

 gen van Leeuwen). — The one sent over by Mr. Schagen 

 van Leeuwen has been captured at Kotta Zuydewijn near 

 Solok, and shows on the outside of the bare elytral spot 

 a similar but smaller one. 



Ohs. Since the publication (1873) of the 10th volume 

 of the » Catalogus Coleopterorum", two other species of this 

 genus have been described, viz.: 



P. vitticollis Thorns., Ann. Soc. Ent. France. 1878. 

 Bull. p. XVIIL (Rhamses) . . Borneo. 



P. rugosus C. 0. Waterh., Proc. Zool. Soc. London. 

 1884. p. 218 Timor-Laut Islands. 



Tetraglenes diuroides , n. sp. 

 (Plate 3, fig. 4). 



Length 16 mm., that of the antennae 17 mm.; width 

 of the shoulders of the elytra 2,5 mm. — Black; parts of 

 the mouth and legs pitchy brown ; subshining , covered 

 with a strong punctuation which is more or less reticulate
