the tergite, apex terminated by three spines; sternite with converging 

 lateral borders, rounded posterior angles and emarginate posterior 

 border; legs long and slender, with cylindrical segments, femur very 

 feebly spined, 1 at the apex internally, 1 in the posterior half 

 of the internal surface, 1 in the anterior half of the under-inner 

 edge and 1 in the corresponding spot on the under outer edge, 

 tarsi unarmed, claw with two spurs.

 spines; i th to the 18 th pairs with two 1 st tarsal spines; 19 th and

This fine and interesting species resembles the preceding B. cari- 

 nulata in having carinate and denticulate tergites, but differs from it 

 in having fewer antennal segments, more prosternai teeth, differently 

 spined pleurae and longer and more sparsely spined anal legs. 



Otocryptops. 



16. Otocryptops luzonicus (Kohl.). 



Celebes: Luwu. One specimen. 

 This specimen is of considerable interest since it partakes of the 

 characters of the two varieties of this species — namely celebensis 

 and australis — which Dr. H aase established. The first of these was 

 from N. Celebes; the second from New Guinea and Halmahera. But 

 since this specimen from Luwu is intermediate between the two va- 

 rieties, they can scarcely receive any longer the rank that was ori- 

 ginally assigned to them. 



Cryptops. 



17. Cryptops ruficeps sp. n. PI. XIX, fig. 7. 



Sumatra: Singkarah, A single mutilated specimen. 



Colour olivaceo-fuscous , head, antennae and anal segment pale 

 chestnut. 



Head-plate ovate, without sulci, overlapped behind by the first 

 tergite. Antennas short composed of 17 segments. Maxillary coxce 

 wider than long, with its anterior border wide and nearly straight, 

 furnished on each side with a single seta, maxillary feet rather slen- 

 der, furnished with three internal setae, claw long slender and cur-
