with much stronger sculpturing and ornamented with distinct ridges 

 separated by elongate grooves. The lateral surface smooth ; the inferior 

 keel present only on the 2 nd , 3 rd and 4 th somites. The tubercles of the 

 anal somite much larger. The caudal process less compressed, with a 

 distinct lateral tubercle. 



Lenght about 33 mm. width of 10 th somite 3.3. 



(J. Relativity more slender than in carneum (length 28, width 2). 

 The process on the sternum of the 8 th somite , more erect. Copulatory 

 foot slender, curved, dilated distally and terminating in two processes, 

 an external and an internal; the external laminate and constituting 

 a sheath for the internal, which is more slender, more cylindrical 

 and with a sigmoid flexure. 



A great number of specimens were obtained, most of them being 

 of a pale concolorous tint throughout. In all the examples, however, 

 whether testaceous or piceous the antennae retain their black tint. 



60. Strongylosoma subflavum, sp. n. 



Sumatra: Paningahan. Two male specimens. 



Closely resembling the preceding in its bifid anal sternite, the form 

 of the copulatory feet , and of the sternal lamina of the fifth somite , 

 in its slender build , colouration etc. ; but recognisable by the following 

 features. 



The keels are larger and more fia vous, the posterior angles being 

 more strongly produced; this may be clearly seen in the fifth somite, 

 where their posterior angles are produced well beyond the hinder 

 border of the dorsal surface; whereas in nigricorne the keels of this 

 segment are not produced beyond this edge of the dorsal surface. Again 

 in nigricorne the transverse sulcus of the tergites is strongly marked, 

 runs almost across the surface from keel to keel and is well-developed 

 on the 5 th somite. In subflavum , on the contrary , this sulcus is 

 weaker on all the segments and is somewhat feebly indicated on the 

 5 th and 6 th . 



61. Strongylosoma subnigrum, sp. n. PI. XXII, fig. 7. 



Sumatra: Manindjau. A single male example. 

 Closely related to both the preceding. Differs from nigricorne and 

 subflavum in that the lateral surfaces of the somites are pitch black, the
