between conspicuousness aud inconspicuousness with respect to the 

 excavation of the upper surface of the caudal segments. 



Fabricius' type of australasiae and Gervais' type of cumingii are 

 both preserved in the Natural History Museum. In the latter speci- 

 men the tail is more excavated above than it is in the former; but 

 otherwise there is no noticeable difference between the two. In his 

 description of cumingii, Gervais (Ins. Apt. Ill, p. 69) says that the 

 body is finely granular above. This, however, is not the case; for a 

 lens of sufficiently high power shows that what Gervais described as 

 granules are in reality exactly the opposite, namely punctures. 



Curiously enough the late Count Keyserling appears to have fallen 

 into precisely the same error. For although he describes the species 

 as granular, yet an examination of the examples in his own collection 

 shows that they are not granular but finely and closely punctured. 



11. Hormurus weberi sp. n. (PI. VI. fig. 1 — lb). 

 Several specimens from Luwu in Celebes. 



Colour — trunk above rufo-piceous ; palpi somewhat darker than the 

 trunk; legs and caudal vesicle and lower surface ochraceous. 



Céphalothorax usually a little longer than wide, at least not wider 

 than long, more convex from side to side than in H. australasiae, 

 closely punctured and finely granular, the frontal portion nearly smooth 

 and punctured, the lateral and posterior portions sparsely granular, 

 with smooth, neither granular nor punctured, areas; the middle third 

 of the anterior border deeply excised, the external thirds nearly 

 straight; the ocular tubercle deeply cleft, situated in the anterior half 

 of the céphalothorax; the median eyes large and very close together, 

 the distance between them being about half a diameter or even less; 

 lateral eyes large and very prominent, about equal in size and equi- 

 distant from each other. 



Tergites finely punctured, rugulose. 



Sternites finely punctured, entirely smooth. 



Tail about 2| times the length of the céphalothorax in Q and 

 nearly 2| in the cT ; the segments gradually increasing in length and 

 all of them longer than wide; the upper surface of all of them, ex- 

 cept of the 5 th , mesially excavated, the sides rounded, very weakly 

 granular, and noticeably without an enlarged terminal granule; the
