actions,' as well as the capture of both sexes of another 

 closely allied species in Borneo by Mr. Wallace, have proved 

 that Serville's speculations as to Parkinson's insect being 

 a female of the genus Eurycantha, of which males only, 

 supposed to be in an immature state (ultimately to become 

 winged), had been described, are entirely groundless, and 

 lead us to conclude, without doubt, that the male of II. 

 dilatata will be found to possess short tegmina and wings.

This species approaches as closely to II. Be Haanii as 

 the latter does to II. Mulleri, De H. It is, however, 

 very much larger (a number of specimens being uniform in 

 size), and is distinguished by the group of four spines at 

 the base of the tegmina, and the mottled appearance of the 

 latter. 



The general colour is reddish brown, obscure, slightly 

 rugose, and armed with numerous small and a considerable 

 number of larger spines, those upon the body of the male 

 being much stronger than those of the female, while the 

 legs of the latter are shorter, stronger, and more strongly 

 spined. The head is armed on its hind part with eight 

 strong spines, arranged in two rows ; the anterior lateral 

 angles of the prothorax have two strong spines, and there 

 are two near the hinder angles ; on the middle of the disc 

 in front are two erect diverging spines, and a transverse 

 row of spinelets near the hind margin. The upper surface 

 of the mesothorax has a somewhat elevated triangular 

 space, bearing a strong pair of spines in front, a pair in the 

 middle, and an elevated group of four between the places 

 of insertion of the tegmina; a raised line also runs ob- 

 liquely on each side from the fore angles to the base of the 

 tegmina bearing a row of minute spines, and the extreme 

 lateral margin bears about six spines on each side. The
