Ilah. Singapore [Bidley). 



Allied to B. trophinus^ Westvv., from Natal, but in the 

 male of that species the horns arc much more slender and 

 pointed, and the middle femora are unarmed. 



Subfam. III. Bacillinjj:. 

 Clitumnidce et Bacillidce, Brimner. 



The very short median segment and the large incurved 

 and frequently crossing cerci of the males will provisionally 

 bring together a series of apterous Old-World species which 

 agree with the American Diaphomerinas in most respects, 

 but differ in the shortness of their antennse. With Brunner's 

 Clitumnidge I associate his Bacillidse, considering them too 

 closely related to Phthoa &c. to be separated from them, 

 notwithstanding the more or less distinct excavation at the 

 end of the tibia?, which will, perhaps, prove to be a less 

 in)portant character than has been supposed. It is not nearly 

 so distinctly marked in some genera of Phasmida as in others. 



Another reason for removing the Clitumnida3 from the 

 position in which they were placed by Brunner is that they 

 come between the Necrosciinaa and Acrophyllinfe, winged 

 Old-World subfamilies which agree in the shape of the median 

 segment. 



Subfam. IV. DiAPROMERINM. 



Bacunculida, pt., Brunner. 



I employ this name for a series of American genera allied 

 to the Lonchodinaj by the very short and well-marked median 

 segment and to the Bacillinse by the large and generally 

 incurved cerci of the males, Bacunculus and the genera 

 following it in Brunner's arrangement appear to me to be 

 more closely related to the Bacteriinas.
