on 6 tlie lateral spines ave absent. Segment 7 has only two short central terminal spines. 

 The remaining segments are more slender, and unarmed. Operculum large, extending 

 considerably beyond the terminal segment. Legs rather long and slender ; front femora 

 with a single row of triangular teeth beneath, placed at about equal distances ; the 4th 

 largest; fovu" hinder femora with two rows of larger ones of five each on the under 

 surface. On the vinderside of the body there is a double row of short median spines.

HaJ). Archidona. 



This species appears to belong to Ccmlonia, but is much more spiny than any 

 previously described. C. hifoUa, Stal, probably approaches it most nearly in this 

 respect. 



Palophin^. 



This subfamily includes, inter alia, a series of interesting African Pliasmidcp, in which 

 the males are slender, with large wings ; and the females are stout, with shorter wings. 

 They have usually foliaceous or large spiny prominences on the legs, and the head is 

 crested, or more or less spined. The terminal segment is broad, slightly concave at 

 the extremity, and extends far beyond the operculum in the female. They are generally 

 classed under the genus Palophus, Westwood, but have been divided into several genera. 

 The genera already named are the following. (How far they are truly distinct Avill 

 best be seen when we receive more specimens of both sexes.) 



. . Palophus, Westw. 



Palophus, Westw. Cat. Phasm. p. 90 (1859) ; Brongniart, Nouv. Ann. Mus. Paris (3) xii. p. 193 (1892). 



The types are P. Haworthii, Gray (South Africa), and P. centaurus, Westw. (West 

 Africa). They have a long double pointed crest on the vertex, between the eyes, and 

 the thorax, though strongly granulated, has no raised spines. The second joint of the 

 front tarsi is lobate as well as the first. I have both sexes of these species before me, 

 but only females of any of the allied forms. These two species are perhajis not con- 

 generic ; for in the female of P. Haworthii the wings are no longer than broad, while in 

 that of P. centaurus they are nearly twice as long as broad, and the.mesothorax is much 

 longer and slenderer in proportion than in P. Saioorthii. But I do not propose to 

 separate these species generically, until more sj)ecimens are obtained. I imagine that 

 Palophus miiiotauriis, Gerstaecker, from the Gold Coast, is probably congeneric with 

 P. centaurus.
