Genus Oxtpiltjs, Serville. 
The author considers that this genus should be transferred from the 
Mantidae to the Sarpagidae and therein placed between the genera Sestias 
and Sigerpes. Ceratomantis Sausswrii, W.-M., and Santis (Oxypilws) 
bicingwlata, De Haan, are shown to be closely allied Asiatic species of it, 
having the same relation to one another, as regards degree of development 
of the cephalic horn, as have Sestias Brunneriana and Sestias pictipes. 
Oxypilws has in common with Sigerpes the two posterior ocelli placed at 
the bases of spines. The author has only been able to study immature 
specimens of one African species, and if the perfect winged insects of these 
should hereafter be found to differ sufficiently from those of the Asiatic 
species to warrant their separation from them generically, the latter must 
take the name of Pachymantis proposed for the reception of De Haan’s 
Mantis bicingwlata by De Saussure.

5. Description of Sigerpes occidentalis, the Type of a new Oenus of 
Mantodea from West Africa.—By J. Wood-Mason. 
(Abstract.) 
In this short paper a new species of Mantodea closely related to the East 
African Sibylla tridens, Saussure, is described and made the type of a new 
genus, Sigerpes, which must be placed in the subfamily Sarpagidae next to 
the genera Oxypilws and Sestias. 
The cephalic horn, as was suspected by the author (P. A. S. B., 1876), 
turns out to be rudimentary in the males. 
The new species, described from a fine dried ? specimen in the British 
Museum from the neighbourhood of Sierra Leone, differs from Sigerpes 
(olim Sibylla) tridens ¥ in having the cephalic horn somewhat longer and 
without lateral lobes and teeth, the base of the wings greenish yellow, the 
fore tibiae more numerously toothed, the fore femora on the inside red 
tipped with black, and the extremities of the organs of flight not so ob¬ 
viously truncate. 
This paper will be published in the Journal, Part II, No. 4, for 1879.
