the females in the series ranging from 25 to 30.5 mm. in the length of 

 the pronotum.^ 



After a comparison of sinensis with aridifolia there can be no doubt 

 but that they represent very distinct species. 



Genus POLYSPILOTA Burmeister. 

 1838. Polyspilota Burmeister, Handb. der Entom., II, p. 534. 



Included conspersa, alhimacula ( = Ma7itis domingensis Palisot), 

 varia {=pustulata Stoll), variegata { = striata Stoll), and catenata 

 { = pustulata Stoll). As only one, alhimacula, has been removed from 

 the genus, the type must be selected from the remaining four species. 

 As probably the best known and most representative form of the genus 

 is striata Stoll, variegata, which equals striata, may be selected as the 

 type. 



Polyspilota striata (Stoll). 



1787. [Mantis] Striata Stoll, Natuurlijke Afbeeldingen en Beschrijvingen, 

 Spooken, pp. 34, 78, PI. XI, fig. 41. [Coast of Angola.] 



Two females; Gaboon River, West Africa. (Rev. M. Nassau.) 

 [A. N. S. Phila.] 



While these specimens have been dried from alcohol, still it is evident 

 that two color phases, a light and a dark type, are present in this 

 species. 



Genus LEOMANTIS n. gen. 



Type. — Leomantis ignota n. sp. 



Allied to Sphodropoda Stal," but differing in the very much stouter 

 form, the very much wider costal field of the tegmina, the strongly 

 depressed head and peculiarly developed anterior femora. 



Leomantis ignota n. sp. 



Type: 9 ; Zulu Mission, South Africa. [A. N. S. Phila.] 

 Size medium; form very stout and robust. Head strongly com- 

 pressed, subocular in outline, though slightly longitudinal ; vertex very 

 narrowly rounded, arcuate when viewed from the front; eyes ovoid in 

 outline; ocelli small, disposed in a triangle; facial shield over twice 

 as wide as high, the superior margin very obtusc-angulate, the inferior 

 truncate; antenniB not quite equal to the pronotum in length, filiform. 

 Pronotum very stout, the greatest width equal to half the entire length ; 

 collar short, passing without any marked differentiation into the wide 



•'■' One female from the Mt. Airy colony exceeds any of the Japanese specimens 

 in size, measm-ing as follows: Total length 104; length of pronotum 31.4; length 

 of tegmina 64.5; length of anterior femora 24 mm.
