Perisph.erid^. 



Derocalymma bottegiana Sauss. 



Central or East Soinalilaucl (1897). Two female specimens. 



1 cannot distinguish D. analis Sauss. from D. hotter/lana Sauss. 

 The former is merely referred to and inchided in the sjnioptical 

 table, which is A^ery difficult to follow. Mr. Peel's two examples 

 appear to agree entirely with the description of D. hottejiana 

 Sauss., which is described from Somali specimens. One of these 

 specimens still retains the yellowish velvet coat which is so easily 

 lost in handling. They are both a shade smaller than de Saussure's 

 types. 



Periplanetid.e. 



Blatia orientalis L. 



SomalJland (1895 or 1897). One female. 



PeRIPLANETA AMERICANA (L.). 



Somalilaud (1895 or 1897). One female. 



Mantodea.

CiiARiEis, gen. nov. 



Oculi conici, apice pedunculati. Caput 7iaud voids deprcssum. 

 Colore griseo. Ocelli in trian-jidum positi ; anteiince elonr/atfe, 

 r/raciles, festacece ; occiput convexum. Pronotum breve, sulcido 

 irregulari transversa instruction^ margine antico suhsinuato, 

 dilatato, margine postico rotundato, postice angustatum. Elgtra 

 et alee, perfecte explicatce. Ilia niembranacea, remote venosa, 

 hyalina, venis infuscatis, venulis transversis ramorum vence 

 radialis incrassatis, hicoloribus ; membrana analis brevis, sod 

 longior quam latior. Hie Jiyalinie, venulis arece anticce infus-

 libus 3 parvis armata, spinis marginis externa irregidaribus, 

 primo minima, 2" longiari, d'^-Q"-'"' parvis, dehinc margine

 subgenitalis 2 magna, fornicata, rotundata. Cerci $ sat longi, 

 laminam subgenitalem hand superantes. Lamina supraanalis

 This genus is a link between Brunner's two sections of the 

 Ortlioderid<v. In the form of the pronotum it agrees with CJuetessa 

 Burm., while the presence of small discoidal spines on the anterior 

 femora would place it in the second division. The conical and 

 pedunculated eyes, the spines of the anterior libiiB, the discoidal 

 spines, the somewhat long anal membrane of the elytra separate it 

 from Clio'tessa Burm. ; the form of the pronotum satisfactorily 

 divides it from the EremiapJiike, IliimhertieUce, and Chivapaclun. 



In general appearance and coloration it resembles Chiropaclia 

 and T'aracliodes, but it differs in the depressed head.
