with brownish and blackish punctnvation. Hind femora reddish-brown; the 

 externo-niedian area, creamy-white, ahnost smooth, with deep blackish punc- 

 tures scattered along- the middle, and with blaclc granulaied marj^inal carinae ; 

 the knees blackened laterall}'. Hind tibiae blackish on the underside, and 

 creamy-white, punctured with reddish-brown on the rest of their surface ; 

 their spines black-tipped. The underside paler and redder than the upperside. 



Length of body (somewhat extended) 72 mm.; prouotum S-e5 mm.; 

 elytra 1*5 mm. ; hind femora 23 mm. 



Two females (type and paratype) from Hermigua, Gomera, Canary 

 Islands, captm-ed 21. ii. 1922 Ly Mr. C. E. Bellamy, to whom the 

 species is dedicated. Both are in the British Museum collection. 



I have included this striking insect in the genus Orchamus, though 

 it does not agree very closely with all the generic characters ; thus, the 

 presence of a median carinula on the vertex and occiput, the extreme 

 reduction of the elytra, and the peculiar shape of the hind femora, may 

 be considered as characters of generic value. I, however, refrain from 

 describing a new genus until the male of the present species is known. 



The genus Orcliamus includes five species, and is restricted in its 

 distribution to the East of the Mediterranean — to Syria, Palestine, 

 Crete, and Cyprus, and that also speaks in favour of the new species 

 being generically distinct from the Eastern forms ; but there is no 

 doubt that it is much more closely related to them than to any genus 

 of Pamphaginae of N.W. Africa and Spain. 



It is very interesting to note that examples of the same kind are 

 known in the affinities of Canarian ffora. Thus, J. Pitard and L. 

 Proust * pointed out that the following endemic Canarian plants have 

 Eastern affinities: JRaniinculus corfiisaef'oliits Willd. io P. creficus L. 

 from Crete, and Parolina ornata W. to DicernteUa Jloccosa Boiss. 

 fi'om Persia and to D. canescens from Sokotra ; and that some- of the 

 Canarian Convolvuli are nearly allied to species of Asia Minor, Persia 

 and Sokotra. 



The fact that two odd specimens of Orthoptera, picked up by 

 Mr, Bellamy quite accidentally, proved to belong to a new and 

 extremely interesting species, indicates that our knowledge of the 

 Orthopterous fauna of the Canarian Islands is very unsatisfactory ; 

 indeed, the latest list of Canarian Orthoptera, by H. Ki-auss +, includes 

 64 species only, A\liile more than 200 are known from Morocco, the 

 fauna of which is scarcely richer than the Canarian one. A thorough 

 investigation of the latter is, therefore, badly wanted, the more so,
