narrow dentate transverse black bands — the first before the middle 

 curves upward in front of the shoulders to the base, thus including 

 a large spot of the grouud-colour, at the sides it is connected with 

 a shoi't longitudinal stripe which also joins the second band 

 immediately below the middle : the third baud is placed near the 

 apex, but terminates abruptly at the sides, near its ends it is con- 

 nected with the intermediate band by a longitudinal stripe which 

 runs parallel with the suture, the latter is likewise narrowly 

 black. 



Hah. Malvern, Natal {G. Marshall). 



I cannot identify this insect with any other species of the genus 

 or their varieties previously described, although it is of course closely 

 allied to several, notably to^. 20-pustulata Thunb. ; but the pattern 

 of the elytra is different as well as the shape of the fulvous patches 

 which are surrounded by the black bands, and even if the latter 

 should in some specimens be connected in the places where the 

 short tooth-like projections seem to give indications, the pale spots 

 would be of different shape and position than in most other species ; 

 as it is, the three specimens exactly agree- except in the colour of 

 the thorax. The most characteristic distinction of the species wUl 

 be found in the laterally interrupted third band of the elytra and 

 its connection with the preceding band by a longitudinal short 

 stripe near the suture. P. pardalina Fab. is a somewhat closely 

 allied species which has the flavous elytral margin in common with 

 the present insect, but the position, number, and shape of the flavous 

 markings are quite different.

4. On a new Flagellate Protozoon of the Genus Lophomonas. 

 By E. H. J. Schuster, E.Z.S. 



[Received January 31, 1898.] 



In the year 1860 Stein established the genus Lopliomonas for 

 the reception of a Flagellate Protozoon observed by him inhabiting 

 the intestinal canal of Blatta oHentalis, to which he gave the 

 name Lophomonas hlaitarum. The same species was observed 

 shortly afterwards by O. Butschli under similar conditions. The
