By all the aixtbora I liave seen, tlie above have been placed as 

 synonyms of C. pnllidm, Westw. There is in this species, however, a 

 very constant character in a small, oblong, post-discoidal cell of the 

 corium, as shown in Westwood's fig.. Trans. Ent. Soc, ii, pi. 2, fig. 6 

 (1837), and as I have also seen, by an examination of the type with 

 Prof. "Westwood at Oxford. This does not exist in any of my speci- 

 mens ( (J or ? ) from Livingstonia, and the last joint of the antennae is 

 much longer than the third, thus also diifering from Westwood's fig. 

 This last character, and the larger size of the body, agree with Stal's 

 description of Goniehjtnim circuliventre, but I have used Spinola's 

 name as being the oldest and probably the correct one, thus following 

 Dr. Stal himself. 



EEDUVIID.^. 



This family is well represented in this small collection, and also 

 belongs to the East African fauna. Lestomerus csneicollis, figured by 

 Schaum in Peters, E-eis. Mossamb., is included, with its immature 

 forms. 



Catamia-RUS Ntass^, n. sp. 



Black, pilose, somewhat shining below. Hind lobe of prothorax obscure 

 chocolate-brown. Antennae pilose, first and second joints black, third and fourth 

 brownish, basal joints somewhat pubescent, second and third joints sub-equal in 

 length. Ante-ocular part of the head, basal joint of the rostrum, anterior part of 

 frontal lobe of prothorax, a triangular patch on each side of corium (of which the 

 bases are on the outer edges, and the points almost meet below apex of scutcllum), 

 six sub-quadrate spots on each abdominal boi'der (of which the apical one is small 

 and somewhat indistinct), apex of abdomen above, edges of abdominal segments 

 below (excepting on disc), a narrow spiracular longitudinal line on each abdominal 

 border, and legs (including coxse), densely silvery pubescent, somewhat yellowish on 

 upper side of body. Front lobe of prothorax longitudinally and rugosely striated, 

 with a distinct central longitudinal furrow, hind lobe confluently rugose. Membrane 

 somewhat opaque. Claws reddish-brown. Length, 10 lines. 



This is a very interesting species, belonging to a genus of which 

 only one other representative is as yet known, C. Irevipennis, Serv., 

 from Hindostan. 



There are some other new forms to be described ; but, in the 

 present discoloured condition of some of them, I prefer waiting for 

 fresh material before giving any further descriptions.
