termediate tibiae, which is not posteriorly truncated as in P. Jammipes, 

 and also in the dilatation of the posterior tibise, wliieh is outwardly 

 rounded and not sinuated near the apex. The colour is also darker, 

 and the abdominal margin much more widely produced. 



Fam. Pyrrhocorid.e. 

 Roscius circumdatus, n. sp. (Plate XXXI. fig. A.) 



Black, apical portion of head, eyes, anterior, lateral, and posterior 

 margins of pronotum, and basal margin of coriura ochraceous or 

 testaceous, and two transverse fascise of the same colour on corium, 

 the first commencing at end of ochraceous basal margin and extending 

 nearly to claval apex, the second extending transversely across 

 near apex, and narrowly continued along inner margin to near claval 

 apex, the two fasciae thus almost enclosing a sublunate space. 

 Body beneath black, posterior margins of prosternum, mesosternum, 

 and metasternura, and three large spots on each side at coxae luteous 

 or creamy-white ; abdomen with the first three segments and apical 

 margins of the fourth, fifth, and sixth segments more or less luteous 

 or testaceous. Legs black, trochanters reddish. Rostrum reaching 

 fourth abdominal segment. Antennae black ; first, second, and fourth 

 joints subequal in length, third shortest.

Hab. Isubu, Calabar. 



This species is allied to R. quadriplagiatus, Schaum, hut differs 

 in the much more obscure and less deeply incised transverse incision 

 to tlie pronotum ; the body is also broader, of a different colour 

 beneath, and with the marking of the corium distinct. 



This would appear to be the 72. quadriplagiatus, var. ?, Walk. 

 (Cat. Het. V. p. 173. 3), from Congo. Walker, it is allowed by all 

 who follow him, had no reticence in describing species ; and the 

 only reason for his not doing so iu the present case appears to be, 

 that, at the time of his writing, he had not seen Schanm's species, 

 which is likewise confined to East Africa. 



Dysdercus antennatus, n. sp, (Plate XXXI. fig. 5.) 



Head sanguineous. Antennae black, apical joint with basal half 

 creamy-white, base of first joint spotted with sanguineous ; first 

 joint a little longer than the second, third shortest. Pronotum pale 

 luteous, anterior portion black, posterior with a transverse central 

 black fascia, lateral margin sanguineous, anterior margin |)ale luteous. 

 Scutellum black. Corium ociiraceous, thickly, finely, and darkly 

 punctate, with a broad black claval fascia, and outer margin creamy 

 white. Membrane black, with the basal angle obscure ochraceous, 

 and the apical margins creamy white. 



Head beneath sanguineous ; sternum black, anterior margin of 

 prosternum, posterior margins of prosternum, mesosternum, and 

 metasternum, and a large spot near coxae levigate creamy white, 

 lateral margins of prosternum sanguineous. Abdomen creamy white •
