escent ; they are striate, with the intervals convex and sub-carinate 

 in the anterior part ; under side fiavescent with the abdominal seg- 

 ments infuscate. Length 9-9-J mm. ; width 4-4 \ mm. 



Allied to the melanic form of A. tetragramma, Chaud., Catal., 

 p. 265, showing only faint traces of the fiavescent patches on the 

 elytra ; the colour of that part of the body seems, however, to undergo 

 a good deal of modification, but a good specific character is the 

 rounded posterior outer angle, which in A. tetragramma is acute. 



Hab. Natal (Malvern). 



i\.STATA CONSORS. 



Antennae, palpi, labrum, and prothorax testaceous-red, legs fiav- 

 escent, elytra piceous with a basal and lateral narrow fiavescent 

 margin ; head striolate longitudinally, neck smooth ; prothorax one- 

 third broader than long, rounded laterally from apex to past the 

 median part, and a little attenuate from there to the base ; disk 

 smooth ; scutellum reddish ; elytra one-third broader at the base 

 than the prothorax at its widest part, and gradually ampliated from 

 the shoulder to two-thirds of the length where they are twice as 

 broad as the prothorax ; they are depressed and striate with the 

 intervals convex and sub-carinate in the anterior part ; under side 

 and legs pale testaceous ; the three apical abdominal segments are 

 infuscate. Length 8 mm. ; width 4 mm. 



Eesembles much both the melanic form of A. tetragramma and A. 

 cognata, but is distinguishable by the width of the prothorax, which 

 is less broad in proportion to the length than in the two species 

 mentioned. 



Hab. Natal (Umlazi Eiver). 



Gen. LEBISTINIDA. 



Mentum with a distinct but short median tooth ; lobes nearly 

 straight inwardly, truncate at apex, rounded outwardly but strongly 

 emarginate near the apex ; ligula and paraglossae fused, trapeziform, 

 and straight at tip, the former with the two usual median setae, the 

 latter with a few setae at tip ; maxillary and labial palpi as in Lebis- 

 tina ; antennae very long ; shape of head, thorax, and elytra as in 

 Lebistina; tarsi long, second and third triangular, fourth dilated and 

 divided in two long lobes, the under surface is clothed with long, 

 closely set brown hairs, the anterior tarsi have two series of short 

 lamellae, and the claws have five teeth on each side.
