810 Mil. W. L. DISTANT ON THE RHTNOHOTA [Nov. 20, 



are obtusely prominent at about the centre of the lateral margins, 

 from which the margins are concavely sinuate to apex. Scutelluin 

 about half the leugth of abdomen. Abdomen unarmed. 



I have placed this genus near Oerophara Stal, from which, apart 

 from other differences, it may be distinguished by the shape and 

 structure of the head. 



Kalula varicornis. (Plate LII. tig. 4.) 



CElia varicornis Westw. in Hope Cat. i. p. 33 (1837). 



Hal. Gambia. 



DlCTTOTUS SEHIMARGINATUS. 



Pentatoma semimarginata Westw. in Hope Cat. i. p. 42 (1837). 



Westwood gave no locality for his species, but the British

Antennae with the first and second joints ochraceous, third, 

 fourth, and fifth joints piceous, apices of tbird and fourth joints 

 ochraceous.

I have previously given the full synonymy of this species, but 

 now, from an examination of the Hope Collection, am compelled 

 to remove it one stage further back. 



DiCTTOTtrs pallipes. (Plate LII. fig. 9.) 



Pentatoma pallipes Westw. in Hope Cat. i. p. 41 (1837). 



In size and general appearance allied to D. roei Westw., but 

 having the head more elongate and not prominently cleft at the 

 apex, the central lobe being longer. 



Westwood's type is unlocalized, and I have not seen another 

 specimen.

Dictyotus affinis Dall. List Hem. i. p. 141. n. 4 (1851).

 the D. cequalis Walk.
