 antennas luteous. 



Antennas with the second joint minute, third not quite twice 

 the length of fourth and subequal to fifth, third and fourth 

 joints flattened and sulcate. Head with the lateral lobes 

 convex at their apices, between which the anterior margin is 

 distinctly cleft ; the lateral margins sinuate. Pronotum with 

 the lateral margins convex and slightly reflexed, its surface 

 finely punctate and obscurely rugulose, especially near base. 

 Scutellum transversely wrinkled and finely punctate. Corium 

 obscurely wrinkled and finely punctate. Membrane dark 

 ochraceous. Coxae and disk of abdomen ochraceous. 



Long. 17-18 millim.; exp. pronot. angl. 10-11 millim. ;

Hah. E. Africa: Livingstonia (Simons, Coll. Dist.) ; 

 Nyasaland ; Fort Johnston (P. Rendall, Coll. Dist.), 



Allied by structure to the group of species having the 

 second joint of the antennas minute, viz. A. patrueliSj Stal, 

 A. cyclopeltus, Dist., and A. binotatus, Dist. 



Aspongopus singhalanus, sp. n. 



Bronzy brown ; antennas, eyes, rostrum, and legs piceous ; 

 apical joint of antennas, base of rostrum, and the tarsi 

 ochraceous. 



Antennas thick ; the second, third, and fourth joints deeply 

 sulcate ; second and third joints subequal in length or third 

 a little longer than second ; fourth and fifth joints subequal, 

 fifth joint narrowest and cylindrical. Body above finely 

 rugulose and punctate ; abdomen above reddish. Rostrum

Megymenum dentatum, Boisd. Voy. Astr., Ins. ii. p. 632, pi. xi. fig. 11 



(1835). 

 Megymenum instructum, Walk. Cat. Het. Hi. p. 502. n. 14 (1868). 



Walker had confused M. dentatum, Boisd., with M. semi- 

 vestitum, Voll., and then rcdescribed Boisduval's species.
