432 Mr. W. L. Distant on 



dark castaneous. Head with the anterior margin narrowly 

 and obscurely ochraceous. Connexivum dull ochraceous, 

 broadly spotted with piceous at the junction of the segments. 

 Membrane bronzy brown, with some piceous shadings. Eyes 

 testaceous. Above and beneath thickly and finely punctate. 

 Antenna} with tiie second, third, and fourth joints subequal 

 in length, fifth joint mutilated. 



Long. 10 niillim. 



JJab. East Central Africa {Scott Elliot). One specimen 

 (Brit. Mus.). 



Shape and form of E. Jutulentus, Slal, but with the head 

 distinctly narrower. 



Genus JEnaria. 



^naria elongata. 



Pentatoma elongata, Dall. List Hem. i. p. 246. n. 34 (1851). 

 Niphe elongata, Stal, En. Hem. v. p. 73, n. 2 (1876) ; Letb. & Sev. 

 Cat. G4n. Hem. p. 114 (1893). 



The type of Stal's genus JEnaria is the Drinostia Lewisi, 

 Scott. I'he type of his genus Niphe I take to be Pentatoma 

 cephalus^ Dall. Stal divides his genus Ni^jhe into two sections 

 ■ — (a) " Jugis ante tyluni leviter prominulis," {aa) " Jugis 

 tyloque a^que loiigis." This course should also be applied 

 to yiiinaria, to which Pent, elongata, Dall., in my opinion 

 clearly belongs. The species of yEtiaria are thus understood 

 by myself : — 



a. Lateral lobes of tbe bead longer tban tbe central 



and meeting in front of same Lewisi, Scott. 



aa. Lobes of the bead subequal in length, central 



lobe sometimes slightly prominent assimulans, Diet. ; 



elongata, Dall. 



Tholosanus, gen. nov. 



Head broad, the lateral margins sinuate and slightly re- 

 flexed, lateral lobes slightly longer than the central lobes and 

 generally a little cleft between their apices, which are rounded. 

 Antenna? with the second joint distinctly longer than the 

 third. Pronotum slightly gibbous at base to about between 

 the lateral angles^ and then moderately deflected towards 

 head, the lateral margins very slightly convex, with the 

 extreme edges slightly laminate and reflected ; lateral angles 

 broadly, obtusely, convexly subprominent. Scutellum broad 

 at base, apex narrowed and convexly rounded. Corium with
