Mr. W. L. Distant on Ilomoptera. 189 



Long., incl. tegm., 14 to 15 mm. 



Hab. Ecuador; Balzapamba (Brit. Mus.). 



Tlie British Museum possesses two specimens of this 

 species, purchased as one of '' Breddin's co-types " some years 

 ago, but I can find no trace of a corresponding description. 



Avernus affinis, sp. n. 



Allied to A. halteatus, Dist., but the colour pale castaneous, 

 not black, and the legs brownish ochraceous ; the tegmina 

 in addition to the white transverse fascia possesses three 

 white spots on the apical third — the first, largest and rounded 

 on costal margin, the other two more ovate and placed 

 on disk in longitudinal series before apex ; head and pro- 

 notum a little narrower than in A. balteatus, the latter also 

 finely granulose. 



Long., incl. tegm., 14 mm. 



Hah. Brazil (Fry. Coll., Brit. Mus.). 



Neoavernus, gen. nov. 



Vertex about as long as breadth between eyes, somewhat 

 broadly rounded in front ; ocelli at base, close to eyes, very 

 much nearer to eyes than to each other, the lateral and apical 

 margins a little upwardly ridged ; face without a central 

 carination; clypeus foveately depressed on each side at base; 

 rostrum slightly passing the intermediate coxse ; pronotum 

 with a central longitudinal carination which is more promi- 

 nent and distinct on disk, the anterior lateral margins 

 oblique, shorter than the posterior lateral margins, which 

 are slightly sinuate ; anterior margin roundly truncate, 

 posterior margin strongly subangularly concave in front of 

 scutellum, which is longer than broad ; posterior tibiae with 

 two strong spines ; tegmina twice as long as broad. 



Type, N. alhoater, Walk.
