Mr. W. L. Distant on Homoptera. 65 



broadly rounded anteriorly, a fine central longitudinal in- 

 cised line on its basal area ; pronotum finely wrinkled, more 

 or less foveately depressed on lateral areas ; face centrally 

 longitudinally broadly granulose, the lateral areas strongly 

 transversely striate. 



Var. a. — Abdomen wholly black or piceous black. 



Var. b. — Vertex, pronotum, scutellum, apex of abdomen 

 above, and body beneath and legs ochraceous. 



Long., excl. tegm., 12i mm.; exp. tegm. 24-27 mm. 



Hab. Ecuador; Archidona (i/ae«5cA, Brit. Mus.) ; Bolivia 

 {Steinbach, Brit. Mus.) ; Peru (Brit. Mus.). 



I have fixed as type the specimen received as Breddin's 

 co-type, and named 0. venosula, an apparently MS. name. 



Oncomeiopia virescens, sp. n. 



Vertex, scutellum, abdomen above, body beneath, and 

 legs ochraceous ; pronotum and a spot at each basal angle of 

 scutellum olivaceous green ; apex of face and the clypeus 

 black ; tegmina dull olivaceous as far as the apical area and 

 obliquely truncately terminating a little before the transverse 

 veins defining the apical cells, between its outer margin and 

 the transverse veins defining the anteapical cells the colour is 

 darker and more purplish, apical area (extending inwardly 

 to apex of clavus) pale ochraceous ; wings pale fuliginous, 

 the disk hyaline, and the extreme basal area piceous ; vertex 

 smooth, as long as breadth between eyes, its apical margin 

 subtruncate ; face broadly longitudinally centrally flattened 

 and finely granulose, the lateral areas transversely striate ; 

 pronotum finely wrinkled, foveately depressed on each lateral 

 area; scutellum a little depressed near middle and with a 

 subapical dark spot. 



Var. — Abdomen above black, the lateral margins spotted 

 with ochraceous ; scutellum without the spots at basal angles. 



Long., excl. tegm., 14 mm.; exp. tegm. 27 mm. 



Hab. Peru (Brit. Mus.). 



The varietal form is represented by an unlocalized specimen 

 from the '' Fry Collection " now in the British Museum, and 

 is probably from Southern Brazil. 



Oncometopia brasiliensis, sp. n. 



Vertex ochraceous, the lateral and basal areas very pale 

 castaneous ; pronotum castaneous, mottled with ochraceous, 

 which colour is more pronounced on its anterior area; 

 scutellum ochraceous, its basal margin castaneous ; abdomen
