i64 HOMOPTERA 



We have not seen the single species of this genus and it has never been figured. StaFs description of 

 the genus, however, is full and complete and should sufftce for its recognition. The original description 

 is as foUows : 



« Corpus parvum, elongatum, valde subcylindricum, cohvexum. Caput ante oculos pro- 

 ductum, sensim angustatum, apice rotundato-truncatum et medio leviter incisum, sulco distincto 

 percurrente longitudinah instructum; facie convexiuscula, supra medium sulco longitudinah in- 

 structa; fronte apice biimpressa; genis ultra basin lororum haud longe extensis, margine medio 

 sinuatis, lateribus partia productas anteocularis capitus convexis, in faciem et partem sursum ver- 

 gentem sensim transientibus. OceUi in margine capitis ante oculos positi et ad hos valde appro- 

 pinquati, distinctissimi. Antennse infra oculos et in medio laterum faciei insertae. Thorax seque 

 longus ac posterius latus, valde convexus, antrosum sensim nonnihil convexo-decHvis, sexangu- 

 laris, carina percurrente distincta media instructus, prope basin latissimus, antrorsum nonnihil 

 angustatus, apice rotundatus, lateribus convexis,obtusissimis, in prostethium sensim transientibus, 

 marginibus basah et laterahbus posticus teque longis, marginibus lateraHbus anticis longissimis. 

 Scutellum multo longius quam latius, acute triangulare, carina longitudinah instructum. Teg- 

 mina coriacea, oblonga, apice rotundata, apicem abdominis attingentia, opaca, venis obsoletis. 

 Pedes breves; tibiis teretibus, inermibus, non nisi brevissime obsoletissimque setulosis vel 

 pilosuiis. » 



Type fuscata Fabricius. 



Geographical distribution : The habitat of the lone representative of the genus is indicated 

 merely as « America meridionalis » with no definite locahty given. 



I. fuscata Fabricius, Syst. Rhyng. 68. 3i (i8o3). South America. 



141. genus SCYTODEPSA STAL 



Scytodepsa Stal, Hem. Fabr. II : 57 (1869). 



Characters : Tiny, inconspicuous insects. distinguished from those of the preceding genus by 

 the subquadrate head and the hyahne tegmina. Head subquadrangular, about as broad as high, 

 trilobed at the apex; base straight; eyes small, flattened; ocelH large, conspicuous, located in the upper 

 outside corners of the head, very near the eyes and close to the basal margin ; inferior margins of 

 genae rounded and protruding to produce with the clypeus the trilobed apical outHne of the face; clypeus 

 extending for one-third its length below inferior margins of genae. Pronotum convex, without pro- 

 cesses; metopidium straight, about as wide as high, deeply impressed on each side to produce a 

 trilobed appearance; median carina strongly and sharply percurrent; humeral angles strong, swoUen, 

 rounded, blunt; no posterior process; scutellum entirely exposed, triangular, tectiform, sharpiy carinate 

 above, tip acute. Tegmina entirely free ; hyaHne or translucent; broadly rounded at apex ; five apical 

 ceUs; no discoidal ceUs; no apical Hmbus. Legs simple, very slender; all taisi about equal in length. 



Type exigua Fabricius. 



Geographical distribution : This seems to be a strictly South American genus with the 

 distribution of the three known species as follows : 



1. exigua Fabricius, Syst. Rhyng. 23. 36 (i8o3). — Pl. 9, flg. I 23. Brazil, Argentina. 



2. magiia Goding, Trans. Amer. Ent. Soc. LII : 889. 104 (1926). Ecuador. 



3. tricarinata Funkhouser, Journ. N. Y. Ent. Soc. XXV : 2. i63 (1927). Peru.
