A NEW GENUS OF REDUVIID^. 



By E. Bergroth, 

 Fitchburg, Mass. 



Among some Hemiptera received some time ago from the des- 

 ert regions of northwest Argentina, there was a very remarkable 

 Reduviid, by its color, the structure of the short head and broad, 

 laterally not sinuated but reflexed pronotum and the whole facies 

 closely resembling a Coreid. So strong is the likeness that I had 

 placed it among my material of Coreidae, and it was not until an 

 attempt to determine it that its Reduviid nature revealed itself. 



Psammolestes gen. nov. 



Corpus robustum, oblongo-ovatum, opacum. Caput latitudine sua paullulo 

 longius, pronoto paullo brevius, parte postoculari anteoculari triple breviore et 

 nonnihil latiore, pone oculos lateribus callosa, basi subito constricta, parte anteocu- 

 lari aeque lata ac longa, inter oculos et apicem tuberculorum antenniferorum sub- 

 parallela, tylo apicem truncatum versus dilatato, jugis apicem versus divergentibus, 

 tylo aeque longis, oculis magnis, subglobosis, ma^jimam partem altitudinis capitis 

 occupantibus, ocellis atque oculis aeque late distantibus, ad hos valde approximatis, 

 tuberculis antenniferi se supero visis libere porrcctis et breviter cylindricis, antennis 

 ab oculis quam ab apice capitis paullo longius insertis, brevibus, basin pronoti 

 baud attingentibus, articulo primo brevissimo, incrassato, latitudine sua paullo 

 longiore, apicem capitis hand attingente, articulo secundo latitudini spatii interocu- 

 laris cum uno oculo subaeque longo, tertio secundo nonnihil breviore, quarto tertio 

 parte tertia breviore, rostro valde depresso, spatio interoculari inferiore latiore, 

 gulam subtangente, marginem anticum prosterni attingente, articulo primo medium 

 partis anteocularis attingente, secundo primo fere duplo longiore, tertio primo 

 paullo breviore. Pronotum transversum, apice vix sinuatum, marginibus lateralibus 

 rectis, reflexis, antice in tuberculum porrectum breviter conicum productis, angulis 

 humeralibus et basalibus rotundatis, non prominulis, impressione transversa disci 

 ante medium sita sat profunda sed latera non attingente, carinis duabus longitudi- 

 nalibus parallelis obtusis interrupta, his carinis antice in medium lobi antici con- 

 tinuatis, postice etiam in lobum posticum breviter productis, deinde retrorsum 

 leviter divergentibus et sensim obsolescentibus. Scutellum aequilateraliter tri- 

 angulare, leniter convexum, apice horizontali, vix producto. Sulcus stridulatorius 

 prosterni latus, leviter impressus. Mesosternum medio gibbum, parte gibbosa 

 longitudinaliter leviter impressa. Hemelytra abdomine angustiora. Abdomen 

 lateribus integrum. Pedes breves, antici leviter, posteriores magis distantes, 

 anteriores subaegue longi quam postici breviores, femoribus omnibus crassiusculis, 

 inermibus, posticis medium ventris nonnihil superantibus.
