Eab. Central Peru, Tarma. 



This species is remarkable on account of its very slender form and its pubescent pro- 

 notum and elytra. T. pilosella much resembles Ischnoptera inca, but differs from it in 

 the colour of the antennae, the pronotum being almost without impressions, the pubes- 

 cent elytra not having false intercalated veins, and also in the neuration of the wings.]

 pellucenti-testaceum, disco toto et margine postico castaneis, hoc vix arcuato, sulcis disci profunde im- 

 pressis. Elytra angusta, elongata, apice rotundata, rufo-castanea, parum opaca ; margine costali decolore. 

 Venae longitudinales mediae 2 parallelae : vena discoidalis ramos costales rectos longiusculos emittens 

 vena media ramos obliquos 7-8 ad marginem suturalem emittens. Campus discoidalis quadrato-reticu- 

 latus ; areis inter ramos per venas spurias divisis ; campus analis apice rotundatus ; vena analis vix sinuata, 

 ad 3 am partem marginis suturalis desinens vel ante illam. Alae leviter infuscatae, inter venas lineis 

 pallidis. Venae costales apice nodosae ; vena ulnaris ramos 4 ad marginem apicalem emittens. Area tri- 

 gonalis apicis minima. Pedes testacei, femoribus et tibiis supra linea brunnea marginata. Eemora 

 anteriora ut in typo Platamode spinulosa *. Abdomen plus minus testaceum. Lamina supra-analis com- 

 plete transversa, brevissima. Cerci longiusculi, fusci. Lamina infra-genitalis rotundata, stylis 2 brevis- 

 simis.

 pressionibus discoidalibus obsoletis. Elytra elongata, testacea, leviter rufo-fusco-umbrata ; vena humerali 

 basi et vena anali fuscis. Campus discoidalis in longitudinem 4-venosus, quadrato-reticulatus, in parte 

 obtecta elytri dextri fusco-reticulatus ; areis in elytro sinistro per venas spurias nullas divisis. Venulae 

 transversa? campi marginalis et discoidalis in medio interruptae. Campus analis piriformis, subacutus, 

 venis axillaribus 4 ultra 3 am partem marginis suturalis attingens. Alae leviter nebulosae, venis fuscis, 

 venulis costalibus 6 apice ovato-nodosis ; venae media et ulnaris leviter arcuatae, binae furcatae ; campus 

 replicatus apicis sat minutus. Pedes ad spinas fusco-punctati. Cerci testacei, basi, articulo antepenultimo
