350 OETHOPTEEA. 



This species somewhat resembles II. trimaculata, Brunn., in the maculation of the 

 elytra, but differs from it in the longer ovipositor and in having the tympana of 

 the tibiae opened, not conchate.]

Hyperphrona bidentata, Brunn. v. W. Monogr. der Phaneropt. p. 319. 6 {$). 



§ . Majuscula, viridis. Antennarum articuli basales nigro-striolati. Verticis rostrum eompressum, sulcatum, 

 angustissimum. Carinae infra-oculares valde explicates. Pronoti canthi rotundati. Elytra latiuscula, 

 margine postico regulariter arcuato. Vena media valde ante medium oriens, valde ultra medium furcata. 

 Vena ulnaris cum ramo postico venae mediae per venulam brevem conjuncta, in origine ramorum maculis 

 3 purpureis notata. Campus dorsalis elytri dextri hyalinus, per venam longitudinalem crassam divisus ac 

 reticulatus. Ovipositor pronoto sesqui-longior, crasse granulatus, supra crassissime crenatus, subtus apice 

 minus fortiter denticulatus, rufescens, apice castaneus. 



Long. corp. 24; pronot. 5'5; elytr. 38, lat. 13; tib. interm. 11*8; femor. post. 21-6; ovipos. 8 millim. 



Hab. Guiana, Cayenne (Mus. Genavense).] 

 [4. Hyperphrona viridifolia, sp. n. 



§ . Viridis. Antennarum articulus primus margine apicali intus nigro, secundo intus macula nigra, articulis 

 sequentibus linea nigra. Verticis rostrum minutum, eompressum ; carinae infra-oculares condite explicatae. 

 Pronoti canthi rotundati. Elytra lata, margine postico magis arcuato. Elytra immaculata ; vena ulnaris 

 subrecta, apice rectangulatim deflexa. Ramus posterior venae mediae ad marginem posteriorem elytri 

 percurrens, cum angulo venae ulnaris per venulam brevem conjunctus. Campus dorsalis elytri dextri 

 subhyalinus, per venam longitudinalem crassam divisus, intus perpendiculariter, extus retro-oblique 

 venulosus sicut in H. bidentata. Vena media in medio vel paulo ante medium furcata. Ovipositor 

 pronoto valde longior, crasse granulatus, apice superne crasse denticulatus, denticulis magna parte acutis, 

 subtus apice crenatus, rufescens. 



$ . Long. corp. 28 ; pronot. 6-6 ; elytr. 38, lat. 14 ; femor. post. 19-5 ; tib. interm. 9-8 ; ovipos. 9*6 millim. 



Ilab. Guiana, Cayenne (Prudhomme). 



Differs from //. bidentata in the relatively longer ovipositor (compared with the 

 pronotum) and immaculate elytra; from H. ccerulescens * by the longer ovipositor; 

 and from H. striolata f by the intermediate tibiae being not nearly twice the length of 

 the pronotum.] 



5. Hyperphrona trimacnlata, Brunn. (Tab. XVI. figg. 20-24.) 



Hyperphrona trimaculata, Brunn. v. W. Monogr. der Phaneropt. p. 318. 4. 



Laete viridis, valde eompressa. Articulus primus antennarum extus basi, secundus intus basi, puncto eburneo 

 notati; flagellum rufescens. Verticis rostrum antice sublamellare, supra sulcatum. Irons convexa, 

 supra triangulariter terminata, carinis lateralibus obsoletis. Pronotum supra sulcis distinctis et sulco 

 longitudinali signatum ; canthis complete rotundatis. Elytra ultra medium latiBsima, margine suturali 

 arcuato, margine costali subrecto. Vena media longe ante medium oriens, tertia parte apicali furcata ; 

 vena ulnaris apice maxime recurva (ut Galli diount, en zigzag), et in ejus curvatione cum ramo venaa 

 mediae per venulam brevem conjuncta. Area ulnaris ad basin ramorum ulnarum maculis eburneis 3 



* H. ccerulescens : pronot. 5 ; ovipositor 6*5 millim. 



t B. striolata : tibiae intermedia? longitudinem pronoti duplicem attingentes : pronotum <? 6-5 millim.
