 convexum, rotundatum, inter antennas obtusum ; rostro nullo ; facie oblique planula. Scutellum faciale 

 transversum, breve ; ejus processus frontalis quam antennarum primus articulus vix aequilatus. Oculi 

 subovati, anterius prominuli. Vertex inter oculos vitta lata callosa albida ; bac margino infero in medio 

 pro ocello sinuata, "utrinque ad ilium tuberculum subtilem formante. Ocellus intermedins elliptico- 

 transversus, ut videtur unicus (nisi ocelli laterales sint minimi ad oculos positi ?). Pronotum transversum,, 

 margine postico leviter arcuato, utrinque leviter sinuato ; lobis lateralibus altis, rotundatis. Elytra 

 elongata, in dorso parum lata, parallela; ad venas utrinque fusco-umbrata, venis partim fuscis, vel 

 diverso modo fusco-umbratis vel maculosia. Can thus lateralis campi dorsalis acutus, per venam discoi- 

 dalem fuscam eifectum. Area medio-discoidalis latiuscula, parallela, per venulas divisa, in venulis maculis 

 transversis fuscis tessellata. Campus baseos elytri (analis) venulis transversis fuscis reticulatus. Venae 

 obliquEe sunt : a, 2 transversa extus leviter divergentes; b, insuper in angulo areas discoidalis, venulae 

 minutae 3. Speculum fere seque latum ac longum, antice in medio rectangulum, postice parabolicum ; 

 paulo ante medium per venam transversam, extus subangulatam, divisum. Area involvens intus leviter 

 latior ; vena involvens cum margine externo speculi fusa. Vena postanalis venulam brevem ad venam 

 diagonalem, alteram ad speculi angulum, emittens. Area apicalis longissima, sectoribus 4 sigmoidalibus, 

 ac irregulariter reticulata. Campus lateralis perpendicularis, membranaceus ; vena bumeralis in medio 

 venae mediastinal contigua ; rami venas niediastinae marginem inferum haud attingentes ; intermedii 

 arcuatim, ultimi fere rectangulatim, confluentes ; intermediaa 2, 3 flexuosse. Alae longiuscule caudatae. 

 Pedes fulvo-pubescentes ; antiei et intermedii breves. Tibiae anticae vix dentatse, supra subplanulae; 

 tympano extus elliptico, intus anguste oblongo, pubescente. Femora postica brevia, modice crassa ; tibiae 

 quam ilia paulo longiores, spinis 6 : 4, spinulis inter spinas in margine interno 1 vel 2 obsoletis, in 

 margine externo 3:2:2 fortioribus ; calcare supero-interno quam intermedium ^ longiore. Metatarsi 

 breves, supra spinis 1 : 2, apice calcaribus 2 longis, validis, armati. Spinas ac spinulae pedum minute 

 fuscae. Lamina supra-analis trilobata, trilobato-impressa, marginibus lateralibus ante medium sinuatis, 

 lobis basalibus extus rotundatis ; lobo apicali producto, rotundato, V-formi ; marginibus omnibus leviter 

 prominulis. Lamina infra-genitalis elongato-trigonalis. 



J . Long. corp. 15-7 ; pronot. 3, latit. in medio 14-5 ; elytr. 21*5 ; femor. post. 12-5 mill. 



Hab. Guiana, Cayenne (Mus. Genavense; Prudhomme). 



This large species probably extends, like Eneopterus surinamensis, into the northern 

 parts of South America and also to Panama. The male of this genus was previously- 

 unknown, and I have taken the opportunity of describing and figuring one here. The 

 tympanum of the elytra resembles that of Orocharis, Apithes, and the allied genera 

 (Tab. XIII. fig. 23, a, */); but the inner nervure of the vence transversa, broken at a 

 right angle, is prolonged somewhat beyond the second outer branch (Tab. XIII. fig. 1). 

 The lateral field is reticulated at the base by transverse venulae, and between them 

 by irregular incomplete veins. — This insect cannot be the male of P. mortuifolia, on 

 account of the corneous whitish callosity between the eyes.]
