384 OETHOPTERA. 



2. Eriolus consobrinus, sp. n. (Tab. XIX. figg. 6, 7.) 



Minor, gracilis, viridis. Verticis rostrum longiusculum, conicum, apice hebetatum, primum articulum 

 antennarum dimidia parte superans, subtus haud acute carinatum. Capitis latera laevigata, lineis 

 rugulosis paucis; facies polita, infra ocellum punctis crassis nonnullis nonnunquam impressa; labrum 

 castaneum ; mandibulse apice et margine interno nigra?. Pronotum valde rugatum, postice breviter 

 productum, truncatum, margine postico vix arcuato ; lobi laterales angulo postico ad inferum producto. 

 Meso- et metasternum haud lobata. Elytra abdomen valde superantia, elevato-rugosa ; campo marginali 

 elevato-reticulato, venis costalibus 6-7 distinctis ; venis transversis in toto elytro flavicantibus. Femora 

 4 anteriora margine antico spinis 6, postico inermi; lobis genicularibus trigonali-productis. Femora 

 postica utrinque spinosa ; lobis genicularibus graciliter spinosis. 



2 . Ovipositor compressus, in medio latissimus, tenuiter rugulosus, valvis oblique truncatis, anguste fusco- 



limbatis; valvae superiores margine supero subsinuato, baud granulato, disco supra in medium linea 



granulata notato (nonnunquam deficiente). Lamina infra-genitalis vix sinuata. 

 6 . Segmentum anale supra planum, utrinque subcarinatum, profunde anguste incisum ; lobis apicalibus 



parallelis, apice obtusis. Cerci teretes, apice furcati, dente supero gracillimo, infero conico, longiore. 



Lamina infra-genitalis triangulariter incisa. 

 $ . Long. 19-21 ; pronot. 5*5 ; elytr. 28-30 ; femor. post. 12-13 ; ovipos. 8-9 millim. 



3 . Long. 17 ; pronot. 5 ; elytr. 25 ; femor. post. 11 millim. 



Figtjkes: — Fig. 6, the head and pronotum from above, magnified. — Fig. 7, the end of the abdomen and the 

 ovipositor of the female insect. 



Hab. Guatemala, Lanquin in Vera Paz, Capetillo (Champion); Panama, Volcan de 

 Chiriqui (Champion). 



This species is nearly allied to E.f rater, Redt., of South America; but it seems to 

 differ from that insect in having the process of the vertex reaching distinctly beyond 

 the first joint of the antennae. 



3. Eriolus falcatus, sp. n. (Tab. XIX. fig. 8.) 



$ . Minor, viridis. Facies polita. Verticis rostrum conicum, apice haud acutum, primum articulum anten- 

 narum vix superans, subtus convexum, haud nisi basi inter antennas carinatum, cum fronte contiguum. 

 Labrum castaneum, mandibulse intus nigrse. Pronotum subtiliter sparse punctatum, postice parum 

 productum, arcuato-truncatum ; lobi laterales rugulosi, margine infero subsinuato, angulo postico sub- 

 producto. Elytra angusta, ovipositorem superantia sicut in E. consobrino reticulata. Femora antica 

 subtus margine antico 4-, intermedia o-spinosa ; lobis genicularibus acutis. Femora postica extus spinosa, 

 intus tenuissime spinulosa, lobis genicularibus spinosis. Ovipositor angustus, valde arcuato-falcatus, 

 laevigatas, parallelus, basi haud sinuatus, apice longiuscule acuminatus. 



$ . Long. 12 ; pronot. 5*5 ; elytr. 25 ; femor. post. 11 ; ovipos. 6-5 millim. 



Figttee : — Fig. 8, the end of the abdomen and ovipositor, magnified. 

 Bab. Guatemala, Lanquin in Vera Paz (Champion). 



This insect somewhat resembles E. caraibeus, Bol., from Cuba, but it differs from 

 that species in its slender, strongly arcuated, shorter ovipositor, which is not dilated 

 in the middle. 



4. Eriolus acutipennis, sp. n. (Tab. XIX. figg. 9, 10.) 



Minutus, gracilis, viridis. Caput lsevigatum. Verticis rostrum subparallelum, primum articulum antennarum 

 leviter superans, apice rotundatum, subtus basi sinuatum, apice nodosum. Articulus primus antennarum 

 brevis, apice oblique truncatus, rotundatus, angulo interno fusco, rotundato, dente nullo. Pronotum
