Tab. V, fig, 15 (forcipes). 
Diagn.:  Elongatus, dilute virescens, flavo-pubescens vel subpilosus, hemie- 
lytris pilis fuscis magis (g') minusve dense immixtis; vertice magis minusve 
(plerumqun  tamen distincte) marginato, carina maris parum arcuata, vertice 
maris oculo fere angustiore; oculis maris magnis, valde prominentibus et su- 
perne medio plerumque magis appropinquatis; rostro basin coxarum intermedi- 
arum attingente vel paullo superante; antennis praesertim maris crassiusculis, 
in certo lumine subtilissime densius fuscescenti-pubescentibus, versus apicem 
saepe (praesertim qg) obscuris vel fuscis, articulo primo capite breviore, se- 
eundo primo magis quam triplo (€) vel quadruplo (3) longiore, tertio secundo 
tantum fere 17, —1}, (g) vel !/,—1, (@) breviore et quarto 2!/, — fere triplo 
longiore, hoc primo longitudine aequali vel parum longiore; cuneo unicolore; 
membrana venis saturate viridibus; femoribus anticis margine inferiore setis 
longis exsertis; tibiis subtiliter pallide testacco-spinulosis; maris segmento ge-

Descr.: A praecedentibus corpore magis elongato et angusto distinctus, O. Ele- 
agni oculis magnis antennisque crassiuseulis maris maxime similis, differt autem carina 
verticis vix arcuata, vertice inter oculos adhuc paullo angustiore, structura antennarum 
nonnihil diversa, cuneo gutta basali aurantiaca destituto. Corpus elongatum, virescens, 
post mortem pallescens, superne longius flavo-pubescens vel sub-pilosum, pilis in certa 
directione Iluminis et praecipue a fronte visis fuscescentibus, vel pilis fuscis hic illic 
magis minusue dense immixtis. Caput pronoti basi circiter 1/, (Z) vel fere duplo (9) 
angustius, vertice maris plano, feminae convexiusculo, praecipue in mare distincte margi- 
nato, medio oculo fere augustiore, basin versus paullo latiore (4) vel oculo #/, — fere 
duplo latiore ($), fronte maris basi vertice angustiore, haud convexa, feminae leviter 
convexa; clypeo verticali, basi in linea inter scrobes antennarum dueta posita.  Oculi 
virescentes, post mortem saepe fusci, maris maximi, superne intus in verticem extensi, 
vertice convexiores et altiores, orbita interiore à basi verticis ad basin frontis conver- 
gentes, dein iterum divergentes et versus apicem profunde sinuati; feminae mediocres, 
orbita interiore in parte capitis basali subparalleli, dein minus fortiter sinuati. Rostrum
