OPHION. 293 



B. First cubital cellule with only one horny point. 



9. Ophion (Eniscopilus) guatemalensis. (Tab. xil. fig. 22.) 



Pallide flavus, alis hyalinis, stigmate pallide flavo. $ . 

 Long. 18 millim. 



Hab. Guatemala, San Geronimo (Champion). 



In its unicolorous body this species agrees with 0. concolor, but it is much smaller, 

 and the colour is more diluted in tint. Otherwise it differs in the metanotum being 

 much less strongly wrinkled, while there is no keel down its middle ; the scutellum is, 

 if anything, more gibbous, not so much narrowed behind, scarcely keeled at the sides, 

 and not punctured , but faintly striated at the apex ; the inner discoidal cellule is riot so 

 much dilated at the apical half (see figures), and in the first cubital cellule only the 

 pear-shaped horny point is present, it being also broader and shorter. 0. flavus may be 

 known from 0. guatemalensis by the deeper fulvous tint of the body ; by the middle of 

 the vertex being black ; the apex of the abdomen fuscous or black ; by the mesonotum 

 being punctured, the metanotum much more strongly wrinkled ; while the form of the 

 horny point in the fore wings is different, it being much more strongly pointed at the apex. 



2. No horny points in the fore wings (Ophion, sensu str.). 



A. Inner discoidal cellule elongated, more than three times longer than wide ; 

 first recurrent nervure without a branch. 



10. Ophion curvinervis. (Tab. XII. fig. 19.) 



Luteus ; capite, pleuris scutelloque, flavis ; alis hyalinis, stigmate luteo ; antennis nigro-brunneis. $ . 

 Long. 29-31 millim. 



Hab. Guatemala, Las Mercedes 3000 feet, Senahu (Champion). 



Antennae as long as, if not longer than, the body ; black, the flagellum more or less 

 brownish on the lower side, the scape sometimes luteous beneath. Head shining, 

 obscurely punctured, not much projecting in the middle; clypeal fovese deep, longish. 

 Thorax covered with close pale pubescence. Mesonotum very minutely punctured, the 

 pleurae finely longitudinally striated. Scutellum carinate along the sides. Metanotum 

 with one transverse keel near the base ; the base behind it finely rugose ; the rest of the 

 surface finely rugose, and bearing arcuate keels. Metapleurae finely rugose. Petiole 

 shining, glabrous, slightly hollowed in the centre above at the base ; postpetiole clearly 

 separated from, and distinctly thicker than, the petiole, densely covered with a white 

 pubescence ; the petiole itself is narrowed at the apex ; together they are nearly as long 

 as the second segment, which is dilated at the apex. The kamrvcrua - radial nervure is 

 curved upwards in the middle on the basal division, the apical portion having a
