Hab. Guatemala, Las Mercedes 3000 feet, San Isidro 1600 feet (Champion). 



Antennae longer than the body, closely pilose. Head impunctate. Mesonotum 

 tinged with black in the centre, shining, impunctate. Scutellum longish, narrowed 

 towards the apex, the sides keeled, the back irregularly longitudinally striated. Meta- 

 notum with a transverse keel towards the basal half, behind which it is smooth ; in 

 front of it coarsely reticulated and bearing in tbe centre keels, which are straight at 

 the base and then diverge towards the sides. The two basal segments of the abdomen 

 are subequal ; the first becoming gradually thickened towards the apex. 



8. Ophion (Eniscopilus) maculipennis. (Tab. XII. fig. 29.) 



Flavus, maculis 3 mesonoti, sternoque nigris ; alis hyalinis, fascia substigmatali fusca. $ . 

 Long. 18 millim. 



Eab. Panama, Bugaba (Champion). 



Antennae longer than the body, yellow, fuscous towards the apex. Head impunctate, 

 shining. Mesonotum finely and closely punctured. Scutellum more strongly punc- 

 tured, strongly keeled down the sides. Metanotum behind the transverse line finely 

 punctured ; in front of it coarsely transversely rugose ; mesopleuree closely punctured. 

 The pro-, meso-, and metasternums are black ; the black on the mesosternum extends 

 halfway up the mesopleuree, and is continued in the middle as an oblique band to the 

 hind wings. There is a black mark on the underside of the middle coxae, a larger one 

 on the hinder coxae, and the apical half of the petiole is more or less black ; the third 

 and following segments incline to fuscous above. The stigma is black, except at the base 

 and apex, where it is yellow ; the costa is yellow ; the other nervures black ; the 

 anterior horny point is distinct, about one half longer than broad, and obliquely trun- 

 cated at the apex. The legs are clear pallid yellow. 



A distinct and well-marked species.
