IPHIATTLAX. 341 



V 17. Iphiaulax gloriatorius. (Tab. XIV. fig. l, $ .) 



Luteus; eapite, prosterno, abdominis apice pedibusque, nigris; antennis fuscis, genieulis, tibiis tarsisque 

 anterioribus, testaceis ; alis fusco-byalinis, stigmate nigro, bifasciatis ; articulatione suturiformi recta. $ . 

 Long. 8 millim. ; terebra fere 8 millim. 



Hab Panama, Bugaba (Champion). 



Antennae covered with a close stiff pile, moderately stout, tapering towards the apex. 

 Face opaque, finely punctured, the sides densely pilose. There is a semicircular furrow 

 bounding the central part of the front, which has no furrow in the middle leading 

 down from the ocelli. The central part of the petiole is bounded by a sharp keel, and 

 has a depression on either side at the apex ; and in front of these are two shallow 

 depressions meeting at the apex. The central keel on the second segment is twice as 

 long as wide, and is bordered on either side by a wide and deep furrow, these furrows 

 not being united to the lateral ones. Suturiform articulation straight; the apical 

 branch issuing from near the middle ; curved, scarcely reaching to the side of the 

 segment. The middle cloud in the fore wing occupies the first cubital cellule, but is 

 narrowed obliquely towards the posterior side of the wing ; the apical cloud is broader 

 than the central one ; the recurrent nervure is interstitial. 



jb 18. Iphiaulax frugalis. 



Long. 10 millim. 



Hab. Panama, Bugaba (Champion). 



Very similar to /. gloriatorius, but larger and stouter ; the antennae much stouter 

 and thicker ; the depression on the front much deeper (being a regular depression 

 rather than a semicircular furrow surrounding a central part) ; the head more globular ; 

 the central keel on the second segment wider and shorter (not being double the length 

 of the base) ; the petiole flatter ; the clouds in the fore wings much darker in tint, and 

 the central one wider and not narrowed posteriorly ; the four anterior tibiae, and the 

 greater part of the tarsi, black ; the legs also stouter. 



The group of I. hectoe. 



The heel on the second segment in the form of an elongated triangle ; the lateral furrow 

 oblique, originating from the base, deep, wide; suturiform articulation usually finely 

 longitudinally striated. Wings blackish, or fuscous, wholly or in part ; the stigma 

 ochreous. (Species 19-24.) 



The black wings with ochreous stigma makes this division easily recognized.
