IPHIAFLAX. 335 



nervure at its lower side ; the apical cloud commences on the outer side of the transverse 

 cubital nervure ; in the lower wing the middle cloud is exactly opposite that on the 

 fore wing, and the apical one is small ; the transverse basal nervure is received in front 

 of the first transverse cubital cellule ; second cubital cellule not one half longer than 

 the first and much shorter than the third. 



In this species the abdomen is shorter compared to the thorax and much broader 

 than in I. trochanteratus ; the raised space on the third segment is much more distinct 

 and extends as a carina to near the middle of the segment ; the head is not so much 

 nor so sharply narrowed behind the eyes, and the metathorax is yellow and the knees 

 black. The thorax also has not such a reddish tinge.

testaceis ; alis flavis, fascia medio apiceque fumatis, stigmate flavo. § . 

 Long. 11 millim. ; terebra 7 millim. 



Hob. Panama, Bugaba 800 to 1500 feet (Champion). 



Antennae longer than the body, the third and fourth joints subequal, the scape bearing 

 longish white hair. Face covered with longish white hair, irregularly aciculate, and 

 with a few punctures ; the centre broadly dilated ; vertex shining, impunctate ; the 

 ocelli slightly raised, surrounded by a furrow ; a deep and broad furrow runs down from 

 the ocelli to the antennas, this part too being slightly depressed ; teeth of the mandibles 

 inclining to piceous ; palpi pale testaceous. Meson otal sutures indistinct. Scutellum 

 raised gradually from the base and apex to the centre, longer than broad, shining, 

 impunctate, covered with longish hair. Metathorax short, rounded, densely covered 

 with pale hair, an oblique broad furrow on the pleurae ; a piceous band down the centre 

 of the metanotum. The centre of the petiole raised, separated from the side by a broad 

 and deep furrow ; a longitudinal, broad but not very deep, furrow down the centre. A 

 keel (broadest at the base) runs down the centre of the second segment ; a broad and 

 deep depression on each side of it, this depression originating at the base not far from 

 the central keel ; a short keel at the base, and a transverse depression on each side of the 

 next segment ; there is a shorter and more oblique depression on each side of the fourth 

 segment. ' Legs (especially the tibia? and tarsi) densely pilose ; the fore coxae are testa- 

 ceous; the apices of the joints of the anterior tarsi and the spurs pale testaceous. The 

 middle cloud in the fore wings commences at the base of the stigma, goes obliquely 

 across the base of the first cubital cellule to the first transverse cubital nervure, and 

 then follows the first recurrent nervure to the opposite side of the wing ; the apical 

 cloud commences at the end of the stigma, and forms a curve past the second transverse 

 cubital nervure. The cloud in the hind wings is opposite that in the fore pair, the 

 apical one is faint and narrow ; transverse basal and first recurrent nervures almost 

 interstitial.
