Head black, frons and back of head metallic green ; antennae black; 

 pterygodes black ; thorax black-brown, with a central metallic-green

 a central black spot on first segment, remaining segments black, last 

 two segments with lateral green spots ; wings hyaline-white, with 

 veins black ; primaries with costal, outer and inner margins, apex, and 

 a spot on the discocellulars rather broadly black ; a spot at base of costa 

 and a small diffused basi-subcostal litura metaUic green ; secondaries 

 with apex, outer and abdominal margins black, costal area grey-brown ; 

 pectus black ; trochanters and front of tibiae metallic green ; abdomen 

 nearly as above : expanse of wings 43 millims. 



Pacho, New Granada {Janson). Type, B.M. 



This species has a larger black spot on the discocellulars of 

 the primaries than any other known species. 



/. I. STILBOSTICTA, n. Sp. 



Head black, frons with two white dots ; origin of antennae and a central 

 spot on back of head white ; antennae black ; pterj'godes black, thorax 

 black, with a large central white spot on prothorax ; abdomen golden 

 yellow, with the three terminal segments black ; wings hyaline-white,

 base of costa and a white point near base of subcostal nervure ; secon- 

 daries with apex, outer, and abdominal margin black, costal margin 

 dark grey : pectus black, trochanters of front pair of legs white ; ab -

(5,$. Pacho, New Granada (Janson), Two specimens, B.M. 



Most nearly allied to /. fulviventris, but differing in its greater 

 size and the black anal segments of the abdomen. 



Genus Leucotmemis, n. gen. PI. XXVII. fig. 12. 



Allied to the preceding genus and to Mocliloptera, agreeing with 

 the latter in neuration, but diflFering from both in the great 

 size of the head and the very strongly pectinated antennae. 



Type L. latilinea, Walker. 



1. Leucotmemis latilinea = Glaucopis (Ilipa) latilinea. Walker, 



Lep. Het. i. p. 167. 

 Brazil (Bates). Type B.M. 



This species is coloured much like an llipa ; but its struc- 

 tural distinctions are seen at a glance.
