a dépression, slightly shorter than the anterior from which they 

 are clearly separated by the latler being depressed. Scutellum flat, 

 its base with a wide crenulated border. Metanotum rather flat, only 

 slightly sloping towards the apex, closely rugosely punctured ; the 

 spiracles small, oval. Mesosternum bordered by a narrow, but 

 distinct, almost smooth, furrow. VVings with 3 cubital cellules, the 

 radius issuing from the middle of the stigma; nervellus widely 

 post-furcal; the récurrent nervure interstitial, as is also the anal. 

 The 3 trans verse nervures in the hind wings are ail united. l st abdo- 

 minal segment forming a pétiole, but not much separated from the 

 2 nd ; it is cylindrical, slightly, gradually widened towards the apex 

 and is closely, transversely striated ; it is almost as long as the follo- 

 wing 3 united ; there is a narrow, smooth, roundly curved suturi- 

 form articulation. Legs long, slender; the 4 front tarsi about 3 

 times longer than the tibias; the calcaria and claws minute. 



This genus can only be referred to the Spathiinœ and to the Tribe 

 Spathiini. Its closest ally known to me is Habnoba Gam. from 

 Bornéo ; the latter may be known by the longer, narrower hind 

 coxae, which are 4 times longer than thick and of equal thickness, 

 linear, not oval viewed laterally; the front and vertex are not 

 deeply depressed in the middle and otherwise is easily separated by 

 the radial cellule in the hind wings being divided by a transverse 

 nervure, and the 2 nd cubital cellule is longer — as long as the 3 rd ; 

 the nervellus is almost interstitial. 



Rhopalospathius aurantieiceps n. sp. — Black, the head 

 and prosternum pale orange yellow; the apical three-fourths of the 

 antennee reddish brown; the base of mandibles broadly and the 

 palpi testaceous, the fore trochanters at the base and the greater 

 part of the femora rufo-testaceous; wings dark fuscous violaceous, 

 the stigma and nervures black; the basai abscissa of the radius 

 roundly curved, about two-thirds of the length of the 2 nd , the 3 rd 

 about twice the length of the basai 2 united. The récurrent nervure 

 interstitial. Ç. 



Length 18 mill. ; terebra broken.

Smooth, shining, the centre of the basai half of the middle lobe of 

 the mesonotum with an irregularly crenulated furrow, the base of 

 the rest closely reticulated, the sides striated, the strias curved at 

 the base. Metanotum closely longitudinally striated in the centre, 

 the strias running into reticulations; the sides closely transversely 

 striated. The top and base of metapleurae smooth, the rest irregu- 

 larly closely reticulated, the lower part punctured in front of the
