apical half, and has a distinct furrow in the middle. 

 The four anterior legs are bright fulvous, their coxse and 

 femora white ; the hinder femora are of a darker fulvous 

 colour, darkened tov/ards the apex ; the coxa paler at the 

 base ; their apex broadly infuscated ; the tibise blackish, 

 the base pale testaceous ; the tarsi white, the basal third 

 of the metatarsus black. The areolet is nearly square ; 

 the second transverse cubital nervure is faint ; the recur- 

 rent nervure is largely bullated in the middle, and is 

 received shortly before the middle. Abdomen black ; the 

 base of the petiole broadly, its apex more narrowly, 

 almost the apical halves of the second and third segments, 

 and the apical segments entirely, pale white. 



The following species agrees closely in body form 

 with the preceding, and in the form and position of the 

 spiracles, but it differs in the antennae being much longer 

 (longer than the body), the joints being more elongate ; 

 the recurrent nervure is received near the base of the 

 areolet, which is longer. The base of the thorax is not 

 so distinctly raised above the head, which is as wide as the 

 thorax, and the median segment has the areae much 

 more distinctly defined.
