sides. The eyes are placed at the side of this pro- 

 jecting portion of the head. 



The mandibles are large, and strongly built ; the apical 

 tooth is large, long, and sharp ; there are two sub- 

 apical teeth. The labium is very nearly equally lobed ; 

 the first joint of labial palpi is small, half the length 

 of the second, and not much shorter than the fourth ; 

 third very nearly as long as the other three together. 

 Joints one, two, and four of maxillary palpi are sub- 

 equal in length ; the third is as long as these three 

 together, fifth longer than sixth, and nearly as long as 

 the third. 



The first radial cellule is longer than the second ; they 

 are long compared to the breadth. The transverse 

 radial nervure is a little oblique. The first cubital 

 cellule is long, narrow, of nearly equal width through- 

 out, and longer than the second, which is considerably 

 wider than it, especially at the apex. The third cellule 

 is a little shorter, and wider than the second. The 

 first recurrent nervure is received in the basal third of 

 the cellule, and is bullated at the junction with the 

 cubital. The second is received a very little in front 

 of the first transverse cubital cellule, and is often inter- 

 stitial. The transverse median nervure is interstitial 

 or nearly so. 



The legs are of moderate size. The tarsi are longer 

 than the tibias. The patellae are very well developed, 

 and somewhat membranous. The metatarsus is short, 

 but is longer than the second joint, the second, third, 

 and fourth joints become gradually shorter, the fifth 

 is longer than the basal ; its claws are strong, curved, 

 inflated at the base, and either simple, or with a blunt, 

 ill-developed, subapical tooth. In the $ the coxse are 

 much larger, thicker, longer, and more widely sepa- 

 rated ; the metatarsus is covered with long hair on the 

 underside, and the apex beneath is projected into a 

 large, blunt tooth. On the inner side the coxae are 

 hollow, their sides project into a ridge, which on the 

 posterior side and towards the apical third, curves
