 of the joints have a few spines. 



Pronotum of usual form, rather Hat, with an anterior transverse fovea on each side. 

 Mesonotaiu gradually widened to the middle, then gradually narrowing ; disk convi'X, 

 with a very faint impressed longitudinal central line. 



Ffont lc(js : femora rather stout, equally thick to middle ; tibia about tln-ee-fourths the 

 length of the femur ; tarsus (PL I. fig. S,f.f.) about three-fourths the length of tibia, first 

 Joint rather stout, about one-half the length of the second, which is cleft at the middle. 



Middle legs : femur armed on inner side with fine spines, alwut one-third shorter 

 than the tibia and tarsus taken together ; tibia about three-fourths the length of tlu; 

 femur; tarsus (PI. I. fig. 8, in.t.) rather more than one-fourth shorter than the tibia, first

 another more distinct one on the under inner side. Sometimes the whole femur below, 

 except at the apex and most of the first joint of the antennas below, is more or less jjalc, 

 but this may be from immaturity. Head with the sides and sternum on the sides,
