of the median segment, compressed in the apical two-thirds, subquad- 

 rate in section ; tibiae exceeding the femora by almost the length of the 

 pronotum, quadrate in section; metatarsi very considerably exceeding 

 the remaining tarsal joints in length. Median femora slightly exceed- 

 ing the metanotnm (with median segment) in length, subquadrate in 

 section, inferior margins with an irregularly rounded prebasal lobe, 

 genicular lobes acuminate; tibiae subequal to the femora in length, 

 quadrate in section; metatarsi considerably shorter than the remain- 

 ing tarsal joints. Posterior femora slightly exceeding the second to 

 fourth abdominal segments in length, subquadrate in section; tibiae 

 slightly longer than the femora in length, quadrate in section; meta- 

 tarsi but slightly shorter than the remaining tarsal joints. 



General color yellowish-brown (green in life?), becoming yellowish-

^^ There seems no escape from the substitution of this name for the species to 

 which the time-honored name Bacunculus has been applied. Gray's name has

 position has been definitely shown by Westwood (Cat. Orth. Ins. Brit. Mus., I, 

 pp. 25-26).
