SAROPODA. 243 



jointed, about one-third the length of thp maxillse, the 

 basal joint short, robust, the second tapering from its 

 base to the third joint, -which is rather shorter, and sub- 

 clavate, the terminal joint slender. Thorax very pu- 

 bescent, rendering its divisions inconspicuous ; scutellum 

 and post-scutellum luuulate and convex; metathorax 

 truncated ; wings as in Anthophora, with three marginal 

 cells closed, the second forming a truncated triangle, 

 and receiving the first recurrent nervure near its centre, 

 the third bulging outwardly and receiving the second 

 recurrent nervure at its extremity ; legs very setose, 

 especially the posterior tibise externally, and their plantse 

 both externally and internally, but the setse are longer 

 on the exterior of the joint, the second joint of these 

 tarsi inserted beneath, and before the termination of 

 their plantse, the terminal joint longer than the two 

 preceding ; claws bifid, the inner tooth distant from the 

 apex. AbdOxMen subovate, very convex, truncated at its 

 base, where it is densely pubescent, the fifth segment fim- 

 briated with stifi' setse, and the terminal segment having 

 a central triangular plate with rigid setse at its sides. 



The MALE scarcely differs, excepting in the charac- 

 teristic sexual disparities of slightly longer antennae, and 

 considerably longer intermediate tarsi, whose apical joint 

 is very clavate.
